Problems solved by technology
Due to the large water body and stable water quality, this method is easy to cultivate fry, but because it is outdoors, it is greatly affected by the weather, and it is easy to encounter bad weather such as sudden and large low temperature, high temperature, large temperature difference between morning and evening, continuous heavy rain, etc. The other is the method of raising seedlings in indoor cement ponds. This method is also to cultivate basic baits such as unicellular algae, rotifers, and protozoa in indoor cement ponds, and then put the hatched fry into fertile water. Cultivate in a cement pond, adjust the water quality according to the water co

Example Embodiment
[0031] Example 1
[0032] According to the method disclosed in the present invention, the following operations are performed:
[0033] The grouper breeding method includes the following steps:
[0034] 1) Environmental conditions for nursery
[0035] 1.1) Cement pool
[0036] Several square cement pools with an area of 4 square meters, the bottom and wall of the cement pool are smooth, and the water depth is 60cm. In each of the cement pools, 5 irregular cement blocks are placed, and 5 blocks of 20cm are placed on the water surface* For the 30cm plastic board, 6 air stones are hung at the bottom of each cement pool to supply oxygen. Among them, the above parameters are only the data in this embodiment. According to the actual site and other conditions, it can also be adjusted accordingly. Can be implemented;
[0037] 1.2) Nursery environment
[0038] Dissolved oxygen is 5mg / L, PH value is 7.8-8.2, specific gravity of water is 1.020-1.022, water temperature is 26-32℃, light intensity i...

Abstract
The invention provides a grouper fry breeding method. The grouper fry breeding method adopts clean water to breed fries and includes steps of adding cement blocks and plastic plates with holes into a cement tank as shelters of the fries, so as to protect the fries from being scared by clear water, and culturing monodus subterraneus and rotifera as baits in the other water tanks, so as to prevent water quality in the cement tank from eutrophication and deterioration. The problem about baits can be solved by feeding. In addition, indoor fry breeding is unaffected by weather, the clear water contains few algae, organic matters and microorganisms, water quality is not easy to change, and with reasonably using photosynthetic bacteria, water quality is relatively easy to control. Accordingly, the grouper fry breeding method has the advantages of stability in fry breeding technology and high fry survival rate.
Description
technical field [0001] The invention relates to the field of animal and plant cultivation, in particular to a grouper breeding method. Background technique [0002] Grouper belongs to Perciformes, rich in nutrition, tender and white meat, similar to chicken, known as "sea chicken". At present, there are more than a dozen species of grouper that have been artificially bred, and some of them have reached the production scale. Fish, oblique-banded grouper, brown-spotted grouper, pearl gentian, saddle-banded grouper and eastern star grouper, in the artificial breeding process of grouper, water quality is critical, if the water quality deteriorates, toxic substances accumulate, or Changes in water quality will lead to seedling failure. The water quality deteriorates, the toxicity accumulates, and the fish fry will be poisoned and die; the algae grows too fast or suddenly decays, the pH value of the water body will change greatly, ammonia nitrogen, nitrite, etc. will increase, ca...
