The deep scattering layer micronektonic fish faunas of the Atlantic mesopelagic ecoregions
Three hundred and twenty-nine species of micronektonic fishes were identified in 1040 midwater trawl collections taken between 1963 and 1974 from the North and South Atlantic, the Mediterranean, the Caribbean and the Gulf of Mexico. The target of most tows was the deep scattering layer, and conseque...
