Abstract

Pinrang Regency is included in the scope of Indonesian waters which has the potential to catch red snapper. Snapper is an export commodity that has a high market price with a selling value of around Rp. 70,000 / kg. The aim is to determine the size structure, gonad maturity and sex ratio. This research was conducted from March to July 2019 in the waters of Pinrang Regency. The observed aspects are size structure, gonad maturity and sex ratio. The results obtained as many as 532 fishes, of which 226 males and 306 females. The total length ranges from 19.5 to 69.5 cm with the sex ratio in a balanced state. Gonadal maturity is 36% under immature conditions and 64% are mature gonads. The size of the first time maturity is 29 cm in males and 37 cm in females.

Abstract

The use of semah fish with the local name pelian fish in nature is carried out using various methods, one of which is using tuba root plant poison. This tuba root poison is thought to have an impact on the biological condition of pelian fish and aquatic ecology. In connection with this, this research aims to analyze the size distribution, growth type and food habits of pelian fish. The research was conducted from June to August 2023 in West Krayan District, Nunukan Regency, North Kalimantan. The results of the study showed that the length distribution of pelian fish caught using tuba root plant poison was 30.626 ± 7.048 cm, with a weight of 786.531 ± 430.066 g. The growth pattern is negative allometric with eating habits consisting of moss at 44.57%, insects at 33.04%, pieces of fruit at 10.00% and unidentified at 12.39%. Moss and insects are the main food, while fruit is a complementary food. Based on the results obtained, pelian fish in nature can be caught using moss bait. The use of high doses of tuba root can cause damage to the fish's gills, which can cause fish death as a result of not being able to neutralize rotenone.
