In the video, Workers at a coastal fish farm shovel fresh dead fish into circular net pens holding Protonibea diacanthus (red-mouth croaker). This species, a prized marine fish in Asia, requires high-protein feed for growth. Using locally sourced small fish as feed cuts costs by 70% versus processed pellets. Daily feeding maintains growth rates while reducing cannibalism among the fish. Such efficient practices support sustainable aquaculture in resource-limited regions.
