Embodiment 1

[0020] The net cage cultivation technology of S. geschneri is carried out in five steps. Firstly, (1) select 5 grams of S. geschia artificially propagated fry or natural fry, put the fry into 3% salt water for disinfection for 5 minutes; then carry out (2) Put the sterilized gerberian perch fish fry into the net cage at a density of 5 grams, 200 to 300 fish per square meter, and at the same time, put the carabinian carp, crucian carp, and Lasse's carp in the cage. species, the size of which cannot be larger than that of Channa germanii fry, and the density is 5 fish per square meter. Choose the size of the cage from 1 to 5 square meters; then proceed to (3) 2 days after the fry are put into the box, start to feed the artificial feed for domestication, domesticate 4 times a day, and after a week, observe whether there are any snakeheads floating up to snatch food (4) After the fish fry float up and snatch food, the bait is changed to twice a day, once in the morning and once in...

Embodiment 2

[0023] Carry out embodiment 1 repeatedly by the same step as described, difference is in the net cage cultivation technology of G. geschneri genus: step (1) selects 8 grams of gerstii s. Go into 4% saline disinfection for 5 minutes; Step (2) is that 100 tails / square meter are put in the net cage with the sterilized Snakehead fries in step (2), and the net cage specification selects 3 square meters by stocking density; Step (3) fry 3 days after entering the box, start to feed artificial feed for domestication, domesticate 4 times a day, and after a week, observe whether there are any fry of G. perch larvae floating up to grab food; step (5) the size of the favorite fish should not be larger than G. perch Channa fry, and the density is 8 fish / square meter.

Embodiment 3

[0025] Carry out embodiment 1 repeatedly by the same steps as described, difference is in the net cage culture technology of Ge's perch channa: step (1) selects 10 grams of 10 grams of chrysalis artificially propagated fry or natural fry, fry is put into 5% salt water disinfection for 5 minutes; step (2) putting the sterilized C. gerbai fish fry into the net cage according to the stocking density of 100 / square meter, and the net cage specification is 5 square meters; step (3) fry into the box After 3 days, start to feed artificial feed for domestication, domesticate 4 times a day, and after a week, observe whether there are any fish fry of Channa germanii floating up to snatch food; step (5) the size of the favorite fish should not be larger than that of Channa gerii fry, and the density is 10 fish / square meter.

Abstract

The invention discloses a Perccottus glenii cage culture technique and management method, and relates to the field of aquaculture. Perccottus glenii is carnivorous fishes and is fed on live baits and mainly fed on larvae of chironomidae, fishes and fish roes in natural world, cannibalization is serious, and when the fish stomachs are dissected, small congeneric fishes often can be found in food. According to the culture technique, expanded feed is put by adopting a cage stocking technique according to the life habits of the Perccottus glenii, feed intake of Perccottus glenii fries is promoted by stocking some fishes liking eating, and the fry growing speed is increased.

Description

technical field [0001] The invention relates to the field of factory farming, and more specifically, the invention relates to a culture technique and a management method of a net-cage of Channa gerii. Background technique [0002] Due to its tender meat, few thorns, delicious taste, rich nutrition and high edible value, it has become more and more popular among consumers in recent years. It has become a special dish in major hotels and restaurants in the north and even the whole country. The prospects are very bright. But in recent years, with the development of economy, the increasing seriousness of industrial pollution and the overfishing of human beings, Snakena gerii has become endangered in many waters rich in resources before. The current market supply of Channa germanii basically comes from natural waters, and the strong market demand has further deteriorated the resource situation. Contents of the invention [0003] The problem to be solved by the present inventi...
