Problems solved by technology

However, due to the constraints of factors such as geographical location and climate, the artificial breeding of anchovies under normal temperature conditions in this area can only be carried out in the first ten days of May, which affects the growth period of the year and prolongs the breeding cycle for growing into the market. It is not conducive to the improvement of production and efficiency; and the seedlings introduced from the south, due to long-term breeding and do not pay attention to the purification and rejuvenation of germplasm, coupled with the influence of climatic conditions, transportation and other factors, the risk of breeding is getting higher and higher , has seriously affected the healthy and rapid development of the mandarin fish aquaculture industry
Existing single-type fish fertilizers and compound-type fish fertilizers also have a common shortcoming, that is, they cannot kill harmful bacteria and insects, so they lack the effect of effectively preventing and controlling fish diseases
The content of beneficial bacteria in the fish pond can be increased through microbial compound fish fertilizer, and the occurrence of fish diseases can be effectively reduced. At present, there is no report on the method dedicated to cultivating sweet-scented osmanthus fish with nano-scale slow-release feed

preparation example Construction

[0028] The preparation method of described nano sustained-release carrier is:

[0029] (1) The silicon hydroxyapatite, attapulgite, hydrotalcite, montmorillonite, titanium dioxide, calcite, kaolin according to 35-45: 10-15: 10-15: 8-10: 8-10: 7-8 : 5-7 parts by mass are mixed, added to a mixed solution of 230 parts of dimethyl sulfoxide (DMSO) and 50 parts of methanol, stirred at 65°C for 60 hours, filtered, and washed with hot ethanol at a temperature of 60°C for 3 Remove excess dimethyl sulfoxide (DMSO) once, put it into a vacuum drying oven, dry at 60°C for 24 hours, grind and sieve to obtain a primary modified compound;

[0030] (2) Mix 1 part of primary modified compound, 15 parts of potassium acetate and 25 parts of distilled water, stir at 50°C for more than 10 hours, and disperse at 30°C for 3.5 hours under the condition of ultrasonic electric power 350W, and then in Disperse for 4 hours under the condition of ultrasonic electric power 250W. Filter, wash with distill...

Embodiment 2

[0035] The preparation method is the same as in Example 1.

[0036] In the sweet-scented osmanthus fish juvenile stage of growth, fish out, divide and raise in the middle of five pools, every pond 500, in four pools, throw in respectively the microbial sweet-scented osmanthus manure fertilizer of the embodiment of the present invention 1 and Ordinary sweet-scented osmanthus fish fertilizer (control 1, produced by Beijing Century Ames Biotechnology Co., Ltd.), the other tank was not fed with sweet-scented osmanthus fish fertilizer (control 2), but the same amount of ordinary fish food was put in, and the rest were fed the same amount. The culture environment is the same, after 2-4 months of breeding, comparing its yield and the growth of sweet-scented osmanthus fish, the nano slow-release additive has good biocompatibility and gastrointestinal mucosal affinity, so that each group loaded with it can It has a controlled release effect, and the drug loading and adsorption capacity...

Abstract

A method for using nanometer slow release feed to breed mandarin fish includes: building a pond which has a sandy bottom with 15cm of sludge, is more than 1.5m in water depth, convenient in drainage and irrigation and good in water quality, and has no waste water inflow; allowing the water temperature to be 25-29 DEG C which is most appropriate growth water temperature in artificial breeding; in winter and spring, fishing up robust parent fish without surface damage from the breeding pond to breed in a pond of a greenhouse and using the same for artificial breeding, and placing the breeding parent fish of the parent fish into the pond of the greenhouse; feeding four times each day during breeding, calculating feeding amount according to 20-50% of fish weight, feeding sufficiently to avoid feed competition, and flexibly control the feeding amount according weather conditions. By adding the composite microorganism feed of the method, fast growth of mandarin fish can be promoted, EPA content is increased, disease is reduced, mandarin fish death caused by diseases is reduced, beneficial microorganisms in water are increased, and final quality of mandarin fish is improved.

Description

technical field [0001] The invention relates to an aquaculture method, in particular to a method for cultivating sweet-scented osmanthus fish with nano slow-release feed. Background technique [0002] Mandarin fish (Siniperca chuatsi), also known as sweet-scented osmanthus fish and seasonal flower fish, belongs to Perciformes, Perciformes, Siniperca, and Siniperca genus. Mandarin fish is shaped like a perch in Songjiang River, with thorns on its wings. It is a rare freshwater economically farmed fish in my country. It has delicious meat, rich nutrition, high protein and various amino acids, and has medicinal functions. It has high economic value. In the Qing Dynasty, Zhang Zhihe had a poem of "peach blossoms and flowing water with mandarin fish fat", which is favored by consumers and has a broad market prospect. At the same time, with the need for species renewal and structural adjustment in the aquaculture industry, mandarin fish farming as a special aquatic product has als...
