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.

Opis:
Objective: To evaluate the immunostimulant (ISt) role of Mucuna pruriens-seed (Mp-seed) enriched with Artemia (Ar) in Litopenaeus vannamei (L. vannamei) infected by Vibrio harveyi (V. harveyi). Method: Fifteen shrimp (30±5g) were stocked per 250 L tank in 3 replicates and fed twice daily with Ar enriched with Mp-seed methanolic extracts at 100 ppm and 200 ppm for 21 days. Infected L. vannamei shows altered immunoparameter (IPM) and antioxidant enzyme status due to the V. harveyi infection induced stress. Results: Significantly increased (p<0.05) total haemocyte count, respiratory burst, phenoloxidase and superoxide dismutase activities were observed in shrimp fed with Mp enriched Ar diets compared to infected group. Supplementation of Mp enriched Ar in diet could enhance the immunity of shrimp against V. harveyi infection by reverses the antioxidant level. The histology of hepatopancreas (HPC) also shows Mp-fed groups has restores the normal structure. Conclusion: The study demonstrated that Mp enriched Ar in diet have a potentially role in ISt and an effective antioxidant by regulating infectious stress against vibriosis.

Opis:
Whiteleg shrimp (Litopenaeus vannamei) farming is a major activity in the coastal areas of many tropical countries. To meet the demand in this market, the culture system has expanded using intensive technology, which has resulted in the emission of effluents that threaten the surrounding aquatic ecosystem. Therefore, proper aquaculture management is needed to ensure both economic and ecological benefits. This led to the emergence of eco-green aquaculture. Water quality monitoring is a critical part of aquaculture management and when performed regularly, it yields a large and complex dataset. In this study, the authors aimed to analyse the dynamics of water quality characteristics and the relationships between these variables in whiteleg shrimp ponds in a tropical eco-green aquaculture system from 2020 to 2022. Since the data includes nine parameters and is quite complex, the principal component analysis (PCA) approach was used. This method enables to identify the factors that determine water quality, which will help ensure effective and efficient aquaculture management. Consequently, the water quality variables in the studied area were reduced to five dimensions and salinity, ammonia, and pH were found to be the key factors responsible for the changes in water quality characteristics. Hence, these variables should be the focus of farming management systems.
