PLAGIASI: Optimization of Tilapia Fish (Oreochromis niloticus) Eggs Hatchability with a Funnel System

Abstract

Efforts to increase tilapia fish yields to obtain productive seeds cannot be separated from regular care and monitoring starting from the spawning process, hatching of fish eggs, and rearing of larvae until they become fish seeds. The hatching funnel is a technique for naturally hatching eggs. The research aims to analyze the hatchability of tilapia eggs in a funnel system. The research will begin in August - December 2023, which will be carried out in Beringin Village of South Kalimantan. The treatment design in this study with variations in tilapia egg stocking density in the hatching process using a funnel system, can be seen as follows: Treatment A: Stocking density 100 eggs/volume, Treatment B: Stocking density 125 eggs/volume, Treatment C: Egg density 150 grain/volume. The best value was obtained for the effect on egg hatchability in the funnel system in treatment A (33.33%) followed by treatment B (9.60%) and the lowest in treatment C (6.67%).
