摘要
太平洋牡蛎二倍体和三倍体软体肉重和生化成分含量的周年变化表明,牡蛎软体 肉重和3种生化成分含量的变化与牡蛎繁殖季节密切相关。 三倍体周年软体肉重、糖元和 脂类含量均比二倍体高,水分含量比二倍体低,三倍体蛋白质含量在1~7月份比二倍体 低,8~12月份比二倍体高。三倍体人分含量除5月份外,均比二倍体高。本文还就二倍体 和三倍体3种生化成分含量的周年变化与牡蛎繁殖季节的关系进行讨论。
Annual changes of meat weight and biochernical composition between diploids and triploids were comparatively studied in the Pacific oyster,Crassostrea gigas. The results indicates that the content changes in meat weight, protein,lipid and glycogen of the soft body in oyster are closely related to its reproduction season. Annual meat weight,glycogen and lipid of triploids were higher than those of diploids, but lower in water content. Proteins content of triploids is less from Jan. to July,but higher than diploids from Aug. to Dec.. A annual ash content of triploids exceeds the diploids except May. The relationship of the biochemical composition changes with the reproduction seasons is discussed in the paper.
