Small Forage Fish Species
Worth 20 Percent of Global Fisheries
The world’s forage fish species — small, schooling fish such as herring and sardines that play a key role in the food web in marine ecosystems — represent about 20 percent of the global values of all marine fisheries
, according to a new study. In a comprehensive analysis of dozens of food web models from around the planet, scientists from the State University of New York at Stony Brook calculated that these small fish contribute $16.9 billion to global fisheries each year, either as direct catch or as food for larger fish. According to their findings, the direct catch value for forage fish worldwide is $5.6 billion — with the largest market being the Peruvian anchoveta fishery — while the value of fisheries depending on these small fish is about $11.3 billion. “In addition to their value to commercial fishing and other industries that depend on them for their products, forage fish play valuable roles in global ecosystems while they are still in the water,” said Ellen K. Pikitch, co-lead author of the study, published in the journal Fish and Fisheries
