     This paper reported the process and result of artifical propagation and breeding of Plectorhynchus pictus by Fujian Fisheries Research Institute in 2001. Parent fishes were acceleratedly bred with the use of DOM, LRH-A2(LRH-A3), and HCG mixedly or respectively in temperature-rasied water. At seawater temperature 20.1-26.8℃ and salinity 20.8-26.0 , the effective time was about 36-40hrs.

The spherical fertilized ova were obtained from artifical propagation. The ovum is about 0.95 mm. in diameter. Within the ovum a single large oil-globule is present, 0.45--0.5 mm. in diameter. Fertilized ova were incubated in running water with a salinity of 8--10‰. At the water temperature of 16.8—22℃ the first cleavage begins at 75 min., the germ ring appears at 10h, and the closure of blastopore occurs at 24 h after fertilization. ova hatch at 48 h. The newly batched larvae are 2.5 mm. in length.

从梭鱼人工繁殖所获之受精卵中,取得胚胎发育的观察材料。卵的直径约0.95毫米,具单个油球,油球的直径0.45—0.5毫米,受精卵在盐度为8—10‰的流水中孵化。水温在16.8—22℃的范围内,受精后1小时15分,开始第一次分裂;6小时,形成囊胚;10小时左右,出现胚环;24小时左右,原口闭合,胚体具有2—3对体节,受精后48小时,胚体脱膜而出,从而结束了胚胎发育阶段。孵出当天的鱼苗,长2.5毫米。

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.

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。
