Evaluation on feeding with sente leaves and enrichment on the conditioning of giant gourami (Osphronemus gouramy) broodstock

Abstract

Abstract Spawning in the aquaculture of giant gourami is an important factor which determines the success of production because it supports the sustainability and improvement of the quality and quantity of giant gourami fry in aquaculture activities. The purpose of this study was to evaluate the feeding in the conditioning of giant gourami (Osphronemus gouramy) broodstock. The methodology carried out included the preparation of spawning ponds, broodstock selection, broodstock feeding, spawning, conditioning, nest inspection and egg collection, egg handling, egg hatching, and larval rearing. The eggs produced were 21.452 eggs with 18.714 fertilized eggs and 2,738 unfertilized eggs, and the Fertilization Rate (FR) value obtained during the study was 87.3%. Eggs that successfully hatched into larvae were as many as 16.238 while eggs that did not hatch were as many as 2.341 eggs, and the Hatching Rate (HR) value obtained was 87%. The water quality data obtained from the broodstock pond and the hatching pond included DO with a range of 5.88 – 6.11 mg/L, a temperature of 27.2°C – 28.2°C, and a pH ranging from 7.21 to 7.27.
