Marked elevations of hemolymph glucose titers, which peaked within 2 hr, were observed in both intact and bilaterally eyestalk-ablated prawns, Macrobrachium rosenbergii, when they were transferred directly from their optimal temperature of 28 ℃ to lower temperatures close to the lethal limit. Hyperglycemia can therefore be considered a characteristic response in this species under cold shock. Involvement of biogenic amines in the hyperglycemic response was also demonstrated. Hyperglycemic effects of epinephrine, dopamine and serotonin were mediated through CHH at the eyestalk level, but the response under cold shock was not exclusively mediated through CHH. It is suggested that factor(s) other than CHH are involved in the hyperglycemic response, possibly norepinephrine or/and octopamine.application/pdf54237 bytesapplication/pdfzh-TW國立臺灣大學漁業科學研究所週日韻律生物胺低溫壓迫淡水長臂大蝦Circadian rhythmbiogenic aminescold shockfreshwater giant prawnjournal articlehttp://ntur.lib.ntu.edu.tw/bitstream/246246/20535/1/872611B002004.pdf
