Abstract

The invention relates to an artificial tilapia mossambica breeding technology which comprises the following steps: clearing and disinfecting a fishpond; cultivating the water quality by using organic fertilizers; putting high-quality parent fish in a certain male-female proportion; controlling the water temperature in the breeding pond and promoting the female fish to lay eggs; adjusting the water temperature to promote the natural incubation and produce fry; taking out the fry and putting in a pond with better water quality for breeding; and putting plant and animal baits through a mixed breeding manner to promote the growth. According to the artificial tilapia mossambica breeding technology, the output and the benefit of the tilapia mossambica can be effectively improved and the development of the tilapia mossambica breeding industry can be pushed.

Description

A kind of Tilapia mossambica artificial culture technology
Technical field
The present invention relates to a kind of Tilapia mossambica artificial culture technology, particularly relate to and scale can cultivate rapidly a large amount of Tilapia mossambica, increase economic efficiency.
Background technology
Tilapia mossambica originates in Africa, for net-rope, Perciformes, eel Gyrinocheilidae, Tilapia mossambica belong to.It wishes by large-scale cultivation after introducing China, and adjustment fishery constitution, helps farmer richness.So a lot of people does not understand the economic benefit of Tilapia mossambica, and artificial culture technology does not obtain further investigation and large-scale popularization.How by Tilapia mossambica is carried out artificial propagation, ensure the output of its seed, and ensure making full use of of feed by raising together with, increase economic efficiency, become the Main way of research.
Summary of the invention
The object of the present invention is to provide a kind of more effective Tilapia mossambica artificial propagation techniques, improve reproduction rate, the increase yield of Tilapia mossambica.
The technical scheme that the present invention solves the problems of the technologies described above is as follows: a kind of Tilapia mossambica artificial culture technology, comprises the following steps:
Arrange fishpond with lime disinfection;
After injecting new water, organic fertilizer is to cultivate water quality, puts parent population in a suitable place to breed after 1 week;
Parent population is thrown in when water temperature 18 DEG C, bait throwing in twice every day, promotes that Gunther parent fish spawning and the hatching of employing nature are sent out and hatches, calculate the Gunther parent fish spawning date and also collect seedling in time, carrying out seed rearing;
After fry grows to more than 3cm, go out the pool and carry out food fish cultivation;
Marketable fish poud can adopt the mode of raising together with, and ensures output.
On the basis of technique scheme, the present invention can also do following improvement:
Breeding pool area is moderate, about depth of water 1.5m; Arrange behind fishpond, to splash 2000kg lime disinfection by per hectare, the new water of injection after 2 weeks, and organic fertilizer 2000kg/ hectare is to cultivate water quality; Parent population can be put in a suitable place to breed after 1 week; The breeding mouth of a river, pond adopts diagonal way to arrange, and water inlet is higher than the pond water surface, and discharge outlet is consistent with water surface elevation, and gauze seals, and prevents the natural enemy harm such as snake, the frog, mouse.
The concrete grammar of further described parent population selection and input is as follows:
Parent population selects about 200g same kind Tilapia mossambica, build is rectified, physique is healthy and strong, without sick and wounded, fin is complete; Female-male proportion is 3:1, during water temperature more than 18 DEG C, can put in a suitable place to breed; Breeding density is per hectare 4000 tail.
The concrete grammar of further described promotion parent population breeding is as follows:
Breeding keeps water temperature 25 ± 5 DEG C in pond, and stimulate milter to dig nest, raun lays eggs, pairing.
Further described natural hatching method concrete grammar is as follows:
Water temperature remains on 25-30 DEG C, and flow velocity is more slow, and namely 5d completes, and juvenile fish will leave parent when yolk sac disappears.
The cultivation concrete grammar of further described fry is as follows:
Another water quality of the seed hatched taking-up immigration better bred in pond and cultivate, density keeps 1,000,000 fishes/ha, cultivates plankton and ingests for it, and throw something and feed with soya-bean milk growth promoting effects, can grow to more than 3cm, go out the pool after 15d, move into culturing pool to apply fertilizer.
It is as follows that further described juvenile fish raises together with concrete grammar:
Based on Tilapia mossambica, density ensures 35000 fishes/ha, raises together with four large Chinese carps, silver carp (specification 250g/ tail) 3750 tails, flathead (specification 250g/ tail) 600 tails, grass carp (specification 500g/ tail) 750 tails, carp (specification 250g/ tail) 150 tails; Per hectare organic fertilizer 1500kg, because Tilapia mossambica is omnivorous, bait throwing in comprises vegetalitas and animality two kinds, mainly contains rice bran, wheat bran, soya-bean cake, bean dregs, groundnut cake, rapeseed cake, vinasse, silkworm chrysalis, bean powder, wolffia arrhiza etc., throw something and feed every day 3 times, more than average weight 800g can fish for; As need fish crop be increased, adjustable feed and impressions.
The invention has the beneficial effects as follows:
Parent population fish brood amount is high, and hatching m is simple, and incubation rate is high, and hatching speed is fast; Fry growth is grown neat, and survival rate is high; It is high that juvenile fish raises together with output, high financial profit.
Embodiment
Build 667m 2breeding farm, 1 hectare of rearing pool, ensure the water requirement of plant, water source is pollution-free.Is sterilized in breeding farm, fertilising.Keep depth of water 1m, water temperature more than 20 DEG C.Throw in about 300g parent population, male and female are pressed 3:1 and are thrown in, about 4000 tails.After laying eggs, treat that juvenile fish naturally hatches in female lymphogranuloma inguinale, keep water temperature to be no more than 25-20 DEG C.Seed is taken into after can moving about in another breeding pond and feeds, and after 15 days, seedling should grow to moon an about 3cm, moves in rearing pool and raises together with.According to actual conditions adjustment feed and impressions.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
