Abstract

The purpose of this study was to determine the reproduction of Snakehead fish (Channa striata Bloch, 1793) in the waters of the Merauke district wasur swamp. The data analysis used was the sex ratio, the level of gonad maturity, and the first size of gonad maturity. The results showed that the sex ratio of male and female snakehead fish in October and November at stations I and II tended to be balanced, while in September the sex ratio of snakehead fish at station I was balanced and at station II was not balanced. The maturity level of snakehead fish gonads at TKG III in September was around 35.48%, in October 28.57% and 15.38% in November. The size of the first time the gonads were ripe, the results showed that the first time the fish were ripe, the gonads were 190 mm long and weighing 50.3 g.

Highlights

Sneakehead fish is a type of fish that lives in the freshwater swamp waters of the Wasur village
In 2003 Makmur et al [1], Explained that in the Sumatra region the form of snakehead fish processing is the raw material for the manufacture of crackers and pempek, which are processed products typical of the Sumatra region
As for research related to the biology of Snakehead fish reproduction such as sex ratio, and size of the first maturity of Snakehead fish gonads in Wasur swamp waters have not been widely studied

Summary

Introduction

Sneakehead fish is a type of fish that lives in the freshwater swamp waters of the Wasur village. Snakehead fish is used both in fresh condition and in other processed forms. Some of these types of preparations include salted fish, shredded meat, meatballs and so on, triggering high market demand for Sneakehead fish. Study of sex and maturity level of gonads (TKG) constitutes basic knowledge of the reproductive biology of a preparation and its reproductive potential. As for research related to the biology of Snakehead fish reproduction such as sex ratio, and size of the first maturity of Snakehead fish gonads in Wasur swamp waters have not been widely studied.
