Abstract

The local community has caught mud crabs for years and increased fishing pressures, leading to biological structure changes. Accordingly, studying the growth pattern, condition factors, and structure of mud crab in the Sanrangang River, Takalar Regency, South Sulawesi Province is necessary. This research was conducted from June to August 2020 in the Sanrangang River, Takalar Regency, South Sulawesi Province. This study compared the efficiency and effectiveness of three types of bubu, namely folding bubu, rakkang and wheel bubu based on the experimental fishing by using tilapia as the bait. Data were analyzed by Chi-Square non-parametric test. Results showed that the catch of mud crabs for folding bubu, rakkangs, and wheel bubu was 120; 107; and 110 species. The width and weight of mud crabs’ carapace caught by each bubu were as follows: from folding bubu ranged from 34.07 to 99.02 mm (60.34 ± 15.06 mm) and 21.62 to 389.57 g (92.41 ± 75.38 g); rakkang ranged from 35.09 to 98.51 mm (66.91 ± 13.95 mm) and 21.94-297.29 g (87.86 ± 34.35 g) and wheel bubu ranged from 34.21- 98.11 mm (66.32 ± 16.83 mm) and 22.01-485.45 g (102.17 ± 79.87 g). The growth patterns of the catch from all gear were negative allometric. The condition factors of folding bubu, rakkangs, and wheel bubu ranged from 0.40631-2.3998, 0.4598-2.4553 and 0.4962-3.1098 respectively. The gear producing the highest weight and the best condition factor was wheel bubu. Keywords: Condition factor, mud crab, size structure, growth type.

Abstract

Fishing technology consists of fishing gear and auxiliary fishing gear which are implemented using various methods according to the objectives to be achieved. The application of fishing technology aims to increase the effectiveness, efficiency and productivity of fishing. One fishing technology is the use of artificial bait as an attractant to attract the attention of fish so that they can easily be caught and preyed on by pelagic fish. This service is carried out in Mamuju waters for the purpose of catching pelagic fish. The service was carried out using trolling fishing gear. The results of the service showed that the results obtained were skipjack tuna (Katsuwonus pelamis), krai tuna (Auxis thazard) and yellowfin tuna (Thunnus albacares). The largest catches were obtained from fishing ground in oceanic waters with water depths above 200 m.

Abstract

Coastal water ecosystems in general have experienced damage as a result of fishing that is not environmentally friendly. This unfriendly fishing causes the fish's feeding grounds to be damaged so that fishing activities in coastal areas need to involve fishing aids to collect fish. The fishing aids implemented are in accordance with the fishing objectives to be achieved. The implementation of fishing aids aims to attract attention and bring fish to the area where the attractor is installed, making it easier to catch. One of the fishing aids used is Biological Fish Aggregating Devices (Bio-FADs Tree) or live FADs equipped with Kappaphycus alvarezii seaweed which acts as an attractor to attract fish so they can be easily caught. This service is carried out in Mamuju waters for the purpose of catching demersal fish. The service is carried out using trap fishing equipment. The results of the service showed that the catches obtained were Pink ear emperor (Lethrinus lentjan), Redbelly yellowtail fusilier (Caesio cuning), Streaked spinefoot (Siganus javus), batik Vermiculated spinefoot (Siganus vermiculatus) and Orange-spotted spinefoot (Siganus gutattus), White-spotted spinefoot (Siganus canaliculatus), and Surf parrotfish (Scarus rivulatus). All of the catches are fish of important economic value
