Abstract
The invention discloses a crisped grass carp fast culturing method comprising the steps such as pond cleaning and disinfection, water storing and net building, fry placing, feeding and stocking, disease control, and the like. In the water storing and net building step, the water depth in a fish pond is controlled to be 7-9m; and two layers of net cages are built at a depth of 5-7m. In the fry placing step, a fry placement amount is 2-4 fries/m<3>. In the feeding and stocking step, a feed is composed of broad bean, sudangrass, ryegrass, rice sprout and rape seed dreg; and the feed is used for feeding three times a day, wherein feeding is carried out on time respectively in the early morning, at noon, and at dusk. According to the invention, net cage culturing is adopted, such that fish body energy consumption can be reduced, fish body growth can be accelerated, and culturing time can be greatly reduced. Also, broad bean is adopted as the main raw material of the culturing feed, and sudangrass, ryegrass, rice sprout and rape seed dreg are used as auxiliary materials, such that culturing cost can be reduced. With the method, crisped grass carp crisping time is shortened to 60-80 days.
Description
Technical field
The invention belongs to cultural technique field, be specifically related to a kind of method for quickly breeding of grisped grass carp.
Technical background
Grass carp belongs to one of four large Chinese carps, is the main cultured fishes of China, its fast growth, and output is high, but muscle is more loose, needs just not fall apart under curing condition, have impact on mouthfeel and price.By feeding broad bean, namely brittle cultivation can make its meat of grass carp become fragile, and the successful grass carp of brittle cultivation claims grisped grass carp or brittle grass carp.
Solid, the soft cunning of grisped grass carp meat, salubrious, crisp mouth, delicious flavour.Research shows, the fat of grisped grass carp and the content of Fresh ear field are apparently higher than grass carp, and also higher than some other fish, therefore, grisped grass carp taste is better, and mouthfeel is unique, because deeply liking by consumer.Grisped grass carp is excellent cultivation object, but the feed of raising grisped grass carp is mainly based on broad bean, and do not add other any feeds, cost is higher, and brittle culturing time is longer.
Summary of the invention
For the problems referred to above, the object of the present invention is to provide a kind of method for quickly breeding of grisped grass carp.
Technical solution of the present invention is as follows.
A method for quickly breeding for grisped grass carp, comprises sterilization of cleaning up the pond, net is taken in retaining, throws in the steps such as fry, feeding are put in a suitable place to breed, disease control; Wherein, it is 7-9 rice that the depth of water controlling fishpond is taken in net in described retaining, builds two-layer net cage at depth of water 5-7 rice; The injected volume throwing in fry in fry is 2-4 bar/cubic meter; The feed that use put in a suitable place to breed by feeding is made up of broad bean, Sudan grass, perennial ryegrass, rice sprout, cake-shaped rape seed dregs, and adopts the mode of three times of throwing something and feeding every day, namely respectively at early morning, noon, to feed intake nursing at dusk on time.
The specification of described input fry is 0.5-5 jin/bar.
Described early morning, noon, the at dusk ratio of charged material weight are 2: 0.5-1: 1-2.
In described feed, the weight proportion of broad bean, Sudan grass, perennial ryegrass, rice sprout, cake-shaped rape seed dregs is: broad bean 80 parts, Sudan grass 10-20 part, perennial ryegrass 5-10 part, rice sprout 1-5 part, cake-shaped rape seed dregs 1-5.
Beneficial effect of the present invention:
(1) the present invention adopts cage culture, utilizes the travelling of fish in current, stormy waves and case that water body inside and outside case is constantly exchanged, takes away old water in case, and swap-in height holds the new water of oxygen and the natural bait brought in the large water surface; The activity of the fish of net cage restriction simultaneously body, reduce the energy ezpenditure of fish body, the growth of accelerating fish body, significantly reduces culturing time;
(2) breeding feed raw material of the present invention is based on broad bean, is equipped with Sudan grass, perennial ryegrass, rice sprout, cake-shaped rape seed dregs etc. and cultivates, can reduce aquaculture cost, make foreshorten to 60-80 days the brittle time of grisped grass carp.
