摘要
根据池养对虾生长情况的现场测量数据,通过回归分析求得体长及体重的生长方程式分别为:L_t=14.0733[1-e^(-0.1403(t-0.8350)]和W_t=33.4479[1-e^(-0.1403(t-0.8350))]~3,体重生长曲线的拐点t’=8.7。对虾在池塘中的实际生长速度由于受池塘生态环境及鲜活饵料供应的季节性变化等因素的影响,分别在7月上旬、8月上旬及9月中旬出现三次生长高峰。适当减少高温期即7月中旬至8月上旬鲜活饲料的投喂量,可避免在8月中旬由于池塘水质及底质恶化而引起的病害及浮头泛塘现象,有利于为对虾的后期生长提供良好的池塘环境条件。
The growth of Penaeus orientalis cultured in earthen ponds has been conducted. The relationship between the age (t, a period of 10 days) and the body length (L, cm) can be expressed by the equation Lt= 14.0733 [1 -e-0.1403(t-0.8350] .The age (t, a period of 10 dags) and body -weight (W, g) relationship can be described as Wt = 33. 4479 [1-e-0.1403(t-0.8350)]3.The growth inflection point t = 8. 7. There were fluctuations of growth because of the diferent quality of the pond water. To avoid the effects of environmental stress on the growth of penaeus arientalis , it is necessary to reduce feeding dose in high tem-perture period.
