Abstract

Tilapia (Oreochromis niloticus) has great potential in aquaculture due to its fast growth and delicious meat. However, challenges in providing quality feed and low nutrient intake hamper production. Administration of starfruit extract, rich in vitamin C and antibacterial compounds, can improve feed quality and support fish growth. Research shows that the addition of this extract can increase the weight, length, and survival of tilapia. Thus, using starfruit as a feed supplement at UPR Sumber Rezeki, Palembang, is expected to increase tilapia aquaculture productivity. Tilapia maintenance was carried out for 30 days, using 2 nets in a tarpaulin pond. The first net (P0) is for tilapia maintenance without the addition of starfruit extract, while the second net is for tilapia maintenance with the addition of starfruit extract (P1). Tilapia maintenance with periodic fasting for 30 days resulted in absolute length growth of 3.60 cm, absolute weight growth of 14.30 g, and 100% survival. The results of tilapia maintenance are classified as good compared to maintenance without the addition of starfruit extract.

Abstract

Intensive brackish water whiteleg shrimp (Litopenaeus vananmei) cultivation has seen increasing production. This analysis study aimed to analyze the main diseases that attack whiteleg shrimp (Litopenaeus vananmei) intensively in Takalar Regency, South Sulawesi, and the distribution patterns of these diseases. The research method used a qualitative descriptive approach with data collection through literature studies, surveys, interviews, field observations, and laboratory studies. The study results indicated that the diseases intensively attack whiteleg shrimp in Takalar Regency were White Spot Syndrome Virus (WSSV), Enterocytozoon hepatopenaei (EHP), and Acute Hepatopancreatic Necrosis Disease (AHPND). The pattern of disease attacks occured more frequently during the transition season or the change from the dry season to the rainy season in Takalar Regency. This pattern of attacks occured when there is a drastic change in temperature that affects water quality parameters sucIh as pH, salinity, alkalinity, and ammonia levels. The spread of these shrimp diseases is transmitted horizontally in a cluster pattern. The results of the analysis and identification of these disease attacks are expected to be a reference for disease control strategies
