Abstract

The utility model discloses a loach breeding barrel which is characterized by comprising an isolating barrel with an upper opening and a lower opening. The isolating barrel is connected with a floating device. The lower portion of the isolating barrel is connected with a loach egg collection mesh bag. The bottom of the loach egg collection mesh bag is provided with an egg outlet which is sealed in a normal state. The loach egg collection mesh bag is a polyethylene net with more than 300 meshes, gradually becomes smaller from the upper portion to the lower portion and is in a funnel shape. The egg outlet is tied up through a rope. The lower portion of the isolating barrel is connected with a mesh bag supporting framework which supports the loach egg collection mesh bag. According to the loach breeding barrel, loaches are limited within a certain range, the fertility rate of the loaches is improved, the survival rate of fertilized eggs is improved, and the fertilized eggs are convenient to collect.

Description

Loach breeding bucket

Technical field

The utility model relates to technical field of aquaculture, is specifically related to a kind of loach breeding bucket.

Background technology

Expansion along with the loach breeding scale, demand to the loach seed increases considerably, seed has become the main restricting factor that can the loach breeding scale enlarge, how to improve fertilization rate and incubation rate that close loach produces the loach ovum, reducing damage namely is its key point, in the existing loach modes of reproduction, mainly contain two kinds of methods of artificial insemination and natural spawning, therefore and because the loach individuality is less, epidermal mucus is many, carries out test-tube labour intensity larger, and the damage to close loach in the operating process is very large, very easily cause close loach dead postpartum, therefore, the seed that is used at present propagating artificially mainly is by close loach natural mating, natural spawning obtains.But the scope of activities of existing loach equipment for breeding loach is excessive, cause loach mating and fertilization rate to reduce, and traditional loach equipment for breeding fertilized egg is in bottom of device, collect fertilized egg inconvenient, also easily ovum is injured during collection, reduce its survival rate, simultaneously because after close loach lays eggs, under hungry situation, the loach ovum of can eating must adopt spacer assembly that close loach and ovum are separated.

The shortcoming of prior art is: the scope of activities of loach is excessive, and the fertilization rate of loach mating is low, collects the fertilized egg inconvenience, does not have the isolating and protecting measure, and close loach easily eats up ovum.

The utility model content

The purpose of this utility model is to provide a kind of can improve close loach fertilization rate, loach survival rate of ovum and the convenient loach breeding bucket of laying eggs of collecting.

For achieving the above object, the technical solution of the utility model is as follows: a kind of loach breeding bucket, its key is: comprise all uncovered isolation buckets of upper and lower side, be connected with flotation gear on described, described isolation bucket bottom is connected with loach ovum collecting mesh bag, described loach ovum collecting mesh bag bottom is provided with out the ovum mouth, and this goes out the ovum mouth and seals when normality.

When using this device, by the isolation bucket paired close loach is limited in the less scope of activities, improve its fertilization rate, flotation gear can make the isolation bucket float on the surface, the upper end that guarantees the isolation bucket exceeds the water surface, prevent that close loach from running out of in the isolation bucket, the convenient collection of loach ovum collecting mesh bag fertilized egg, the ovum mouth that goes out of its bottom all seals in normality, and fertilized egg is because himself gravity, be in loach ovum collecting mesh bag bottom, just open when getting ovum, fertilized egg directly falls from the exit, collects Fertilized Eggs of Loach very convenient, and can not make ovum injured, improved the survival rate of ovum.

Described loach ovum collecting mesh bag is greater than 300 purpose polythene nets, and this loach ovum collecting mesh bag diminishes from top to the bottom gradually, is funnel-form, and describedly goes out the ovum mouth and hitch by noose.

Can collect the loach ovum greater than 300 purpose polythene nets, up big and down small mesh bag is convenient to collect fertilized egg, is locked by noose when going out ovum mouth normality, opens noose and get final product when getting ovum, and is easy to operate.

Described isolation bucket bottom is connected with the mesh bag support frame, and the inner space that this mesh bag support frame consists of dwindles from top to bottom successively, and this mesh bag support frame is propped up loach ovum collecting mesh bag.

The mesh bag support frame can be propped up loach ovum collecting mesh bag, avoids loach ovum collecting mesh bag to be reduced to together, makes the scope of activities of close loach too narrow.

Described loach ovum collecting mesh bag top is provided with separation net, and this separation net is connected with an isolation bucket lower end or is arranged at mesh bag support frame periphery.

By separation net close loach and loach ovum are kept apart, the loach ovum can fall into loach ovum collecting mesh bag by separation net, prevents close loach because of the loach ovum of eating, and prevents that close loach from running out of from going out the ovum mouth when collecting the loach ovum.

Described flotation gear is the plastic tube of a circle sealing, and this flotation gear is connected with the outer wall of isolation bucket.

By plastic tube the isolation bucket is swum on the water surface, plastic tube is drawn materials conveniently, and cost is lower.

Described isolation bucket is Plastic Drum.

The beneficial effects of the utility model are: close loach is fixed within the specific limits, improved the fertilization rate of close loach, improved the survival rate of fertilized egg, convenient collection fertilized egg.

Embodiment

The utility model is described in further detail below in conjunction with drawings and Examples:

As illustrated in fig. 1 and 2, a kind of loach breeding bucket, comprise all uncovered isolation buckets 1 of upper and lower side, this isolation bucket 1 is Plastic Drum, be connected with the flotation gear 3 that a circle is made by plastic tube on described isolation bucket 1 outer wall, described isolation bucket 1 bottom is connected with by steel bar makes mesh bag support frame 6, the inner space that mesh bag support frame 6 consists of dwindles from top to bottom gradually, be funnel-form, described isolation bucket 1 bottom is connected with loach ovum collecting mesh bag 2, this loach ovum collecting mesh bag 2 is positioned at mesh bag support frame 6 peripheries, and mesh bag support frame 6 is propped up loach ovum collecting mesh bag 2, and this loach ovum collecting mesh bag 2 is greater than 300 purpose polythene nets, this loach ovum collecting mesh bag 2 diminishes from top to the bottom gradually, described loach ovum collecting mesh bag 2 bottoms are provided with out ovum mouth 4, and this goes out ovum mouth 4 places and is provided with noose 5, and this goes out ovum mouth 4 and hitches by noose 5 when normality, when collecting the loach ovum, noose 5 is opened, and loach ovum collecting mesh bag 2 tops are provided with separation net 7, and this separation net 7 is connected with isolation bucket 1 lower end.
