原《湖南水产》1991年第二期介绍了《池底种稗培育鱼种技术》,是一种改良生态环境,提高鱼种成活率,增加经济效益的好办法。今年七月,我借鉴种稗培育鱼种的方法,在自己的鱼种池进行了一次试验.取得了比较理想的效果。很适合发花鱼种池采用。由于鱼苗摄食不完全,过分的投饵施肥,池底沉积大量淤泥、剥饵,未被完全吸收的肥料。如果直接用来培育春片,往往会造成泛塘水质老化,鱼种的疾病易发生,从而影响鱼种的成活率。此方法操作简单,主要做好以下几项工作: 1、干池。一般在6月下旬进行,将鱼池中鱼种过池暂养,将池底整平,开好排水沟。 2、插秧。事先多留一点晚稻秧田,播种时
The original “Hunan Fisheries” in 1991 the second phase of the introduction of “bottom barnyard breeding fish species technology” is a way to improve the ecological environment, improve the survival rate of fish species, increase economic benefits of a good way. In July of this year, I conducted a test in my own fish breeding pool using the method of breeding barnyard grass, and achieved satisfactory results. Very suitable for the use of fish pond species. Due to incomplete feeding of fry, excessive feeding and fertilization, deposition of a large amount of silt on the bottom of the pond, peeling bait, and incomplete absorption of fertilizer. If used directly to cultivate the spring piece, it will often result in the aging of the pan pond water, diseases of the fish species will easily occur, thus affecting the survival rate of the fish species. This method is simple, mainly do the following work: 1, dry pool. Generally carried out in late June, the fish ponds in the pool hold, the bottom leveling, open drain. 2, transplanting.
