Embodiment Construction

[0033] Please check figure 1 , figure 2 and image 3 The invention discloses an ovum picker for collecting oocysts of dongfeng snails, which includes a plastic plate on which a film is pasted. The ovipositors of the present embodiment are divided into three types, and are respectively the first ovipositor, the second ovipositor and the third ovipositor.

[0034] The first egg picker is plate-shaped and includes a plastic plate 10 , and a film 20 is pasted on the front of the plastic plate 10 .

[0035] The second ovipositor is in the shape of a "herringbone", and the second ovipositor includes two plastic plates 10', and the tops of the two plastic plates are affixed together so that the two plastic plates form a "herringbone"-shaped structure; Films 20' are pasted on the front and back sides of the plastic board 10'. A slot is arranged above the one plastic board, and an insertion part is protruded from the other plastic board, and the insertion part is inserted into the...

Abstract

The invention discloses a Babylonia lutosa egg capsule collection method and an egg collector. The Babylonia lutosa egg capsule collection method includes: step10 parent shellfishes are placed into a pool, sands are paved at the bottom of the pool, and baits are thrown into the pool to feed the parent shellfishes; step 20 the egg collector is placed in the pool, wherein the egg collector comprises a plastic board, and a film is attached to the plastic board; step 30 the parent shellfishes lay eggs, and the laid Babylonia lutosa egg capsules are attached to the film; and step 40 the egg collector is taken out, and the film attached with the egg capsules is torn off from the plastic board and placed into an incubator. The Babylonia lutosa egg capsule collection method has the advantages that the plastic board is in accordance with characteristics of the Babylonia lutosa egg capsules and is simple to produce and cheap and durable in materials; the film is adopted so that the method is simple and low in cost; and egg taking is fast and the taken eggs are integral.

Description

technical field [0001] The invention relates to a method for collecting Nidongfeng snail oocysts and an ovum picker. Background technique [0002] The collection of oocysts is the first step in the artificial breeding of Nidongfeng snails. The broilers are temporarily raised in the indoor cement pool. The bottom of the pool is covered with a sand layer of 8-10 cm, the water depth is 70 cm, and the running water is inflated. There is 90% shading on the top of the pool. High-efficiency sunshade nets to avoid direct sunlight. After a period of nutritionally intensive cultivation, they begin to mate and lay eggs naturally. Most of the eggs are laid at night, and a few are during the day. Female broodstock will choose a smooth surface to lay eggs, so the oocysts produced are mostly attached to the pool wall and about 20cm away from the bottom of the pool. Now the general nursery field uses a plastic water pipe with a diameter of 11cm and a length of 15-20cm as the egg collector. ...
