Effect example 1
Test selects original body mass to be that 200g large yellow croaker cultivates in 18 mouthfuls of net cages (2m × 2m × 2m), be divided into 6 groups at random, often organize 3 mouthfuls, culturing time is year June in September, 2014 to 2015, and period throws something and feeds the different mixed feed of embodiment 1 ~ 5 and the mixed feed of comparative example respectively.From throwing something and feeding, throw something and feed continuously respectively and execute the feed 14 days of example 1 ~ 5, monthly throw something and feed continuously the beginning of the month 7 days later, other times are thrown something and fed the mixed feed of comparative example, and the mixed feed group of comparative example of throwing something and feeding is thrown something and fed the mixed feed of comparative example all the time.Test is carried out in Ningde City Jiaocheng District San Dou town Shanghai Ocean University and Nong Hao company Collaborative experiment base, Shanghai.Each outcome record is in table 1.
The mixed feed group of table 1 embodiment 1 ~ 5 feed group and comparative example is on the impact of large yellow croaker growth and survival rate
| Comparative example 1 | Embodiment 1 | Embodiment 2 | Embodiment 3 | Embodiment 4 | Embodiment 5 | |
| Original body mass/g | 200 | 200 | 200 | 200 | 200 | 200 |
| Whole opisthosoma weight/g | 610 | 690 | 616 | 674 | 681 | 667 |
| Survival rate/% | 81 | 93 | 95 | 91 | 94 | 91 |
| Rate of body weight gain/% | 205 | 245 | 233 | 237 | 240.5 | 233.5 |
From table 1, the rate of body weight gain of embodiment of throwing something and feeding 1 ~ 5 feed large yellow croaker exceeds more than 28% than the mixed feed group of comparative example of throwing something and feeding, and survival rate is high by more than 10%.Also observe in breeding process: the mixed feed group large yellow croaker of comparative example of throwing something and feeding is much dead because of difficult labour in the egg-laying season, and throws something and feeds embodiment 1 ~ 5 feed group all without discovery.The cultivation sampling statistics result of test also shows: the throw something and feed genital gland indices of mixed feed group large yellow croaker of comparative example of egg-laying season is 20.4; And the genital gland indices of embodiment 1 ~ 5 feed large yellow croaker of throwing something and feeding is 14.8, significantly lower than comparative example group.Wherein representated by genital gland indices is the development degree of sexual gland, and more partial gigantism degree is higher for numeral, and arrive certain numeral egg maturation, fish is about to lay eggs.
Conclusion: contrasted from the use of the mixed feed of above-described embodiment feed and comparative example, the functional feed of suppression large yellow croaker gonad development provided by the invention, significantly can suppress growing of female large yellow croaker sexual gland and egg cell, promote that the body weight of large yellow croaker increases.
Be to be understood that example as herein described and embodiment only in order to illustrate, those skilled in the art can make various amendment or change according to it, when not departing from Spirit Essence of the present invention, all belong to protection scope of the present invention.
