The multi-species Philippine tuna purse seine fishery targets three tuna species: skipjack (Katsuwonus pelamis), yellowfin tuna (Thunnus albacares) and bigeye tuna (Thunnus obesus). These are highly migratory pelagic fishes that grow to different maximum lengths and weights. At present there is no mesh size regulation specific to the fishery in the Philippines although tuna purse seines generally use 8.9cm (3.5 in) mesh size in the bunt of the net. An empirical analysis was conducted to compare the catches of purse seine nets with two different mesh sizes in the top portion of the bunt: 8.9cm and 12.7cm. Field measurements of …

The development of aquaculture in the Agno-Pantal-Calmay River Estuary system of Dagupan City, Pangasinan Province in the Philippines is reviewed. Traditionally, extensive pond culture of milkfish, Chanos chanos and penaeid shrimp was practiced along with culture of mangrove oysters, Crassostrea iredalei, in adjacent estuarine waterways. Netpen culture of serranid groupers in the estuaries began in the early 1980s, followed by intensive fish pen culture of milkfish in the late 1980s. Over intensification of finfish aquaculture led to hyper eutrophication and fish kills beginning in 1996. Official governmental response to the fish kills is reported, and recommendations to prevent future fish …
