First, the cultivation of large-size squid species:
1. Pond conditions:
The ponds cultured with squid require sandy bottom, less silt, an area of ​​2-3 mu, a water depth of 1.5 meters or more, convenient irrigation and drainage, light water quality, no turbidity, no effluent, and a small amount of fish ponds with drowning plants. The new pool should be determined according to the soil quality. Acid pools and ponds with turbid water are not suitable for rearing catfish.
2. Pond preparation and feed fish breeding:
(1) On April 5th, use quicklime to clean the ponds, and pile grass fertilizers around the corners of the pond around April 10 (if the bottom of the pond is not over-fertilized), add 0.8-1.Om of fresh water to cultivate water quality. To cultivate natural feed for feed fish.
(2) Feed fish is generally carp seedlings. Around April 15th, fish nests (floats) attached to the eggs of salmon are hatched in ponds. The density of fry is generally controlled at about 500,000 per mu. The eggs can be released in 2-3 batches, one batch a day, such as 1-3-5. This can give consideration to the malnutrition of the seedlings that have different specifications.
(3) Control the feed fish's specifications by controlling feed intake. General stocking specifications of about 2 cm of salmon fry, feed fish specifications can be controlled at about 1.2 cm.
3. Carp stocking and breeding:
(1) The day before the eel fry release, add water 10 centimeters (for example, water quality can be changed to 1/3).
(2) The stocking density of carp fry is 4000 fish/mu.
(3) Check the density of the feed fish in the pool and promptly supplement the feed fish.
(4) Pay attention to changes in water quality and weather conditions.
(5) Disease prevention and control:
It is mainly ciliates, such as oblique beetles and trichoderma, which have a low incidence of ringworms. See methods for prevention and control of adult fish culture.
Second, carp adult fish breeding:
1. Fish pond conditions:
The ponds for squid adult fish farming require sandy bottom, less silt (about 15cm), area of ​​3-8 acres, water depth of more than 1.5 meters, convenient drainage and irrigation, good water quality, no sewage flow, and a small amount of fish ponds with drowning plants . Around the pool, we must also dig a shallow ditch with a depth of 30-40 cm for the fishing of carp.
2. Pond preparation and feed fish breeding:
(1) Use limed clear pond for disinfection 10-12 days before bait fish stocking.
(2) Natural bait cultivation: In the 7 days before the stocking of feed fry (carp, silver carp, squid, etc.), add water to 60 cm, and apply about 150 kg of fertiliser per acre of water (but not apply fertilizer at the bottom of the pond). Develop zooplankton such as rotifers and Cladocera.
(3) Breeding of feed fish:
1 Feed Fish Variety and Stocking Density: Feed fish is generally white sea bass, squid, squid, etc., and the amount of mu fish is about 300,000.
2 The day before the feed fry was released, add 10 cm of fresh water to make the water fresh and rich in natural food. After the fry is released, it is not necessary to feed it immediately, but it is necessary to observe the fry's density, constitution, growth rate, and the number of red worms in the water every day until the number of red worms is reduced. When the fry are foraging around the pond, they immediately use the thick slurry to “spout the beachâ€. , and several times a day to check the situation of each feeding point, eat in the early feed to add Tim, in the later control feed fish specifications to be controlled. General stocked 8-10cm carp species, feed fish specifications should be controlled at about 3-4cm.
3 Feeding fish can also put some old loach when it is cultivated. The small loach produced can be used as a high-quality feed for trout.
4 The proportion of cod farming area and feed pond area is generally 1:3--4.
3. Catfish species stocking:
(1) Before stocking puffer fish, drain half of the pool water and then fill it with fresh water to make the pool water slightly lean. Later, the water depth is gradually added to more than 1.5 meters.
(2) Stocking Density: About 800 Acres are placed.
4. Feeding management:
(1) feed feeding:
1 feed fish can choose carp, carp, carp, grass carp and so on.
2 feeding technology:
a. Feeding supplemental feed fish on a regular basis (1 to 3 days).
b. Judging the amount of feed fish in the pond:
When there is enough feed fish in the pond, the carp catches the bait fish at the bottom of the water, so the surface of the pond is only small and small. When listening, the sound of water produced by fish catching feed fish is small, and the time interval is large. If there is a shortage of feed fish in the pool, the carp feeds the feed fish to the water layer, so the water spray is large, the sound emitted is frequent, and the sound is loud. If you see a group of squid hunting for fish at the edge of the pool, then the pool calls: The feed fish has basically finished eating.
c. Palatability of feed fish:
The size of the palatability feed fish is generally about 1/3 of the length of the carp, and if the feed fish has a non-uniform size, the fish feed must be sieved to remove the large-size feed fish.
(3) Water Quality Management:
1 The quality of ponds and ponds must be kept at a standard of “fat, live, and cool†throughout the year, and the transparency of the pool water should be maintained at about 3 gel meters. Always add new water, especially in the high-temperature period from June to September, add water every five to seven days, each time adding 15-20cm of water. If you use drugs more than once, you need to change the water to prevent phytotoxicity.
2 If the weather is abnormal, add water immediately and keep the water level of the fish pond relatively stable. This provides good environmental conditions for the growth of carp. If the water is turbid, use 1 kg of alum per acre or quicklime 5 - 7.5 kg of water to splash water at Quanchipu.
3 Install an aerator to prevent the catfish from lacking oxygen and float the head. Normally, the oxygen is turned on at noon in sunny or less cloudy weather. If the weather is hot, it is switched on from midnight to early morning.
4 prepare some hydrogen peroxide (more than 30% content) or aeration spirit, can be used for rescue when the squid floating head. Hydrogen peroxide Usage: Use 250 ml of hydrogen peroxide per acre, add 500 ml of water, and add 2% of ferrous sulfate 3-5 ml. Oxygen use see instructions.
5. Fish disease control:
(1) Ciliate disease: mainly parasitized on the body surface, fins and ankles of salmon, and parasites are mainly trichomonads and slug. The disease spread rapidly. When the number of parasites is small, it has little effect on the fish's activity. When there is a large number of parasites, the fish will not eat. The gray-white spots on the fish body are visible to the naked eye and the swimming loses its balance and then dies.
Control methods: Early aldehyde 20ppm watered Quanchiposa. The effect of copper sulfate on the oblique worms is not ideal and has a certain effect on worms. The fish killer in Shanghai has a significant curative effect on the oblique tubeworm.
(2) Anchor head lice disease: The part of the fish body that is drilled by the head of an iron annelid. The surrounding tissues are often inflammatory and reddened, followed by tissue necrosis.
Control methods:
1Each acre per meter water depth uses “strongly exterminator†(Beijing Xinyang) or “enemy fish†(Shanxi Fish and shrimp Group) full of water in the whole pool (the carp is sensitive to trichlorfon and controls fish disease The crystal trichlorfon is disabled.
2 The baits of fish on the bait were parasitized with anchor heads. They were bathed with 20ppm potassium permanganate solution for 15 minutes and then fed.
(3) Fish larvae: The body of the fish is attached to the worm-like worm body, and the squid's food intake is reduced. The body is wasted and growth stops.
Control methods: with the anchor head.
(4) Cylindrotheca sinensis: The parasitoid is parasitized in the stern of the fish, the body of the diseased fish is thin, and the body color is dark. It occurs in both summer flowering and adult fish stages, and the mortality rate is high.
Control methods: Use “Worm-killing King†produced in Wuxi or “Fish-Like Comet II†produced in Beijing. See instructions for use.
(5) Bacterial gills: 0.27 kilograms of "strong chlorine" per acre per meter of water depth, or evenly splashed with 0.33 kg of water. At the same time take medicine baits 7-10 days.
(6) Hemorrhagic disease: In the adult fish breeding stage, pathogens are often carried by feed fish. After the feed fish suffering from bacterial diseases are eaten by carp, symptoms such as surface inflammation, liver and kidney carriers, and ascites often appear. treatment method:
1 Use "strong chlorine" 0.4ppm (or use "floating powder essence", dibromohydantoin, bromochloroheine, etc.) to sprinkling the whole pool of water, repeating at intervals of one day. Such as long-term use of drugs without changing the pool, you must first change the water and then medication to prevent phytotoxicity.
2 For squid special "Zhuoxin", feed 12.5 kilograms per bag. The bait production method is as follows:
a. Use wheat flour 50%, vegetable cake 50%, mix well;
b. Method of bait preparation: Weigh a certain amount of water according to 65% of the feed amount, and then add the medicine according to the amount of feed. After the medicine is dissolved into a medicine, mix it into the human feed, place it by hand or step with the foot, and put it in one hour. The feed fish fed to the trout pond are eaten (generally, they are required to feed around 4 pm, because the trout feeds in the evening with the most fierce predation, and the feed fish swallows the bait and is just swallowed by the trout).
c. Bait feeding days depends on the condition of the carp, usually 5-10 days.
d. Precautions: Disinfection with sterile drugs after changing water. At the same time, the bait fish should be put before feeding the bait, and the bait should be fed at about 6% of the bait fish weight.
