Abstract

Branta Pesisir Fish Landing Port is one of the main landing sites for various types of fresh fish. One of the fish species diversity found there is Priacanthus tayenus, a fish that has very high economic and ecological value. This research aimed to determine the biological aspects of Priacanthus tayenus, including the length-weight relationship, sex ratio, and the gonad maturity level (GML). This study was conducted in November 2024. The sampling method used was random sampling. The results of the study on 200 Priacanthus tayenus (102 females and 98 males) showed that the growth pattern of the fish is negative allometric, with the equation W = 0.94L 1.59. The sex ratio of Priacanthus tayenus during the research period, based on the Chi-Square test, was 1:1.1. The gonad maturity level (GML) of Priacanthus tayenus was dominated by Stage II (61%) and the lowest was Stage IV (7%), indicating that the captured fish were mostly immature.
