池塘驯养大鳞鲃某些生物学特性研究

Some biological characteristics of Barbus capito bred in ponds

记述了大鳞鲃野生种和人工驯养种在池塘养殖条件下的某些生物学特性,如该鱼的栖息习性、生长、食性及繁殖特性等,研究了人工繁殖仔鱼和幼鱼的生长状况以及对盐碱的耐受性,结果表明:鱼苗对NaCl耐盐量为10 g/L,对NaHCO3碱度的耐受性为1 g/L(11.60 mmol/L),鱼苗适宜在淡水和半咸水中生长.

Some biological characteristics of wild and domestic species of Barhus capito are studied, including habitation, living environmental habits, feeding pattern and propagation characteristics. Both growth and abilities of and fingerlings of artificial propagation in resisting salinity and bicarbonate alkalinity are studied respectively. The tolerance of salinity and bicarbonate alkalinily for larva fishes was 10 g/L and 11.60 mmol/L respectively, and Barhus capito grows well both in fresh water and brackish water.
