Abstract
The invention relates to a method for collecting bivalve zooplankton larva and applied seedling collecting apparatus. It employs conical bolting silk mesh bag of 150-350 order, and seedling collecting apparatus comprising water inlet pipe, outlet pipe, and polyvinyl chloride plastic round bottom board, water pump, and pipeline connected water pump and seedling collecting apparatus, sea water is discharged from seedling culture pond through bolting silk mesh bag, and the larva are gathered in bolting silk mesh bag. The invention employs water pump to discharge water during seedling gathering automatically, overcomes shortcomings of water level reduction and mesh of bolting silk mesh bag clog during traditional water discharging course with siphon, and the water flowing velocity is small, the larva move to end of mesh bag gradually which avoids mutual crash and injury.
Description
Technical field
The present invention relates to aquaculture method, particularly a kind of Bivalve floating larvae collection seedling-growing method.
Background technology
At present, the artificial breeding of bivalve shellfish is flourish in China, and in the artificial breeding process, because reasons such as water quality deterioration, larva diseases, it is an operation that often runs into that the collection seedling falls the pond.The collection seedling-growing method is siphonage at present: floating larvae in the nursery pond is reinstated siphon pipe with seawater one discharge, at siphonal water outlet end bushing screen tulle bag or placement collection seedling net cage, seawater flows out by the bolting silk net, and larva is then stayed in bolting silk mesh bag or the net cage.But this method has a lot of shortcomings: at first, a large amount of larvas are long-time collision mutually under the effect of current in mesh bag or net cage, can cause the damage of larva; Secondly, along with the decline of the nursery pond water surface, the speed of discharge water is more and more slower, so conventional collection seedling operating efficiency is very low.Though it is the grow seedlings method of water quality of a kind of thorough improvement that the collection seedling falls the pond, above shortcoming has seriously limited its frequency of utilization.
Summary of the invention
The purpose of this invention is to provide a kind of larva Bivalve floating larvae collection seedling-growing method efficiently again that neither damages, overcome the deficiency of original collection seedling-growing method.
Method of the present invention is: make collection seedling device with 150 orders～350 order conical screen tulle bags, water inlet pipe, outlet pipe, igelite round bottom plate; The outlet pipe of collection seedling device is connected with water pump by pipeline, and will collects the seedling device and be placed in the nursery pond; Switch on the pump, seawater is discharged from nursery pond after filtering by collection seedling device bolting silk mesh bag, and larva then is collected in the bolting silk mesh bag of collection seedling device.
The present invention adopts initiatively draining of power water pump when the collection seedling, with the slow shortcoming of drainage speed that the nursery pond water surface reduces, bolting silk mesh bag mesh obstruction causes, improved operating efficiency when having overcome traditional siphonage draining; Water velocity by collection seedling device bolting silk mesh bag is less, and larva is moved to the end of bolting silk mesh bag along same direction gradually with current, the damage of having avoided the mutual collision between larva to cause.

Fig. 1 is the profilograph of collection seedling device.
Embodiment
The present invention collects the seedling system and is made of the pipeline that collection seedling device, water pump and connection collect seedling device outlet pipe and pump intake; As shown in Figure 1, collection seedling device is made up of 150 orders～350 order conical screen tulle bags, water inlet pipe, outlet pipe, igelite round bottom plate, conical screen tulle bag 1 places in the water inlet pipe 2, the inlet end outside one port that the mouth of conical screen tulle bag 1 turns up and is wrapped in water inlet pipe 2, and the certain elastoplast rope 5 of apparatus is tightened, outlet pipe 3 is contained in the other end of water inlet pipe 2, and igelite round bottom plate 4 is equipped with in the another port of water inlet pipe 2, and outlet pipe 3 is contained in and partly is evenly equipped with aperture 6 in the water inlet pipe 2.During the collection seedling, will collect the seedling device and be placed in the nursery pond, and switch on the pump, seawater is discharged from nursery pond by aperture 6, outlet pipe 3, pipeline, water pump after filtering by collection seedling device bolting silk mesh bag 1, and larva then is collected in the bolting silk mesh bag 1 that collects in the seedling device.The water inlet pipe 2 and the outlet pipe 3 of collection seedling device are generally pvc tube, and water inlet pipe 2, outlet pipe 3, igelite round bottom plate 4 cohere fixing successively with epoxy resin; The bottom of conical screen tulle bag 1 places the inside of water inlet pipe 2, and the other end wraps in the outside of water inlet pipe 2 to turning up, and is fixed with plastic ties 5, and outlet pipe 3 is provided with aperture 6.When seawater larva when water inlet flows into collection seedling device is moved to the end of conical screen tulle bag 1 gradually along the direction of current, and finally be filtered the end that is collected in bolting silk mesh bag 1; Seawater is then discharged nursery pond by bolting silk mesh bag 1, aperture 6, outlet pipe 3, pipeline, water pump.When the collection seedling, adopt initiatively draining of power water pump, with the slow shortcoming of drainage speed that the nursery pond water surface reduces, bolting silk mesh bag mesh obstruction causes, improved operating efficiency when having overcome traditional siphonage draining; Water velocity by collection seedling device bolting silk mesh bag is less, and larva is moved to the end of bolting silk mesh bag along same direction gradually with current, the damage of having avoided the mutual collision between larva to cause.
