Diurnal rhythm of filtration rate of Zhikong scallop Chlamys farreri veliger and spat
摘要
Abstract
The Zhikong scallop spats' (1. 177~2. 017 mm in shell length) diurnal rhythm of filtration rate were determined using static water method. For spats, the microalgae density was 3. 0× 104 cell/ml and the temperature was 24 ± 0. 5℃ , and for veliger, the microalgae density was 1. 0× 104cell/ml and temperature was 18 ± 0. 5 ℃. We measured the filtration rate of the veliger and spat at 17 · 00,21 · 00,01 = 00,05 = 00,09 = 00, and 13 · 00. Analysis showed that the filtration rate of the veliger and spat had similar diurnal rhythm. They had the lowest filtration rate (veliger; 0. 002 6 ml/h · ind ,spat: 0. 123 1 ml/h · ind) in the daytime(9: 00 - 13 : 00) and the highest one(veliger: 0. 025 8 ml/h · ind;spat: 0. 509 6 ml/h · ind) in the night(21 : 00 - 1 : 00). There were significant difference between the highest and the lowest value(P<0. 01).关键词
