Abstract
The invention provides a seasonal swimming crab breeding method and a carrier using a mussel breeding stringer, and relates to the technical field of crab breeding and particularly relates to a seasonal swimming crab breeding method and a carrier using the mussel breeding stringer. The method uses that the time of breeding the mussels is long, growing period and rest period are seasonally fixed, breeding area and density are changed once in a fixed season, and the density proportion of the growing period and the rest period is 2:1-10:1. Swimming crabs are bred in the vacated area. The mussel is bred on the outer lane because the mussels prefer wind wave and ocean current and the swimming crabs are bred in the inner lane and a double bearing rope of a breeding carrier of the swimming crabs is hung on the main cable of the breeding ground stringer. The method takes advantages of swimming crabs catching mussel breeding ground stringer and takes advantages that mussels prefer the wind wave and the ocean current, the swimming crab which is bred on the outside lane is bred uniformly in the inside lane inside the anti-storm and no-damage carrier and the mussel stops the wind wave, restoring the natural growing environment of the swimming crabs, effectively lowering breeding risk, preventing disease and producing high profit.
Description
Technical field:
The present invention relates to the crab cultivation technical field, be specifically related to a kind of ground, mussel culture purlin seasonality of utilizing and increase foster swimming crab method and carrier.
Background technology:
Sea crab is fast because of its growth, and specification is large, and cream fat meat is many, and tasty mouthfeel is of high nutritive value, and liked by consumers in general.Yet the cultivation of sea crab is not a simple tractable thing.Traditional swimming crab cultivates ground away from the ground method of fishing for; mostly adopt and enclose pool cultivation, and enclose not possess on the pool and fish for ground water quality and fresh bait, also do not protect facility in the growing environment of crab; and the inequality of ingesting causes the lethality of crab girth of a garment inequality and disability very high.Make simultaneously its quality bad, crab meat is delicious not, thereby greatly reduces the poultry feeders income.
Summary of the invention:
The purpose of this invention is to provide and utilize ground, mussel culture purlin seasonality to increase foster swimming crab method and carrier, it utilizes swimming crab and fishes for ground, mussel culture purlin, ground, utilize the mussel growth to like stormy waves ocean current feature, cultivation cultivates at inner ring without injuring evenly to throw something and feed in carrier in wind wave resistance the outer ring swimming crab, allow mussel remove to stop wave, the swimming crab spontaneous growth environment that not only reduced also has pin ground reduction cultivation risk, has also effectively prevented the generation of disease, and the output profit is high.
In order to solve the existing problem of background technology, the present invention is by the following technical solutions: it utilizes the mussel culture time long, vegetative period and resting stage are seasonal fixing, do cultured area and variable density in fixing season, vegetative period and resting stage, Distance Density ratio 2:1-10:1 vacated oceanic area hanging culture swimming crab, utilize mussel growth to like the stable breeding outside of stormy waves and ocean current to grow, swimming crab cultivates at inner ring, and the two bearer cables of swimming crab cultivation carrier are hung on the landlord's rope of cultivation purlin.
Described hanging culture carrier comprises plastics large bamboo or wicker basket 1, etting overcoat 2, hanging rope 4, the stressed circle 5 of plastic shape-forming, zipper door 6, around rope yarn 7 and crab nest 9; Several plastics large bamboo or wicker basket 1 spacer sleeves are located in etting overcoat 2, and the middle and lower part of every layer of plastics large bamboo or wicker basket 1 with etting overcoat 2 by being fixedly connected with around rope yarn 7, the interior survey of etting overcoat 2 top is provided with the stressed circle 5 of plastic shape-forming, etting overcoat 2 tying places, top are provided with hanging rope 4, be provided with zipper door 6 on etting overcoat 2 between the plastics large bamboo or wicker basket 1 of being separated by up and down, be provided with crab nest 9 in plastics large bamboo or wicker basket 1.
Several plastics large bamboo or wicker baskets 1 in described etting overcoat 2 adopt the stacked setting in interval, and the quantity of plastics large bamboo or wicker basket 1 is 1-5, and etting overcoat 2 is latticed with several plastics large bamboo or wicker baskets 1, has good water penetration, guaranteed again simultaneously that swimming crab in the marine environment growth, is not subjected to the interference of extraneous species.
The hanging rope 4 on described etting overcoat 2 tops is two, and two hanging ropes 4 adopt to intersect and separately be banded on the landlord's rope of purlin, and its stability is good, effectively reduces stormy waves carrier is fluctuateed in seawater.
The stressed circle 5 of described plastic shape-forming is shaped as circle, good styling plays in 1 the superiors at the plastics large bamboo or wicker basket, simultaneously the whole carrier of etting overcoat 2 is played stressed uniform effect, the plastics large bamboo or wicker basket 1 and lower floor's shape and the space that have kept simultaneously the upper strata also reduce whole carrier water outlet and reach the seawater resistance.
Described crab nest 9 is opening shape container, and the quantity of every layer of crab nest 9 can arrange 1-4 according to demand, is provided with silt in each crab nest 9, and it can reduce the original living environment of swimming crab, when natural marine site raises the wind, stablize its great role of the silt weight in every layer of crab nest 9 to carrier.
Described zipper door 6 is plastic material, and the quantity of zipper door 6 is decided according to the quantity of crab nest 9, and when 1 li crab nest 9 quantity of the plastics large bamboo or wicker basket of every layer are above greater than two, its zipper door 6 is two, it can for a long time as for not being corroded in seawater, be convenient to the interior swimming crab of crab nest 9 is passed in and out, throws something and feeds, clears up and safeguards simultaneously.
The quantity of the crab nest 9 in described every layer of plastics large bamboo or wicker basket 1 is two and is provided with permeable plastics filter 8 between each crab nest 9 when above, and two jiaos, plastics filter 8 top is provided with the rubber rope 10 of hanging plastics filter 8.
The etting overcoat 2 upper ends outsides of described each carrier are provided with two and stop steady cotton rope 3, and stop steady cotton rope 3 one end connecting hanging lanyards 4, the other end connect the stressed circle of plastic shape-forming 5 times any one, stability is better under water to make it.
Described feeding method adopts bait feeding: namely begin after swimming crab is put to throw something and feed, utilize local unique food resource, small fish is caught in mussel and sea, mixed hello swimming crab, during cultivation the kind of bait and daily ration, feeding quantity be according to the growth cycle feeding habits of swimming crab and appetite and decide, and the stage of throwing something and feeding was divided into for two stages: first paragraph is fattening period, and small fish is main, mussel is auxiliary, and 1 the ear material quantity of throwing something and feeding was the 5%---35% of swimming crab body weight in 1--5 days; Second segment was thrown something and fed 1 time for educating the cream phase in mussel and the similar 2--10 of small fish ratio days, and quantity is crab body weight 3%-25%.
The present invention is conducive to the ecological economy pattern of Sustainable Development of Marine Economy, can improve to greatest extent unit marine site cultured area and cultured output, is not only applicable to the cultivation of mussel and swimming crab, also applicable comprehensive three-dimensional culture with other etc.; Developing ecology cultivation formula weakens the pollution to water body; Implement marine ecosystem propagation pattern, by controlling the environmental pollution in marine site, throw in the measures such as artificial fishing bank, improve the marine ecosystem environment, the intensity of controlling fishing simultaneously and fish for kind, artificial releasing's seedling, regulation and control marine site biology community structure makes the fishery output sustainable growth of economic system.
