경남 통영해역의 뜬말에 서시하는 방어 유어에 관한 연구

Abstract

Young Seriola quinqueradiata associated with drifting seaweeds weye investigated monthly between April 1998 and March 1999 in the coastal area of Tongyeong, Korea, The most abundant types of seaweed were in the genus Sargassum, including S. horneri, S. miyabei and S. thunbergii. The size of seaweed patches varied by season: patches larger than 4 m in diameter were found in May, whereas patches smaller than 0.5 m in diameter were abundant in August and September. Young Serioia quinqueradiata ranged from 12.9 to 135.4 mm in total length were collected from May to July at the study area. The striped bands on the bodies of young Seriola quinqueradiata were developed at 10.0 ~ 15.0 mm in total length and increased up to 12 bands with growth, These bands were gradually disappeared at 130.0 ~ 150.0 mm in total length. There was no significant relationship between the number of Seriola quinqueradiata collected and the weights of the seaweed patches ( r^2=0.04,P<0.05 ).
