Problems solved by technology

[0003] However, the traditional way of adding fortifiers is to attach the nutrient enhancer to the bait fish through an adhesive or directly insert the enhancer into the mouth or abdomen of the bait fish. The dosage and nutrients will be lost in the water, which will weaken the strengthening effect of broodstock

preparation example Construction

[0032] The present invention provides a preparation method of the nutrition enhancer capsule described in the above technical solution. The preparation method comprises: filling the nutrition enhancer into the determined capsule to make the nutrition enhancer capsule. The present invention does not have any limitation on the filling method, and the methods known to those skilled in the art can be adopted. In the present invention, it is preferred to use a mechanical filling method for filling.

[0033] The present invention provides the application of the nutrition enhancer described in the above technical solution in the cultivation of flounder.

[0034] In the present invention, the application preferably includes: feeding broodstock with the nutrient fortifier; the feeding preferably includes: stuffing the nutrient fortifier into the bait fish; feeding the broodstock with the obtained bait fish; the feeding The way of feeding is preferably to throw the correspondingly trea...

Embodiment 1

[0047] Raw material preparation for nutrition enhancer (parts by mass): 70 parts of Schizochytrium sp., 15 parts of lactic acid bacteria, 5 parts of multivitamin, 0.5 part of liver strengthening agent, and 9.5 parts of yeast.

[0048] ①Select broodstock of flounder with mature gonads weighing between 3kg and 5kg, with a male-to-female ratio of 1:1, and put them in a square cement cultivation pond for temporary breeding, and the temporary breeding density of broodstock is controlled at 2kg / m 2 up to 5kg / m 2 .

[0049] ② Select 0# edible capsules by calculation, fill each capsule with 0.5g nutritional enhancer, then stuff the capsules into the mouth of chilled bait fish (20g-30g per fish), and then feed them. The way of feeding is to put the correspondingly processed bait fish into the water in the breeding pond.

[0050] ③Clean the bottom of the pool and change the water once a day during the holding period.

[0051] ④ Accelerate the maturation of broodstock by gradually pro...

Abstract

The invention relates to the field of aquaculture, in particular to a nutrition fortifier capsule special for Paralichthys olivaceus and a preparation and application of the nutrition fortifier capsule. The nutrition fortifier capsule special for Paralichthys olivaceus is a filling capsule; the filling capsule includes a glutinous rice capsule and a nutrition fortifier filled in the glutinous ricecapsule; the nutrition fortifier includes the following components in parts by mass: 65-85 parts of schizochytrium, 8-25 parts of lactic acid bacteria, 3-10 parts of multivitamins, 0.5-2 parts of a liver strengthening agent, and 5-20 parts of saccharomycetes. By adopting the nutrition fortifier capsule special for Paralichthys olivaceus, the immunity and resistance of parent fish bodies can be enhanced, the quality of fertilized eggs produced by parent fish and the rate of hatching are effectively improved, and the deformity rate of fry is reduced.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a nutritional enhancer capsule for flounder and its preparation and application. Background technique [0002] Flounder (Paralichthys olivaceus) is one of the precious economic fishes and an important seawater aquaculture species in my country. In the process of flounder breeding, the nutrition of broodstock plays an important role in improving the spawning quantity, the quality of eggs and larvae, and the growth and survival of larvae. In the breeding process of artificial breeding, in order to produce healthy seedlings, it is particularly important to ensure the quality of gametes produced by broodstock. The cultivation of broodstock becomes the key point, and the health status of broodstock before reproduction directly affects the quality of the gametes produced by it. The nutrient enhancer can significantly improve the growth performance of aquatic organisms and enhance their imm...
