Description

Technical Field

[0001] This utility model relates to the field of stone frog hatching technology, specifically to an egg collection board suitable for stone frog reproduction. Background Technology

[0002] The spiny-breasted frog (Rana spinosaurus) is a farmed amphibian species with high economic value, distributed in southern China. It is widely popular in the market for its tender meat and rich nutrition, and its artificial breeding industry has developed rapidly in recent years. The artificial breeding process of the spiny frog includes hatching, tadpole rearing, and growth management, among which the "egg laying and hatching" stage is the key technology affecting the survival rate and economic benefits.

[0003] In their natural habitat, stone frogs tend to choose small, sheltered spaces with gentle water flow, such as rock crevices or densely vegetated areas, for spawning. These environments offer excellent concealment, stable temperature and humidity, and gentle water flow, which are conducive to egg attachment and embryonic development. However, existing artificial breeding environments often fail to provide spawning induction conditions similar to those in nature, leading to insufficient spawning willingness among female frogs or the scattering of eggs at the bottom of the pond, resulting in the following problems:

[0004] 1. Egg masses are scattered and deposited, lacking centralized collection methods;

[0005] 2. Eggs are easily contaminated by impurities, sediment, and decay, which reduces the hatching rate;

[0006] 3. Lack of specialized egg-laying structures suitable for the behavioral habits of stone frogs;

[0007] 4. Artificial intervention to collect eggs after spawning is difficult and can easily damage the eggs.

[0008] Some farmers have attempted to improve and apply the structural principles of egg-collecting frames for insects such as black soldier flies and mealworms. However, due to the significant differences between amphibians and insects in their oviposition behavior, physiological habits, and ecological needs, existing egg-collecting devices are severely lacking in guidance, structural adaptability, and operational stability, failing to effectively improve the egg-laying rate and egg utilization efficiency of stone frogs. Utility Model Content

[0009] The purpose of this invention is to provide an egg-collecting board suitable for the breeding of stone frogs, thus solving the problems mentioned in the background art.

[0010] Technical solution

[0011] To achieve the above objectives, this utility model is implemented through the following technical solution: an egg collection board suitable for the breeding of stone frogs, comprising an egg collection board, wherein the upper surface of the egg collection board is provided with a through-hole mesh structure with a hole diameter not greater than mm, an anchoring component is installed on the outer side of the egg collection board, a foldable handle is provided on the inner side of the egg collection board, and a spacer is provided on the lower surface of the egg collection board.

[0012] Furthermore, the spacer is placed between adjacent egg-collecting plates to adjust and fix the width of the gap between the plates, forming a gap environment suitable for the stone frog to lay eggs. The gap width is preferably set between 8mm and 15mm to accommodate the stone frog's burrowing characteristics.

[0013] Furthermore, the perforated mesh structure: the mesh diameter at the bottom of the egg collection plate is controlled to be no more than 2mm to ensure that water can pass through and prevent the frog eggs from falling into the pool through the mesh.

[0014] Furthermore, the anchoring structure includes anchoring buckles installed before and after the egg-collecting plate to fix the egg-collecting plate in the pond, preventing the egg-collecting plate from shifting due to water flow or frog movement, and ensuring the overall device is stably installed in the aquaculture pond.

[0015] Furthermore, the egg collection board is made of hydrophilic, non-toxic, and environmentally friendly materials, such as bamboo, composite fiberboard, and environmentally friendly plastics, which have anti-hydrolysis and antibacterial properties and are suitable for aquaculture environments.

[0016] This invention provides an egg-collecting board suitable for the breeding of stone frogs. It has the following beneficial effects:

[0017] This egg-collecting board is suitable for the breeding of stone frogs. The entire egg-collecting board can be placed in the water at the bottom of the breeding pond and fixed in the water by inserting buckles. Open the water inlet to create water flow, and cover the water surface with a foam board to create a dark environment. During the breeding season, stone frogs will be attracted by the dark and flowing water and will autonomously burrow into the egg-laying board to lay their eggs. The egg masses will naturally attach to the top foam board and the walls of the egg-collecting board. Eggs that are not attached will be scattered on the egg-collecting board. After egg collection, the entire egg-collecting board can be removed and directly transferred to the hatching pond or hatching device without the need for further transfer or processing.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figure 1-2 As shown, this utility model embodiment provides an egg collection board suitable for the breeding of stone frogs, including an egg collection board 1. The material of the egg collection board 1 is selected from bamboo strips, fiber composite boards, or biodegradable plastics. The egg collection board 1 is suitable for breeding ponds of different shapes and can be assembled into circular, rectangular, or polygonal layouts. The upper surface of the egg collection board 1 is provided with a through-hole mesh structure 3 with a pore size of no more than 2 mm. The rough surface of the egg collection board 1 is formed by sandblasting, etching, or coating, with a surface roughness of Ra 10~50 μm. Multiple small-diameter meshes with a mesh diameter of less than 2 mm are opened on the board surface to facilitate water circulation and aeration, egg attachment, and stable egg laying. An anchoring component 2 is installed on the outer side of the egg collection board 1. The anchoring component 2 is an L-shaped pressure block, an adsorption structure, and The counterweight base can be composed of suction cups, weighted stones, or hook structures to stably fix the entire egg collection device to the bottom or wall of the pool, preventing displacement caused by water flow disturbance or frog activity. The inner side of the egg collection plate 1 is equipped with a foldable handle 4, which adopts a foldable design to fit the plate surface when stored, without hindering frogs from entering or exiting. The surface of the foldable handle 4 has an anti-slip texture, which is convenient for manual gripping and improves the ease of handling the device for overall transfer or cleaning. The lower surface of the egg collection plate 1 is equipped with spacer pads 5, and circular pads with a thickness controlled between 8mm and 15mm are set between the egg collection plates 1 to form narrow slit channels suitable for stone frogs to crawl into. The pads can be connected to the egg collection plate 1 through buckles or slots to achieve modular assembly and disassembly.

[0023] Working principle: The egg collection board 1 is placed vertically in the underwater area of ​​the stone frog breeding pond. After being fixed by the anchoring component 2, it does not move with the water flow.
