日本成功培育透明金鱼 心脏脑袋清晰可见
北京时间12月30日消息,日本研究人员继透明青蛙后,成功培育出可透过透明鳞片及皮肤,看见心脏跳动的金鱼。
研究人员致力于透过这类透明生物,降低解剖的必要性。解剖在学校等机构引起的争议性越来越大。
三重大学(Mie University)生物资源学研究科副教授田丸浩(Yutaka
Tamaru)说:“鱼鳞和皮肤都没颜色,所以能看见活生生的心脏及其它器官。”
他说:“不需要解剖,就能看见金鱼黑眼睛上方有很小的脑袋。”
三重大学及名古屋大学(Nagoya
University)团队的研究人员挑出突变的浅色金鱼,并集中交配繁殖,培育出该“琉金”(ryukin)金鱼。
田丸透露:“在水族馆,浅色对金鱼来说是缺点。但能以立体角度看清器官在体内的状态,是再好不过了。”
他表示,这种金鱼有约20年寿命,能成长到约25公分长,重逾2公斤,比斑马鱼等实验常使用鱼还大
