俗话说,清明到霜降,鱼类生长旺。做好这段时间的饲养管理十分重要。首先,要满足各种鱼类的饵肥需要。由于5—9月水温处于20℃—30℃,正是各种鱼类大量摄食、迅速生长的时期。对草食性鱼类必须供给量足质优(鲜嫩、适口、无毒)的饵料,不可时饥时饱。此时期草鱼的日平均吃食量:嫩旱草约为其体重的20%—30%;水草约为其体重的80%—100%。投喂精料量约占吃食总量的3%—5%,每次的投饵量以投后3—4小时吃完为佳。下午投饵不能太晚(2—4时),否则鱼饱食过夜,耗氧量大,浮头时易死亡,特别是到了“双抢”繁忙季节,更应加强投饵管理。对滤食性鱼类应根据季节、水质、天 As the saying goes, clear to frost, fish growth flourishing. Good management of this period of feeding is very important. First, to meet the bait needs of all kinds of fish. As the May-September water temperature at 20 ℃ -30 ℃, it is a large number of various fish feeding, rapid growth period. For herbivorous fish must supply sufficient quality (fresh, palatable, non-toxic) of the food, when not enough hunger. The average daily feed intake of grass carp during this period: tender dry grass is about 20% -30% of its weight; aquatic grass is about 80% -100% of its weight. Feeding fine feed accounts for about 3% -5% of the total amount of food, feeding each time to vote 3-4 hours after eating better. In the afternoon, the feeding should not be too late (2-4 o’clock), otherwise the fish will have to eat overnight, the consumption of oxygen will be high, and the floating head may easily die. Especially in the busy season of “double grab”, bait management should be strengthened. The filter-feeding fish should be based on the season, water quality, days
