| Comparative example 5 | 85.9 | 4.28±0.19 | 0.78 |
The results show that the survival rate of the Lutjanus erythropterus fries obtained by the fry breeding of the embodiment 1-3 is high, the size of the fries is large, and the coefficient of variation is obviously reduced. Wherein, compared with the example 3, the survival rate and the specification of the fries of the comparative examples 1 to 5 are both obviously reduced, and the variation coefficient is increased, which shows that the breeding condition of the invention is adopted to greatly promote the benign growth of the fries of the Lutjanus erythropterus.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
