Abstract

Seasonal fluctuation in abundance and species composition of fish in coastal waters off Dolsan island were investigated using seasonal samples collected by an otter trawl in 2012. A total of 4,848 fishes were sampled and classified into 52 species, 29 families, and 7 orders. The dominant species was Leiognathus nuchalis (2,786 individuals, 57.5%), Amblychaeturichthys hexanema (164 individuals, 3.4%), and Ilisha elongata (141 individuals, 2.9%). The highest number of individuals was found in summer (2,174 individuals), while the lowest number of individuals was found in winter (321 individuals). The diversity index was the highest in spring (H'=3.06) and the lowest in summer and fall (H'=1.77). Temperature was the principal factor to determine the collected number of individuals (r=0.94) and the number of species (r=0.83).

여수 돌산 연안에서 소형기선저인망에 어획된 어류의 종조성 및 계절변동을 연구하기 2012년에 계절별로 4개의 정점에서 조사하였다. 어획된 어류는 총 7목 29과 52종이었고, 4,848개체가 어획되었다. 이 중 농어목이 12과 20종으로 가장 많은 출현 종수를 보였고, 우점종은 주둥치(2,786개체, 57.5%), 도화망둑(164개체, 3.4%), 준치(141개체, 2.9%) 순이었다. 가장 많은 개체수가 출현한 계절은 2,174개체가 어획된 여름이었고, 겨울에 321개체로 가장 적은 개체가 어획되었다. 다양도 지수는 봄에 3.06으로 가장 높았고, 여름과 가을에 1.77로 낮게 나타났다. 또한, 수온은 출현 개체수 (r=0.94)와 출현종 (r=0.83)을 결정하는 주요 요인이었다.
