Abstract
A fresh water crab culturing method belongs to the field of animal culture and especially relates to a crab culturing method. A fresh water crab culturing method with fast crab growing speed and high crab quality is provided. The technical scheme of the fresh water crab culturing method is that a pond is chosen; the pond is pumped and cleaned from November to December each year; after exposure to the sun, 120 kg quicklime is spread on each mu for disinfection; oxygenation pipes are paved on the bottom of the pond; the oxygenation pipes are connected with an oxygenation machine; photosynthetic bacteria is placed in water in the pond; water plants are planted in the pond; a pottery jar is placed in the pond; juvenile crabs are put into the pond in early March; during crab culture, baits are placed once in the morning and evening each day; bait weight weighs 4% to 5% of crab weights; and when the crabs weigh 100 to 150g, the crabs can be caught and sold on the market.
Description
Technical field
the invention belongs to animal-breeding field, especially relate to the cultural method of a kind of crab.
Background technology
crab, also known as river crab, is fresh water crustacean, grows up in fresh water, crab delicious, nutritious.In current aquatic products, crab is one of the wellst sold and in short supply aquatic products, and sales volume is large, and market is more stable.
at present, the production of crab still can not meet the demand in market, although there are a lot of provinces and cities in the whole nation in development crab cultivation project now, the technology propagating crab artificially is also rear a lot of not enough, and people are to the experience of artificial crab farming also imperfection.Cause the specification of crab less, generally at 50 ~ 100g, do not meet the needs of consumer.
Summary of the invention
the present invention is exactly for the problems referred to above, provides a kind of crab fast growth and the cultural method of the high a kind of fresh water crab of crab quality.
to achieve these goals, the present invention adopts following technical scheme.
a cultural method for fresh water crab, comprises the following steps.
(1) pond is selected; Select the good free of contamination waters of water quality, place fence, build up pond.
(2) do pool desilting in annual 11 ~ December, the mud staying 13 ~ 15cm dark is advisable, after being exposed to the sun, with the thorough disinfection of 120Kg/ mu quicklime.
(3) plastic greenhouse is set above pond.
(4) in pond, small fish is cultivated.
(5) lay oxygen increasing tube in pond bottom, oxygen increasing tube is connected with aerator, is filled oxygen in pond by aerator.
(6) in pond water, photosynthetic bacteria is thrown in; Noxious material in water is absorbed by photosynthetic bacteria.
(7) in pond, duckweed, water peanut and Azolla imbricata is planted.
(8) every square metre of placement 2 crocks in pond.
(9) throw in juvenile crab during the beginning of March, in launch process, water temperature is advisable at 10 ~ 12 DEG C.
(10) cultivate in crab process, every day is each input bait sooner or later, and each injected volume is 4% ~ 5% of crab body weight.
(11) listing can be fished for when crab grows to 100 ~ 150g.
further, before input juvenile crab, in pond, a collection of water earthworm is thrown in; Water earthworm not only can be used for crab to eat, and also can purify water.
further, the depth of water in pond remains on 0.9 ~ 1.2m.
beneficial effect of the present invention: the present invention is arranged by the pond environment of science and bait is thrown in, and make the survival rate of crab high, growth rate is fast.Different times throws in different bait, not only meets the growth needs of crab, and can promote the delicious degree of crab meat.
Embodiment
the cultural method of crab, comprises the following steps.
(1) pond is selected; Select the good free of contamination waters of water quality, place fence, build up pond.
(2) do pool desilting in annual 11 ~ December, the mud staying 13 ~ 15cm dark is advisable, after being exposed to the sun, with the thorough disinfection of 120Kg/ mu quicklime.
(3) plastic greenhouse is set above pond.
(4) in pond, small fish is cultivated.
(5) lay oxygen increasing tube in pond bottom, oxygen increasing tube is connected with aerator, is filled oxygen in pond by aerator.
(6) in pond water, photosynthetic bacteria is thrown in; Noxious material in water is absorbed by photosynthetic bacteria.
(7) in pond, duckweed, water peanut and Azolla imbricata is planted.
(8) every square metre of placement 2 crocks in pond.
(9) throw in juvenile crab during the beginning of March, in launch process, water temperature is advisable at 10 ~ 12 DEG C.
(10) cultivate in crab process, every day is each input bait sooner or later, and each injected volume is 4% ~ 5% of crab body weight.
(11) listing can be fished for when crab grows to 100 ~ 150g.
further, before input juvenile crab, throw in a collection of water earthworm in pond, water earthworm not only can be used for crab to eat, and also can purify water.
further, the depth of water in pond remains on 0.9 ~ 1.2m.
introduce feeding process of the present invention below.
first, pond is selected; Select the good free of contamination waters of water quality, place fence, build up pond; Do pool desilting in annual 11 ~ December, the mud staying 13 ~ 15cm dark is advisable, after being exposed to the sun, with the thorough disinfection of 120Kg/ mu quicklime; Above pond, plastic greenhouse is set; Small fish is cultivated in pond; Lay oxygen increasing tube in pond bottom, oxygen increasing tube is connected with aerator, is filled oxygen in pond by aerator; Photosynthetic bacteria is thrown in pond water; Noxious material in water is absorbed by photosynthetic bacteria; Duckweed, water peanut and Azolla imbricata is planted in pond; 2 crocks are placed for every square metre in pond; Throw in juvenile crab during the beginning of March, in launch process, water temperature is advisable at 10 ~ 12 DEG C; In cultivation crab process, every day is each input bait sooner or later, and each injected volume is 4% ~ 5% of crab body weight; Listing can be fished for when crab grows to 100 ~ 150g.
