Muarareja Fishermen Perceptions on The Prohibition of Arad and Environmentally Friendly Fishing Tool Assistance Programs

Arad has been prohibited because of its damages to the environment. However, fishers in Muarareja continue to operate the gear even though environmentally friendly fishing gear (traps) have been granted as a substitution. The reason behind the rejection of substitute fishing gear is interesting to be investigated. Therefore, the study aim to 1) analyze fishers' perceptions of arad prohibition, traps, and environmentally friendly fishing gear program; 2) evaluate fishers' perception on policies concerning arad prohibition and fishing gear substitution; and 3) formulate the recommendations. This study involved 35 arad fishers in Muarareja Village who has been granted with traps as substitute fishing gear. Variables in this study are fishers' perceptions on arad and trap, the policy of arad prohibition, and fishers' perception on the environmentally friendly fishing gear program. Data were collected through interviews and questionnaires. Data were analyzed by scoring respondents' answers based on provided statements. The results showed that fishers did not agree that arad is not environmentally friendly, while the trap is. Fishers are also against arad prohibition and refuse to use traps as a replacement. Furthermore, fishers who received traps are still very dependent on arad and use traps only for alternative fishing gear. Recommendations for the policy of arad prohibition are arad should be allowed with special regulation, and further education is required for fishers to understand the correlation between unselective fishing gear and environmental damages. Recommendations for the environmentally friendly fishing gear program are that the provision of traps should be continued with several adjustments following fishermen's preferences.Keywords: Prohibition of arad, environmentally-friendly fishing gear, traps.

PENGEMBANGAN DESAIN PINTU MASUK BUBU LIPAT BERDASARKAN ASPEK TINGKAH LAKU RAJUNGAN

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.
