Abstract

Ponyfish (Leiognathus equula) is one of the demersal fish that is widely caught in the coastal waters of Cilincing and has quite significant value because it is consumed by most of the Cilincing community both in fresh and dried form. This study aims to analyze the reproductive aspects of the fish. Sample data collected include total length, weight, and reproductive aspects. This research was conducted in March-July 2023. Fish samples were collected using gill net (mesh size 1-2 inches). The results obtained a total of 150 ponyfish (52 males and 98 females), the length-weight relationship of the fish was W = 0.1682L^2.0979 (males) and W = 0.0169L^2.9941 (females). The gonad maturity of female ponyfish spread from maturing to mature gonads, and gonad maturity stage of male ponyfish spread from immature to mature gonads. Based on gonad maturity and gonad somatic index, spawning occured around June and July. Fecundity of ponyfish ranged 108,287-362,667 oocytes. Oocytes diameter ranged 0.18-0.514 mm, based on the distribution of oocytes, ponyfish is thought to have a total spawner type.
