최첨단 연구로 성장하고 있는 해양생물공학 연구 중 염색체공학 연구의 배수체 조작, 성분화, 자성 발생, 형질전환 어류와 유전자 조작에 관한 최근의 연구 동향을 분석하고 향후 발전 방향에 관하여 살펴보았다. 배수체 연구 중 3배체 어류 생산 연구는 20여종의 어류들 중 무지개 송어와 메기가 물리적 충격을 이용한 실험법으로 산업적으로 이용 가능한 수준에 있다. 성분화를 포함한 약 15종의 고급 어종이 방사선 투사법에 의해 자성 발생 2배체를 생산 유도하였다

Present study was aimed to summary the recent reports of chromosomal technology such like a polyploidv, sex differentiation, gynogenesis, transgenic fish and gene manipulation. Triploid cells for rainbow trout and channel catfish were induced through thermal shocks of varying temperature levels and produced as a industrial use. A monosex fish with homogametic females of 15 species of high valued fish were produced by exposing to irradiation. It seemed that different irradiation was suitable to inactivate the sperm and block the formation in producing the gynogenetic diploids. Since 1985, transgenic fish have been successfully produced by microinjecting or electroporating desired foreign DNA into unfertilized or newly fertilized eggs using about 40 fish species. More recently, transgenic fish have also been produced by infecting newly fertilized eggs with pantropic, defective retroviral vectors carrying desired foreign DNA. These transgenic fish can serve as excellent experimental models for basic scientific investigations as well as in marine biotechnological applications.
