栉孔扇贝三倍体与二倍体的排泄研究

从温度变化、个体大小和昼夜变化等３个角度研究栉孔扇贝（Ｓｃｈｌａｍｙｓ ｆａｒｒｅｉ）三倍体与二倍体的排泄率。结果表明，栉孔扇贝三倍体与二倍体的排泄率均随温度升高而增大；不同壳宽排泄率（Ｎ）与温度（ｔ）的关系为：Ｎ＝７．２０３３ｅ＾０．１２１５ｔ，Ｒ＾２＝０．８４４１（三倍体ｓ组，壳宽约３．２ｃｍ）；Ｎ＝８．８１５３ｅ＾０．１０３１ｔ，Ｒ＾２＝０．９８６３（三倍体ｂ组，壳宽约４．３ｃｍ）；Ｎ＝６．

Studies on excretion of triploid and diploid Chlamys farreri

The ammonia excretion rate, as well as its day and night variation in triploid and diploid scallop, Chlamys farreri was studied at different temperatures and body sizes. The results show that the ammonia excretion rates (N) of both triploid and diploid scallops increase when the temperature (t) rises; the relationships between N and t can be expressed by the following equations: N=7.203 3e 0.121 5 t ,R 2=0.844 1(triploid group s, shell width about 3.2 cm);N=8.815 3e 0.103 1 t ,R 2=0.986 3(triploid group b, shell width about 4.3 cm); N=6.426 6e 0.132 3 t ,R 2=0.870 5(diploid group s, shell width about 3.0 cm);N=7.805 5e 0.107 9 t ,R 2=0.913 9 (diploid group b, shell width about 4.4 cm).The ammonia excretion rates of both triploid and diploid scallops decrease with the increase of body size; the ammonia excretion rates are different between day and night in both triploid and diploid scallops; there are not distinct difference in ammonia excretion rate between triploid and diploid scallops by t-test.
