Abstract Indonesia has fishery commodities favoured by the world market, especially blue swimming crab fisheries. Fishing activities that continue to increase have caused the blue swimming crab population in nature tend to decrease. Therefore, it is necessary to develop aquaculture in ponds and coastal waters. However, blue swimming crab enlargement has technological constraints that have yet to be widely known by the wider community. The study aimed to determine the survival rate of blue swimming crabs in coastal waters using ponds conducted in Pamekasan, East Java. The parameters measured we

The purpose of this study is to determine the management of blue swimming crab habitat through mapping potential areas offshore ecosystems in the waters of Labu Beach, North Sumatra, knowing the supporting factors for blue swimming crab habitat in the waters of Labu Beach, North Sumatra, and d

One of the leading fishery commodities with important economic value is the blue swimming crab (Portunus pelagicus). The product that has a promising market share from this commodity is processed blue swimming crab in the form of cans or airtight packaging which has the HS code 160510. The problem is that the export market share of Indonesian processed crab is limited to certain countries (the United States), while other market shares have not been developed. This study aims to: (i) analyze the competitiveness of Indonesian processed blue swimming crab in the international market, (ii) determi

The fisheries have been monitored by the Indonesian Blue Swimming Crab Association (APRI) by deploying enumerators who collect some data on the volume and size of crabs captured by fishermen. Information on the economic aspect of the fisheries, i.e., the business feasibility, has not been studied. The method in this study is observation and interviews. Based on monitoring data for 5 fishing units, the financial performance of the crab fisheries was evaluated.

The results indicate that the airflow rates lead to a reduction in evaporation rates by 6.39% and 4.53%, respectively, without significantly affecting salinity levels.
