Tytuł:: 95-lecie Morskiego Instytutu Rybackiego: aktualne tematy badań naukowych. Tom II. Stan środowiska południowego Bałtyku
Autorzy:: Psuty, Iwona
Data publikacji:: 2016
Wydawca:: Morski Instytut Rybacki - Państwowy Instytut Badawczy
Opis:: Książka przedstawia wybór wyników badań z szerokiego zakresu analiz środowiskowych Morza Bałtyckiego realizowanych w MIR – PIB. Za najpoważniejszy problem Bałtyku uważa się jego eutrofizację, za którą według HELCOM to nadal Polska ponosi największą odpowiedzialność, wprowadzając ładunki biogenów pochodzących z nawozów rolniczych wodami Wisły i Odry. Kompleksowa analiza danych i parametrów modeli podważa taką tezę. W tomie przedstawione są również prace dotyczące innych parametrów środowiskowych (warunki tlenowe, zasolenie), biologicznych (sieć troficzna, zapasożycenie) i antropogenicznych (trwałe zanieczyszczenia organiczne) wpływających na funkcjonowanie ekosystemu Bałtyku lub uważanych za groźne (amunicja chemiczna).

Wydawca:: Morski Instytut Rybacki - Państwowy Instytut Badawczy
Opis:: Książka prezentuje prace dotyczące problemów tego sektora rybnego z uwzględnieniem jakości i bezpieczeństwa surowca, w szczególności ryb pelagicznych z Bałtyku, które mogą być w większym zakresie przetwarzane na cele konsumpcyjne. Duży wpływ na możliwości zwiększenia produkcji ma popyt konsumentów, którzy bywają wprowadzani w błąd doniesieniami medialnymi o substancjach niepożądanych w produktach rybnych. Z tego powodu w monografii przedstawiono dwie prace dotyczące wyników analiz chemicznych ryb i produktów rybnych dostępnych na polskim rynku. Cykl badań dopełniają analizy funkcjonowania łańcucha dostaw ryb bałtyckich, a także prezentacje niewykorzystanego potencjału gospodarki cyrkularnej, wykorzystującej do dalszej produkcji surowce odpadowe.

Opis:: Wobec dużych kontrowersji ujawnionych w okresie konsultacji społecznych zaproponowanych programów ochrony ptaków przed śmiertelnością powodowaną przez rybołówstwo pomiędzy zespołem przygotowującym te programy, Ministerstwem Środowiska i organizacjami pozarządowymi a rybakami poławiającymi na obszarach morskich wód wewnętrznych i przybrzeżnych Polskich Obszarów Morskich, Zarząd Zrzeszenia Rybaków Zalewów Szczecińskiego, Kamieńskiego i Jeziora Dąbie, wystąpił o środki do Programu PO Ryby, na sfinansowanie pilotażowego monitoringu przyłowów w rybołówstwie przybrzeżnym (jednostki do 12 m długości) na trzech obszarach NATURA 2000 – Zalewie Szczecińskim i Zalewie Kamieńskim, Zatoce Pomorskiej oraz na Zatoce Puckiej. Niniejsza monografia stanowi podsumowanie wyników realizacji tych badań.
In view of large controversies revealed during public consultation on programs proposed for bird protection against mortality caused by fisheries between a team preparing these programs, the Ministry of the Environment and non-governmental organizations and fishers performing catches in the internal sea and coastal waters of the Polish Marine Areas, the Board of Fishers Association of Szczecin and Kamienski Lagoons and Dąbie Lake applied for funds to the operational program “Fishes” to finance pilot bycatch monitoring in the coastal fisheries (vessels up to 12 m in length) in three areas of NATURA 2000 – the Szczecin Lagoon and the Kamieński Lagoon, the Pomeranian Bay and the Puck Bay. This monograph is a summary of the results of these studies. The most important assumption, which distinguishes the presented monitoring from other programs of this type, was to base it on real data on fishing effort expressed in net-meter-days (NMD). The system of registering fish catches in Poland enables this approach instead of relating bycatch to the number of vessels, which used to be a practice in previously published works. As the preliminary analysis of data from the Fisheries Monitoring Center (FMC) showed, raw data from this source are not useful for calculating the fishing effort of the coastal fisheries performing catches with gillnets, necessary for the implementation of these project objectives. The most serious obstacle preventing the direct use of the data from the FMC was the inability to select records due to the type of nets, while this is an important variable determining the size of the bycatch of birds. However, the type of gear could be inferred indirectly based on a mesh size and target species of the catch or on the basis of the catch composition (the dominant species). Unfortunately, the mesh size and target species are not required data in monthly catch reports. The assignment of records to the type of nets required a detailed analysis of the catch composition. Due to the fact that estimating the size of the bycatch of birds in relation to the total fishing effort requires the use of a standardized effort unit (net meters/catch day), it was necessary to verify and supplement the records in the FMC database by the number of fishing gear and the time of catches. In the course of a detailed analysis of the database and during direct fishing observations it was shown that there is a very large variation in the characteristics and the size of fishing effort between individual fishing vessels and depending on the month of catches. During the observations it was found, for example, that the length of nets used by fishers ranged from 70 to 7700 m and the catch time from 2.5 to 216 hours. In turn, in the course of a detailed analysis of the FMC database, it was stated that the activity of vessels during the months covered by the analysis (October–April) ranged from several to 264 catch records. Thanks to basing on the actual fishing effort it was possible to determine a representative number of observed cruises broken down into fishing bases and modeling the obtained bycatch quantities and into the total fishing effort realized in a given sea area. The monograph presents the conditions of the coastal fisheries in the analyzed areas of NATURA 2000 including: the diversification of fishing vessels, types and techniques of nets’ servicing, reporting obligations and the spatial and temporal limitations resulting from the regulations governing the fisheries that occurred during the implementation of the research. The methodology of the detailed analysis of the FMC database covering the selection, verification and filling of gaps in the data was discussed in detail. For the purpose of specifying a representative scheme for the research effort, the fishing activity expressed in the number of records referring to the return to a port with catches in 2013 (January–April and October–December) was taken into account. The largest number of catches was recorded in the Puck Bay (5808), then in the Pomeranian Bay (2978), and the least in the Szczecin and Kamienski Lagoons (1322). The project provided for financing the observation of 120 cruises, therefore it was decided that in the case of the Pomeranian Bay, only a reconnaissance in the coastal zone in the area of the Świna and Dziwna estuary would be conducted within the project. A total of 37 fishing vessels participated in the research period from November 2014 to April 2015. In the Szczecin Lagoon and the Kamienski Lagoon, the observers participated in 58 catches with the overall effort of 358 678 NMD, representing 5.6% of the fishing effort registered in this area from October 1, 2014 to April 30, 2015. In more than 80% of net sets, no bycatch of birds was found. In total, 137 bird specimens were recorded. Greater scaup Aythya marila were the most abundant (69 indiv. caught), then great crested grebe Podiceps cristatus (29 indiv.), and common goldeneye Bucephala clangula (15 indiv.). During the analyzed period, the total fishing effort in the Szczecin Lagoon was 5 974.4 thousand NMD, with pikeperch and perch-roach gillnets as the most commonly used gear, in the Kamienski Lagoon it was only 370.2 thousand NMD with the dominance of pikeperch gillnets. There were 52 active vessels in the Szczecin Lagoon and 9 in the Kamienski Lagoon. In the Pomeranian Bay in the area of the Świna and Dziwna estuary there were 15 cruises and the fishing effort amounted to 49 170 NMD. In almost 70% of the net sets, no by-catch was found. In total, 91 birds were registered, including one case in which for one set there were up to 13 long -tailed duck Clangula hyemalis. It was the most frequently caught species (68 indiv.). In addition, greater scaup (14 indiv.) and common scotter Melanitta nigra (13 indiv.) were registered in a greater number. In the Pomeranian Bay, 110 vessels up to 12 m in length operated in the course of the research, with the fishing effort of 14 953.1 thousand NMD. Cod gillnets’ were the most frequently used. At the Puck Bay, 105 cruises covering 196 558 NMD were observed, representing 1.2% of the total fishing effort registered in the FMC. In over 92% of the net sets, no bycatch was found. In total, 66 birds were registered, including mostly long-tailed duck (16 indiv.), velvet scoter Melanitta fusca (13 indiv.), razorbill Alca torda (12 indiv. including 10 indiv. in one set) and common goldeneye (11 indiv.). In the Puck Pay, in the course of the research, 161 vessels operated and spent 15 932.6 thousand NMD. Cod gillnets were the most often used, trout gillnets and flounder gillnets were also frequent. Based on the data from observations, the optimal generalized linear regression (GLM) model of bycatch was tested and iteratively selected using the AIC and BIC information criteria. Additionally, the collinearity of explanatory variables was analyzed. The model was constructed on the basis of the bycatch size (explained variable) and: the catch period (month), water basin, type of gear, length and time of exposure, depth and distance from the shore of the catch site (explanatory variables). The analyzed explanatory variables were characterized by a strong asymmetry with a large number of "zero" values. As a result of testing the models, it was shown that the optimal model describes the bycatch as statistically significantly dependent on: water basin, month, type of gear and length of the net set, while the latter parameter was interchangeable with the effort expressed in NMD. With the use of this model, the prediction on the bycatch of birds based on the data on the fishing effort from the FMC from the research period (October 2014–April 2015) and the period a year earlier (October 2013–April 2014) was made. In the Puck Bay, the bycatch of birds in the seasons 2013–14 and 2014– 15 was estimated on the basis of a model at the level of 3359–3173 individuals. Cod gillnets were the most responsible for the bycatch due to the largest fishing effort of this type of nets registered in the FMC database. In the Szczecin and Kamienski Lagoons, the bycatch of birds was estimated at the level of 2487– 2930 individuals, in the 2013–14 and 2014–15 seasons, respectively. Pikeperch gillnets were the most responsible for the bycatch, both due to the highest model average bycatch as well as the largest fishing effort of this type of nets recorded in the FMC database. The values shown differ significantly from those presented as the justification for the significant impact of the fisheries on the bycatch of birds in both areas of NATURA 2000. An overstatement of birds’ mortality might have resulted from the lack of analysis of the actual fishing effort in previous surveys. It should be emphasized that with the current system of reporting catches by vessels up to 12 meters in length, the estimation of the fishing effort is extremely time-consuming and requires extensive knowledge of current fishing practices. In the discussion, a provisional estimate of the bycatch scale was made in relation to the NATURA 2000 areas identified as part of the wildlife inventory of birds exposed to bycatch (species found during fishing observations and/or reported in fishing registers). In case of the Szczecinski and Kamienski Lagoons, the bycatch problem may concern 2.4% of local populations of these bird species and 6.6% in case of the Puck Bay. However, these values should be verified on the basis of simultaneous monitoring of seasonal abundance of birds and the bycatch monitoring. The possibility of observing catches from the board of an accompanying vessel and using video monitoring was also examined within the project. The first option was excluded due to the safety of the vessels at a distance allowing the observation of a fishing operation. The second method, despite many technical problems, has the potential to be used for the bycatch monitoring. In addition, the method of voluntary bird bycatch registers, both in paper and electronic form, was also tested. Online register with the guide to identify birds has not been used by any fisher. 35 paper registers were obtained. They were also distributed with the bird identification guide. A total of 1514 fishing records were entered, during which fishers found 802 bycaught birds. In the data part there was no information necessary to calculate NMD – the catch time or the length of nets. Many records could not be assigned to the type of nets. Despite these problems, in the opinion of project implementers, bycatch registers may be an important source of information on the bycatch of birds, as long as the fishers maintain a regular contact with the institution collecting this data, and these reports would be remunerated due to an additional burden. The monograph describes the results of a survey of attitudes and beliefs of fishers regarding the protection of seabirds. The survey consisted of 14 questions, including open ones. 138 fishers from 33 fishing bases took part in the research. The results clearly indicate a crisis of confidence among the fishers, especially those from the Puck Bay region, to scientific institutions in connection with the project of closure of fishing grounds during migration and wintering of sea birds.

Opis:: Asian countries produce the majority of the macroalgae biomass and also cultivate the greatest diversity of seaweed species. Although more than 200 species of macroalgae are exploited commercially, five genera represent approximately 98% of the world seaweed production. Macroalgae are commercially processed mainly for food products and production of hydrocolloids. However, due to the presence of various valuable compounds, which are suitable for e.g. pharmaceutical, biomedical or cosmetic industry, more and more new products are available on the market and additional ones are in the research phase. In 2005-2015, the global production of seaweed doubled, but in 2016-2018 the dynamics of the development of seaweed production decreased significantly. The vast majority of production is made in Asia. Europe accounts for less than 0.1% of the world’s seaweed cultivation. In the Baltic Sea Region, apart from the western waters on the border of the North Sea, only a few experimental farms are conducted. On a small commercial scale, the wild seaweed in the Baltic Sea is fished only in Estonia and Denmark (1.2.) There is little documented evidence of seaweed consumption prior to the 20th century in the Baltic Sea Region. In the 20th century, consumption of seaweed spread to the Eastern Baltic Sea, along with the Soviet cuisine, into which seaweed was introduced by the Korean diaspora. In the last 3 decades, there has been a sharp increase in interest in seaweed throughout the Baltic Sea Region, due to the growing popularity of Far Eastern cuisine, mainly Japanese (sushi). Currently, seaweed products are appearing more and more often on the market of the Baltic Sea Region - not only in Far East gastronomy, but also in the retail market (retail chains, specialist health food stores, less often - fish stores) - in the form of salads (loose and packed, in different flavors), dried products (including various snacks), as well as a number of innovative multi-ingredient products. There is also a wide availability of dietary supplements based on seaweed. Seaweed products are quite commonly known to consumers in the Baltic Sea Region - due to studies conducted during GRASS project, 26% of consumers in the Baltic Sea Region have already eaten seaweed, but only as an ingredient of sushi, while nearly every fourth (23%) consumer has already tried seaweed also in other forms (e.g. salads, soups, snacks). As many as 34% of consumers declare that they “could try to eat” seaweed food products. Over 30% of consumers in the region believe that seaweed is food with particularly high pro-health values. Combining this data with the great interest of consumers in the region in products with guaranteed local (regional) origin, it must be determined that seaweed food products have great market potential. Algae can constitute new sources of functional compounds for food chain but also could be useful in various industries, as valuable raw material for: • cosmetics and cosmetology industry, • medical and pharmaceutical industry, • agriculture (fertilizers, bio-stimulants), • biofuel production, • many other industrial applications. Seaweed is a raw material that, due to its numerous properties, is very versatile. Thanks to its high nutritional value (a rich source of proteins, essential amino acids and vitamins necessary for the proper functioning of the body), algae are widely used in food production. A diet rich in algae meets the needs for protein, essential amino acids, minerals and vitamins. As they are a source of elements, e.g. fiber, magnesium, zinc, calcium, potassium, iron, fluorine, phosphorus and copper, as well as folic acid and omega 3 acid, vitamins A, B, C, D, E are more and more commonly used in supplements (supplements with algae are recommended for various dysfunctions, e.g. an ingredient supporting slimming) and functional food. Algae, rich in elements, are eagerly used in the production of cosmetics, because they stimulate the reconstruction and protection of the epidermis, soothe irritations, and also have anti-allergic and anti-inflammatory properties. They have a cleansing, moisturizing and soothing effect, making them suitable for the care of dehydrated, acne and hypersensitive skin. In the cosmetics industry, they are also used in the production of preparations that accelerate skin healing, regenerate and rejuvenate. Algae is also used in pharmacy and laboratories, and for the production of biomaterials. Due to their anti-inflammatory, antioxidant, antibacterial, anticancer and antioxidant properties, algae can be used in the treatment of many diseases in the world, because there is a growing interest in natural pharmaceuticals, which are perceived as safer for humans. Algae as a renewable energy source, also represent a huge potential in the production of biofuels, and the rapidly advancing technology development makes them increasingly used in other technical and industrial products. As macroalgae uptake naturally occurring nutrients, their cultivation sites may also provide environmental services - they can be used as a tool to combat eutrophication. The biogen content and the rate of their uptake vary between the macroalgae species and populations and depend on environmental conditions. Generally, growth rates and the nutrient uptake rates are higher in fast growing green macroalgae than slow-growing species like many red and brown seaweed. Based on the calculations, it is possible to remove 1.3-7.9 kg of nitrogen and 0.2-1.9 kg of phosphorus while harvesting 1 ton of Baltic macroalgae, depending on the species. The macroalgae species that, according to their properties, content of valuable substances or abundance can be considered suitable for cultivation in the Baltic Proper and adjacent basins are: (1) red alga Furcellaria lumbricalis - the only species that was harvested on a commercial scale in the Baltic Sea to obtain polysaccharide furcellaran (gelling agent); (2) red alga Ceramium tenuicorne - this small, filamentous species contain many bioactive substances, can be utilised to produce agar and is rich in red pigment phycoerythrin; (3) brown alga Fucus vesiculosus that has been used as food and medicine for centuries is commercially harvested in few countries outside the BSR to obtain its structural polysaccharide fucoidan and can be also used as a source of alginic acid; (4) Ulva intestinalis - green alga that is very abundant on rocky bottoms along the Baltic coasts is suitable for human consumption and cultivated in Japan. For the Western Baltic/ Sweden, characterised with higher salinity, two Laminariales species are suitable for cultivation - Laminaria digitata and Saccharina latissima and they are/ can be utilised as high value food products or in alginate industry. It should be emphasised that there are few different legal barriers but also opportunities for the cultivation and harvesting of macroalgae. The legal aspects can be divided to: (1) spatial conflicts and synergies with other users and maritime sectors resulting from Maritime Spatial Plans for BSR countries; (2) legal regulations directly related to the cultivation of marine organisms and resulting from the environmental law, usually connected to the necessity of obtaining few permissions from the relevant authorities; and (3) the regulations related to the usage of macroalgae as food and feed ingredients, connected mainly to the limits of harmful substances, food labeling and the introduction of novel species into the market. As Sacchcarina latissima and Laminaria digitata are experimentally and commercially cultivated in Sweden and Denmark, the cultivation techniques, based mainly on the long-line technology, dedicated for these species exist and are well described in the literature. The experience in cultivation of macroalgae in the Baltic Proper and adjacent basins is limited to few experimental initiatives. Based on the findings from these initiatives and on the scientific literature, we assumed that sufficient knowledge exists to plan at least experimental farms of Fucus vesiculosus and Ulva intestinalis in the Baltic Sea. Based on the results from FucoSan project, we propose fucus farms which rely on vegetative fragments of thalli as a ‘seeding’ material, placed in the experimental infrastructure consisting of floating baskets and cultivated throughout the year. For Ulva intestinalis we suggest the farm based on the long-line technique - using lines with planted spores, suspended shallow below the water’s surface and located in the shallow coastal zone, most preferably in areas characterised with high nutrient concentration. Due to seasonality, it is possible to cultivate U. intestinalis 5-6 months per year. Preliminary calculations show that the production of macroalgae in the south-east of the Baltic Sea: Poland, Latvia, Estonia is quite cost-intensive. Depending on the adopted input parameters, the production cost of 1 kg of fresh Ulva varies from 0.23 €/kg, with the optimistic assumption of efficiency of 87t/ha, up to 1.0 €/kg, assuming the pessimistic version of the yield of 9.8t / ha. The estimated unit cost of producing 1 kg of fresh Fucus is ca 2.34 €/kg. Starting the cultivation of seaweed in the Baltic Sea Region, from the market point of view, would be a response to the growing consumer demand for new, pro-health products of aquatic origin, also in line with the trend of reduced demand for animal products. Production in the Region would make it possible to offer a local, ultra-fresh product. From a socio-economic point of view, local cultivation of seaweed would contribute to increasing added value in the Region (replacing imported products), promoting employment (including people leaving sea fishing) and better utilizing the potential of fish processing plants. From an environmental point of view, the cultivation of seaweed, especially fast-growing seaweed (like U. intestinalis), offers a unique opportunity to reduce water eutrophication while accumulating CO2. The main problems and threats to the start of macroalgae cultivation in the main part of the Baltic Sea (except its western part) are: the inability to estimate the market absorption capacity for new species, practically absent in the food market of the Region (such as U. intestinalis); lack of proven in practice technologies for the cultivation of U. intestinalis and F. vesiculosus in Baltic conditions; legal and legislative barriers - especially for first market entrants; finally - the lack of public funding for the water-environmental services that will be provided by seaweed farms. The following report synthetically collects the available knowledge about the production possibilities and the seaweed market in the Baltic Sea Region and was carried out as part of the GRASS project - Growing Algae Sustainably in the Baltic Sea.
