罗非鱼属寒带广盐性鱼类,水温在18℃～38℃能成长

The Luo non- fish exists to eat sex widely, bear low oxygen, quick growth, rise disease little, breed a trick strong etc. advantage, the besides easy Huan keeps, market good, today at our country farming contrast universal, is get many fishing agricultures in the place and farming unit increase to accept of main farming species, for is Luo non- fish currently international market up contrast depressed, therefore is intensive to turn a farming make rapid progress.However thick put to turn a farming to also bring some headlines gradually, many farming doors create quantity because of being thoughtful to seek, the net continuously throws in toward farming water body surfeits of animal feed and fertilizer etc., make fluid matter continue to smear, fish existence environment each condition overs bottom, often go into action much quantity dead fish and come across omens like barracks in the market,etc because of the hygiene problem, carry a camp for farming to bring to lose very greatly.At the same time, the Luo non- fish belongs to tropic fish and keep to the farming environment and the Huan whole cure to request that checking against is uncommon, applies for to the fluid matter opposite and higher, so the fluid matter scheme becomes Luo the key of non- fish farming success or failure in the farming.A, grand choice headwatersThe Luo non- fish belongs to Frigid Zone wide salt fish, the water temperature can grow up in 18 ℃ ~38 ℃ , the water temperature of the most suitable growth is 28 ℃ ~32 ℃ , ability low oxygen, at dissolve oxygen is lower than 0.7 milligrams/rise of water body in can still absorb, dissolve in water the oxygen is in 1.6 milligrams/can grow to multiply greatly while rising.Will grow in the thin sea water, growth and stir up, the ability grows in 4.5~10 water bodies in the pH.In the farming, the headwaters is the most basic again most must of aspect, it chooses fluid matter condition and farming success or ually the headwaters condition applies for headwaters motion, ample, pickle 臜 and hygiene, the water temperature is feat, the fluid matter is good, have no decontamination, fit together the country fishery fluid matter standard, at the same time application note, drain convenience, and list note list row.BE noting, the drainage outlet want to set up to block a fish net to have so much, since prevent enemy living creature and wild miscellaneous fish from going into pond, and then can prevent°from escaping fish.The headwaters gets into a farming to want the percolation and the disinfection in the reservoir to put out by killing the cause body in the headwaters and enemy living creature before the pond, similar usually can use 25 grams/sign square rice~30 gram/sign square rice calcium oxide or 1 gram/sign square rice bleach the powder(imply to use a chlorine above 25%) whole pondses sprinkle Sa, can also use 0.5 grams while needing to kill to exterminate insects to harm/sign square the rice is enemy's 100 insect medicine liquid(100 insects of 90% crystal enemies) whole pond Qing box farming, essential water temperature regularly between 18 ℃~38 ℃ , the fluid matter feat fishery is used water dimensions, the headwaters is resolute and have no taint with source, don't seal ice in winter, the surface Tan concusses and takes shelter from the wind setting sun and only shine on ample, the environment is quite, the headwaters ground doesn't become wealth or agriculture infection water current to go into.Two, the strictly pure pond disinfectThe pure pond disinfection can kill to put out water body to the factor of disease and makethe good fluid matter premise acquire a guarantee.Before throwing in seedling to grow, lately old pond all have to pure whole disinfection.Old pond in response to Su in addition to excessive silt, living bottom mire 10 Li rices is then.Put to keep fish 10 days before growing~carry on pure pond disinfection's putting out by killing the cause body and enemy living creature in farming water body with the medicine for 15 days.Generally can adopt to do a pure pond of method or take a pure pond of water two kinds of methods, stem method pure pond, can press each applied calcium oxide 75 kilograms to order about or bleach the powder 4 kgs~5,000 gram;Each one can be controled whole pondses to sprinkle Sa with the calcium oxide 150 kgs while taking a pure pond of water and make possibly pond bottom the mud mix evenly with calcium oxide to completely kill to put out parasite, cause body and wild miscellaneous fish box farming can apply the way that the medicine hangs bag to carry on disinfection, want to be ample to soak, disinfect before water on the new net box.Three, science apply fertilizer to throw baitThe fertilizer, bait anticipates the amount of etc. farming devotion article to influence the growth of the non- fish of Luo, and influence the variety of fluid matter.The Luo non- fish applies for to the fluid matter width of figure not very strict, in the natural water, it is a bottom to stay living creature, water to living insect Zhi and float to visit plant, round insect, organic broken bits and large Zao etc. to mainly absorb object, the plankton in water is probably attracted to it is a food, to the artificial animal feed is also a hobby have been already added.In the farming, it is fatty, make the plankton be placed in good growth status, promote to also probably pass excessively Pei water body of eliminating and melting oxygen and nutrient material, insist good fluid matter, give relief to fish growth.Is many before the fish kind puts to keep, can Shi Zu Ji is fatty, improve the nutrient condition of bottom mire in water body and increase pond nutrient energy, the benefit anticipates at the natural bait of growth.The concrete method is to press each to use familiar the chicken muck is 250 kilograms after Fu~300,000 gram.At farming middle, can also follow Shi Yongs like fluid matter circumstance,etc in water body to make track for fatty, similar usually every 15 day~20 day, is once proper, each time each one can 2 kilograms of nitrogen fertilizer~3 kgs and Lin fatty one kilogram, can also put into in the pond a little amount of green Ping or red Ping, can also act according to a water temperature, fluid matter circumstance is used have no machine fatty or biofertilizer.The Luo non- fish is one of the main objects of the flowing water high definition farming or"the factory turns" farming currently, thick put to turn a farming to need to throw feeding to divide an overall match of animal feed, but feed in the hurl in if don't control science method, not only will Mi fee animal feed, and also be slacken fluid matter, arise various diseases to harm to anticipates by being a bait hurl to feed to want science.The food of Luo non- fish is very wide, under the condition of bottle feeding, or hurl feed various animal feed, if the wheat, corn, and a round flat cake Po...etc. all are its high-quality animal feed.The protein content should is 32%~35% in the later period animal feed and throw the amount of Si as fish body every day total 3%~5% for measuring.When the individual specification is long to go to 200 grams of or so, throw amount of Si adjustable to 2% that the fish body always weighs,and promise that the Si guesses right a protein content in 27%~29%.When its individual attains 300 grams of dominations, the Luo non- fish gets into to grow a quickest period, the day throws amount of Si maintenance's 1%~2% in fish weight, and the Si guesses right a protein content in above 35%.Animal feed can from go together with to assimilate to anticipate, but had better process into grain hurl to feed.Feed in the hurl method up want fashionable"four settle" standard.Every day hurl feed 2 times, the time divides Mei in 8:00 A.M.~at 9:00 and bottom Zhou 3:00~4:00.Each pond still needs to be taken 2~3 baits anticipate Taiwan, for the purpose of fixed-point hurl feedFour, periodically adjust to cure fluid matterThe fluid matter recuperates is feed a conditional root of good fluid matter Di Xi path.Garden pond farming, often replace pond water, maintain refreshing fluid matter, take strict precautions against to float a head and be suffused with pond, dissolving the oxygen should repeatedly maintain in 3 milligrams/rise ually every 15 days domination adds to change new water once and change water each time 10 Li rices~20 Li rices, make pond water level keep about 1.5 meters, low temperature moral integrity can increase to change water number of times appropriately.At farming ages, also need to see the weather, water temperature and fish to absorb a circumstance, suit to open to increase oxygen machine to increase oxygen, change in the weather, the air pressure is low, dissolve oxygen in water is lower than 3 milligrams/rise fish to float a head, enlarge to switch on frequency with switch on time.Reservoir net box farming, often brush a box, wash out a net box filth and adhere to Zao, make water body is weak to float to exchange, also want current to check a box, discover that smashing is solid repair, so as not to run fish or severe fish into the box.Still want an interest intermediation row not to send a net box and rise to fall along with the reservoir water level when it's necessary, recuperate the net box to water deeply feat position.Five, put steady reasonable to keepThe putting of reasonable keeps density, can maintain good fluid matter;Featly dress up a species, can indirectly recuperate fluid matter, with each other benefit symbiosis, attain water body in of harmonious.Want to make Luo non- fish the farming become to live a rate progress, have to control to put to keep density and go together with to keep fish so much.Current farming method lord if pond farming and net box farming, fish is feater than to mix with Luo non- fish to keep, mainly have the silver carp fish, Mao fish, grass carp and Mao the fish and salt water white Chang etc..Annually spring be water temperature rally determinedly in above 15 ℃ then and at first put the seedling of keeping the winter, the garden pond lord keeps usually each one to put to keep Luo non- fish to grow 1500 tails~3000 tails, mix to keep silver carp Mao fish to grow each 40 tailses at the same time~70 tails make by leading long fluid matter;While mixing with other fishes to keep can the acre put 200 tails~500 tails.The Luo non- fish is in the net box probably the list keep, the lord keep or attire a farming.Fish's growing should take big specification as proper, enter box the specification is usually a tail to weigh 10 grams~50 gram, even take 30 grams as good.Putting to keep quantity should follow fluid matter condition affirmation and dissolve the amount of oxygen is in 3 milligrams/rise above, put to keep density to sign each time square rice water body put to keep 3,000 grams of~20 kgs, the fishkind puts to want to carry on a medicine bath to disinfect treatment punishment before keeping.Is other, continue to grow up along with the fish body, in order to regulate good farming density, headway efficiency, can divide to start to criticize to catch to become available in the market and the round catch a round to put to recuperate water body in of carry amount of fish, keep a good fluid matter premise.Six, sincerely keep various diseases from harmingAt Luo non- fish of in the farming, periodically defend a disease is accomplish a guaranteeing assure of good fluid matter premise.Being similar to usually make use of a calcium oxide to defend a disease is more suitable, because it is general to regulate water of the pH of the body, kill to put out water body in of have Li germ, and probably make bottom mire the Ji fasten to have no machine salt and increase the fatty degree of water body.Rise initial according to the date disinfect, garden pond farming every 10 day~15 day, calcium oxide presses each 15 kgs~the 20 kgs turn water whole pond Qing Xie, monthly once~2 times recuperate pond water pH to the tiny alkalescence, improve garden pond microorganism structure with the living creature product, improvement fluid matter;Switch on to increase oxygen while wanting to match at the same time, make the pH in pond water insist between 7.0~8.0, have no color degree in 25 Li rices~of 30 Li box farming, the epitome hangs the method that bag or hurl feed medicine bait through a medicine and carry on according to the date disinfect to defend a disease, improve a fluid matter premise.Secondly want to strengthen to raise a painting everyday.The persistence day and night cruises a pond, the persistence measures water temperature, air temperature 3 times and measures pH weekly every day and measure 2 times have no color degree.The morning and night is once each to cruise a pond and work well farming daily record;The current regulates fluid matter, the fish after sowing the pond insist pond water present dark brownish green, have no color degree to 25 Li rices~30 Li rices.Wait in the low temperature quarter, usually change water once weekly~change 20% of pond water each time 2 times~30%.In addition want to discover good farming condition, stop harmful living creature of all to get into water body.The feeling for you to see this article is:。
