Opis:: The occurrence of algae on the Sopot beach was investigated from 2004 to 2006 from the beach management point of view. Various methods were applied in an attempt to understand the mechanisms underlying the accumulation of algae on the shoreline. They included daily observations of the occurrence of macrophyta on the beach, absorption measurements of acetone extracts of the particulate matter in the seawater, the collection of macrophyta and phytoplankton samples for biomass and taxonomic identification, and determination of the degree of decomposition on the basis of chloropigment analyses. The results were related to the environmental conditions: meteorological data and the physicochemical parameters of the seawater. The biomass recorded on the beach consisted mainly of macroalgae and a small proportion of sea grass (Zostera marina). The phytoplankton biomass consisted mainly of dinoflagellates, diatoms, cyanobacteria, euglenoids and cryptophytes. The conclusions to be drawn from this work are that the occurrence of huge amounts of macrophyta amassing on the Sopot beach depends on the combined effect of high solar radiation in spring and summer, high-strength (velocity × frequency) south-westerly winds in May-September, followed by northerly winds, bringing the macrophyta from Puck Bay on to the Sopot beach. At the same time, their abundance along the beach varies according to the shape and height of the shore, the wind strength and the local wind-driven seawater currents. According to estimates, from 2.2–4.4 × 102 tons (dry weight) of macrophyta can be moved on to the Sopot beach in one hour. In October, strong southeasterly winds can also transport huge amounts of decomposing biomass onshore. The phytoplankton content in the total biomass is negligible, even though at low concentrations its biological activity may be considerable. The intensive phytoplankton blooms observed on the Sopot beach in summer are not always caused by cyanobacteria.

Opis:: The aim of this work was to explore the possibilities of utilising the macroalgae accumulating on the Sopot beach, a part of the Gulf of Gdańsk (Baltic Sea). During this work (2004–2006) a range of activities were undertaken: monitoring the occurrence of macroalgae, collection of plant material, taxonomic identification, laboratory analyses of contamination (metals – Cd, Pb, Ni, Zn, Cu, Cr, Hg; radionuclides – 137Cs, 40K; organic contaminants – polychlorinated biphenyls, polycyclic aromatic hydrocarbons), the stage of algal degradation and studying possible uses of the plant material collected on the beach. The most suitable way of utilising the plant material seems to be as a biofertiliser. Laboratory growth tests were carried out to assess this possible use; they were successful.

Opis:: A detailed ecological study was conducted for three years (2001–03) on a 5 km stretch of well-developed coral reef facing an industrial site in the southernmost section of the Jordanian coast of the Gulf of Aqaba, Red Sea. The degree of modification associated with the prevailing ecological factors was assessed with respect to species diversity and abundance of the major groups of the macrobenthic community: corals, bivalves, hydrozoans, echinoderms, sponges and macroalgae. Three locations of two depths each – 6 and 12 m – were selected and surveyed using the visual census point-intercept method. The actual area of the survey covered about 2250 m2. Macrobenthic communities occurring close to the industrial jetty were characterized by low diversity and the obvious dominance of soft coral (16–30% cover). In the deep transects (12 m) hard coral cover was higher than that in the shallow transects (30–55%). Correlation analyses indicated that species richness increased with increasing distance from the industrial jetty. Species richness of other macrobenthos was also higher as depth increased. The results revealed that the distribution and abundance of coral, echinoderms, hydrozoans and macroalgae were correlated with the relative importance of bottom modification within the various locations in the entire study area. However, no distinct influence of location or depth on the identities of most macrobenthic species was indicated.

Opis:: The article discusses the problem of excessive growth of one-year filamentous algae, contributing to the disturbance of ecological balance in the Puck Bay. The aim of the study is to estimate the possibility of restoring this balance through the use of macroalgae as a co-substrate for biogas and fertilizer production in the regional biological wastewater treatment plant (WWTP). Effectiveness of biogas production from aquatic plants, including free-floating filamentous algae, was examined. Tests have shown that the biogas potential of seaweed constitutes the level of 162 m3/Mg of organic dry solid substances of algae. It was estimated that using the summer intense algal growth, removing 65,000 Mg of algae, 800,000 m3 of biogas can be obtained from the area covering the inner Puck Bay. After biogas conversion, 2,320 MWh of electricity and 2,100 MWh of heat energy could be produced. Harvesting free-floating algae enables the annual removal of 100-150 Mg of phosphorus and 200-400 Mg of nitrogen from Puck Bay and, thus, reduces the level of its eutrophication. Macroalgae management at a certain stage of growth also prevents the presence of algae on beaches and contributes to the improvement of fishing conditions and boosts the tourism value of the region.
Przedstawiono problem nadmiernego przyrostu nitkowatych jednorocznych glonów, przyczyniającego się do zakłócenia równowagi ekologicznej w Zatoce Puckiej. Celem artykułu jest oszacowanie możliwości przywrócenia tej równowagi przez wykorzystanie makroglonów jako kosubstratu do produkcji biogazu w biogazowni regionalnej oczyszczalni ścieków. Zbadano efektywność produkcji biogazu z roślin wodnych, w tym z wolnopływających nitkowatych glonów morskich. Przeprowadzone badania wykazały, że potencjał biogazowy glonów morskich kształtuje się na poziomie 162 m3/Mg suchej masy organicznej alg. Oszacowano, że wykorzystując letni intensywny wzrost glonów z obszaru obejmującego Zalew Pucki, usuwając 65 000 Mg alg, można pozyskać 800 000 m3 biogazu, a po jego konwersji 2320 MWh energii elektrycznej oraz 2100 MWh energii cieplnej. Odławianie wolnopływających alg umożliwia usunięcie z wód Zatoki Puckiej 100-150 Mg fosforu i 200-400 Mg azotu rocznie, a tym samym redukcję poziomu jej eutroficzności. Zagospodarowanie makroglonów na etapie ich wzrostu przyczynia się również do poprawy warunków rybołówstwa i wzrostu walorów turystycznych regionu.

Opis:: One year qualitative and quantitative study of communities of three major taxonomic groups has been carried out at test panles placed in the upper infarlittoral zone of coastal area of Vela Luka Bay, Croatia. A list of 44 taxa was recorded. Chaetomorpha sp., Ulva sp., Fosliella farinosa, Sphacelaria cirrosa, Polysiphonia scopulorum were the most frequent dominant taxa. Among 27 algal taxa with noticeable presence only three were classified as ESG (Ecological State Groups) I. Low diversity and species richness together with massive presence of the green algae (as Ulva sp.) and negligible presence of ESG I taxa, may lead to erroneous conclusion that Vela Luka Bay is eutrophicated area. Low values of biomass and R/P (Rhodophyceae by Phaeophyceae ratio) Index together with dominance of Phaeophyta also support conclusion that there is no negative impact of nutrient enrichment on macrophyta fouling community in Vela Luka Bay.

Opis:: Variations in lipid, protein and carbohydrate contents of Enteromorpha spp. were examined over a seven-month period from April to October 1993. The samples were collected from seven sampling stations along the Gulf of Gdańsk coast. The lipid content was low and varied slightly from 3.47±1.76% of DW at Puck to 4.36±2.17% of DW at Rewa and Chałupy. The protein content varied from 9.42±4.62% of DW at Puck to 20.60±5.00% of DW at Jurata. At the remaining stations the values vary over a narrow range. The maximum protein contents were recorded at the beginning and end of the growing season. The level of carbohydrate was very high compared to that of lipid and protein and varied from 29.09±6.44% of DW at Osłonino to 39.81±11.15% of DW at Puck. Seasonal carbohydrate changes were noted at all sampling stations, the minimum occurring in spring and autumn and the maximum in summer.

Opis:: Spring development in the hydrolittoral zone was investigated at five wave-sheltered and five wave-exposed sites on four occasions from late March to late May (every third week). The number of species was higher at the sheltered locations and increased significantly over time. The difference in community structure was significant: over 95% of the Bray-Curtis dissimilarities were due to the biomass of only eleven taxa, and the total Bray-Curtis dissimilarity between exposed and sheltered sites was 75%. Macroalgae made up 70–80% of the total biomass and was dominated by filamentous species. In contrast to previous studies, macroalgal biomass was higher at the exposed sites, which may be due to the fact that this was a spring study, unlike previous studies, which were conducted during summer.

Opis:: In this study, 12 taxa from the Chlorophyta, Phaeophyta and Rhodophyta were collected from different depths at Gemlik-Karacaali and Erdek-Ormanlı. A total of 175 specimens from these divisions were used to determine Total Protein (TP), Total Soluble Carbohydrate (TSCH) and Chlorophyll a (Chl a), Chlorophyll b (Chl b), Chlorophyll c (Chl c), total carotenoid (Car) contents and Chl b/Chl a, Chl c/Chl a, Car/Chl a, Car/Chl b, Car/Chl c ratios. TP, TSCH and pigment contents varied significantly with respect to the algal taxa, stations and depth distribution. In addition, individual differences were important in all of the measured parameters. The maximum TP contents (0.94%–31.03%) were determined in some of the Rhodophyta. In some green seaweeds belonging to the genus Ulva L., the TP content was determined between 2.9%–28.1%. Lower TP contents were determined in Cystoseira barbata (Good) C. Agardh (1.1%–4.3%). In contrast to TP contents, TSCH values were very low; maximum TSCH were determined in Ulva species, as were protein contents. In conclusion, the variations in TP, TSCH and pigment in 12 taxa of macroalgae were analysed according to station, depth, and environment.

Opis:: The bioaccumulation ability of radionuclides 51Cr, 54Mn, 57Co, 60Co, 65Zn, 85Sr, 109Cd, 110mAg, 113Sn, 137Cs and 241Am in two red algae species from the southern Baltic Sea – Polysiphonia fucoides and Furcellaria lumbricalis – was determined under laboratory conditions. P. fucoides demonstrated better bioaccumulative properties towards most of the investigated radionuclides. As a result, P. fucoides can be recommended as a good bioindicator of radioactive environmental pollution. The bioaccumulation of radionuclides in F. lumbricalis was studied during an extended laboratory experiment. The initial extensive uptake of radioisotopes was followed by the rapid removal of cations; in general, concentrations tended to decrease with time. 137Cs displayed a different behaviour, its concentration in the algae increasing over time mainly due to its large ion radius; this is a factor that could be responsible for the stronger mechanical and chemical bonding of Cs+ and that could hamper the movement of ions in both directions.
