Abstract

Threadfin bream is a demersal fish that is intensively used by the community because it has high economic value. thereby encouraging increased fishing efforts both in open waters and in areas where fish apartments are installed. Therefore, there is a need for studies of Threadfin bream caught in fish apartments as an effort to maintain their survival. This research aims to analyze the size distribution, length-weight relationship, and condition factors of threadfin bream caught in fish apartments. The research is classified as a survey type with data sources from fishermen's catches carried out in three fish apartments that have been installed for six years in Kire Budong-Budong Village, Central Mamuju Regency. The research results showed that the number of threadfin bream that were observed was 205 fish with a distribution of 46 fish in the first apartment, 67 fish in the second apartment and 92 fish in the third apartment. The length and weight of threadfin bream caught in each apartment were 20.28 ± 2.74 cm and 120.66 ± 37.84 g for the first apartment, 20.16 ± 3.24 cm and 121.52 ± 48, respectively. 44 for the second apartment 20.13 ± 3.15 cm and 120.74 ± 45.85 g for the third apartment. Meanwhile, the growth pattern of threadfin bream for the three fish apartments was negative allometric and the condition factor value ranges from 0.8872 to 1.145.Keywords: Central Mamuju; Condition Factor; Fish Apartment; Growth; Size Distribution; Threadfin Bream

Abstract

Squid is one of the marine fishery commodities that is widely used by the public, causing increasing demand. This research aims to determine the composition and size distribution of squid catches based on attractor color. The research used three attractor colors, namely white, black and blue and operated in the waters of the Makassar Strait for 12 trips on a squid fishing boat using hand lines. The results of the research showed that the catch was 149 individuals with a composition of 16.11% caught on white attractors, 32.21% caught on black attractors and 51.68% caught on blue attractors. Weight distribution of squid using white attractor ranges from 10-55 g (29.75 ± 12.86 g), tentacle length 6-15.3 cm (8.94 ± 2.35 cm), black attractor 15-99 g (36.58 ± 17.63 g) tentacle length 7.5-20 cm (10.33 ± 2.34 cm) and blue attractor 15-95 g (46.62 ± 21.93 g) tentacle length 7-19 .2 cm (11.39 ± 2.84 cm). The composition of the catch, the distribution of mantle length and the largest weight were obtained from the blue attractor.
