Experimental example 1
The large yellow croaker artificially cultured by adopting the color-mixing compound feed is experimentally found in Fujiangningde. The experimental net cage adopts large frames, each large frame is provided with 6 small frames with the size of 3.3m multiplied by 6m, and the size of the large yellow croaker is about 180 g/fish.
The net cages are randomly divided into 5 groups, the 1 st group (blank group) is cultured by using ice fresh fish, the 2 nd group is cultured by using the compound feed of the embodiment 1, the 3 rd group is cultured by using the compound feed of the embodiment 2, the 4 th group is cultured by using the compound feed of the embodiment 3, and the 5 th group is cultured by using the compound feed of the comparative example 1. The feeding times are twice a day, the feeding is finished for about 1 hour, and the feeding time and the feeding amount are the same.
After 6 months of culture test, 30 fish with the same weight are randomly selected to measure the body height-body length ratio and the carotene content of the back, the abdomen and the lips, and the results are shown in the following table 1.
TABLE 1 cultivation test results

Figure BDA0003183683090000051
Compared with feeding iced fresh fish and reducing pigment group, the compound feed of the invention can obviously increase the body color of yellow croaker, which indicates that the yellow croaker has low capability of synthesizing carotenoid and needs to be obtained from the outside.
From the pigmentation at the back and abdomen of the test group, the glossiness of the large yellow croaker in the group 2 is better than that of other groups, and carotenoid is easy to accumulate on lips, which provides technical guidance for the compound feed imitating wild large yellow croaker. The strips of each test group are much better than those of group 1 in terms of height/length, which indicates that the strips of the large yellow croaker can be obviously changed by feeding the compound feed of the invention.
The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
