Abstract

Milkfish (Chanos chanos) is valued in aquaculture for its affordability and nutritional richness. However, conventional farming techniques frequently result in suboptimal yields due to lead (Pb) contamination. Traditional milkfish ponds are typically situated near coastal areas, river waters, estuaries, ports, and industrial zones, rendering them susceptible to contamination, particularly from heavy metals, like Pb. This study aimed to analyze Pb accumulation in the body of milkfish juvenile, identify liver and gills damage, and examine the growth rate and survival of milkfish exposed to Pb at various concentrations. Juvenile milkfish were exposed to various concentrations of PbNO3, namely 0 mL.L-1, 0.08 mL.L-1, 0.8 mL.L-1, and 8 mL.L-1, including the non-exposed control group. The metal content of the fish bodies was measured using an AA spectrophotometer. Histological analysis of the liver and gills of the fish was performed to evaluate organ damage. The results showed significant Pb accumulation has been observed in milkfish exposed to high Pb concentrations. The control treatments showed a decrease in metal content, whereas treatments with high concentrations showed a significant increase. Exposure to Pb within 30 d can cause organ damage, such as inflammatory cells, secondary lamella fusion, and necrosis that occurs in the gills. In the liver, there is damage such as the accumulation of inflammatory cells, necrosis, and hydrofic degeneration. Pb exposure rapidly damages and disrupts milkfish's biological functions, influencing survival and growth. Pb exposure with doses 8 mL.L-1 significantly affected juvenile milkfish within approximately 60 min.

Abstract

Maggot (Black Soldier Fly/BSF larvae) is a high-protein resource that can be utilized as an alternative raw material for fish feed. Maggot production has great potential to reduce dependence on commercial feed while also utilizing organic waste. This community service program aims to introduce maggot production technology to fish farmers in Soppeng Regency, South Sulawesi, by using household organic waste as feed for snakehead fish (Channa striata). The activities include counseling on organic waste sorting, maggot cultivation training, and the application of maggot as fish feed. Through this program, the community gained an understanding of how to manage waste into high-quality maggot and use it as fish feed. The results showed that the community not only understood the maggot production process but also successfully utilized it independently to reduce fish feed costs. This program successfully raised awareness about the importance of organic waste management, supported freshwater fish farming, and had a positive impact on the environment. By utilizing maggot as an alternative feed, it is hoped that the community can develop more efficient and environmentally friendly fish farming, while also creating a sustainable organic waste management model.
