Fish farmers in Laguna de Bay are facing conflict of the use of the lake which is being tapped as freshwater source for domestic use. The article documents the perspectives of some fish farmers and researchers on the development of carp aquaculture industry in the lake. According to carp farmers and researchers, the industry is profitable; however, marketing, post harvest and processing strategies remain poor. In this regard, Southeast Asian Fisheries Development Center, Aquaculture Department (SEAFDEC/AQD) should be the frontline ally of carp growers since SEAFDEC/AQD developed the technology for lake culture.

Although fish culture itself is an age-old tradition in Taiwan, it was in the 1960s that the first successes on artificial propagation were achieved, with several species of Chinese carps and tilapias. The first marine fish to be bred in captivity was the grey mullet; it was first induced to spawn in 1968. Various other species have since been added to the list of propagated marine fish. The characteristics of the marine fish hatchery industry in Taiwan are outlined, considering both the outdoor pond and indoor tank systems. Future prospects are very good; Taiwan now exports marine fish larvae and fingerlings to many of its Asian neighbours and there are some 60 marine fish species for which commercial larval production is possible.
