刺鲃主要分布于我国南方各地,是名贵经济鱼类之一。刺鲃肉质较嫩,营养丰富,食性较广,市场前景广阔,池塘混养当年种8个月即可达0.5kg的上市规格,池塘养殖最大个体能达到5kg以上,是一种开发前景较好的养殖品种。由于近年来生态环境破坏,以及过度捕捞等不良渔业行为导致刺鲃资源量急剧下降,人工繁殖成为当务之急。下面将其亲鱼培育技术介绍如下: 一.刺鲃的生物学特性 刺鲃为中下层杂食性鱼类,稍偏动物性。无论是植物性、动物性饵料还是浮游生物、有机碎屑都可食用。由于它营中下层生活,混养时可充分利用剩余饵料资源。由于是从野生鱼类中驯化而来,刺鲃的适应性特别广,疾病特别少,抗病力强。无论是水库、池塘、山溪、网箱中都可饲养,但在饲养捕捞时,应注意它性急躁、易跳跃的特点。
Stingray is mainly distributed in all parts of southern China, is one of the precious economic fish. Prickly sperm quality is tender, nutritious, broad diet, the market prospects are broad, the pond polyculture species that can be up to 0.5kg 8 months to market specifications, the largest individual pond farming can reach more than 5kg, is a better development prospects Of breed. Due to the destruction of the ecological environment in recent years and the adverse fishery behavior such as over-fishing, the amount of Ciliotapin resources has dropped sharply, and artificial breeding has become a top priority. Below the broodstock breeding technology introduced as follows: A. thorn biological characteristics of stingray for the middle and lower omnivorous fish, slightly animalistic. Whether plant or animal bait or plankton, organic crumbs are edible. As it lives in the lower middle class, polyculture can make full use of the remaining food resources. Due to domestication from wild fish, the adaptability of the stingray is particularly wide, the disease is extremely few and the disease resistance is strong. Whether it is reservoirs, ponds, mountains, cages can be kept, but when feeding and fishing, it should be noted that it is impatient, easy to jump characteristics.
