ABSTRACT

Sea perch (Lateolabrax japonicus), which naturally inhabits in the coastal areas of China, Japan and the Korea peninsula, has been cultivated widely in China in recent years and a great deal of research has also been conducted on the control of reproduction [1]. The long-term preservation of sea perch sperm will simplify the production of selected strains and facilitate genetic selection of beneficial traits for intensive commercial farming [2]. In addition, the wild stock of sea perch is declining because of excessive exploitation and environmental pollution. Constructing a cryobank of sea perch semen is becoming more and more urgent.
