Abstract
A Sepiella maindroni de Rochebrune larva collector which is provided by the utility model comprises a net, a frame and a control rod, the net (2) and the frame (1) form a container with a fixed shape, a floating device (3) is mounted on the upper part of the frame, the front side of the container is provided with an opening, moreover, a tongue-shaped net (4) is forwardly extended from both sides and the bottom of the opening, and the control rod is connected with the front edge of the forward extension of the net. Compared with the prior art, the Sepiella maindroni de Rochebrune larva collector utilizes the physiological characteristics of Sepiella maindroni de Rochebrune and uses the tongue-shaped collecting net to guide larvae to gather into the collecting frame, consequently, the disturbance on the larvae is decreased to the minimum, convenience is provided for the culture of the Sepiella maindroni de Rochebrune larvae in different ponds, the affection on the Sepiella maindroni de Rochebrune larvae is decreased, and the survival rate of Sepiella maindroni de Rochebrune culture is increased.
Description
Technical field
The utility model relates to a kind of Sepiella maindroni young gathering unit, a kind of in Sepiella maindroni seedling raising process when the cultivation of point pond, prevent squid larva ink-jet death for assign to the examination of other pond from the high seedling pond of density supporting, improve cultivating survival rate and the device that uses.
Background technology
Sepiella maindroni (Sepiella maindroni de Rochebrune), is commonly called as inkfish, order fish etc., and tasty mouthfeel giving off a strong fragrance, has very high nutritive value, is very popular ocean water product.Because overfishing and marine environment change, cause the eighties in last century Sepiella maindroni resource to start slump of disastrous proportions, be close to so far disappearance.For repairing Sepiella maindroni resource, meet consumers in general and look forward to the Sepiella maindroni an urgent demand of having, since 2003, China has carried out the artificial breeding of Sepiella maindroni and has studied and obtain successfully.Juvenile stage in Sepiella maindroni seedling raising process exists and is affected by the external environment and the phenomenon of ink-jet death, particularly, in point pond incubation, as misoperation can cause large quantities of death, affects survival rate of seedling.Described point of pond process is with a kind of Sepiella maindroni young gathering unit, the young to be assigned to the process that other culture pond is cultivated to reduce density from high density pond, when described device designs unreasonable, will ink-jet while making Sepiella maindroni feel to be on the hazard, because young vitality is lower, it is fatal that the vitality that its ink-jet causes runs off.The gathering unit in the past using is blanket net, has the bag that a net sheet is made to be arranged on annular framework, also has a control stick to be connected with annulus.When use, squid larva is drawn in again and move on to together in another pond with the bucket networking band young in water with blanket net, because this device easily causes very large agitation to the young in use, careless slightlyly just can cause large quantities of death.
Summary of the invention
For above-mentioned the deficiencies in the prior art, the utility model is exactly will be according to the physiological ecological habit of Sepiella maindroni, the technical characterstic of cultivating in conjunction with in Sepiella maindroni seedling raising process point of pond, provide a kind of is to prevent squid larva ink-jet death, improve the Sepiella maindroni young gathering unit that uses of cultivating survival rate by moving to from the high culture pond of density that new culture pond divides while supporting in Sepiella maindroni seedling raising process, to improve the Sepiella maindroni economic benefit of producing of growing seedlings.
A kind of Sepiella maindroni young gathering unit that the utility model provides, there are net sheet, framework and control stick, described net sheet and framework form a figurate container, described framework upper is provided with buoyant device, described container front openings, and the both sides of described opening and have below net sheet to extend to be forward ligule, described control stick and net the sheet forward leading edge of extension are connected.
A kind of Sepiella maindroni young gathering unit that the utility model provides, shape is as dustpan, and its rear portion is the collection frame that has frame supported, anterior be the collecting net without bone.This device has the collection frame of a dustpan shape and the collecting net of ligule, and collecting frame has buoyant device to make in its half potential water.When operation, move ahead under water by control stick traction collecting net leading edge, just the young in pond can be drawn in and collect in frame, reach after some wait the young of collecting, be that pull-up collecting net is enclosed in the young to collect in frame, connecting device band water with containers such as buckets again picks up and puts into new culture pond, emit the young and cultivate, reach the object in point pond.
Compared with prior art, the utility model has utilized Sepiella maindroni physiology characteristic, concentrated to collecting frame with the collecting net guiding young of ligule, to drop to minimum to the agitation of the young, cultivate and provide convenience for the Sepiella maindroni young point pond, reduce the impact on squid larva, improved cuttlefish survival rate of seedling.
Describedly extend and be ligule net sheet edge a nylon rope is set forward, so that can catch net sheet while connecting control stick.
Describedly extend forward the height of water level that the length that is ligule net sheet is greater than culture pond, make collecting net leading edge can and the end, collect in frame to the seedling in whole culture pond vertical height is once collected.But as will before collections, first High Density Cultivation pond be carried out draining reduction water level, can make the collecting net can be shorter.
Brief description of the drawings
Fig. 1 is the schematic diagram of the utility model one embodiment, in figure: 1-framework, 2-net sheet, 3-buoyant device, 4-ligule net sheet;
Fig. 2 is that the utility model one uses view, in figure: 3-buoyant device, 4-ligule net sheet, 5-collects frame, the 6-water surface, at the bottom of 7-pond, 8-control stick.
Embodiment
1, as shown in Figure 1, have a rectangular frame 1, the stainless steel square tube that framework is 0.5cm by the length of side is welded, long 100cm, wide 50cm, high 30cm.Top, framework front side is without connecting rod.All using 80 object bolting silks in the end, rear side and the left and right sides of stainless steel frame is that net sheet 2 is coated, forms and collects frame.Wherein, the etting of the end and the left and right sides extends to form forward ligule net sheet 4 and forms collecting net, and ligule net sheet development length is that lower in echelon gradually 150cm and the left and right sides.The edge of collecting net part bolting silk is sewed with a nylon rope, to strengthen the fastness of ligule net sheet.At the each cylindrical keg float of fixing in the third two sides, left and right and top below of collecting frame, make to collect frame suitable for reading higher than the water surface.
When use, as shown in Figure 2, device bubbles through the water column 6 with buoyant device 3 by collection frame 5, control stick 8 use hooks are connected with collecting net (ligule net sheet) 4 leading edges, by collecting net leading edge press at the bottom of pond 7 and traction move ahead, make to collect the young in the whole vertical height in frame front and be collected into by collecting net guiding to collect in frame.
2, have a cylindrical frame, framework silk is that the stitching of net sheet is coated cylinder and rear side, and front side bolting silk extends forward, and extension upper opening the contraction of oblique front end bottom, forms ligule net sheet.It is buoyant device that framework is crossed each rectangular foam of fixing on the bus of horizontal radial line.Control stick front end is connected with ligule net sheet front end through ring.
