经过n-3HUFA强化培育的卤虫无节幼体的n-3HUFA、EPA和DHA的含量明显提高,投喂给日本川鲽幼苗后,能够改变幼鱼体内脂类和脂肪酸组成,提高幼鱼的生长速度、存活率和应激抵抗能力,并且对其它一些鱼类的着色、视力等方面也起着重要作用。

Follicle stimulating hormone β (FSHβ) of Japanese flounder (Paralichthys olivaceus) plays a key role in the regulation of gonadal development.This study aimed to investigate molecular genetic characteristics of the FSHβ gene and elucidate the effects of single nucleotide polymorphisms (SNPs) of FSHβ on reproductive traits in Japanese flounder.We used polymerase chain reaction single-strand conformation polymorphism (PCR-SSCP) and sequencing of the FSHβ gene in 60 individuals.We identified only an SNP (T/C) in the coding region of exon3 of FSHβ.The SNP (T/C) did not lead to amino acid changes at the position 340 bp of FSHβ gene.Statistical analysis showed that the SNP was significantly associated with testosterone (T) level and gonadosomatic index (GSI) (P<0.05).Individuals with genotype TC of the SNP had significantly higher serum T levels and GSI (P<0.05) than that of genotype CC.Therefore, FSHβ gene could be a useful molecular marker in selection for prominent reproductive trait in Japanese Flounder. 展开更多
