本文描述了日本刺沙蚕Neanthesjapanica(Izuka)幼体的呼吸耗氧率,实验沙蚕1991年8月初取自在河青堆水产公司养虾池,实验采用回归正交设计。文中还根据虾池中日本刺沙蚕的平均个体重量和生物量对其种群在虾池中的耗氧量进行了估算。结果表明,日本刺沙蚕幼体的呼吸耗氧率R与体重m的关系为:R=0.2053─0.0745[(m─0.4)/0.2]+0.0197[(m─0.4)/0.2] ̄2;根据实验结果和虾池中沙蚕的平均个体重量及生物量估算的虾池中沙蚕种群耗氧量为(0.724±0.363)(0.129~1.602)g·(m ̄2d) ̄(-1),仅占该养殖结构虾池中总氧气消耗的9.13%。所以,养虾池移入沙蚕后的溶氧管理仍然是以浮游生物为主的水质管理。
In this paper, the respiratory oxygen consumption rate of Neanthesjapanica (Izuka) larvae in Japan was described. In the beginning of August, 1991, the experimental silkworms were collected from shrimp ponds of Zhaoba Hydroponics Co., Ltd., and the regression orthogonal design was used. The article also estimated the oxygen consumption of its population in the shrimp pond according to the average individual weight and biomass of the Japanese sand-thorn-silkworm in the shrimp pond. The results showed that the relationship between respiratory oxygen consumption (R) and body weight (m) was as follows: R = 0.2053─0.0745 [(m -0.4) /0.2] +0.0197 [(m- 0.4) /0.2] ~ 2; According to the experimental results and the average individual weight and biomass of the sandworm in shrimp ponds, the estimated population oxygen consumption of A. mollis in shrimp ponds was (0.724 ± 0.363) (0.129 ~ 1.602) g · (m ~ 2d) ~ (-1), accounting for only 9.13% of the total oxygen consumption in shrimp culture ponds. Therefore, the dissolved oxygen management of shrimp ponds after moving into the sandworm is still based on plankton-based water quality management.
