哈尔滨市水产研究所从1986年以来开始研究以鲤为主的池塘养鱼高产综合技术。根据我国传统的池塘养鱼“八字精养法”,使其技术总结得更简便。为更多的养鱼者掌握,他们结合多年的驯化养鱼实践,认为池塘驯化养鱼的主要技术是:1.水质、2.饲料的营养、3.鱼种、4.防病,简称“水、种、饵、防”四字精养法。 一、水质: 池塘中水质保持良好水平的要素是充足的溶氧量和避免鱼本身代射产物积累过多。我们所做的试验表明,鲤鱼池的溶氧量,白天应保持在4mg/l以上,在4mg/l以下,鲤鱼的生长速度呈下降趋势。溶氧量过低不仅使鱼的生长受到抑制。饲料系数也将增大,鱼的抗病力下降,易感染疾病。其他鱼的驯化、如团头鲂白天应保持在5mg/l以上为宜,美 Harbin Institute of Fisheries since 1986 began to study the carp-based pond fish farming comprehensive technology. According to our traditional pond fish “character training method” to make the technology more concise. In order to master more fish farmers, they combined years of domesticated fish practice, that the main technology domestication of fish ponds are: 1. Water quality, 2. Feed nutrition, 3. Fish species, 4. Disease prevention, referred to as “ Water, species, bait, anti ”word intensive method. First, the water quality: Pond water quality to maintain a good level of elements is sufficient dissolved oxygen and avoid the fish itself, the accumulation of too many products. Our experiments show that the carp pond dissolved oxygen during the day should be maintained at 4mg / l or more, below 4mg / l, carp growth rate decreased. Dissolved oxygen is too low not only to inhibit the growth of fish. Feed factor will also increase, the resistance of fish decreased, susceptible to disease. Domestication of other fish, such as bream 鲂 should be kept at 5mg / l or more during the day, the United States
