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0.019 1W-0.236 81.065T和0.009 8W-0.077 01.120 1T.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3.566 5 和4.892 6 μg·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14 565.17和1 635.94 mg·m-2.在0,5.0,10.0,15.0,20.0 ℃,氨氮排泄率分别为0.009 3,0.059 3,1.148 4,2.143 4,2.782 7 μg·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8 283.93,1 302.05 mg·m-2.

Abstract: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-0.236 81.065T and 0.009 8W-0.077 01.120 1T,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.
