Embodiment 1

[0019] A method for promoting the balanced growth and immune strengthening of gifu tilapia fingerlings, comprising the following steps:

[0020] The first step, seed cultivation: build a plurality of net cages in the pond, the length × width × height of the net cages is 1.8m × 2.0m × 1.2m, adopt microporous circulation to increase oxygen in the net cages, and each net A feed table is placed in the middle of the box, and 800 to 2,000 fish are placed in each cage according to the size of the fish;

[0021] Step 2, basic ration preparation: the size of the seedlings is 1.5cm to 5.0cm, the protein content in the basic ration is 38%, and the fat content is 8%; the size of the seedlings is higher than 5cm, and the protein content in the basal ration is 33 %, fat content is 8%; Fat comprises fish oil, soybean oil and olive oil in the basal diet, and by volume fish oil: soybean oil: olive oil is the ratio mixing of 4:3:1;

[0022] The 3rd step, the preparation of compound Chinese her...

Abstract

The invention discloses a method for prompting balanced growth and immune fortification of oreochromis niloticus fries. The method comprises following steps of seedling culture, basic diary food preparation, composite traditional Chinese medicine preparations and seedlings feeding. Compared with the prior art, the method for prompting balanced growth and immune fortification of oreochromis niloticus fries has following advantages: (1) the method is capable of effectively prompting balanced growth of oreochromis niloticus fries so that uniformization of fries; (2) basic diary food in the method is prepared through proper proteins, fat ratio and traditional Chinese medicine ratio such that immunity stress response capabilities of oreochromis niloticus fries are improved; (3) basic diary food and traditional Chinese medicine belong to green feeds and satisfy the safety standard and cause no pollution on fish and water so that the healthy breeding requirement is satisfied.

Description

technical field [0001] The invention belongs to the field of aquaculture, relates to aquaculture management and feed feeding technology, in particular to a method for promoting the balanced growth and immune strengthening of gifu tilapia fry. Background technique [0002] Gifu tilapia, as the main cultured fish in the southern provinces of my country, has the advantages of fast growth and wide adaptability. Gifu tilapia is an omnivorous fish. When the individual size is irregular, the larger tilapia will grab food fiercely, and the smaller-sized fish will often not be able to grab food, which will cause more and more differentiation in size. At the same time, when the bait is lacking, the Gifu tilapia cannibalize each other, and the large-sized tilapia will swallow the small-sized tilapia, thereby affecting the survival rate of the fish species. [0003] Streptococcus disease in tilapia has become a bottleneck restricting the development of tilapia industry. Improving the i...
