饵料一般占养鱼生产成本50％左右,在当前饲料价格上扬,渔场经济效益不高的情况下,如能提高饵料报酬,降低饵料系数,对增加产量,提高效益都有十分重要意义,以下措施能有效地降低饵米系数。 1.合理混放密养鱼种 鱼种放养适宜,就能提高池鱼产量,降低饵料系数,混养密度过大,浮头频繁,影响鱼类摄食及消化吸收,饵料系数就高;混 The feed generally accounts for about 50% of the cost of fish farming. Under the circumstances that the current feed price is rising and the economic benefits of the fishery are not high, it is of great significance to increase the output and increase the profit if the feed rewards are raised and the feed efficiency is reduced. The following measures Can effectively reduce the bait coefficient. 1. Proper mixed stocking fish species stocking appropriate, can increase the production of fish ponds, reducing feed conversion coefficient, polyculture density is too large, frequent floating head, affecting fish intake and digestion and absorption, the feed coefficient is high;
