As can be seen from Table 2, the dirty body ratio of embodiment 14 feed group, liver body are than minimum, and coefficient of condition is moderate, and build is the most desirable.And the dirty body ratio of commercial feed B group, liver body are than the highest, and build overfertilization, there is " pregnant " phenomenon.The dirty body ratio of commercial feed A group, liver body are lower, but its coefficient of condition is also low, and fish body is partially thin.
With reference to figure 1-3, in the pond waters of embodiment of throwing something and feeding 14 feed, PH stability is best, and between 7.1-7.7, in the fish pond of other two groups of feeds of throwing something and feeding, PH fluctuation is comparatively large, between 6.5-7.8, has especially arrived the cultivation later stage, the serious meta-acid of water body.Ammonia nitrogen and nitrite also have same trend, throw something and feed example 14 feed pond waters in ammonia nitrogen the highlyest only have 0.36mg/L to the cultivation later stage, and commercial feed A group and B group best result do not reach 0.71 and 0.66mg/L, same nitrite is also more than 2 times of embodiment 14.As can be seen here, example 14 groups of feeds of throwing something and feeding can reduce the water pollution degree in raw fish culture fish pond, are more conducive to the stability of water body, thus prevent disease to grow, improve the survival rate of raw fish.
From feed coefficient, survival rate, fish body build and the stable aspect analysis to breeding water body, compared with the present embodiment 14 feed and other two kinds of commercial feeds, there is clear superiority.
