异育银鲫系列养殖技术及其生物学特性的研究

STUDIES ON A SERIES OF CULTIVATED TECHNIGUES AND BIOLOGICAL CHARACTERS OF ALLOGYNOGENETIC CRUCIAN CARP——(Carassius auratus gibelio)

为改变江淮地区以花白鲢为主体的传统池塘养殖结构,增加优质鱼放养比重,提高产量及经济效益,我们于1984-1988年间对异育银鲫系列养殖技术及其生物学特性进行了研究,找出池塘主混养异育银鲫系列养殖技术的主要参数.通过相关的生物学测定证实,异育银鲫生长速度比白鲫快0.44倍,比本地鲫快1.02-1.52倍;其肉质营养丰富,食性杂,适应性强,疾病少,容易养殖,是适合我省推广的底层鱼种.

In order to change the traditional culture structure with silver carp and bighead carp in main cultivation in the district of Jiang- Huai, increase the cultivated proportiou of high quality fishes and raise the output as well economic benefits, then we carried on a studies on a series of cultivated techniques and biological characters for Allog- ynogenetic Crucian Carp (Carassius auratus gibelio) from 1984 to 1988, and found out some important parameters of a series of cultivated te- chniques for Allogynogenetic Crucian Carp by chief or mixed culti- vation in pond. The relative biological determination had proved that its growing speed was faster 0.44 times than that of white carp and faster 1.02-1.52 times than those of local carp. Allogynogenetic Cru- cian Carp had a lot of fine characters just as rich in nutrition, Wide feeding habits(omnivorous habits), well adaptability, less disease, easy cultivation and so on, then it should be suited to popularize as a fine bottom variety of fish in Anhui.
