II. Routine oxygen consumption, maximum oxygen consumption and metabolic scope at three temperatures

摘要: Larvae of the northern shrimp Pandalus bore- alis (Kroyer) are pelagic. In Estuary and Gulf St. Lawrence, Canada, early stages found in upper 25-m water column spring summer expected to experience a range temperatures from as low 0� C high at 6� C. Little is known impact temperature on meta- bolic requirements larvae. this study, routine respiration (VO2), maximum (electron transport system activity, ETSA) scope for growth (MS, ETSA-VO2) larvae were measured function tempera- ture (3, 5 8� C), developmental stage (I-V 3� C, I- VII 5� C) rate dry mass. After logarithmic transformation, all three metabolic variables linearly related The increase VO2 with body mass was faster than 3 or whereas ETSA slower. As result, MS increased more slowly 3a nd However, did not limit since it explained only 39% variability growth. All well varied together ontogeny. Q10 ranged 1.6 2.2 I-V larvae, except I (3.9) III (2.9).
