Abstract
The invention relates to a gastropod collecting device. The device comprises a baffle, and a plurality of brackets arranged on the baffle; a collecting tank filled with collecting liquid is formed in the brackets, wherein the collecting liquid is a neutral inorganic slat solution; a salt belt is arranged on the baffle and positioned above the collecting tank; the height difference between the upper side edge of the salt belt and the upper side edge of the collecting tank is more than 50cm. According to the device, the action features of gastropod can be fully utilized; gastropod crossing the baffle can be collected while preventing the gastropod from escaping and dispersing; the individual entering the collecting tank can be basically kept in non-action state through the collecting liquid, in order to be handled after concentrated collection.
Description
Technical field
The present invention relates to a kind of animal collection device, be specifically related to a kind of gastropod mollusc gathering unit.
Background technology
Gastropod be in Mollusca (Mollusca) distribution the widest, belong to kind of a maximum guiding principle, in the animal kingdom next in number only to insect, dwell the free living of creeping in the major part battalion end.Gastropod comprises the Pomacea canaliculata of the Prosobranchiata that we are familiar with, round river snail, Bao, the shell slug of rear gill class, cowfish, the snail, slug etc. of lung snail.Gastropod mollusc life habit is various, and the existing aquatic Lu Sheng that has again, aquatic is divided into again fresh water and two kinds, seawater.In feeding habits abdominal foot roughly the same sample differentiate multiple carnivorous, phytophagy and omnivorousness kind.The harm of phytophagy kind to agricultural production is wherein huge, if Africangiant snail, slug, Pomacea canaliculata etc. are all global pernicious pests.Many gastropod molluscs also threaten human health, and therefore preventing and reducing natural disasters is a long-term job, and current control policy is " put prevention first, prevent and treat combination ", and the therefore monitoring of development environment friendly, control appliance are an important job.Next is that scientist finds that mollusk has adaptability comparatively widely to global environmental change in recent years, and correlative study becomes focus, and the research about gastropod mollusc rapidly increases, particularly urgent to the demand of field investigation, harvester.
Gastropoda animal health is divided into head, foot, internal sac and outer embrane 4 part.Its mesopodium be flat, broad, be rich in muscle matter, be suitable for the locomotive organ of creeping, the kind creeped in most of ground or the bottom, promote health with the contraction of muscle of foot and advance.Nervous system gastropodous comprises brain, foot, side, dirty 4 to basic neuromere.Wherein pedal ganglion (pedal ganglion) is arranged in foot middle part muscle, the motion of domination foot, and has nerve cord to be connected with cerebroganglion.Foot tool pedal gland, be unicellular mucous gland, pedal gland plays an important role in the motion of the kind had.Although mollusk locomitivity is more weak, the dark moist hidden environment of numerous species happiness, hide by day and come out at night, monitoring, control still have inconvenience, therefore can according to its physiology, ecosystem characterization and movement characteristic design gathering unit.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art part and a kind of gathering unit that both can prevent gastropod mollusc escape from can collect the gastropod mollusc of escape is provided.
For achieving the above object, the technical scheme that the present invention takes is: a kind of gastropod mollusc gathering unit, and comprise baffle plate and multiple support be located on baffle plate, described support is provided with feeder, described feeder is built with collection liquid, and described collection liquid is neutral inorganic solution; On described baffle plate, be positioned at above described feeder and be provided with salt band, the difference in height of described salt band top edge and described feeder top edge is not more than 50cm.
In gastropod mollusc gathering unit of the present invention, described baffle plate is used for fixing gathering unit as supportive body, and described support is used for fixing feeder, and support and feeder are easy to be separated and reset.When using gathering unit of the present invention, if main purpose is to collect gastropod mollusc, then the height of baffle plate is unsuitable too high; If main in case be diffused as object, then suitably should improve height of baffle plate.
Salt band of the present invention refers to the crystalline particle attachment zonation of salting liquid, and salt band can prevent gastropod mollusc from escaping, and the individuality that the collection liquid below salt band can guarantee to enter feeder keeps inactive state to wait for unified collection post processing substantially.Salt band of the present invention and collect the composition of liquid and can be the same or different, but its main component must under general environment condition stable in properties, not with the H in air
2o, CO
2etc. reacting, and salt particle in atmosphere not easily water suction dissolve.
As the preferred embodiment of gastropod mollusc gathering unit of the present invention, described baffle plate is rectangle, and the height of this baffle plate is 20 ~ 100cm, length is not less than 40cm; Described feeder is the semicolumn bodily form, and the length of this feeder is identical with the length of described baffle plate, the degree of depth is 5 ~ 15cm.The baffle plate of this specification is convenient in the wild or field uses, and can flexible assembling as required, the too short effect not having collection of baffle plate.
As the preferred embodiment of gastropod mollusc gathering unit of the present invention, described baffle plate is plastic material.The baffle plate of plastic material is light, durable and be easy to fixing.
