Abstract

Vibrio parahaemolyticus is one of the pathogens in crustaceans that can cause mass death in vannamei shrimp farming. This study aimed to evaluate the effect of administering the commercial herbal supplement Phycurma Aquatic (PA) through feeding at different doses to prevent V. parahaemolyticus infection in vannamei shrimp. This study used a completely randomized design (CRD) consisting of five treatments and three replications, which are negative control group, positive control group, and PA at doses of 2.5, 5.0, and 7.5 mL kg-1 feed. Shrimps were reared for 30 days and fed five times a day. On the 31th day, shrimps were challenged with V. parahaemolyticus at a dose of 105 CFU mL-1, except for the negative control group. The results showed that the administration of 5.0 mL kg-1 of PA in the feed gave the best growth performance (P<0.05) compared to other treatments. The administration of 5.0 mL kg-1 PA in feed also enhanced shrimp health status and significantly increased the total hemocyte count, phagocytic activity, respiratory burst, and phenoloxidase. Furthermore, the administration of PA also increased antioxidant activity, reduced malondialdehyde levels, decreased V. parahaemolyticus population in the intestine, and reduced hepatopancreas tissue damage. Moreover, the survival rate of vannamei shrimp before and after the challenge test in the treatment group with a dose of 5.0 mL kg-1 of PA was significantly higher (P<0.05) compared to other treatments.

Abstract

The blue panchax (Aplocheilus panchax) is a freshwater fish species that inhabits river and swamp waters. This fish is known for its ability to survive under various changes in water quality conditions. This study aimed to explain the length–weight relationship, condition factor, and conservation status of the blue panchax in Way Betung, South OKU Regency. The research method used was direct observation with purposive sampling techniques. Sampling was conducted from April to May 2026. A total of 29 fish samples caught using traditional fishing gear were analyzed at the Kolam Percobaan Laboratory, Aquaculture Study Program, Universitas Sriwijaya. The results showed that the growth pattern of the blue panchax was negatively allometric, with the regression equation W = 2.437L²·⁷⁴ (R² = 0.9645). The condition factor obtained was 1.0068 ± 9.8105, indicating that the fish population in the wild is still in good condition.
