Abstract

Blue swimming crab fishing using collapsible traps is widely used by fishermen because its caught live crabs and high selectivity. However, the passive fishing operation causes its low fishing productivity. The success of crabs fishing using folding traps is influenced by the suitability of the entrance design used. The size of the net and the inclination angle that are not by the crab's behavior will cause the crab to fail to be caught. This study aims to determine the more effective entrance design for catching crabs using the collapsible trap. The study was conducted in a laboratory using three mesh sizes, including 1.00, 1.25, and 1.50 inches with 30°, 40°, and 50° inclination angles. Each treatment combination uses different individual crabs. The study was conducted at night in an aquarium equipped with an infrared camera. Differences in mesh size and angle of inclination affect the crab's success rate and crawling speed in crossing the net field. The results showed that the highest percentage of crabs that successfully crossed the net field was obtained using a 1.25-inch mesh with an angle of 40°. The highest average crawling speed was also obtained at the same mesh size and angle of inclination. The use of a 1.25-inch mesh with an angle of 40° is expected to increase the effectiveness of catching crabs with folding traps.

Abstract

The functions and benefits of the existence of the mangrove ecosystem are strongly influenced by their health conditions. Ideally, a healthy mangrove ecosystem will provide greater ecological, economic, and service benefits. This study aims to determine the health condition of the mangrove ecosystem as a first step for disaster mitigation and productive economic development in the coastal area of the Sunda Strait. Data collection was carried out in November-December 2021 using the MonMang application in five different villages. The results showed that the highest diversity of mangrove species was found in Cigorondong Village with 9 species including Acanthus ilicifolius, Avicennia marina, Aegiceras corniculatum, Derris trifoliata, Sonneratia caseolaris, Excoecaria agallocha, Lumnitzera racemosa, Ceriops tagal, Heritiera littoralis. The highest canopy cover (79%) was found in the mangrove ecosystem in Citeureup Village and the highest tree density was found in Cigorondong Village at 3,300 individuals/ha. The health condition of the mangrove ecosystem on the coast of the Sunda Strait is moderate because the MHI value obtained is in the range of 33-63%.
