The fisheries biology of flying fishes (Families: Exocoetidae and Hemiramphidae) from the Camotes Sea, Central Philippines

The catches of a small artisanal fishery for flying fishes (Families Exocoetidae and Hemiramphidae) on the Danajon Bank in the Camotes Sea. Central Visayas, were recorded during a 14-month period between 1987–1988. Catches were made using floating drive-in-nets deployed from small motorized canoes. Three species, Cheilopogon nigricans, Cypselurus opisthopus and Oxyporhamphus convexus , formed about 90% of landings. Growth, mortality and related parameters for the three dominant species in the catch were estimated from length-frequency data. Seasonal variations in catch rate and recruitment are described and thought to be linked to the two monsoon periods in the Philippines. Total mortality rates were very high and, while these may be the result of migratory movements rather than attrition, they are a cause for concern in such a highly selective fishery.
