Experimental fishing is a method used with two data analyses: 1) analysis of acoustic data at sampling stations with stationery techniques; and 2) analysis of acoustic data along transects between stations. The detection results at stationery 1 showed a very low abundance of pelagic fish, distributed at layer 4 (150-200 m) at night and suspected to be a large pelagic type of tuna with a small amount. The detection results on stationery 2 and stationery 3 are relatively the same, showing a relatively higher abundance compared to stationery 1. Detection results for transects between stations 1-2, 2-3, 3-4, and 4-5 starting from Dewakang waters to east of Takarawataya waters did not detect schooling fish but only single fish. On transects between stations 5-6 very low abundance, the highest mean abundance of 0.5 fish/1000 m3 was detected at layer 4 (150-200 m). On transects between stations 6-7 the abundance was not too high, the highest mean abundance was detected at layer 3 of 10.8 fish/1000 m3. The transect between stations 7-8 is the highest abundance of all transects, the highest abundance average value detected at layer 3 is 20.3 fish/1000 m3. On transects between stations 8-9 the abundance was not too high, schooling tended to be present in all layers, and the highest mean abundance was detected at layer 4 of 1.3 fish/1000 m3.

The risk of lost fishing gears during operation is very high, both due to the bad weather and interactions with other fishing gear.

Nevertheless, there have been no mitigation activities and efforts to reduce ALDFG in the Banten Bay. This study aims to identify the global causes of lost fishing gear derived from blue swimming crab fisheries in Banten Bay. Data were collected around the Archipelagic Fishing Port (PPN) of Karangantu in May-June 2022. In-depth interviews were conducted with 28 respondents who were selected purposively and the results were analyzed descriptively.

Scientific information on Siganids fishing techniques and its ecological impact are limited.

The Siganids fishing techniques were observed during the field study. The catch of Siganids species and other fishes from various fishing gears were sampled, then identified and calculated individually. The samples of Siganids fish were also measured for its length and weight. This study showed that the fishers were used three kinds of fishing gears to target the Siganids fish, i.e., rope traps, bamboo traps, and spear gun. There were five species of Siganids caught during the research, they are: Barhead spinefoot (Siganus virgatus), Goldspotted spinefoot (S. punctatus), Streaked spinefoot (S. javus), Orange-spotted spinefoot (S. guttatus), and White-spotted spinefoot (S. canaliculatus), with the Lm value of 3.5, 22.8, 30.6, 21.2, and 20.8 cm, respectively. All catches of the Siganids exceeded the catch size limit (Lm), except for S. punctatus and S. Javus which was only 65.51% and 4.00% of the respective catches were acceptable in size. Finally, the Siganids fishing activities in the study area potentially impacted the ecological function of natural food chain balance (trophic level).

The purpose of this research is to apply EAFM indicators for analyzing surface gillnet fishing gear in Bagan Siapi-api waters, especially fish resources, fishing methods, habitats, and ecosystems. The evaluation of fishery management status was carried out using multi-criteria analysis (MCA) through the development of the composite index of each EAFM indicator. The results showed that the surface gillnet fishing gear was dominant with 1,645 tons of fish caught in 2019 by fishermen in Bagan Siapi-Api Waters. The composition of the catches was sukain fish (Eleutheronema tetradactylum), flounder fish (Pleuronectiformes), and tornfish (Bovichthyidae).

Results showed that the score was 254 with a success value of 251-300, indicating high potential and standards fulfillment. Thus, PPI Binuangeun can be transferred and upgraded to PPP (Coastal Fishery Port). The results of the AHP suggested that the central priority values for the development of PPI Binuangeun include: supply, auction, landing and marketing activities with the priority value of 0.585. Subsequently, another strategy is expanding the port area with score of 0.409.
