摘要
1996年6月~1997年6月,在基本相同的条件下对红鳍东方与假睛东方的生长速度、饲养成活率、体型与体态和行为习性等方面的差异进行了对比观察试验。试验结果表明,红鳍东方的生长速度比假睛东方快,饲养成活率比假睛东方高13.2%-15.6%。外部形态色泽较稳定,而假睛东方变异较大。红鳍东方平均游速为0.5m/s,集群游动性较强,假睛东方平均游速为为0.33m/s,性较凶残,体型较丰满。二者都具有广盐性,但都不适于长期在纯淡水中生存。二者的最适水温均为16-23℃。
Observation of the growth,survival rate,body shape and body appearance of Fugu rubripe and Fugu pseudommus form June 1996 to June 1997 under the controlled culture conditions showed that Fugu rubripe not only grew faster but had survival rate about 13. 2~15. 6% higher than that of Fugu pseudommus. The appearance tint of Fugu rubripe was more steady than that of Fugu pseudommus. With Fugu rubripe often swam around(at 0.5m/s)in schools.The relationship between body length and body weight of Fugu rubripe is W=3. 6293L3.0000×10-5. As the body shape is fuller than that of Fugu rubripe, the swimming velocity of Fugu psudommus is 0.33m/s.The relationship between body length and body weight of Fugu pseudommus is W=3. 5040L 3.0169×10-5.Both species can live in the water with wide range of salinity,but cannot live in fresh water for along time. The optimal growth water temperature for both species is form 16 to 23℃.
