Relationship between Water Temperature and Oxygen Consumption Rate of the Black Scraper Thamnaconus modestus

摘要: The black scraper Thamnaconus modestus was a commercially important fish species in the 1980s, but suddenly its commercial significance decreased 1990s mainly due to continuous overfishing. Recently, order reverse depleted stocks of and help recover, seed production technology has emerged. This led farming several parts southern coast Korea. Since detailed research on metabolism relation water temperature been scanty, this investigative focus present study. standard rates (9-10 months old, total length = 22.6 ± 0.8 cm, wet weight 140.3 13.9 g) were measured at seven different settings (12, 15, 17, 20, 23, 26, 28℃) understand relationship between temperature. Relationships (WT) oxygen consumption rate (OCR) obtained as SOCR (weight-specific rate) 0.0117WT ? 0.0135 (r² 0.9351) IOCR (oxygen per individual) 1.8160WT 5.4007 9428). Q 10 (temperature sensitivity), an indicator sensitivity biological function temperature, analyzed. In our experiment, when increased, value decreased. 6.27 waters where ranged from 12-15℃ much higher than values temperatures (1) 15-23℃ (2) 23-28℃. Consequently, it shown that is warm inhabiting range 15-28℃ deemed appropriate.
