Abstract

Highly nutritious insects, such as black soldier fly (BSF) larvae, also referred toas maggot, have been evaluated as feed in monoculture systems, but their use in multi-trophic systems has not been previously investigated. This study used maggot-based feed in a multi-trophic system on a laboratory scale to evaluate the survival and growth performance of tilapia (Oreochromis niloticus). Tilapia were cocultured with freshwater lobster, freshwater clams, and paddy. Four experimental diets were used including a commercial pellet as a control (CP), live maggots (LM), dried maggots (DM), and supplemented maggots (SM). Tilapia (initial weight, 4.1 ± 0.2 g) and other organisms were reared in plastic tanks (water volume 50 L) and randomly distributed into 12 tanks, each containing 20 individual tilapia. The experimental diets were given four times a day at a feeding rate of 10% tilapia biomass. After 28 days of feeding, the survival and growth of tilapia on the CP diet were 90.0% and 2.8% day-1, LM 93.3% and 2.7% day-1, DM 93.3% and 3.3% day-1, and SM 90.0% and 3.1% day-1, respectively. There was no significant effect (P > 0.05) on the survival performance among the experimental diets. However, the growth confirmed by Specific Growth Rate (SGR) showed a significant effect (P < 0.05). SGR values were found to be significantly higher in the DM and SM diets than in the CP diet. An important finding of this research is the potential of maggot-based feed to increase the growth of tilapia in multi-trophic systems without impairing their survival.

Abstract

The primary challenge encountered in the production of tilapia is a bacterial disease that is induced by the bacterium Aeromonas hydrophila. Crop failure and the mortality of cultured animals are among the consequences. Certain herbal plants contain antioxidants that can exert a therapeutic effect against the A. hydrophila bacterium. The objective of this investigation is to ascertain the survival of fish following infection with A. hydrophila bacteria and their behavior and morphology prior to and following immersion in purple sweet potato leaf extract (Ipomoea batatas). In the initial stage, the survival rate was assessed through the challenge test with A. hydrophila 108 bacteria. The second stage involved the observation of the behavior and morphology before and after immersion in purple sweet potato leaf extract (I. batatas). This research was conducted in two phases. The treatment concentrations were as follows: treatment A (without extract / 0 mg/L), treatment B (40 mg/L), treatment C (60 mg/L), and treatment D (80 mg/L). In the research, abnormal behavioral changes, including the presence of red sores on the tail and a decline of appetite, were observed. The fish maintained an appetite, exhibited normal body movements, and swam actively when treated with D. Conversely, treatment A demonstrated a subpar response until the conclusion of the observation period. The effective inhibition of mortality in Nile tilapia was demonstrated by the survival rate of Nile tilapia larvae infected with A. hydrophila bacteria after treatment with a solution of purple sweet potato leaf extract (I. batatas) for 24 hours. The survival rate was observed over a 7-day period.
