TOKYO -- Japanese researchers have drawn closer to developing a plant-based fish food that will reduce the need for hatcheries to rely on processing other fish for fodder, and help conserve Japan's dwindling marine population.
A team at Tokyo University of Marine Science and Technology, or Tumsat, recently hit upon fish feed derived from soybeans and invertebrates. Fish farms usually use fodder made from smaller fish since they contain the proteins and lipids necessary for growth.
