The small pelagic fishery of the Pemba Channel, Tanzania: What we know and what we need to know for management under climate change
Small pelagic fish, including anchovies, sardines and sardinellas, mackerels, capelin, hilsa, sprats and herrings, are distributed widely, from the tropics to the far north Atlantic Ocean and to the southern oceans off Chile and South Africa. They are most abundant in the highly productive major eas...
