POLA PERTUMBUHAN IKAN LAYANG (Decapterus ruselli) YANG DARATKAN DI PELABUHAN PERIKANAN LABUAN BAJO KABUPATEN DONGGALA PROVINSI SULAWESI TENGAH

Abstract

The growth pattern of flying fish (Decapterus ruselli) landed at the Labuan Bajo Fish Landing Base, Donggala Regency, has never been implemented. Based on this, research on estimating the growth pattern of flying fish (Decapterus ruselli) is necessary to support these fish resources' sustainable use. This research aimed to study the growth pattern of flying fish (Decapterus ruselli) in Labuan Bajo Fishery Port, Donggala. Flying fish were taken from the catch of fishers who landed their catch at Labuan Bajo Fishing Port, Donggala. Sampling was proportional to the stratified sampling method, namely groups of a small, medium, and large fish. Data were analyzed by a simple linear regression method using Microsoft Excel 2016. The results showed that the growth pattern of flying fish (Decapterus ruselli) landed in Labuan Bajo Fishery Port showed a tendency to be the same. The daily data showed a negative allometric growth pattern and a sigmoid (logistic model). The flying fish condition factor every day is good, where the average value is more than 1 (K> 1). The condition factor > 1 indicates that the flying fish caught around the waters of Banawa is in good condition.
