Problems solved by technology

[0006] For this reason, what the present invention intends to solve is that the hatching density of the existing frogs is too large, easy to pile up, the hatching conditions are harsh, the management is complicated, the operation and observation are inconvenient, and the hatching rate and early stage cultivation survival rate of tadpoles are reduced, thereby Restricting the technical problems of large-scale production of spinosa, a kind of hatching condition is simple and easy to implement, the environmental conditions such as light are quantified, the water quality is strict, the hatching rate of tadpoles and the survival rate of pre-cultivation are high, and the hatching rate of tadpoles is high. The method for hatching the tadpole seedlings of hatching healthy and strong spiny-chested frog eggs

Embodiment 1

[0032] In this embodiment, the hatching frame for preventing escape of spiny-breasted frog eggs is as follows: figure 1 , figure 2 and image 3 As shown, it includes a frame body and a mesh cloth arranged at the bottom of the frame body; the frame body is surrounded by side frames, and the top of the side frame is provided with a frame perpendicular to the side frame and buckled inward The eaves, the mesh cloth is 10-25 mesh mesh cloth. The frame body is surrounded by the first side frame 31, the second side frame 32, the third side frame 33, and the fourth side frame 34, and the frame eaves are formed by the first frame eaves 51, the second frame eaves 52, the third frame eaves The frame eaves 53 and the fourth frame eaves 54 are surrounded by the first side frame 31 and the second side frame 32, and the third side frame 33 and the fourth side frame 34 are respectively connected to the first side frame 32. The side frame 31 and the second side frame 32 are adjacent and op...

Embodiment 2

[0037] The present embodiment is a hatching method of spinosa spinosa eggs, the method comprising the following steps: hatching environmental conditions; use of a hatching frame; hatching operation; tadpole cultivation after hatching.

[0038] In this embodiment, the hatching frame for preventing escape of frog eggs of Spinosaurus spinosa in Embodiment 1 is used.

[0039] The hatching environmental conditions are: (1) The hatching tank conditions are: select an area of ​​6m 2 1. The cement hatching pool with a pool depth of 60cm is constructed of masonry at the bottom and four walls, painted with cement and mortar, and finally smoothed with cement slurry. The bottom of the pool is required to be smooth and impermeable; At one corner of the bottom, a water level riser is set, and the water inlet is set above the water surface to maintain the water exchange of the whole pool and create a micro-flow environment; (2) The hatching environment is: build a sunshade and rain shelter a...

Abstract

The invention belongs to the field of aquaculture, and particularly relates to a hatching method of quasipaa spinosa frogspawn. The method comprises the following steps of preparation of hatching ambient conditions, use of a hatching frame, hatching operation and cultivation of tadpole out of a membrane, wherein the hatching ambient conditions include hatching pond conditions and hatching environment, and the hatching operation comprises three-layer filtration of hatching water. The hatching ambient conditions, the use of the hatching frame, the hatching operation and the cultivation of the tadpole out of the membrane are optimized, and the illumination intensity of a hatching pond, the dissolved oxygen and pH of water in the hatching pond, the specific form of the used hatching frame, the hatching density, specific operations of the three-layer filtration of the hatching water and the cultivation of the tadpole out of the membrane are further optimized, so that the tadpole hatching density can reach 2000 tadpoles per square meter, and the tadpole hatching rate is increased, so that hatched small tadpoles are strong, and a good foundation is provided for the subsequent tadpole cultivation.

Description

technical field [0001] The invention belongs to the field of aquaculture, and in particular relates to a method for hatching eggs of spinosa spinosa. Background technique [0002] Spinosaurus frog, also known as stone frog, rock chicken, pit frog, stone scale, stone jelly, etc., belongs to the amphibian frog family and is mainly distributed in the mountainous areas of southern my country. More than 85% of its stomach contents are insects harmful to the growth of trees; the body is large and strong, the meat is fresh and tender, rich in nutrition, and its nourishing effect is favored by people. Due to the increasing demand for spiny-breasted frogs and the increasing scarcity of wild resources, the market price of spiny-breasted frogs has also increased. Therefore, artificial breeding of spiny-breasted frogs has significant social, ecological and economic benefits. [0003] The hatchability of Rana spinosa is not only related to the quality of the frog eggs itself, but also c...
