Abstract
A method for taming and breeding burbot fry by using artificial mixed feed belongs to the field of artificial fish breeding. According to the invention, from view point of culture pond design, water quality regulation and control, released density, taming way, feeding way and daily management, the problem that burbot fry can not intake artificial mixed feed completely in the field can be solved successfully, and 300 burbot fry can be bred successfully.
Description
Technical field
The invention belongs to cultured fishes field.
Background technology
Lawver (Lota lota Linnaeus) has another name called mountain catfish, bosom, mountain, mountain cod, belongs to Gadiformes (Gadiformes), cod suborder (Ga-doidae), gadidae (Gadidae), lawver belongs to (Lata), is fresh water kind unique in gadid.Be distributed in the partial rivers in the European the Caspian Sea to the north of north latitude 40 degree, the river course of Black Sea, bay and North America more, be only distributed in Heillongjiang River system, Song Hua River, the Wusuli River, the Yalu River and Eerqisihe River, Xinjiang in China.Lawver belongs to the typical cold aqueous end and dwells, with carnivorous be main fish.In May, 2012, this kind was introduced in Beijing first, at fishing ground flowing water cultures such as Miyun, Huairou, Tongzhou, carried out artifical compound feed domestication of throwing something and feeding in breeding process.Domestication lawver is the technical barrier of this area.
Summary of the invention
Its concrete cultural technique step is as follows:
1), culturing pool design: culturing pool material is cement pit or glass jar, is provided with upper and lower water, can ensure that water circulation is unimpeded.According to the life habit of lawver fish, things concealed is set in the middle of pond.
2), regulating and controlling water quality: before breeding water enters pond, enter sedimentation basin aeration, keep dissolved oxygen amount at more than 6mg/l; Utilize underground water or air-conditioning etc., regulation and control lawver fish culture water temperature is at 10-20 DEG C.
3), cultivation density: in flowing water culture pond, be 3-8cm, cultivation density 600-1000 tail/m when lawver fry body is long
2; When lawver fry body length is 8-15cm, cultivation density 400-600 tail/m
2; When lawver fry body length is 15-20cm, cultivation density 200-400 tail/m
2; When lawver fry body length is 20cm, cultivation density 100-200 tail/m
2.
4), fry domestication: the long 3-8cm of fry body part by weight of throwing something and feeding is that the flesh of fish of 1:1 and artifical compound feed are tamed; Fry is that the flesh of fish of 3:7 and artifical compound feed are tamed at 8-12cm part by weight of throwing something and feeding; Fry all uses artifical compound feed to feed at 12-20cm.
5), in good time adjustment day bait rate and day bait throwing in number of times: when lawver fry is 3-8cm, fish of throwing something and feeding is rotten is mixed into mass, every day 7-8 time with feed; When lawver fry is that 8-12cm throws something and feeds artifical compound feed, every day 6-8 time; When lawver fry is 12-20cm, artifical compound feed of throwing something and feeding, every day 4-6 time.
According to lawver fry growth situation, within every 8-10 days, carry out the adjustment of day feeding rate with the 12-6% of fry body weight.
6), daily management: every day will measure water temperature, dissolved oxygen, gets rid of remaining feed chip and ight soil, pulls dead fish out, keeps water quality limpid.
7), feed formula: artifical compound feed formulation weight ratio: adopt with dregs of beans 27%, fish meal 43%, corn flour 5%, dry ferment 5%, wheat flour 15%, additive 5%.
Successful incubation of the present invention has gone out lawver one seed in age 3000 tail.
Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is described in further detail.
1), culturing pool design: culturing pool material is cement pit or glass jar (diameter 1.5 meters, high 0.8 meter), is provided with upper and lower water, can ensures that water circulation is unimpeded.According to the life habit of lawver fish, things concealed is set in the middle of pond.
2), regulating and controlling water quality: before breeding water enters pond, enter sedimentation basin aeration, keep dissolved oxygen amount at more than 6mg/l; Utilize underground water or air-conditioning etc., regulation and control lawver fish culture water temperature is at 10-20 DEG C.
3), cultivation density: in flowing water culture pond, be 3-8cm, cultivation density 800 tails/m when lawver fry body is long
2; When lawver fry body length is 8-15cm, cultivation density 500 tails/m
2; When lawver fry body length is 15-20cm, cultivation density 300 tails/m
2; When lawver fry body length is more than 20cm, cultivation density 150 tails/m
2.
4), fry domestication: the long 3-8cm of fry body part by weight of throwing something and feeding is that the flesh of fish of 1:1 and artifical compound feed are tamed; Fry is that the flesh of fish of 3:7 and artifical compound feed are tamed at 8-12cm part by weight of throwing something and feeding; Fry all uses artifical compound feed to feed at 12-20cm.
5), in good time adjustment day bait rate and day bait throwing in number of times: when lawver fry is 3-8cm, every day 8 times; When lawver fry is 8-12cm, every day 6-8 time; When lawver fry is 12-20cm, every day 4-6 time.
According to lawver fry growth situation, every adjustment carrying out day feeding rate for 10 days with the 12-6% of fry body weight.
6), daily management: every day will measure water temperature, dissolved oxygen, gets rid of remaining feed chip and ight soil, pulls dead fish out, keeps water quality limpid.
7), feed formula: artifical compound feed formulation weight ratio: adopt with dregs of beans 27%, fish meal 43%, corn flour 5%, dry ferment 5%, wheat flour 15%, cold water fish forage additive 5%.As long as but protein content is greater than 40% can satisfy condition.
The flesh of fish adopts silver carp or carp or wild fishes fish rotten.Additive adopts the sturgeon feed additive of friendship Heng Xin animal Science and Technology Ltd., because sturgeon is also cold water fish, so be suitable for.But be not limited to this additive, the feed addictive of general cold water fish is all applicable.
Domestication adopts the mode gradually reducing animal feed, through domestication in 3 months, replaces animal bait to cultivate lawver fry completely with Articial bait making.
Above-mentioned example of making is usual embodiment of the present invention, and the simple change done in the claims in the present invention or modification, all should belong to covering scope of the present invention.
