Abstract
The invention discloses a full artificial ecological simulation breeding technology of burbot, comprising the following steps: (1) designing a culture pond with unimpeded water circulation; (2) processing culture water to be fresh and clean; (3) adjusting and maintaining water temperature within the range of 10-20 DEG C; (4) reforming culture environment, arranging a place for the burbot to perch in dark place; (5) timely adjusting the stocking density of the burbot according to body length of the burbot; and (6) feeding live fish bait according to 10% of the weight of burbot or artificial bait according to 1-3% of the weight of the burbot. The burbot cultured by using the culture technology of the invention grows fast, and has strong vigor, vigorous ingestion, less disease and higher survival rate.
Description
Technical field
The present invention relates to a kind of lawver total man worker ecological simulation cultural technique.
Background technology
Lawver is the unique fresh water kind of rockling, also is the rockling that contains cod-liver oil in the freshwater fish in unique liver, is the peculiar fish of China, the liver delicious flavour, and its nutrition and economic worth are all very high, and it originates in basin, Xinjiang of China Eerqisihe River.In recent years because taking place frequently of overfishing and natural calamity makes that these species are endangered.Province such as Guangdong, Heilungkiang once had and carried out the lawver breed on a small quantity, cultured successful report but have.
Summary of the invention
The purpose of this invention is to provide a kind of lawver total man worker ecological simulation cultural technique that the lawver growth is fast, energetic, ingest vigorous, that disease is few, survival rate is higher that makes.
Particularly, method of the present invention may further comprise the steps:
(1) cultures the pond design
Culture the pond for guaranteeing the unimpeded cement pit of water circulation;
(2) water treatment
Before breeding water is gone into the pond,, impurity in the water is fully precipitated and harmful substance is decomposed earlier through the abundant aeration of sedimentation basin, deposition, if water quality still muddiness also need husky filter make water quality limpid, annual flowing water is cultured;
(3) water temperature is regulated
Extract the water layer and the adjusting of different depth through Various Seasonal and go into means adjusting lawver culturing pool temperature such as pond current, it is maintained in 10 ~ 20 ℃ of scopes;
(4) breeding environment transformation
Build several sunshades with masonry and asbestos shingle at the bottom of culturing the pond, a few enrockment heads of underneath, and the lighttight extra heavy pipe of some heavy property of placement supplies lawver lucifuge on daytime to perch at the bottom of the pond;
(5) regulate cultivation density
According to the cultivation density of the long timely adjustment lawver of lawver body, lawver body relation long and cultivation density is as shown in the table:
According to the cultivation density of the long timely adjustment lawver of lawver body, lawver body relation long and cultivation density is following:
When lawver body length was 5 ~ 10 cm, cultivation density was 200 ~ 300 tails/m
2
When lawver body length was 10 ~ 20 cm, cultivation density was 100 ~ 150 tails/m
2
When lawver body length was 20 ~ 30 cm, cultivation density was 80 ~ 100 tails/m
2
When lawver body length was 30 ~ 40 cm, cultivation density was 1 ~ 20 tail/m
2
(6) bait feeding
Bait during the adult fish culture comprises the wild fishes of the carp, crucian carp, silver carp, flathead and some fishing in reservoir that are fit to bore; Live fish is thrown something and fed; Each feeding volume for culture that lawver weighs sb. 10 ~ 15%; In culturing the pond forage fiss amount be less than culture the lawver body weight 3% the time replenish the live fish of throwing something and feeding, the situation of ingesting of observing fish night every day is in time regulated the bait that feeding volume and change are fit to bore.
Lawver is can the ingest freezing flesh of fish or artitificial food after domestication, throws something and feeds twice every day, and at dusk once, feeding volume is for culturing 2 ~ 3% of lawver body weight, and midnight, once feeding volume was for culturing 1 ~ 2% of lawver body weight; Observe the situation of ingesting of fish night every day, in time regulate the bait that feeding volume and change are fit to bore.
The beneficial effect that the present invention obtains is: when adopting lawver total man worker ecological simulation cultural technique of the present invention to carry out the lawver breed, the lawver growth is fast, and energetic, it is vigorous to ingest, and disease is few, and survival rate is higher.Introduce lawver newly hatched larvae 1,000,000 tails from Xinjiang in by the end of February, 2009 at the beginning of 3 months, lawver newly hatched larvae 400,000 tails of artificial incubation amount to 1,400,000 tails, cultivate 3 months to the long 5cm of body, the cultivation of employing total man worker ecological simulation cultural technique.To in June, 2010, obtain 50 ~ 200 g lawvers, 100,000 tails, average survival 7.1% altogether through 12 months cultivations.In early March, 2010 hatches lawver newly hatched larvae 2,400,000 tails, behind the long 5cm of body, adopts total man worker's ecological simulation cultural technique to cultivate, and in September, 2010, obtains juvenile fish 310,000 tails about 10 cm altogether, and average survival reaches 12.9 %.
