Abstract
A pond watercress planting type grass carp high-yielding breeding method comprises pond construction, pond disinfection, grass carp fingerling breeding, watercress planting, feed selection, feeding method, watercress fertilization, planting and breeding management and disease control. According to the pond watercress planting type grass carp high-yielding breeding method, a large number of feed is fed in the process of high-density grass carp breeding, the quality of the water is corrupted, the eutrophication of a water body is produced, the nitrogen, the phosphorus and the potassium in the eutrophic water body can be absorbed by the watercress, and accordingly the water body is purified and the effective development space is provided for the high-yielding breeding of the grass carp; meanwhile the watercress which is high in nutritional value is harvested and part of the watercress can provide the feed for the grass carp during harvest; the operation is simple, the management is convenient, and the economic benefits are good.
Description
Technical field
The present invention relates to aquaculture pattern technology field, particularly a kind of pond method of watercress high yielding culture grass carp of planting.
Background technology
Grass carp: English name: Grass carp, be commonly called as careless grass carp, ctenopharyngodon idellus, grass carp, charlatan, inhabit the rivers and lakes of flat area, general happiness occupy middle lower floor and many pasture and water of offshore region of water.Property active, swimming rapidly, hunts in packs, and is typical herbivorous fishes.Because feeding habits are simple, feed source is extensive, and growth rapidly, and output is high, is often used as the main cultivation object in pond culture and lake, reservoir, river course.After artificial induced spawning in 1958, the success of fertilization and hatching technology, fry, fingerling source easily, have become the main intensive culture object of China, are one of four large Chinese carps of China's freshwater aquiculture.Together with often raising together with silver carp, bighead, drop into green grass and raise grass carp, and be retained in feed and the grass carp effluent in water, decompose by fermentation, for bacterial reproduction provides adapt circumstance, and then turn out plankton, bacterium and plankton are again as the feed of silver carp, flathead.In recent years, culturist solves according to the feed problem of this specific character of grass carp and grass carp, find out multiple breeding way as 80:20 pond high yielding culture, cage culture, reservoir, lake culture, particularly pond high yielding culture, the feed of throwing something and feeding has in large quantities caused breeding water body severe contamination, has destroyed breeding water body environment, also cause disease to take place frequently, thereby occur the dead fish phenomenon of large area in cultivation, serious contusion culturist cultivates enthusiasm, restrict grass carp cultivation development.Therefore, how to provide a kind of comprehensive ecological cultivation, reduce disease and occur, the culture model of win-win progress, has become the new problem that numerous scientific workers and raiser explore.
Summary of the invention
For above-mentioned situation, the object of the invention is just to provide a kind of method that watercress high yielding culture grass carp is planted in pond.
For achieving the above object, the technical solution used in the present invention is: it is characterized in that being made up of following steps:
1, pond is built: have abundant water resources, irrigation and drainage are convenient, pollution-free, the depth of water is at 1.5～2 meters, area is 10-20 mu.
2, pond disinfection: before fry is put in a suitable place to breed 10～15 days with bleaching powder 7～10,000 gram/acre, the band water sterilization of cleaning up the pond, or with 75,000 grams/acre of lime water full pool spilling heads.
3, careless fingerling stocking: around the Spring Festival, water temperature is thrown in the time of 6 degrees Celsius.Mu is put grass carp 1000 tails, and specification is 350～400 grams/fish; Bighead 200 tails, specification is 150～200 grams/fish; Crucian 200 tails, specification is 50 grams/fish.Put front use 4% common salt aqueous solution dipping bath sterilization 15 minutes in a suitable place to breed.
4, watercress is planted: in high yielding culture pond, adopt the easy floating bed watercress of planting, the floating bed of the watercress of planting is fixed in pond with rope, and the watercress area of planting accounts for 25% of pond area.
5, Feed selection: the grains dedicated feed of grass carp of selecting protein content 28%～30%.
6, feeding method: cultivation is thrown something and fed by 2%～3% of fish body gross weight in pond early stage, and the later stage is 5%～6%, throws something and feeds every day twice.
7, the fertilising of watercress: the pond watercress of planting, because watercress can absorb nitrogen, phosphorus, the potassium in pond water, can meet its growth, can execute if desired some bio-fertilizers.
8, breeding management: for high density culture pond, be mainly the water quality that keeps good, stable, the general pool of emphasis oxygen deficit proof.Annotate new water, open aerator in good time.
9, disease control: the policy of adhering to " put prevention first, anti-overweighting controlled ".While patrolling the pool, as found grass carp cluster and fish body blackout, continuous 2～3 days full pool spilling head 1 mg/litre bleaching powder; On watercress dish leaf, there is aphid, spray with biopesticide.
Beneficial effect of the present invention: the present invention is a kind of method that watercress high yielding culture grass carp is planted in pond, make full use of the feed of throwing something and feeding in a large number in high density grass carp breeding process, ruin water quality, there is water eutrophication, and watercress can absorb nitrogen, phosphorus, potassium in eutrophic water body, thereby the characteristic of purifying water body, for grass carp high yielding culture provides effective development space.Meanwhile, gathered in the crops the watercress being of high nutritive value, when harvesting, part watercress can provide feed for grass carp again.This breeding mode is simple to operate, convenient management, and good in economic efficiency.
