Opis:: This study aims to assess the quality of lagoon water used as a dumping ground for shrimp farming waste. The research uses the descriptive method. The research was conducted at the Shrimp Cultivation Site in the Banaran Kulon Progo Village, Special Region of Yogyakarta, Indonesia. The research focuses on physicochemical parameters, including temperature, pH, total suspended solid (TSS), dissolved oxygen (DO), ammonium (NH4-N), nitrate (NO3-N), and phosphate. The sampling technique is based on SNI 6989.57:2008. Sampling was carried out 48 times in 3 lagoons during rainy and dry seasons. Dialysis data was descriptively classified with the help of Storage and Retrieval of Water Quality Data System (STORET) and water quality was generally classified as C (moderately polluted) and D (heavily polluted) categories in dry and rainy seasons. The results showed that in the rainy season the highest pH, nitrate and phosphate levels of 8.3, and 6.1 and 20.8 mg∙dm-3, were up to 15% less than in the dry season in the same point. Thus, it can be concluded that these values from the STORET in the dry season are larger than those in the rainy season. The study results are expected to become a basis for the evaluation of the quality of shrimp farming wastewater so that environmental health can be controlled and the risk of waste pollution reduced.

Opis:: Shrimp activity is associated with the impact of bacterial communities. Therefore, this research aimed to evaluate the influence of the bacterial microbiota on the organic matter content of the soil of the shrimp lagoon in La Segua-Ecuador. Starting from a descriptive approach, the field research method and documentary review were used. In total, 25 soil samples were collected in 5 quadrants of 100 m2. The bacterial DNA was extracted by using the Powersoil® kit and the identification of the strains was carried out with the 16SrDNA gene. The organic matter content was determined by Walkley-Black titration. The genus Bacillus was predominant in the bacterial strains; moreover, individuals of the genera Exiguobacterium, Acinetobacter, Prolinoborus, Arthrobacter Planococcus were identified with more than 99% homology for all cases. It was concluded that the organic matter content is suitable for shrimp farming.

Tytuł:: Effect of land-use changes resulting from shrimp farming on acid sulfate soils in the Can Gio coastal wetland area (Vietnam)

Opis:: Acid sulfate soils in coastal wetland areas are particularly vulnerable to land-use changes. We identifid the potential impacts of land-use changes in the Can Gio coastal wetland area in Vietnam due to the reclamation of acid sulfate soils from shrimp farms. Our study applied the support of vector machine algorithm in ENVI software to observe land-use changes from 1995 to 2015, using Landsat Thematic Mapper and Operational Land Imager data. We classifid the land use of the study area into four major classes including vegetation, bare land, dedicated land and aquaculture land. Our study successfully met the overall classifiation accuracy requirement above 95% and kappa statistics above 0.95. Between 1995 and 2006, about 2,938.05 ha of bare land and 1,464.66 ha of vegetation (mangrove forest) were converted to aquaculture land. In contrast, between 2006 and 2015, 2,423.88 ha of aquaculture land converted back to bare land, mainly related to the abandonment of shrimp ponds due to crop failure and disease. The disturbance of acid sulfate soils through initial soil reclamation and subsequent fallowing is considered a key reason for hastening and extending soil acidifiation in the study area. We collected 144 topsoil samples from 17 fallowed ponds in two batches, and 142 of these were acidic: 128 samples were extremely and strongly acidic (pH < 5.5), 14 samples were moderately and slightly acid (pH between 5.5 and 6.5), and only two samples were neutral (pH over 6.5).

Tytuł:: Comparison Environmental Conditions and Economic Efficiency Between Organic and Non-Organic Integrated Mangrove – Shrimp Farming Systems in Ca Mau Province, Vietnam

Opis:: Mangrove forest protection is an essential solution for mitigating the impacts of natural disasters in coastal zones and climate change. Integrated mangrove-shrimp farming (IMSF) system has been promoted as a sustainable livelihood that can provide income for farmers and protect mangrove forests. However, the productivity of shrimp is limited. Therefore, to enhance the revenue for farmers, improving the value of shrimp products is a good option. Organic shrimp farming practices following the EU aquaculture organic standards have been previously applied in some areas of the Mekong delta. This study was conducted to compare technical, financial characteristics and environmental parameters between the applied (i.e., organic farms) and non-applied (i.e., non-organic farms) standards of Naturland, aiming to support the development of ecological shrimp farming and contribute towards green development. The study was carried out in Nhung Mien mangrove forest, Ngoc Hien district, Ca Mau province, Vietnam. Fifty organic farms and 50 non-organic farms were directly interviewed using structured questionnaires. And then, three farms in each system were selected for monitoring water quality. Results showed that the average mangrove coverage was 54.1% in the organic IMSF system and significantly different from the non-organic IMSF system (p<0.05). Total shrimp yield, total income and total profits tended to increase in organic IMSF system and the selling shrimp price increased by 10% compared to the conventional price. The study showed that following organic farming methods could provide higher income for farmers and a better chance to mitigate natural disasters and climate change impacts.

Opis:: Indonesia is an archipelago with a coastline of about 81,000 km and has enormous cultivation potential. The area that's the potential for aquaculture is estimated at 15.59 million hectares, consisting of 2.23 million hectares of freshwater cultivation land, 1.22 million hectares of cultivated land in brackish waters, and 12.14 million hectares of marine areas. Nowadays, only 10.1% freshwater, 40% of brackish water, and 0.01% of the marine area potentially suitable for cultivation are being used. However, land use for shrimp farming until 2017 has only reached 20% of the total potential. It is still very open to developing land for the extensification of shrimp farming. Shrimp is one of the non-oil and gas export commodities that play a crucial role. Besides the high price, shrimp also has a large market in various countries. Although the industry suffered disease outbreaks and environmental problems, Vannamei shrimp farming has recently seen a rapid expansion in Indonesia due to superior varieties and disease resistant shrimp. Vannamei shrimp is a new variety that’s some advantages, including more resistance or resistance to disease and low environmental quality, high stocking density, shorter rearing time, which is around 90-100 days per cycle. This study provides some necessary background for Vannamei shrimp farming in Indonesia. It focuses on the operating characteristics of shrimp farming in brief. Emphasis is placed on the impact of shrimp farming on the environment. Promising strategies for reducing nutrient release from shrimp farming are analyzed. Effective management measures to resolve or mitigate the adverse environmental effect of shrimp farming development have now become necessary and urgent. The sustainability of shrimp farming depends on many factors including the completeness of policies and regulations, good ecology, superior breeding and various kinds of cultivation technology and government support, advances in technology digitization and cooperation between industries shrimp farming.
