Pengkajian Stok Ikan Selar Como (Atule mate) yang Didaratkan di Tempat Pendaratan Ikan (TPI) Pantai Labu Deli Serdang Sumatera Utara

Abstract

One of the catch results at the TPI Pantai Labu is the Como Scad. The objective of this research was to determine the growth, exploitation rate, and reproduction of Como Scad (A. mate) at the Pantai Labu TPI in Deli Serdang, North Sumatra. The study was conducted from September to November 2022. The observed Como Scad had a length distribution ranging from 130 ‒ 308 mm. The growth pattern of the Como Scad during the study was positively allometric, and based on the condition factor values, both male and female Como Scad were considered thin. The sex ratio of Como Scad in September and October was unbalanced, while in November, it was balanced. The first captured lengths of male and female Como Scad were 190.26 mm and 181.97 mm, respectively. The first maturation size (Lm) for male and female Como Scad was 166.34 mm and 127.70 mm, respectively. The exploitation rate of Como Scad was determined to be 0.60, indicating recruitment overfishing and excessive catch
