Embodiment 1
[0018] 1) Pretreatment of the holding pond: choose a freshwater pond with a salinity of 0.8-1.2‰ as the holding pond, bundle fresh willow branches with leaves into the bottom of the holding pond, and put 40- The proportion of 50kg fresh willow branches is placed; then in the holding pond, drop into water quality improver, described water quality improver consists of 5 parts of cellulase, 8 parts of protease, 25 parts of Bacillus subtilis, 15 parts of faecococcus, 7 parts of vitamin C, It is made by mixing 18 parts of fresh willow leaf powder, adding 2-5g of water quality improver for every 10-20 kg of fish;
[0019] 2) The natural perch seedlings with a body length of 1-2 cm caught from the northern sea area are put into the above-mentioned holding pond after being desalinated to a salinity of 4-7‰, and the stocking density of the holding pond is controlled at 1-15,000 per mu. Oxygenation by flushing water in holding pool;
[0020] 3) Start feeding zooplankton on the second d...

The invention belongs to the technical field of fishery and relates to a cultivation method of a sea bass fingerling holding pond. The method is characterized by including the steps of 1, pretreating the holding pond; 2, catching natural bass fingerlings 1-2cm long, from a northern sea area, performing desalting to 4-7%. of salinity 4-7%, putting the bass fingerlings in the holding pond, controlling stocking density of the holding pond to be 1-1.5 fingerlings per mu, and filling the holding pond with water frequently for oxygen increasing; 3, feeding the fingerlings with plankton from the second day of entry, and feeding the fingerlings with the plankton and fingerling feed from the third day; 4, feeding the fingerlings with the fingerling feed once a day, with 1-2g of the fingerling feed per 10-20kg of fingerlings, and putting the fishes growing to 4-6cm long into a large pond for thin cultivation, 20-30 days after cultivation. The method has the advantages that the holding pond is pretreated to improve water quality, ecological environment of cultivation water is quick remedied, diseases and sudden death of the fingerlings are effectively prevented, and the use of fish feed with fish disease control and treatment functions in feeding the fishes leads to further increase in survival rate, yield and quality of the bass fingerlings.
Description
technical field [0001] The invention belongs to the technical field of fishery, and in particular relates to a culture method for a temporary culture pond for sea bass fry. Background technique [0002] Bass likes to live in brackish and fresh water in estuaries, and can also live in fresh water. It is mainly distributed in the western Pacific Ocean, the coast of my country and the fresh water bodies leading to the sea. There are many in the East China Sea and Bohai Sea. It is ferocious and eats fish. It is the most common species. It is one of the economic fishes, and it is also a species for developing mariculture. Sea bass contains nutrients such as protein, fat, and carbohydrates, as well as vitamin B2, niacin, and trace amounts of vitamin B1, phosphorus, and iron, and has high edible and medicinal value. There are many methods of artificial breeding of perch, especially the breeding of seedlings is easily threatened by fish diseases, which affects its survival rate and ...
