Abstract
The invention discloses a kind of cultural methods of cray, comprising the following steps: (1) selection of land builds pond；(2) disinfection kind grass；(3) shrimp seedling is launched；(4) it raises.Cultural method provided by the present invention is reasonable, and aquaculture cost is low, and listing rate is high, substantially increases the economic benefit of cray cultivation.
Description
Technical field
The present invention relates to technical field of aquaculture, in particular to a kind of cultural method of cray.
Background technique
Freshwater lobster is commonly called as cray, belongs to Arthropoda Crustacea Decapoda Palinuridae, and head and chest are thicker
Greatly, shell is hard, delicious meat, is a kind of nutrient tonification food of low fat low cholesterol high protein.Freshwater lobster, which removes, to be had
Figure is larger, and meat is fertile outer, and it is short that there are also growth cycles, and yield is high, eats miscellaneous adaptable feature, is particularly suitable for artificial commodity
Property cultivation.But since cultural technique is unreasonable, cause cray aquaculture cost high, listing rate is low, or even cultivation failure.
Summary of the invention
The purpose of the present invention is making improvement and innovation for shortcoming and defect present in background technique, provide a kind of small
The cultural method of lobster, the cultural method cultural method is reasonable, and aquaculture cost is low, and listing rate is high, substantially increases cray and supports
The economic benefit grown.
To achieve the above object, the technical solution adopted by the present invention is that: a kind of cultural method of cray, including following step
It is rapid:
(1) selection of land builds pond: selecting to have abundant water resources, ground is broad, loam soil is as aquaculture pond, aquaculture pond scrapes out rectangle, repairs
Chi Geng is built, and is provided with anti-escape network on Chi Geng and into discharge outlet；There is cross zanjon along center line digging in aquaculture pond, fills water
1.5 ~ 2m of Shi Shuishen；Zanjon to the ground levelling between the ridge of pond as cultivation platform, fill cultivate after water the depth of water of platform be 1 ~
1.5m；
(2) disinfection kind grass: pond is shone before aquaculture pond water filling and is poured water into pond after 2 ~ 3 days to cultivation 10 ~ 15cm of the platform depth of water, life is applied
Lime disinfection replaces the water in pond, makes the pH value of water between 7 ~ 8 after disinfection, keeping the depth of water of cultivation platform is 1 ~ 1.5m, so
Water plant and planktonic algae plant are planted along Chi Geng afterwards, water plant area is made to account for the 1/3 of aquaculture pond；
(3) launch shrimp seedling: selection healthy growth, limbs are complete, a length of 2 ~ 4cm of body shrimp seedling, impregnate 10 ~ 12 minutes in salt water
After launch in aquaculture pond, cultivation density be 90 ~ 110kg/ mus；
(4) it raises: respectively feeding primary special feed sooner or later 7 ~ October, respectively feed a normal diet sooner or later in remaining month, sooner or later
The ratio between feedstuff feeding amount be 1:4, daily feedstuff feeding amount be cray weight 12 ~ 15%, and meet high temperature, rainy weather or
When water quality is not good enough, daily feedstuff feeding amount is the 8 ~ 10% of cray weight；A water is changed weekly, and each quantity of exchanged water is original water
The 50% of amount；Every 10 ~ 12 days with quick lime regulating water quality pH value, make the pH value of water between 7 ~ 8.Such as the lasting cloudy day, daily
Xiang Chizhong is oxygenated 8 hours.
Preferably, the width of Chi Geng described in step (1) is 3 ~ 3.5m, and the gradient of Chi Geng is 20 ~ 25 °；The zanjon
Width is 1 ~ 2m, and the gradient is 40 ~ 45 °.
Preferably, the dosage of quick lime described in step (2) is 65 ~ 75kg/ mus, and the water plant is hydrilla verticillata, Yi Le
One or more of algae, eel grass, hornwort, Eichhornia crassipes, water peanut, water duckweed, water caltrop, alternanthera philoxeroides；The swim alga
Class plant is one or more of green alga, chlorella, diatom.
Preferably, the concentration of salt water described in step (3) is 2 ~ 3%.
Preferably, special feed described in the step (4) is made of the raw material of following parts by weight: 15 ~ 22 parts of wheat bran, dimension
Raw element C3 ~ 6 part, 5 ~ 7 parts of pectin, 4 ~ 6 parts of dendrobium nobile, 6 ~ 8 parts of calcium powder, 18 ~ 20 parts of rape cake, 20 ~ 22 parts of soya-bean cake, 3 ~ 5 parts of bone meal,
6 ~ 8 parts of silkworm chrysalis, 5 ~ 7 parts of spiral shell meat.
Preferably, normal diet described in the step (4) is made of the raw material of following parts by weight: 10 ~ 12 parts of peanut press pulp,
8 ~ 12 parts of wheat bran, 25 ~ 28 parts of dregs of beans, 6 ~ 9 parts of egg shell, 13 ~ 14 parts of carrot, 4 ~ 7 parts of leaf lettuce, 6 ~ 9 parts of spinach, corn is swollen
Change 11 ~ 14 parts of powder, 10 ~ 12 parts of shrimp shell meal, 0.4 ~ 0 .6 parts of licorice powder.
Advantages of the present invention and the utility model has the advantages that
Cross zanjon is arranged in the present invention in aquaculture pond, can adjust water temperature by zanjon in hot weather, avoid aquaculture pond
Middle water temperature over-high, and be provided with cultivation platform and inhabited for cray.The present invention plants a large amount of water plant and is floated in aquaculture pond
Algae is swum, habitat and a large amount of food is provided for cray, is conducive to the growth of cray.The present invention is in 7 ~ October
Season is listed, the special feed for being mixed with of animal or plant nature feed is fed, meets the growth demand of cray, while also promoting small dragon
Shrimp fast-growth substantially increases yield and listing rate；It month other than 7 ~ October feeds plant feed and greatly reduces
Aquaculture cost.
Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, with reference to embodiments, to the present invention
It is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, it is not used to
Limit the present invention.
Embodiment 1
A kind of cultural method of cray, comprising the following steps:
