Abstract
The utility model belongs to the field of aquaculture equipment and relates to a floating net cage for parent shellfish aquaculture. The floating net cage comprises a frame, a netting, float balls and reinforcing ribs. The frame is in a rectangular structure formed by connection of PVC (polyvinyl chloride) pipes, bends and tees and used for supporting the netting. The netting is a rectangular net cage without upper top face when expanded, specifications of the netting and the frame are identical, the netting is fixed into the frame, the absent upper top face of the netting is positioned at the top end of the frame to enable the net cage floating in water to be open at the top end, the float balls are fixed onto four pipes at the top end of the frame in the rectangular structure, and the reinforcing ribs are fixed at the bottom of the frame. The floating net cage is used for parent shellfish aquaculture, the net cage is capable of floating on water to enable parent shellfish aquaculture in the floating net cage, and parent shellfish can be distributed on one face, with large area and the reinforcing ribs, of the net cage to make better use of high-quality baits and water on the surface layer. Therefore, using floating net cage can improve survival rate in parent shellfish aquaculture and accelerate maturation.
Description
Technical field
The utility model belongs to field of aquaculture devices, relates to particularly a kind of close shellfish cultivation floating net cage.
Background technology
During general shellfish parent shellfish is cultivated, most of cylinder mould that is similar to sea area scallop culture mode that adopts cultivates, cylinder mould be 8-12 layer not etc., hanging on close shellfish with bamboo pole cultivates in pond, the residual bait of scallop and excreta etc. directly residue in Chi Shuizhong, residual bait, ight soil and aging algae etc., under Action of Gravity Field, sink to the bottom in pond.At the bottom of the organic matter sedimentation basins such as a large amount of excretas, residual bait and aging algae, rot to decompose and produce a large amount of harmful substances, cause close shellfish to cultivate pond bottom water body and worsen, this kind of close shellfish type of rearing bottom parent shellfish lethality is higher, causes kind of a shellfish loss.Simultaneously, this kind of close shellfish type of rearing is inconvenient to observe close shellfish, while observing close shellfish, the about 4-5 cage parent shellfish hanging on whole bamboo pole all need to be mentioned, be about to the close shellfish of breeding, have similar effect of drying in the shade in the empty stimulation of cultivation this dew of later stage, easily cause premature labor, the miscarriage etc. of close shellfish, make close shellfish in the ripe ejaculation of just partly laying eggs of sexual gland incomplete development, cannot obtain high-quality fertilized egg in enormous quantities, cause damage.Close shellfish, the especially scallop of cylinder mould cultivation, easily interlock mutually between individuality, due to the cultivation situation of observation scallop that can not be real-time, cannot be in time by interlock scallop separately, cause close shellfish loss.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of close shellfish cultivation floating net cage, close shellfish is cultivated in floating net cage of the present invention, so that close shellfish is good utilisation top layer high-quality bait and good water quality more, solve the series of problems existing in existing indoor close shellfish cultivation, improve the survival rate that close shellfish is cultivated, promote gonad development.While observing close shellfish gonad development situation, the mobility of floating net cage is good, and can pick and place separately some close shellfishes, prevents from observing in the process of close shellfish close mytiliform is become to reveal empty stimulation, causes premature labor, the miscarriage of part parent shellfish.Meanwhile, use net cage of the present invention to carry out close shellfish cultivation and can effectively prevent close shellfish interlock, can find in time interlock parent shellfish and separate, reduce the loss causing because of interlock.This device is made simple, and it is simple and easy, convenient, with low cost to use, and has very strong practical value.
The utility model is achieved by the following technical solution:
A kind of close shellfish cultivation floating net cage, this net cage comprises framework, etting, ball float and reinforcement; Described framework is the rectangular structure being formed by connecting by pvc pipe, elbow and threeway, be used for supporting etting, it after etting opens, is a cuboid net basket that lacks end face, the specification of etting is identical with the specification of framework, etting is fixed in framework, and the upper end face that etting lacks is positioned at framework top, makes net cage float on top time waterborne and opens wide, ball float is fixed on four pipes on rectangular structure framework top, and reinforcement is fixed on the bottom of framework.
Further, described reinforcement is 4, is equilibrated at respectively length sides and the width edge of framework, and is uniformly distributed.
Further, the pvc pipe that described framework is 1-1.5m and 30-50cm by length forms.
Use principle of the present utility model: use this device in close shellfish cultivating process, make net cage can float on the water surface, by parent's shellfish culture in floating net cage, be distributed in the one side that floor space is large and weld reinforcement, and avoid pushing, so that close shellfish is good utilisation top layer high-quality bait and good water quality more, described etting is fixed in framework, in order to prevent that shellfish from runing away or spilling.
The utility model beneficial effect compared with prior art:
(1) net cage of the present invention is made simple, easy to use, workable.
(2) invention net cage of the present invention all adopts the key of PVC material to be welded, and material price is cheap, and cost of manufacture is lower.
(3) in use, close shellfish can make full use of the high-quality bait in the water body of upper strata to invention net cage of the present invention, very good to the accelerating effect of close shellfish, has very strong use value.
(4) can effectively prevent close shellfish interlock, and can find in time interlock parent shellfish and separate, reduce the loss causing because of interlock.
(5) while observing close shellfish gonad development situation, the mobility of floating net cage is good, and can pick and place separately some close shellfishes, prevents from observing in the process of close shellfish close mytiliform is become to reveal empty stimulation, causes premature labor, the miscarriage of part parent shellfish.
Accompanying drawing explanation
The structural representation of Fig. 1 net cage of the present invention: 1 framework, 2 ettings, 3 ball floats, 4 reinforcements.
The structural representation of Fig. 2 framework of the present invention.
Embodiment
Come by reference to the accompanying drawings structure content of the present utility model to be further explained below by embodiment, but protection domain of the present utility model is not subject to any pro forma restriction of embodiment.
Embodiment
A kind of close shellfish cultivation floating net cage, as shown in Figure 1 and Figure 2, this net cage comprises framework 1, etting 2, ball float 3 and reinforcement 4; Described framework is the rectangular structure being formed by connecting by pvc pipe, elbow and threeway, be used for supporting etting, it after etting opens, is a cuboid net basket that lacks end face, the specification of etting is identical with the specification of framework, and etting is fixed in framework, and the upper end face that etting lacks is positioned at framework top, making net cage float on top time waterborne opens wide, ball float is made with foam, is fixed on four pipes on rectangular structure framework top, and reinforcement is fixed on the bottom of framework.
