本文报道了对栉孔扇贝呼吸与异常呼吸研究的初步结果。栉孔扇贝成贝(平均壳高6.4cm)的呼吸表面为9.75cm~2/g湿肉,鳃纤毛在12ppm的呋喃西林海水溶液和50ppm的青霉素海水溶液中剧烈收缩。在密闭容器中,用温克勒法测出成贝软体的平均耗氧量为0.044ml/(g·h),幼贝(壳高1.9—4.2cm)软体的平均耗氧量为0.058ml/(g·h),面盘幼虫(壳长145.5μm)平均日耗氧量为0.0134μl/个,其窒息点为4.0ml/L。 成贝离水12h后死亡率为5.6％,体重减少16.2％;幼贝离水6h以内无死亡个体,贝苗(壳高1cm)离水4h后死亡率为15％;稚贝(壳高400—600μm)离水后1h的脱落率为33.3％。
This article reports the preliminary results of the study on respiration and abnormal respiration of C. farreri. The respiration surface of the scallop scallops (average shell height 6.4 cm) was 9.75 cm 2 / g wet meat and the gill cilia contracted violently in a 12 ppm nitrofurazone aqueous solution and a 50 ppm penicillin aqueous solution. In the airtight container, the average oxygen consumption of the soft shellfish was 0.044ml / (g · h) and the average oxygen consumption of the shellfish (shell height 1.9-4.2cm) was 0.058ml / (g · h). The average daily oxygen consumption of faceplate larvae (shell length 145.5μm) was 0.0134μl / s and its suffocation point was 4.0ml / L. The death rate was 5.6% and the body weight was decreased by 16.2% after 12 hours of water leaving. The death rate of baby shellfish was less than 6 hours from the water, and the death rate was 15% -600μm) 1h after the water off rate of 33.3%.
