Abstract

1.This paper investigated the bioenergetic responses of the sea cucumber Apostichopus japonicus (wet weights of 36.5±1.2 g) to different water temperatures (5, 10, 15, 20, 25 and 30 °C) in the laboratory.2.Results showed that theoretically the optimal temperatures for energy intake and scope for growth (SFG) of sub-adult A. japonicus was at 15.6 and 16.0 °C, respectively. The aestivation threshold temperature for this life-stage sea cucumber could be 29.0 °C by taking feeding cessation as the indication of aestivation.3.Our data suggests that A. japonicus is thermo-sensitive to higher temperature, which prevents it from colonising sub-tropical coastal zones. Therefore, water temperature plays an important role in its southernmost distribution limit in China.4.The potential impact of global ocean warming on A. japonicus might be a northward shift in the geographical distribution.
