淡水白鲳人工繁殖和苗种培育试验

An Experiment in Artificial Propagation and Cultivation of Colossoma SP. Fries

淡水白鲳(Colossoma SP)原产南美亚马逊河,属热带、亚热带经济鱼类,具有个体大、生长快、食性杂、耐低氧、广盐性、适密养、易捕捉、抗病力强和刺少肉质鲜嫩清甜等优点。1986年10月引进我省,经三年多的反复试验,于1990年5月,取得了人工繁殖和苗种培育成功。本文比较详细地总结了淡水白鲳亲鱼的强化培育,人工催产和苗种培育方法以及成功经验。

Colossoma SP. originlly grew in the Amazon, South America, is a kind of tropical or subtropical economic fish which is noted for its size, its growing speed, omnivorousness,low-oxygn resistance , and wide salinity tolerance . It is suitable for dense cultivation and easy for fishing. In addition, it has strong disease resistance and delicacy of meat with little bones. Colossoma SP. was introduced into Hainan province in October 1986 and, after 3 years of repeated experiments, success for its artifical propagation and cultivation was achieved in May 1990. This paper presents a comparatively minute. summary account for the intensified breeding of the parent Colossoma SP. fish, and the method as well as the successful experience for its artificial delivery and cultivation.
