The Xiao section(Octopodidae) is biggest one section in a foot key link, general name for octopus.The head of octopus two side eye the path is smaller, before the head and around has 4 rightnesses of wrist, the length is close by or doesnt wait.Spread all over to circulate each waters of world, there are 140 kinds around.Big part is a neritic sex category, also have most likely deep sea category.Mostly have two lines of suckers on the wrist of Xiao section, the category list having goes sucker.Right side or left side 3 wrist caulises turn.The top of wrist transforms and calls carry a machine, didnt touch wrist.Brain egg circular, smaller, dont have meat fin.Inside the hull deteriorate and remain two up the small hull needle just in the back two sides, dont have to give out light a machine.The female body has a rightness of fallopian tubes.The initial camp bottom stays career to crawl to crawl along in the bottom of sea, can also rely on funnel to spray aqueous of the pair influence gradually long-last parade in first floor sea water.Have short Ju leave of grow and more the winter Hui visit temperament, with the lobster, shrimp Gu, crab, molluscs and bottom stay fish for eat.Oneself often hunts to eat object for shark, and sea eel.etc.The margin category of octopus creates amount of egg to differ very big, from several thousands of go to ten remainings ten thousand not etc., the ovum cent criticizes immature, divide to criticize to create, create of ovum-like in shape like grain of cooked rice, often become Sui connect together.The true Xiao of Hong ditch in the south of China and the short Xiao of northern coasts all having doesnt necessarily produce quantity, octopus in addition to being edible outside, still have already increased the blood benefit spirit and refrain from rash action to living a reforming of muscle on the medicine.A, biology special feature and artificial farmingThe octopus is a temperate zone mollusk.Adapting to water temperature doesnt can be lower than 7 , sea water specific weight 1.021 the most fitting and proper, the condition of low salt degree will die.The bottom quality of sea area had better be a gravel district, the water temperature can produce egg in above 12 anniversary, all of the Zi fish grow 3 younger sisters to order about after hatching from eggs, can absorb a large plant plankton but growth, 45 day after all grow to reach l 0-13 younger sisters, sink Be declined to a bottom of sea camp bottom to stay to subsist.The octopus can accept a net box farming(the 3.94 mXs 1.82 mXs 0.9 ms, the mesh grows than the fish individual small, need to add a net cover to prevent octopus from escaping.Octopus much in the wave rather the farming inside the bay of Jing, conform to of water temperature is 15 one 23 s, usually under the circumstance, similar usually in spring a summer(6, July) and spring(l 0-12 months) farming.Grow seedling:The octopus seedling that is caught by the cage is the most practical, while the net catches may also to use from the bottom Yi.Put amount of seedling to follow a water temperature text flowing water circumstance to have to discriminate.Applied large net box each l signs a square the rice put to keep seedling to grow a 36-42 kgs, small scaled net box each l signs square the rice put to keep seedling to grow 25-30,000 grams.Should put to resist a batch of seedlings to grow for keeping seedling from growing mutual massacre, seedling after growing should at the Yan Yu put into a Gou box is secure.The bait anticipates:Can throw in lowly small miscellaneous fish of price and molluscs, frozen of the small miscellaneous fish can also throw in, but must be fresh delicate of, while destroying bait much can gradually reduce to probably stop throwing bait l on the 2nd is good, destroy bait will constitute a fluid matter pollution, suppose stop to throw bait will constitute to struggle each other for more than 3 days.The water temperature absorbs action not to dilimit rules in 13 domination, the water temperature below 7 octopus doesnt absorb.Become to live a rate;Adopt the cage catches of the seedling grow a Dian end 2 month farmings become live to lead to 70% one 80%, application snare the seedling catching to grow live rate about order about in 50%.The seedling kind puts to keep in the net box, the birthrate reaches to 20% one 30% on the 15th, and hereafter the death rate cuts down gradually.Through 15 day farming, is greatly divided into octopus and moderate three kinds of small specification cents to keep in the net box of rift.Make to clean a net box for 15 days once in spring, Mid-Autumn Festival, the winter days cleans once in 30 days.Two, the octopus reduce the heat to protect to live a methodThe octopus can adopt a kind of benefit after sowing seeds conveyance to then make octopus reduce the heat to protect a live method again:Square one is will apprehend behind of live octopus to pick out individual strengthen Jian, Ti go to harm with be unsuited to the octopus of specification.The policy that is attained by octopus oneselfs mental activity to throw away sediment and glues the dirt in liquid and sucker while willing select good octopus to put the 0.5 ls in the clean sea water.While still canning not to cannot compare with to sweep can not by hand and any device break a miscellaneous articles or objects on fish body, should put dirty water and make change detergent sea water again decontamination, should not dash forward octopus while filling with water, have no necessary hand and another apparatus ground to touch octopus as far as possible in the whole process.The octopus catching from the ocean after soaking the fresh water can also survive a time, but once soak the octopus of salt water and cooled off dormancy very difficult become to live behind.The second step is:Put into sea water with the health plastics bag ice, make the temperature of sea water decline to approach 0 , the octopus is placed in dormancy status at this time.The octopus that immediately after will be placed in dormancy appearance puts a person plastics bag in, take part in 20% water temperature to approach 0 pickle 臜 sea waters, the Chong goes into oxygen and ties to seal co
