Crayfish breeding nest and combined crayfish breeding device with same

Abstract

The invention discloses a crayfish breeding nest and a combined crayfish breeding device with the same. The crayfish breeding nest comprises a base, a ventilation platform located above the base, a nest frame connected between the base and the ventilation platform, and a nest unit arranged on at least one side of the nest frame, wherein the base, the nest frame and the nest unit are all arranged in an aquaculture water, the ventilation platform is exposed out of the aquaculture water, the nest unit comprises a plurality of nest bodies, the plurality of nest bodies are arranged side by side inthe horizontal direction and the vertical direction, a gap is formed between every two adjacent nest bodies, each nest body comprises a nest chamber, a hole and a channel extending outwards from the nest chamber relative to the nest frame and connected with the hole, and the length of the channels, extending outwards relative to the nest frame, of the nest bodies on the upper sides is less than the length of the channels, extending outwards relative to the nest frame, of the nest bodies on the lower sides. Through the gradient structure design of the breeding nest, crayfishes are convenientlydistributed into each layer of nest bodies, the effective breeding area is increased, and the space utilization rate of the aquaculture water is increased.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a crayfish breeding nest and a combined crayfish breeding device having the same. Background technique [0002] Crayfish are small in size, and the weight of adult shrimp is about 30 to 50 grams. They live in a shallow water environment and like to dig burrows during the breeding season. The burrows are located about 20 cm above the water surface of the pond. Humidity, the hole is generally sealed with a mud cap to reduce water loss. It has the habit of climbing ashore on summer nights or after heavy rains. Moreover, they have a strong sense of territory and are prone to fight with each other, causing breeding losses. [0003] Some of the existing crayfish breeding nests adopt a honeycomb structure, and some adopt a hanging cave structure. The above breeding structures generally have the following defects: 1. There is no gradient on both sides of the breeding nest, which is...

Problems solved by technology

And strong sense of territory, easy to fight with each other, resulting in breeding losses

[0003] Some of the existing crayfish breeding nests adopt a honeycomb structure, and some adopt a hanging cave structure. The above breeding structures generally have the following defects: 1. There is no gradient on both sides of the breeding nest, which is inconvenient for crayfish to climb up and down, and the utilization rate of the upper cave is low. , reducing the effective space utilization rate of aquaculture water

2. There is no platform exposed to the water on the top of the lobster nest, which is not conducive
