서식어장별 수온？염분이 섬진강 강굴(Crassostrea ariakensis)의 성장에 미치는 영향

Abstract

- This study was carried out to obtain the biological fundamental data for the resourcesannexation of Crassostrea ariakensisin terms of the effect of temperature and salinity on growth.Water temperature during the sampling period was 3.5~ 26.2C and there was a little differencebetween each sites. Salinity was ranged from 2.6 to 29.5 psu, its maximum in Baealdo and itsminimum in Dontak. The fatness index was the higher in Dontak than the other sites. In August,the value was the lowest in 3 sites. Therefore Crassostrea ariakensisis likely to have spawningperiod June and July. Size values (mean± S.D.) of shell height was 149.7± 19.8 m (Baealdo),148.6± 21.3 mm (Seomjin bridge) and 143.1± 17.6 mm (Dontak), respectively. Relative growthequations among SH, SL, SW, TW and MW of Crassostrea ariakensiswere ranged from 0.024 to0.0471.
