The hidden ingredient powering the global rise of factory farming and aquaculture
In short: Fish meal is a calorie-dense powder made from millions of tons of wild-caught fish. While it fuels the rapid growth of farmed fish, pigs, and poultry, its production is increasingly controversial, driving ecosystem depletion and threatening the stability of local fisheries across the globe, particularly in West Africa.
Fish meal is a commercial product derived from whole wild-caught fish, bycatch, and processing waste. The manufacturing process involves cooking, pressing, drying, and grinding the raw material into a stable powder. Because it is rich in protein and essential omega-3 fatty acids like EPA and DHA, it has become a cornerstone of modern animal nutrition. As of 2010, the majority of global production was directed toward feeding farmed fish, with significant portions also used for pigs and poultry.
The industry is marked by a fundamental tension between efficiency and sustainability. It takes four to five tons of raw fish to produce just one ton of meal, and approximately six million tons of fish are harvested annually specifically for this purpose. This high demand incentivizes the capture of species that could otherwise be consumed directly by humans. Critics, including the United Nations Food and Agriculture Organization, have raised alarms regarding the overexploitation of marine resources, noting that the industry risks pushing fisheries beyond their natural replacement rates.
Safety and quality control remain significant concerns. Unmodified fish meal is prone to spontaneous combustion due to the oxidation of its polyunsaturated fatty acids, a danger historically mitigated by adding antioxidants like ethoxyquin. Furthermore, recent research has detected plastic pollution in a wide range of fish meal products sampled from across the globe. As the demand for farmed fish continues to rise—accounting for half of global fish consumption by 2016—the industry is under pressure to innovate, leading to increased research into alternatives like soybean meal, algae, and insect-based proteins to reduce reliance on wild-caught stocks.
