中文摘要：在水温(28±1)℃下,将体质量(1.89±0.26)g的墨吉明对虾饲养在1m^(3)的玻璃钢桶中,密度分别为60、90、120、150、180尾/m^(2),每个密度梯度设3个平行,常规饲养管理养殖15d,研究养殖密度对墨吉明对虾的生长、代谢和免疫的影响。试验期间,各组对虾存活率均为100%。试验结果显示,密度为90尾/m^(2)时,墨吉明对虾的质量增加率最高(P<0.05);密度大于90尾/m^(2)时,随着养殖密度的增加,墨吉明对虾的质量增加率随之下降;密度为180尾/m^(2)时,墨吉明对虾的质量增加率达到最低值。当养殖密度为90尾/m^(2)时,墨吉明对虾肝胰腺中谷草转氨酶、谷丙转氨酶和肌肉中琥珀酸脱氢酶的活性最高;当养殖密度为180尾/m^(2)时,墨吉明对虾肝胰腺和肌肉中谷草转氨酶、谷丙转氨酶和琥珀酸脱氢酶均呈下降趋势,而肝胰腺的免疫相关酶酸性磷酸酶和肌肉中的碱性磷酸酶、酸性磷酸酶、超氧化物歧化酶活性异常上升。试验结果表明,不同的养殖密度对墨吉明对虾肝胰腺和肌肉中谷草转氨酶、谷丙转氨酶、琥珀酸脱氢酶、碱性磷酸酶、酸性磷酸酶和超氧化物歧化酶活性均影响显著(P<0.05)。当养殖密度为90尾/m^(2)时,墨吉明对虾代谢能力与免疫力均处于较高水平,结合养殖综合效益,其适宜的养殖密度应不超过150尾/m^(2)。

外文摘要：Juvenile banana prawn Fenneropenaeus meiguiensis with body weight of(1.89±0.26)g was reared in a 1 m^(3) fiberglass tank at stocking density of 60,90,120,150 and 180 individuals/m^(2),with triplication,for 15 days under conventional feeding management at water temperature of(28±1)℃to probe into the effects of culture density on the growth,metabolism and immunity in banana prawn.During the experiment,the banana prawn had survival rate of 100%in each group.However,the maximal activities of glutamic-oxalacetic transaminase,and glutamic-pyruvic transaminase in hepatopancreas and succinate dehydrogenase in the muscle were observed in the banana prawn at stocking density of 90 individuals/m^(2).There was abnormal increase in the activity of acid phosphatase in the hepatopancreas and activities of alkaline phosphatase,acid phosphatase and superoxide dismutase in the muscle of banana prawn at the stocking density of 180 individuals/m^(2).There was significant decrease in activities of glutamic-oxalacetic transaminase,glutamic-pyruvic transaminase,succinate dehydrogenase,alkaline phosphatase,acid phosphatase and superoxide dismutase in the hepatopancreas and muscle of the banana prawn at the stocking density of 180 individuals/m^(2)(P<0.05).The higher metabolic enzyme activities and immune enzymes indices were found in the banana prawn at the stocking density of 90 individuals/m^(2) and considering the multiple benefit of the prawn culture,the proper breeding density of the banana prawn is less than 150 individuals/m^(2).
