A kind of tandem pond for being used for an age knife long-tailed anchovy ecology breeding, it is related to aquaculture installation, using breeding spand and parent pond, it is characterized in that breeding spand and the pond of parent pond two are adjacent into tandem pond, breeding spand is as seed rearing and prime fish kind culturing pool, parent Chi Zuowei parents cultivate and breeding pond, embedment one is used for the culvert pipe connected among the intermediate isolating pool stalk in two ponds, culvert pipe two-port is wrapped up with leather strap net, parent pond is provided with water inlet, Inlet water is cased with 60 mesh sieve thin,tough silk filtering mesh bags, and breeding spand is provided with discharge outlet, and discharge outlet is blocked with twice.Using connecting, the fry in an age knife long-tailed anchovy parent pond is introduced breeding spand by culvert current in time, in the case where not drawing in the net to catch an age knife long-tailed anchovy parent, realize efficiently separating for knife long-tailed anchovy parent and produced fry, avoid the problem of knife long-tailed anchovy parent kills and devour knife long-tailed anchovy seed, the newly hatched larvae that an age knife long-tailed anchovy parent is produced is efficiently utilized, while carries out seed rearing and obtains the seed yield that higher pond ecological is bred.
Description
Technical field
Aquaculture installation is the utility model is related to, especially a kind of tandem pond for being used for an age knife long-tailed anchovy ecology breeding
The pool.
Background technology
Knife long-tailed anchovy (Coilia ectenes), category Clupeiformes, Anchovy sections, long-tailed anchovy category, is commonly called as hairtail, rough cutter fish, Mao Huayu, beard
Fish, tapertail anchovy.It is distributed mainly on China Huang Bohai Sea and the band of the East Sea one, all maritime rivers such as Liaohe River, Haihe River, the Yellow River, the Changjiang river, Qian Tang
Jiang Junneng is seen, its with fine and tender taste, delicious flavour and it is famous, be the rare migratory fish for enjoying one of " the Changjiang river three delicacies " good reputation
Class.In recent years, because the influence of the factors such as overfishing and the deterioration of the ecological environment, knife long-tailed anchovy resource drastically fail, 2016
Year, the Ministry of Agriculture of China also plan knife long-tailed anchovy be included in protection animal register carried out consultation.But the market demand is growing on and on, very
To the awkward situation having price but no buyers, before and after the Clear and Bright of 2016, the knife long-tailed anchovy market price of three liang or so specifications be up to 7000 yuan/
Jin.The breakthrough and popularization of the artificial breeding technology of knife long-tailed anchovy, and then the industrialization breeding production of the fish is promoted, fishery industry can be promoted
The adjustment of structure, promote fishery synergy, fisherman's increased income.Therefore, before knife long-tailed anchovy has good development as artificial farming new varieties
Scape.
At present, in the mode of reproduction of knife long-tailed anchovy ecology, the later stage is being bred, is being required to draw in the net to remove knife long-tailed anchovy postpartum parent, to keep away
Exempt from parent and prey on knife long-tailed anchovy seed, such as：The Application of Artificial Intelligence mating system and a kind of Coilia ectenes in Yangtze River pond greenhouse of a kind of hairtail parent population
The early breeding method of ecology.But these methods are all based on 2 big specification knife long-tailed anchovys more than age, big specification knife long-tailed anchovy postpartum parent can draw in the net
Operation, but an age knife long-tailed anchovy individual is smaller, constitution is thin and weak, and particularly one age of postpartum knife long-tailed anchovy constitution is weaker, is not suitable for artificial
Operation, meanwhile, found in production practices, the week old knife long-tailed anchovy for having 40-50% participates in breeding in breeding season meeting gonad development, such as
Fruit is not used will waste of resource.Therefore, it is necessary to which a kind of special equipment is safely and reasonably produced using an age knife long-tailed anchovy
Prelarva, separate prelarva and parent.
Utility model content
The purpose of this utility model is to provide a kind of tandem pond for being used for an age knife long-tailed anchovy ecology breeding.
The technical solution of the utility model uses breeding spand and parent pond, it is characterized in that breeding spand and the pond of parent pond two are adjacent
Into tandem pond, breeding spand is cultivated as seed rearing and prime fish kind culturing pool, parent Chi Zuowei parents and breeding pond,
Embedment one is used for the culvert pipe connected among the intermediate isolating pool stalk in two ponds, and culvert pipe two-port is wrapped up with leather strap net, parent
Pond is provided with water inlet, and Inlet water is cased with 60 mesh sieve thin,tough silk filtering mesh bags, and parent pond can not set discharge outlet；Breeding spand is provided with draining
Mouthful, discharge outlet is blocked with twice, and breeding spand does not set water inlet；One 1.5 kilowatts of aerator is respectively set in parent pond and breeding spand.
The advantages of the utility model：Using connecting, the fry in an age knife long-tailed anchovy parent pond is introduced next door by culvert current in time
Breeding spand, in the case where not drawing in the net to catch an age knife long-tailed anchovy parent, efficiently separating for knife long-tailed anchovy parent and produced fry is realized, is kept away
The problem of knife long-tailed anchovy parent kills and devour knife long-tailed anchovy seed is exempted from, has efficiently utilized the newly hatched larvae that an age knife long-tailed anchovy parent is produced, enter simultaneously
Row seed rearing obtains the seed yield that higher pond ecological is bred；Meanwhile it also obtain knife long-tailed anchovy postpartum in age parent warp
Cross cultivate it is recycling.The utility model realizes the bumper harvests of knife long-tailed anchovy seed and adult fish culture.The utility model is easy to operate,
Without the operation to become more meticulous, it is not necessary to receive the training of system, be easy to be accepted and promote.
