根据季节、性别、大小和摄食率对罗氏沼虾（Macrobrachium rosenbergii）的总血细胞计数（THC）进行了研究。对虾注射外来物质时的四氢大麻酚也被调查了。四氢大麻酚含量最高的季节是秋季，最低的季节是冬季，雌雄对虾之间以及体重7 ~ 115 g的对虾之间的四氢大麻酚含量差异不显著。四氢大麻酚在D-3期最低，在C期最高。在0.1%、0.5%、1.0%和1.5%体重日饲喂率中，以01%饲喂率的四氢大麻酚含量最低（-1）。碳粉和肠球菌注射对虾在前6 h THC升高，生理盐水和碳粉注射对虾30 h THC最低，54 h后恢复正常，肠球菌注射对虾42 h THC最低，且恢复延迟。(C) 2001学术出版社。
The giant freshwater prawn Macrobrachium rosenbergii was investigated for its total haemocyte count (THC) based on season, sex, size and feeding rate. The THC, when the prawns were subjected to injections of foreign materials was also investigated. The prawns displayed the highest and lowest THC in autumn and winter respectively, with no significant difference between male and female, or among animals with a body weight range of 7-115 g. The prawns displayed the lowest THC at D-3 stage, and the highest in C stage. The prawns displayed the lowest THC when they were fed at 01% feeding rate among feeding rates of 0.1%, 0.5%, 1.0% and 1.5% body weight day(-1). Prawns injected with carbon powder and Enterococcus showed increased THC during the first 6 h. Prawns injected with saline and carbon powder had the lowest THC after 30 h, and recovered to the normal value after 54 h. Prawns injected with Enterococcus showed the lowest THC after 42 h, and showed delayed recovery. (C) 2001 Academic Press.
