北海道立水产孵化场养殖技术部和病理环境小组使用异质3倍体化技术使鲑·鳟鱼类获得了抗病性。主要是利用3倍体化技术使营养成分(用于生殖腺发育的)返回到体内,使鱼的味道变得更加鲜美。该项技术作为赋予抗病性的技术向实用化迈进了一步。于4月1～5日在东京召开的日本水产学会发表了该成果。 如果培育出具抗病性的鱼种和杂种,在没有抗性的鱼种中有时也会出现抗性。但是,也有由手鱼种的不 Hokkaido Aquaculture Hatchery Farming Technology and the Pathology Group used salmon trout to gain disease resistance using heterogeneous triploidy techniques. The main is the use of 3 ploidy technology so that nutrients (for gonadal development) back to the body, so that the taste of fish to become more delicious. This technology takes a step toward practicality as a disease-conferring technology. The results were presented by the Japan Society of Fisheries, which was held in Tokyo on April 1-5. Resistance is sometimes found in non-resistant species if breeding disease-resistant species and hybrids. However, there is not by hand fingerling
