Regulations that require changing feed formulations to exclude fishmeal would extend the tipping point for the forage fishery to 2050. Also, the common practice of adding fishmeal to pig and poultry feed is unnecessary. Non-carnivorous and freshwater fish, like carp, do not need Omega-3 in their diet. Policy intervention is needed to halt the overharvesting of oceans for fish feed and to incentivize two existing sustainable options.įirst, aquaculture farmers in China and beyond need to stop feeding fishmeal and oils to animals that do not need it. Researchers now estimate the demand for forage fish will exceed the ocean’s supply, hitting the tipping point by 2037. However, balancing the growing demand for seafood within the sustainable ecological limits of forage fish production is a big challenge. Small forage fish like sardines, anchovies, and herring are natural fish food, supplying all of the necessary nutrients for valuable and delicious, carnivorous aquaculture species like salmon.

When little fish and crustaceans eat these plants, and then are consumed by bigger fish, Omega-3 concentrations increase. The current rate of harvesting ocean forage fish to feed farmed fish, like salmon, trout, and bass, is not sustainable, and may lead to the collapse of the forage fishery.Īt the base of the food chain, algal plants make small amounts of Omega-3. Thus, feeding wild small ocean fish to farmed fish does not solve the problem of not enough fish in the sea. Aquaculture currently uses 75 percent of global fish oil supplies.įrom whales to sea birds, small fish are an important food source and the foundation of the marine ecosystem. Annually, about 19 million tons of wild fish are processed globally into fishmeal and fish oil. Fishing fleets around the world harvest small, forage fish (also called “bait fish”) from the ocean to make fishmeal and fish oil that is high in Omega-3 that goes into fish food. However, in China, the United States, and elsewhere, feeding all the fish grown in aquaculture remains a challenge. The growth in China’s aquaculture is filling in the gap between high demand for fish and the leveling off of catches of wild fish. Fish, like people, cannot make Omega-3, so they too get it from their food.Ĭhina has the largest aquacultural production in the world, growing fish and other seafood in ponds and tanks. Omega-3 is an essential fat, but our bodies cannot make it, so it must come from the food we eat, and fish is the best source. ![]() They were right-the Omega-3 fatty acids in fish are good for our health. This is a lesson we learned from our mothers and grandmothers.
