Embodiment 1

[0024] Such as Figure 1-5 Shown, a kind of snail class increases culture reef, comprises culture reef body 21, and culture reef body 21 comprises frame 5, and frame 5 lower surface is vertically arranged with receiving rod 14, and the lower end of receiving rod 14 vertically connects bottom plate 13, and frame 5 surface is provided with Hanging bar 8 is arranged, and the draw-in groove 16 that depth is not uniform is evenly distributed on the hanging bar 8, and bottom plate 13 surfaces are provided with storage net groove 10, and storage net tank 10 built-in anti-escape net 11, and anti-escape net 11 upper end is equipped with hook 9. By setting hanging strips on the surface of the frame, the hanging strips are evenly distributed with card slots, the surface of the bottom plate is provided with storage nets, the storage nets are built with anti-escape nets, and hooks are installed on the top of the anti-escape nets, the operator can put the anti-escape nets Pull it out from t...

Embodiment 2

[0031] Such as Figure 6-7 Shown, a kind of snail class increases culture reef, is the optimized scheme of embodiment 1, and the crossing place of anti-escape net 11 net ropes is provided with water filter ring 12, and water filter ring 12 comprises the lower water filter ring 121 that is connected with net rope , the top of the lower water filter ring 121 is equipped with a water blocking bar 123 inclined outwards, the top of the water blocking bar 123 is provided with an upper water filter ring 122, and the diameter ratio of the 11 meshes of the anti-escape net and the 6 meshes of the breeding net is 0.5: 1. Set the diameter ratio of the mesh of the escape net to the mesh of the breeding net to 0.5:1. It can avoid the overflow of snails and the capture of natural enemies. The water filter ring is set at the intersection of the anti-escape net rope, which can reduce the impact of water flow on the aquaculture reef, and can also purify the aquaculture water. The lower water f...

Embodiment 3

[0034] Experiment: Carry out the snail breeding test. The test snails are selected from the Baisha Vegetable Market in Jiangbei District. The selected snails are in good health, the shell is complete, and the initial weight is 2.5g±0.05g. The test is divided into two groups , each group is respectively established 3 parallel groups, and the test group adopts a kind of snails of the present invention to increase culture reef, and the control group is an aquaculture center in Zhejiang, and the density of each group of snails in the initial stage of the test is 30 / m 2 , the test period is 45 days, and the control water temperature, pH, and relative density of aquaculture water in the control group are basically the same as those in the test group.

[0035] The test records the average daily weight gain and survival rate of the snails, and the body weight of the snails is measured by an electronic balance (HENGPING MP1100B, accuracy 0.001g).

Abstract

The invention provides a culture and proliferation reef for snails, belonging to the technical field of culturing of the snails. The culture and proliferation reef comprises culture reef bodies, wherein each culture reef body comprises a frame; the lower surface of each frame is vertically provided with bearing rods; the lower ends of the bearing rods are vertically connected with a base plate; the surface of each frame is provided with hanging strips; clamping grooves with different depths are uniformly distributed on each hanging strip; the surface of each base plate is provided with a net storage groove; an anti-escape net is internally arranged in each net storage groove; and the upper end of each anti-escape net is provided with hanging hooks. The culture and proliferation reef provided by the invention has the following advantages: through uniform distribution of the clamping grooves with different depths on each hanging strip, each anti-escape net can be adjusted in the overalldegree of tightness by hanging in the clamping grooves with different depths through the hanging hooks, so the alternating speed of the quality of water located at the interiors and exteriors of the culture reef bodies is changed; the balance of water and salt in each culture reef body is promoted; the snails adapt to the nature to grow; and the culturing survival rate of the snails is improved.

Description

technical field [0001] The invention belongs to the technical field of snail culture, and in particular relates to a snail culture reef. Background technique [0002] The intertidal zone along the southeast coast of my country mainly has three types of bottoms: reef, mud and sand. The intertidal zone along the coast of the mainland is dominated by muddy bottom, followed by reef and sandy bottom. The length of the shoreline in the middle zone is more than 60%, and the area accounts for more than 50%. There are dotted islands and reefs along the coast of Zhejiang and Fujian. For example, there are 13,395 islands in the Zhoushan Islands, and more than 3,500 longitudinal islands and reefs. The intertidal zone of the reef bottom is the main body. [0003] Snails are delicious, with high protein content and particularly good nutritional value. Due to excessive harvesting and increased marine pollution in recent years, snail resources have not been effectively protected, and snai...
