Abstract
An experiment was conducted to investigate the effects of four water temperatures (10, 15, 20, and 25∘C ) in combination with three photoperiods (24L:0D, 12L: 12D, and OL:24D) on the oxygen consumption rate of juvenile dark-banded rockfish, Sebastes inermis (mean body weight 20.5±0.7g ). The oxygen consumption rates of S. inermis were measured in triplicate for 24 hours using a continuous flow-through respirometer. Different combinations of water temperatures and photoperiods resulted in significant differences in the mean oxygen consumption rate of S. inermis (P 25∘C ranged 178.3∼283.5,386.7∼530.7,529.2∼754.3 and 590.0∼785.5mg O2 kg−1h−1 , respectively. Q10 values ranged 3.17∼5.51 between 10 and 15∘C,1.87∼2.10 between 15 and 20∘C and 1.08\siml.24 between 20 and 25∘C , respectively. Fish held in continuous darkness (OL:24D) used consistently less okygen than fish exposed to continuous light (P 10∘C . The oxygen consumption of fish exposed to the 12L:12D photoperiod was significantly higher during the light phase than during the dark phase under all temperature treatments except $10^{\circ}C\;(P . This study provides empirical data for estimating oxygen consumption of S. inermis under given condition. This result has application for culture management and bioenergetic model for growth of this species.
