中文摘要:

室内模拟实验测定了污损生物麦秆虫Caprella sp.在不同温度时的氨氮和活性磷酸盐的排泄特征.活性磷酸盐和氨氮的排泄率分别可表示为0.0191W^-0.23681.065^T和0.0098W^-0.07701.1201^T.2种营养盐的排泄率均随温度升高而升高,随体重增加而降低.低于10.0℃,活性磷酸盐排泄会受低温的限制;在15.0,20.0℃,活性磷酸盐的排泄率分别是3.5665和4.8926μg·g^-1·h^-1;麦秆虫附着的养殖设施在夏、秋季节对水体活性磷酸盐的贡献可达14565.17和1635.94mg·m^-2.在0,5.0,10.0,15.0,20.0℃,氨氮排泄率分别为0.0093,0.0593,1.1484,2.1434,2.7827μg·g^-1·h^-1;麦秆虫附着的养殖设施在夏、秋季节对水体氨氮的贡献可达到8283.93,1302.05mg·m^-2.

英文摘要:

Phosphate and ammonia-N metabolism characteristics of the fouling organism, Caprella sp. at different water temperature were studied by indoor experiment. Phosphate excretion rate and ammonia-N excretion rate were 0. 019 1W^-0.23681 1.0656T and 0.009 8W^-0.07701. 120 1^T, respectively. They both increased with water temperature while decreased with wet body weight. Under 10.0 ℃, the phosphate metabolism might be restrained by low temperature. At 15.0 and 20.0 ℃, phosphate excretion rate was 3. 566 5 and 4. 892 6 μg·g^-1·h^-1, respectively. Thus, phosphate release rate of fisheries facilities attached by Caprella sp. was estimated as 14 565.17 and 1 635.94 mg· m^-2 in the whole summer and autumn. At 0,5.0, 10.0, 15.0 and 20.0 ℃, the ammonia excretion rate was 0. 009 3,0. 059 3, 1. 148 4,2. 143 4 and 2.782 7 μg·g^-1·h^-1 ,respectively. And 8 283.93 and 1 302.05 mg·m^-2 was the ammonia production rate of fisheries facilities in summer and autumn, respectively.
