Description
Technical Field
The invention belongs to the technical field of aquaculture, and particularly relates to a feed for juvenile salmon of salmon in horse scotch and a preparation method thereof.
Background
Salmon (Oncorhynchus masou), salmonidae (Salmoniformes), salmon material (Salmonoidea), salmon genus (Oncorhynchus Suckley, 1861). Important economic fishes are rich and individual, have red and fatty meat, tender meat and delicious meat taste, are popular and loved by consumers, and are special fishes and main fishery objects along the coast of the northern Pacific Asia. It was only distributed in the Sublin river and the Turkey river, and occasionally found in the North and middle parts of the yellow sea. The subspecies are distributed abroad in the areas of Japan and Russia far east, such as Heilongjiang, Kancao peninsula and Korea. At present, the resources are in an imminent extinction state.
The salmon is migratory fish, and juvenile fish are divided into two kinds of geographical ecological groups of sea-lowering type and land-sealing type in the fresh water growth period. Land-sealed groups live in fresh water rivers for the whole life, do not fall into the migration of the sea, and become a rare biological characteristic in the salmon. Therefore, the method has wide freshwater aquaculture prospect.
The number of organism populations in salmon of the marshmallow salmon has decreased dramatically in recent years. In order to recover and protect germ plasm resources of the salmon, the fishing industry is changed into artificial propagation and breeding migratory type and land seal type populations, and artificial propagation releasing is carried out. Wild land-seal type young salmon of salmon ingests mainly larvae and adults of aquatic insects. Scholars at home and abroad have more biological researches on the sea-lowering type population, and have few researches on the land-sealing type population. In the prior art, common cold water fish compound feed is adopted to culture the juvenile salmon, and because the requirements of different types of fish on the nutritional components are different, the feed cannot completely meet and is suitable for the nutritional requirements of the juvenile salmon, so that the growth speed of the juvenile salmon is slow, and the culture cost is high; in addition, the utilization rate of the feed is not high, the environment pollution and the resource waste can be caused in the breeding process. The feed formula suitable for nutrient substances is a limiting factor for large-scale and ecological environment-friendly culture of the juvenile salmon of the salmon.
Therefore, a new technical solution is needed in the prior art to solve this problem.

The experiment is carried out in the period from 1 month 5 in 2020 to 28 days 8 in 2020, and the culture period is 120 days. In areas of Jilin, Yanbian, 29682and spring. The experimental fish is 1 winter-old young salmon artificially bred in 10 months in 2019, the weight of the experimental fish is 6.18 +/-0.52 g, 4500 fishes are randomly and averagely thrown into 15 circular running water culture ponds with the diameter of 4m, and 300 fishes of the young salmon are thrown into each culture pond. And (4) disinfecting the experimental tank by using chlorine dioxide before putting the experimental tank. The group is divided into an experiment 1 group, an experiment 2 group, an experiment 3 group, an experiment 4 group and a control group, each group is provided with 3 parallel experiments, and the feed prepared in the example 1, the example 2, the example 3 and the example 4 and the high-price salmon and trout compound feed sold in the market are respectively fed. The experimental period was 3 times per day, 6: 00, 12: 00, 18: 00 respectively. The daily bait feeding rate is 3-5%, and is adjusted according to the change of water temperature.
The water temperature is 9.21-12.6 ℃ on average, the pH value is 7.5-7.9, and the dissolved oxygen in the water is 9.26 mg/L.
The experimental data are presented as: mean ± standard deviation. Statistical data, analysis of variance and multiple comparisons were performed using Microsoft Excel 2007 and SPSS19 statistical software. The difference is extremely remarkable when the P < 0.01 is smaller than the difference is 0.05. The calculation formula is as follows:
(Wt-Wo)/t;
the weight gain rate is 100% × (Wt-Wo)/Wo;
specific growth rate is 100% × (LnWt-LnWo)/t;
feed factor ═ F/[ n (Wt-Wo) ];
wo and Wt are average body weights (g) at the beginning and the end of the experiment, t is the culture period time, and F is the food intake (g).
The results of the verification are shown in Table 1
TABLE 1 growth index and feed coefficient of experimental and control groups
Note: the differences between the mean values marked with different letters in the same line are significant (P < 0.05), and the differences between the mean values marked with the same letters are not significant (P > 0.05).
Results of the experiment
The feeding results of the groups of example 1, example 2, example 3 and example 4 under the same culture condition for 120 days show that the terminal weight, the daily gain, the weight gain rate, the specific growth rate, the survival rate and the feed coefficient are all significantly different (P < 0.05) at the end of the experiment under the condition that the initial weight is not significantly different compared with the control group, the growth speed is significantly higher than that of the control group, and the feed coefficient is significantly reduced. The invention is proved to have obvious effects on promoting the growth of the salmon and preventing the occurrence of common diseases; the feed coefficient is obviously lower than that of the control group, which shows that the feed conversion efficiency is obviously higher than that of the control group.
