There are many unreasonable places in the existing culture management of tilapia culture, such as the quality control and management of the culture water in fish ponds, feeding formula, feeding method and fry stocking, etc., especially with the price of feed It is constantly rising and often pollutes the water body in the process of feeding feed, which makes it difficult to guarantee the quality of the aquaculture water body, which is not conducive to the nitrification of nitrifying bacteria. Its conversion efficiency of ammonia is low, and the degradation rate of ammonia gas is slow. The purification time is long, especially in the breeding process of tilapia juveniles. Tilapia juveniles are extremely easy to die due to excessive ammonia gas in the water, which greatly reduces their survival rate and makes it impossible to carry out high-density breeding. Farming, unable to supply sufficient nutrition and environmental conditions for juvenile fish, low yield, high cost of breeding and low quality

Embodiment 1
[0054] Embodiment 1-a kind of cultivation method of the semi-closed circulating water of tilapia larvae, comprises the steps:
[0055] (1) Design nutrient solution: Prepare nutrient solution according to the mass percentage of the following components: 60% ammonium sulfate, 8% calcium hydrogen phosphate, 8% potassium dihydrogen phosphate, 8% sodium acetate, 0.5% vitamin premix, Enzyme preparation 0.35%, stabilizer 2%, mineral salt 1%, trace element mixed preparation 2%, tea polyphenol 1.2%, Cynomorium 2%, Radix Paeoniae Alba 0.8%, yeast 1.2%, amino acid 1.1%, maltose 3.5% and sodium alginate 0.35%;
[0056] Wherein, the preparation method of the nutrient solution comprises the following steps: firstly add water to dissolve ammonium sulfate, calcium hydrogen sulfate, potassium dihydrogen sulfate, sodium acetate and mineral salt according to the proportion, and then mix them in a container to obtain a mixed solution; The obtained mixed solution was heated to 60°C to dissolve al...
Embodiment 2
[0061] Embodiment 2-a kind of cultural method of the semi-closed circulating water of tilapia larvae, comprises the steps:
[0062](1) Design nutrient solution: Prepare nutrient solution according to the mass percentage of the following components: 75% ammonium sulfate, 4% calcium hydrogen phosphate, 4% potassium dihydrogen phosphate, 3% sodium acetate, 0.1% vitamin premix, enzyme Preparation 0.15%, stabilizer 2%-5%, mineral salt 1%, trace element mixed preparation 2.6%, tea polyphenol 1%, Cynomorium 1.5%, Radix Paeoniae Alba 0.5%, yeast 0.5%, amino acid 3%, maltose 1.5% % and sodium alginate 0.15%;
[0063] (2) Fish pond water body design: when the circulating water system in the breeding process is in operation, set the flow velocity, water temperature, water body exchange rate, dissolved oxygen and pH value of the breeding water body, wherein the flow velocity of the breeding water body is 0.6m / s; the water temperature is -31°C, and the maximum temperature difference of t...

Abstract
Provided are a method and system for breeding oreochromis mossambicus larvae with semi-enclosed circulating water. The method comprises the following steps that (1) a nutrient solution is prepared from 60-75% of ammonium sulfate, 4-8% of calcium hydrophosphate, 4-8% of monopotassium phosphate, 3-8% of sodium acetate, 0.1-0.5% of vitamin premix, 0.15-0.35% of zymin, 2-5% of stabilizer, 1-2% of mineral salt, 2-4% of microelement mixed preparation, 1-1.2% of tea polyphenol, 1.5-2% of herba cynomorii, 0.5-0.8% of radix paeoniae alba, 0.5-1.2% of yeast, 1-3% of amino acid, 1.5-3.5% of maltose and 0.15-0.3% of sodium alga acid; (2) the water body of a fishpond is designed, and microorganism preparations and the nutrient solution are regularly thrown into the fishpond; (3) fish fry is stocked; (4) feeding and management are carried out; (5) the water body of the fishpond management is carried out; according to the method and system for breeding the oreochromis mossambicus larvae with the semi-enclosed circulating water, through the design and preparation of a new nutrient solution formula and combined with parameter setting of the aquaculture water body, fish fry stocking, fish bait feeding formula, feeding mode and fishpond management, and it is realized that oreochromis mossambicus products with fewer diseases, high survival rate and good meat are cultivated.
Description
technical field [0001] The invention relates to the technical field of aquaculture, in particular to a method for cultivating juvenile tilapia in semi-closed circulating water and a system thereof. Background technique [0002] Aquaculture is the production activity of breeding, cultivating and harvesting aquatic animals and plants under human control. It generally includes the whole process of growing aquatic products from seedlings under artificial breeding management. There are many unreasonable places in the existing culture management of tilapia culture, such as the quality control and management of the culture water in fish ponds, feeding formula, feeding method and fry stocking, etc., especially with the price of feed It is constantly rising and often pollutes the water body in the process of feeding feed, which makes it difficult to guarantee the quality of the aquaculture water body, which is not conducive to the nitrification of nitrifying bacteria. Its conversion...
