Abstract

The grouper (Epinephelus sp.) is a marine fish species that is widely cultivated commercially for hatchery and grow–out purposes and shows a promising production prospect. The structure and development of fish intestines are influenced by internal and external factors, such as water quality, feed quality, and feed quantity. However, even though the protein content in the diet is relatively high, the growth performance of Epinephelus lanceolatus × Epinephelus fuscoguttatus remains low. This study aimed to determine the effect of papaya simplicia supplementation on grouper growth, specifically absolute weight gain and protein efficiency ratio. The experiment used a Completely Randomized Design with five treatments and three replications (A: papaya simplicia 5%, B: 3.75%, C: 2.5%, D: 1.25%, and E: 0% as the control). Groupers were reared in floating net cages in Pangandaran Regency, Indonesia. Supplementation of papaya simplicia at 3.75% and 5% increased the number of necrotic cells (169 and 183 cells, respectively), as well as the number of goblet cells. The addition of papaya simplicia at 5%, 3.75%, and 2.5% increased the absolute weight gain to 161.36 g, 152.19 g, and 152.09 g, respectively. Supplementation at 5% and 3.75% also increased the protein efficiency ratio to 3.18% and 3.19%, respectively.

Abstract

Nile tilapia is one of Indonesia's leading aquaculture commodities, with strong potential for development to support food security and improve community welfare. This study aimed to analyze the effect of different stocking densities and to determine the optimal density that supports the survival and growth of Nile tilapia juveniles reared in the Budikdamber system. The research method used was an experimental method with a Completely Randomized Design (CRD), consisting of five treatments and three replications. The treatments were as follows: (A) stocking density of 15 fish/70 L (control), (B) 20 fish/70 L, (C) 25 fish/70 L, (D) 30 fish/70 L, and (E) 35 fish/70 L, maintained for 40 days with a feeding rate of 3% of the total biomass. Probiotics were applied at a dose of 0.8 ml/L through the culture water to maintain good water quality. The results showed that treatment B (20 fish/70 L) produced the best outcomes in terms of growth and survival, with an average absolute length gain of 2.03 ± 0.26 cm, absolute weight gain of 8.52 ± 1.11 g, a positive allometric length-weight relationship, a survival rate of 91.7%, a specific growth rate of 1.68 ± 0.17%, a feed conversion ratio of 1.59 ± 0.24, and water quality parameters within the acceptable range based on the Indonesian National Standard (SNI).
