Abstract

The invention relates to a method for cultivating catfish, which is characterized in that the area of intensive high-productivity pond is 1-2 mu, and water depth is 1.2-1.5 meter. The optimal length of fish strain is 6-8 centimeter, and the cultivation fish number is 6000-8000.The daily bait feed amount is 10-15% of the fish weight when temperature is above 30 Deg. C, and when the temperature is lower than 22 Deg. C, the bait amount should be less. The pond should be disinfected with calcium lime or bleaching powder before catfish cultivation, cultures water with manual and livestock manure, and cultivates when there is no medicine and the plankton breeding is high. The bait feed should be carried out at a regular time, with regular amount, at regular position and with regular quality. When there is disease attack, the 1ppm bleaching powder can be sprayed into water for every 10 -15 days, or mixes some antibiotics with bait to prevent bacterial colonitis. For severe rotifer, the 0.7 ppm copper sulfate and ferric persulfate (0.5: 0.2)can be sprayed into water.

Description

A kind of cultural method of gold-wire catfish

Technical field

The present invention relates to a kind of cultural method of gold-wire catfish.

Background technology

Catfish is called beard silver carp, glutinous fish, hito again, the cub fish.The notable feature of this fish is that the whole body does not have squama, the many mucus of body surface, and a flat mouth is wealthy, and last lower jaw has four beards.The best of catfish eats season between midspring and midsummer.Catfish not only contains abundant nutrition as other fishes, and fine and tender taste, delicious strong, thorn less, appetizing, easily digestion, be particularly suitable for old man and children.Protein that catfish contains and fat are more, and weak deficient, malnutritive people is had dietary function preferably.Catfish is the good merchantable brand of lactagogue, and nourishing yin and nourishing blood, bowl spares gas, appetizing, diuretic actions are arranged, and is the essential food of women's dietotherapy in postpartum nourishing.The gold-wire catfish body colour is golden yellow, is a good fish culture kind of beard Nian section.Advantages such as it is good to have meat, and growth is fast, and feeding habits are wide, and adaptability is strong are propagated the economic benefit height artificially.

Summary of the invention

The present invention relates to a kind of cultural method of gold-wire catfish, comprise and select special pond to cultivate the highly dense intensive culture; The fresh food of throwing something and feeding increases animal protein; Strengthen feeding and management, prevent that fish disease from three parts taking place.It is characterized in that: (1) selects special pond to cultivate the highly dense intensive culture.The gold-wire catfish lower oxygen concentration resistance, premunition is strong, to the wide adaptability of environment.General intensive culture high yield fishpond area is a 1-2 mu, depth of water 1.2-1.5 rice.Cutting one another's throats often appears in gold-wire catfish intraspecific competition fierceness, and weak fish eats phenomenon by force.Therefore, pond culture spun gold Nian, the fingerling specification to make every effort to neat generally with the fingerling of putting 6-8 centimetre of specification in a suitable place to breed for well.Every mu is put in a suitable place to breed the amount of educating is the 6000-8000 tail, to keep fingerling survival rate and higher fish crop is preferably arranged.Place with good conditionsi will be taked to catch and be stayed little wheel to catch measure greatly, prevents that big fish swallowing little fish.(2) fresh food of throwing something and feeding increases animal protein.Gold-wire catfish is an ominivore-fish, the small fish that mainly ingests in natural waters, shrimp and aquatic insect, zoobenthos and corrupt livestock and poultry corpse.Propagate the extensive stock bait of to ingest under the condition artificially.Plant bait such as various soya-bean cake, flour, bran etc.But preferably use feed of animal origin such as fishes and shrimps, muckworm, spiral shell freshwater mussel, slaughter house offcuts, pluck etc.The fresh food of throwing something and feeding increases animal protein, is the important assurance of gold-wire catfish stable high yield.When lacking animal bait, available fish meal or feed of animal origin are smashed to pieces and are stirred mashedly, are blended in soya-bean cake, throw something and feed in the sugared bran feed, and temperature is more than 30 ℃ the time, every day feeding volume by the 10%-15% of fish body weight, when temperature drops to below 22 ℃, gradually reduce daily ration, feeding quantity.(3) strengthen feeding and management, prevent that fish disease from taking place.Before the gold-wire catfish kind is gone into the pond, use the sterilization of cleaning up the pond of quicklime or bleaching powder, the animal manure training water quality of choosing then treats that the property of medicine disappears, and puts fingerling again when hydroplankton breeds the peak.To adhere to during feeding and management that " regularly, location, decide matter, quantitative " throw something and feed.Take place season in fish disease, will be with the bleaching powder of the 1ppm full pool spilling head of sizing mixing every 10-15 days.Or in bait, admix antibiotic medicines such as terramycin, can prevent and treat bacterial enteritis disease effectively.To endangering serious trichodinasis, but the water-soluble full pool spilling head of the copper sulphate of chilodoniasis 0.7ppm and ferrous sulfate (0.5: 0.2).Adhere to medication prevention, can control the generation of fish disease and popular effectively.

Specific implementation method

1. select special pond to cultivate the highly dense intensive culture.The gold-wire catfish lower oxygen concentration resistance, premunition is strong, to the wide adaptability of environment.General intensive culture high yield fishpond area is a 1-2 mu, depth of water 1.2-1.5 rice.Cutting one another's throats often appears in gold-wire catfish intraspecific competition fierceness, and weak fish eats phenomenon by force.Therefore, pond culture spun gold Nian, the fingerling specification to make every effort to neat generally with the fingerling of putting 6-8 centimetre of specification in a suitable place to breed for well.Every mu is put in a suitable place to breed the amount of educating is the 6000-8000 tail, to keep fingerling survival rate and higher fish crop is preferably arranged.Place with good conditionsi will be taked to catch and be stayed little wheel to catch measure greatly, prevents that big fish swallowing little fish.

2. the fresh food of throwing something and feeding increases animal protein.Gold-wire catfish is an ominivore-fish, the small fish that mainly ingests in natural waters, shrimp and aquatic insect, zoobenthos and corrupt livestock and poultry corpse.Propagate the extensive stock bait of to ingest under the condition artificially.Plant bait such as various soya-bean cake, flour, bran etc.But preferably use feed of animal origin such as fishes and shrimps, muckworm, spiral shell freshwater mussel, slaughter house offcuts, pluck etc.The fresh food of throwing something and feeding increases animal protein, is the important assurance of gold-wire catfish stable high yield.When lacking animal bait, available fish meal or feed of animal origin are smashed to pieces and are stirred mashedly, are blended in soya-bean cake, throw something and feed in the sugared bran feed, and temperature is more than 30 ℃ the time, every day feeding volume by the 10%-15% of fish body weight, when temperature drops to below 22 ℃, gradually reduce daily ration, feeding quantity.

3. reinforcement feeding and management prevents that fish disease from taking place.Before the gold-wire catfish kind is gone into the pond, use the sterilization of cleaning up the pond of quicklime or bleaching powder, the animal manure training water quality of choosing then treats that the property of medicine disappears, and puts fingerling again when hydroplankton breeds the peak.To adhere to during feeding and management that " regularly, location, decide matter, quantitative " throw something and feed.Take place season in fish disease, will be with the bleaching powder of the 1ppm full pool spilling head of sizing mixing every 10-15 days.Or in bait, admix antibiotic medicines such as terramycin, can prevent and treat bacterial enteritis disease effectively.To endangering serious trichodinasis, but the water-soluble full pool spilling head of the copper sulphate of chilodoniasis 0.7ppm and ferrous sulfate (0.5: 0.2).Adhere to medication prevention, can control the generation of fish disease and popular effectively.
