Abstract¡G
The principal objectives of this research are to investigate the species composition and distribution of larval fish in relation to water temperature¡Bsalinity¡Bchlorophyll a and the abundance of copepods in Tapeng Bay and Kaoping coastal waters.
Thirty-one species of the larval fish belonging to 29 genera and 16 families were identified in Tapeng Bay, with the mean numerical abundance of 22.9 ¡Ó40.7 ind./100m3 during the sampling period between June 1999 and December 2001. The trend of seasonal change in numerical abundance of the larval fish was not coincident interannually. The 7 most dominant species were Omobranchus sp., Tridentiger obscurus, Pterogobius Zonoleucus, Blenniidae gen. sp., Gobiidae gen. sp., Entomacrodus lighti and Engraulis japonicus, occupied 94% of the total larval fish abundance¡Famong these, the first two dominant species, Omobranchus sp. and T. obscurus contributed to 80% of the total count.
One hundrad and eighty-four species of the larval fish belonging to 130 genera and 69 families were identified in Kaoping coastal waters, with the mean numerical abundance of 390.6¡Ó593.5 ind./100m3 during the sampling period between June 1999 and June 2001. Generally, the numerical abundance of the larval fish showed significantly seasonal changes, with lowest in winter and up to highest value in summer. The 10 most dominant species were Sillago japonica, Engraulis japonicus, Tridentiger obscurus, Gobiidae gen. spp., Pagrus major, Scomberoides lysan, Leiognathus nuchalis, Ceratoscopelus warmingi, Scatophagus argus and Diogenichthys laternatus, occupied 67% of the total larval fish abundance.
The mean abundance, species number and species diversity index of the larval fish were obvious higher in Kaoping coastal waters than in Tapeng Bay. The dominant species of larval fish in Tapeng Bay were mostly sandy benthic species (Blenniidae and Gobiidae) and coastal epipelagic species (Engraulidae). The larval fish assemblage in Kaoping coastal waters was diverse, and dominated by benthic species (Sillaginidae), sandy bottom species (Blenniidae and Gobiidae), coastal epipelagic species (Engraulidae), mesopelagic species (Myctophidae) and coastal-migrant species (Scatophagidae).
