于 1996年 5～ 9月 ,测定了 3种规格 ( 0 .2 71± 0 .0 41g、3 .5 0 9± 0 .3 0 1g、11.0 62± 1.0 2 7g)池塘养殖中国对虾 (Penaeuschinensis)在 2 0℃、2 5℃和 3 0℃下 ,摄食日本刺沙蚕 (Neanthesjaponica)的C收支 .结果表明 ,温度和体重对摄食C有显著影响 ,随温度升高和体重的下降 ,C的摄食量显著增大 ,在 2 0℃、2 5℃和 3 0℃下的平均C摄食量分别为 12 .41、19.12和 2 6.0 8mg·g-1·d-1,在 3个规格下的平均C摄食量分别为 3 6.0 6、12 .17和 9.3 8mg·g-1·d-1.不同规格中国对虾对摄食C的分配比例无显著影响 ,温度是影响中国对虾摄食C分配的主要因素 .在 3个温度下摄食沙蚕的生长C、排粪C、蜕壳C和代谢C占摄食C的平均分配比例分别为 3 1.2 3 %、4.3 8%、7.94%、5 6.45 % ;2 6.83 %、2 .92 %、6.69%、65 .79% ;16.86%、2 .3 8%、5 .99%和 74.76% .
From May to September 1996, three species of pondworm (Penaeus chinensis) were tested in three ponds (0.221 ± 0. 41g, 35.09 ± 0.301g, 11.062 ± 1.027g) The results showed that the temperature and body weight had significant effects on the C intake at 20 ℃, 25 ℃ and 30 ℃, with the increase of temperature and body weight, C , The average food intake at 20 ℃, 25 ℃ and 30 ℃ were 12.41, 19.12 and 6.08 mg · g-1 · d-1, respectively. Under the three specifications The average C food intake was 3 6.06, 12.17 and 9.3 8 mg · g-1 · d-1, respectively.The distribution of dietary C was not significantly affected by the different specifications of Penaeus chinensis, and the temperature was the main factor influencing the distribution of dietary C The average distribution ratio of growth C, defecation C, molting C and metabolism C to feeding C at 3 temperature were 3 1.2 3%, 4.3 8%, 7.94%, 5 6.45% respectively; 2 6.83%, 2.92%, 6.69%, 65.79%; 16.86%, 2.38%, 5.99% and 74.76% respectively.
