Temporal Catch Composition and Length-Weight Relationship of Glass eel (anguilla sp.) Caught in Konaweha River Southeast Sulawesi Indonesia
Abstract
This study aims to identify the type of glass eel in the Konaweha River estuary, determine the number of glass eel catches in the dark and bright moon phases, determine the growth pattern and condition factors of the glass eel in the Konaweha River estuary, Konawe Regency, Southeast Sulawesi. The research was carried out in July 2020-July 2021. The collection of glass eel data was carried out through catching using a modified bagged net fishing gear to catch glass eel. The results of identification and calculation of morphological characters found 2 types of glass eel, namely Anguilla bicolor pacifica (58.88%) and Anguilla marmorata (41.12%). The catch in the dark month (90.82%) was higher than the light month (9.18%). The growth of glass eel was negative allometric (0.4586-2.6120) and condition factor value (0.580-2.057).
