The average water temperature for cultivation is 27.8+/-0.8 ℃, aeration is continuously carried out for 24 hours, dissolved oxygen is kept above 6mg/L, pH is 7.5-8.0, the feed is fed for 2 times per day (feeding time is 7:00 and 16:00 respectively), and feeding amount is the same. Adding or replacing proper amount of water for cultivation at regular time, and fishing out dead fish in time and weighing. After 15 days of cultivation, the weight of bighead carp which ingests different feed groups is measured respectively, the weight gain rate of each group is calculated, and the data are the average value of all the values.
The average values of initial weight, final weight and weight gain of the fish cultured in each culture pond are shown in Table 2.
TABLE 2
| Test set | Initial weight g | Final weight g | Weight gain percentage% |
| Feed 1 | 25.2 | 82.8 | 228.5714 |
| Feed 2 | 25.6 | 85.3 | 233.2031 |
| Feed 3 | 25.1 | 88.2 | 251.3944 |
| Feed 4 | 25.0 | 79.4 | 217.6 |
The weight gain rate is as follows: [ (final weight-initial weight)/initial weight ]. Times.100%.
Table 2 shows that the fish feed prepared by the application can improve the palatability of the feed and induce fish to ingest the feed, thereby increasing the ingestion of fish, providing nutrients for fish and promoting the growth of fish.
The application adopts alfalfa, bean pulp, wiggler freeze-dried powder and rapeseed meal, wherein alfalfa crude protein is an essential nutrient substance for livestock and poultry, and crude fat is a main source of heat energy, so that the palatability of the feed can be improved. NDF and ADF in alfalfa are important feed nutrition indexes for ensuring milk fat percentage, NDF determines feeding rate, ADF determines digestibility, NDF content in alfalfa is 57.0-34.3%, ADF content in alfalfa is 51.4-38.8%, and alfalfa seeds contain various microelements such as calcium, phosphorus and the like. Meanwhile, the wiggler freeze-dried powder is added to provide and supplement polyunsaturated fatty acid required by the growth of freshwater fish, so that the original cost is effectively reduced economically.
Meanwhile, the wiggler can be used as a live feed for fish culture, the wiggler is fast to reproduce and has high nutritive value, and the dry matter of the wiggler is tested by experiments to contain 62.6% of crude protein and 25.3% of crude fat, so that the wiggler is an initial feed for a plurality of aquatic animals in the fries, and is a high-quality feed for fishes such as salmon, sturgeon, mandarin fish, carp, crucian, loach, giant salamander, yellow and the like. The cultivated seeds can provide long-term stable high-quality animal feed for cultivated aquatic products, reduce the cultivation cost and improve the cultivation benefit and the cultivation quality. With the rapid development of the famous and excellent aquatic product breeding industry, animal baits such as child larvae and the like are more and more favored by vast breeders. The cultivation of the larvae has stable yield and high yield, the average cultivation period per square meter can cultivate about 2 kg of fresh larvae, the total production period per mu can reach 1000-1300 kg, the production value per mu can reach 2-2.6 ten thousand yuan according to the minimum price of fresh and alive baits for young fish in the current market per kg of the larvae, and only the wiggles can obtain 1.5-2.0 ten thousand yuan.
The alfalfa smell has better attraction to fish, and is rich in substances of natural active ingredients such as small molecular amino acids, peptides, nucleotides, vitamins and the like. The wheat germ peptide contains abundant active micromolecular peptide and free nucleotide, can obviously improve the oxidation resistance of grass carp meat, and increases the content of flavor substances (nucleotide) in the fish meat, so that the meat quality is more delicious.
The above description is only of the preferred embodiments of the present application and is not intended to limit the present application, but various modifications and variations can be made to the present application by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the protection scope of the present application.
