Abstract

The utility model relates to a small sized net cage in intensive fish raising pool, which comprises a box and a matched device. The small box is a box with the top open at the size of three meter multiplies three meter multiplies two point five meter; the net is forty to sixty reticulation or one point five centimeter reticulation; the upper edge of the box is provided with a tie rope; the upward side of the bottom is provided with a material table and an oxygen rising carbon head. The matched device comprises a fixed frame, an automatic aerator, a pipe and a pump; a standing post fixed in the bottom of the pool and a vertical beam positioned on the top of the standing post form the fixed frame which is matched with the size of the box; the box is connected with the frame through the tie rope; and the pipe connected with the automatic aerator and positioned in the lower side part of the beam is connected with the oxygen raising carbon head. The utility model can be used for raising the spray, induce and breed the fry and raise the commodity fish; and the utility model can enhance the product efficiency of fish.

Description

The carerful pond-reared fish small-sized net cage

The utility model relates to breed fish equipment and equipment.

At present, breed fish and mostly adopt whole pool to support a kind of fish or raise together with the fish of several different life habits simultaneously; For the very big lake of the water surface, reservoir etc., then purse seines that adopt are divided into some small sizes waters or employing fish culture in net pen more.

All use scaffold and sinker that the location is set in view of the net cage that on big waters, uses, be provided with the material platform in the net cage and supply with bait by the bait throwing in machine; Net cage central authorities are provided with aerator.This fish culture cage has bait utilization height, advantage that yield per unit area is high; But owing to be subjected to structure and size restrictions, this large-scale net cage can not be used for small size pond, narrow water channel river bend etc. effectively, it is more single especially to culture the fingerling class, is difficult to adapt to the changeable market demand; In addition, this net cage is only applicable to the breed of adult fish and marketable fish, can not be used for from parent fish rearing to spray, fingerling is hastened parturition hatching.

Main purpose of the present utility model is, design also provides a kind of carerful pond-reared fish small-sized net cage and supporting with it equipment, make it to be applicable to that the different waters of area breeds fish, in several net cages in a pond, culture several different fishes according to market demand, and can be engaged in from the parent population to the spray, serial factory formula breeding that fingerling is hastened parturition hatching, form the production line of seriation, diversification of varieties.

For achieving the above object, the utility model adopts following design:

Carerful pond-reared fish small-sized net cage of the present utility model comprises breed fish small-sized net cage and corollary equipment; Cuboid skeleton that described small-sized net cage is coupled to by stock and the net sheet that is fixed on skeleton front, rear, left and right, bottom constitute and forms above uncovered net cage, on skeleton, be provided with tether, can be provided with hook on the tether, spacer screen face top is provided with the oxygen increasing carbon head that material platform and 1～3 can be joined with the oxygenation pipeline; Described corollary equipment comprises small-sized net cage fixed frame, aerator, oxygenation pipeline and pump, fixed frame by be vertically fixed on column at the bottom of the pond, be erected at the column top horizontal girder or/and crossbeam constitute, spacing between the longitudinal and transverse beam and small-sized net cage suitable to size in length and breadth, be provided with several vertical connecting columns of evenly arranging on longeron or crossbeam, connecting column is provided with the coupling ring of a pulley or several differing heights; The oxygenation pipeline is laid in longeron or/and the side lower part of crossbeam and joining with aerator, oxygen increasing carbon head respectively.Small-sized net cage is by the rope on it or pulley on hook and the framework connecting column or coupling ring connection.

The size of described small-sized net cage, long by 2.5～3.5, wide by 2.5～3.5, the degree of depth is 2～3 meters; Cultivating the young small-sized net cage net sheet of crow is 40～60 orders, and the net cage mesh of cultivating the parent is 1.5 centimetres.

Reasonability and advantage for clearer understanding design of the present utility model are described below with accompanying drawing now in conjunction with the embodiments:

Fig. 1---small-sized net cage structural representation.

The stationary frame structure schematic diagram of Fig. 2---small-sized net cage.

The connection schematic diagram of Fig. 3---small-sized net cage and fixed frame.

This small-sized net cage (referring to Fig. 1) is, connecting cuboid skeleton and 5 net sheets that are fixed on skeleton front, rear, left and right and bottom 1.4,1.5,1.6,1.7,1.8 of forming by 1.2,4～6 transverse horizontal bars of 1.1,4～6 vertical equity bars of 4～8 vertical bars 1.3 constitutes; The rope that 4 vertical bar top is provided with or become soft hook that connects 1.9 and bone wheel or coupling ring 2.5 on the fixed frame connecting column 2.4 to join is so small-sized net cage can the lift adjustment height, to adapt to different water levels and temperature.The column 2.1, horizontal gird 2.2, the horizontal girder 2.3 that constitute the small-sized net cage fixed frame all are mutually quadrature, and its size and small-sized net cage coupling, neatly also can make full use of the water surface so arrange.Establish the side lower part that flatly is arranged on crossbeam or longeron with the oxygenation pipeline 3.1 that aerator joins, so do not hinder the operation of breeding fish.Be provided with under the condition of the powerful aerator of an EOLO2 type at 766 meter 2 water surface, 1～3 oxygen increasing carbon head 3.2 dissolved oxygen of every case that join with the oxygenation pipeline can reach more than 3.5～4.0 mg/litre, and the unit are amount of breeding fish effectively is improved; Pump is used for producing fine bourn and the photosynthetic bacteria of regularly splashing, and water quality is improved and provides open-mouthed bait for fry; The water inlet of pump and the removable scrubbing flexible pipe that is located at the bottom of the pond are joined, help in time getting rid of fish excreta and bait remnant, promote the growth of fish.

The utility model has the advantages that: 1, can take full advantage of the different waters of breeding fish of area; 2, save bait Material; 3, be conducive to control water quality, reduce the incidence of disease of fish and improve the fish disease curative effect; 4, be convenient to according to the city The field changes to change raises fingerling; 5, be conducive to improve the unit are amount of breeding fish; 6, it can be applicable to from the parent Fish is cultivated the hatching of hastening parturition of spray, fingerling, until the cultivation of marketable fish, for industrial production line provides basic.
