摘要: Abstract:
Taiwan is known for its competence to undertake advanced mariculture activities and is acclaimed for its achievement in pioneering some aquaculture work. Nevertheless, less than half of the local species of marine finfish at present under cultivation in Taiwan have thus far been investigated for their controlled propagation. It is therefore clear that the mass propagation of most fish of economic importance to Taiwan still remains in its infancy.
During the past 17 years, systematic steps have been made to perfect fry production techniques for various marine fishes to a various extent such as the supply of spawners, induced maturation, spawning methodology, artificial fertilization, smooth hatching, larval rearing, improvement of survival rates of larvae and the completion of the life cycle of some species in captivity. The success in the artificial propagation of the grey mullet and the completion of its generation cycle in captivity, presently heads the propagation of marine finfish in Taiwan. The latest preliminary success in the propagation and completion of the life cycles of the red sea bream and black porgy are further new landmarks in this respect. The recent improvement of the traditional milkfish culture method, the great demand on the groupers for the export market, the shortages in natural fry of the mud skipper, which resulted from overfishing, and the prevailing luxury price of the Japanese sea bass, are all factors which point to an urgent need for the controlled propagation of these fish species. Fortunately work on these fish is now in the initial stages of experimental success. The propagation studies of other species, including the giant perch, thread fins, theraponids, sand borers, grey snapper, siganus etc., only recently commenced or still remains untouched.
Practical experience on the mass propagation of freshwater fish and marine prawns serves as an example to underline the bright prospect for similar efforts on marine finfish. Good progress can be expected in the future provided that more manpower can be recruited, increased effort achieved and proper guidance of research projects obtained in this very important developing science in Taiwan.
