Species composition and seasonal variation of fish assemblages in Sargassum beds in Gamak Bay was determined using fish samples collected monthly by a surrounding net from October 2008 to September 2009. A total of 21 species, 582 individuals and 5,345.1 g of fishes were collected during the study period and Perciformes accounted for 47.6 % of the total number of species. Takifugu niphobles, Engraulis japonicus and Lateolabrax japonicus predominated in number, accounting for 55 % of the total number of individuals. Higher number of species and individuals occurred in June and in September-October. Species were grouped into three by cluster analysis: A) dominant species such as Leiognathus nuchalis and Takifugu niphobles, B) fish collected mainly in spring such as Sebastes inermis, Chaenogobius heptacanthus, Pterogobius zonoleucus, Pholis nebulosa, and Trachyrhamphus serratus, and C) fish collected mainly in autumn such as Engraulis japonicus, Lateolabrax japonicus, and Hyporhamphus sajori. 가막만 모자반 군락에서 2008년 10월부터 2009년 9월까지 월별로 두릿그물로 어류를 채집하여 어류의 종조성 및 계절변동을 분석하였다. 조사기간 동안 21종 582 개체, 5,345.1 g의 어류가 채집되었으며, 출현한 어종 중 복섬(Takifugu niphobles), 멸치(Engraulis japonicus)와 농어(Lateolabrax japonicus)가 전체 개체수의 55 %를 차지하였다. 12월과 1월에는 어류가 채집되지 않았고, 봄에 수온이 상승하며 증가하여 출현종수와 채집량이 6월에 높았고, 7월과 8월에는 감소하였으나, 9월과 10월에는 높은 값을 보였다. 종간 유사성을 집괴분석한 결과 3개의 무리로 구분되었다. A 그룹에는 출현기간이 비교적 긴 우점종인 주둥치(Leiognathus nuchalis)와 복섬(Takifugu niphobles)이, B 그룹에는 봄에 주로 출현한 볼락(Sebastes inermis), 살망둑(Chaenogobius heptacanthus), 흰줄망둑(Pterogobius zonoleucus), 베도라치(Pholis nebulosa), 거물가시치(Trachyrhamphus serratus), C 그룹에는 가을에 주로 출현한 멸치(Engraulis japonicus), 농어(Lateolabrax japonicus), 학공치(Hyporhamphus sajori)가 포함되었다.

살조개의 안정적인 인공종묘생산을 위한 기초 연구로서 수온별 난발생, 먹이생물, 밀도에 따른 유생의 성장과 생존율을 조사하였다. 살조개의 발생가능 수은은 $15{\~}30^{\circ}C$인 것으로 나타났으며 초기 D형 유생에 이른시간은 $15^{\circ}C$에서 $30^{\circ}C$까지 각각 39.7, 31.2, 26.8, 26.2시간이 소요되었다 수온별 유생사육에서는 $30^{\circ}C$에서 성장과 생존율이 가장 양호하였다. 사육밀도에 따른 성장과 생존율은 4${\~}$6 ind./ml의 밀도에서 가장 적합한 것으로 나타났다. 식물먹이생물에 따른 성장과 생존율은 Isochrysis galbana, Pavlova lutheri, Chaetoceros calcitrans를 혼합 공급하는 것이 가장 효과적이었다. 먹이생물농도에 따른 성장과 생존율은 $1{\times}10^4$ cells/ml에서 $218{\mu}m$와 $45\%$로 가장 높았다. In order to obtain the aquaculture fundamental data far resources enhancelnent of the Protothaca jedoensis, the egg development and larva growth were investigated at different conditions such as water temperature, phytoplankton and density. Water temperature, at which P. jedoensis egg successfully completed development, ranged from $15{\~}30^{\circ}C$. The required time from fertilization to D-shaped larva was 39.7 hours at $15^{\circ}C$, 31.2 hours at $20^{\circ}C$, 26.8 hours at $25^{\circ}C$ and 26.2 hours at $30^{\circ}C$ P. jedoensis. In regard to water temporature, growth and survival rates of larvae were high at $30^{\circ}C$. In growth and survival rates of larvae with various rearing densities, the highest aver-age growth and survival rates were 4${\~}$6 ind./ml When larvae were fed mixed phytoplankton, such as Isochrysis galbana, Pavlova lutheri and Chaetoceros calcitrans, their growth and survival rates were the high among the groups. In growth and survival rates of larvae with various rearing food concentrations, the highest average growth and survival rates were $218{\mu}m$, and $45\%$ at the food concentration of $1{\times}10^4$ cells/ml, respectively.

For the biosystematic studies on the marine benthic invertebrates in East china Sea, a faunal and ecological study on benthos was camed out. The materials were collected from East chain sea, by qualitative and quautitative sampling methods. Bentic animals collected during the study were identified 3 phylums (Arthropoda, Mollusca, Echinodermata). The dominant species investigated in these site to the importance value were as follow : Class Cephalopoda, Class Gastropoda, and Order Decapoda (Family Penaedae, Family Portunidae) in Phylum Arthropoda and Class Stelleroidea in Phylum Echinodermata. The most dominant Phylum was Echinodermata. Based on this data we could judge a most useful faunal were Mollusca, and Anthropoda and Asterias amurensis, Acaudina molpioides in Echinodermata were most plented speceies. Eventhough we can t use of these two species in Echinodermate so, we must not forget about these plentfulness.
