Description

Technical Field

[0001] The utility model relates to the technical field of sandworm breeding, in particular to a double-toothed sandworm mating auxiliary device. Background Art

[0002] As the name suggests, the mating auxiliary device for double-toothed sandworm refers to the equipment and tools for double-toothed sandworm breeding and reproduction. It is commonly used in the sandworm breeding industry. Sandworms belong to the phylum Annelida, class Polychaeta, order Wandering, and family Nereids in taxonomy. There are about 80 species of sandworms in my country, of which double-toothed sandworms are one of the economic breeding species. They often live in coastal mudflats with freshwater inflow, and in the sand and mud from the middle intertidal zone to the subtidal zone. Sandworms have high nutritional value and have therefore been widely used in aquaculture.

[0003] After searching, it was found that a double-toothed sandworm mating device was disclosed in a utility model patent with Chinese patent publication number CN215380810U. The double-toothed sandworm mating device in the utility model patent is designed to place the breeding mother sandworm and the larval egg group separately by designing a placing groove and a collecting groove, and the placing groove and the collecting groove are designed to be a removable structure by using a card block and a card slot, which is convenient for collecting the breeding mother sandworm and the larval egg group of sandworm. However, the double-toothed sandworm mating device only uses the card block and the card slot to limit the placing groove and the collecting groove, and makes them suspended inside the device box. The breeding personnel need to pull the card block to release the limit. The collecting trough needs to be fixed by hands at the same time, which may cause the collecting trough to accidentally fall over after losing its limiting effect, resulting in damage to the larval egg groups on the collecting trough. It is not convenient to collect them by adjusting the placement height of the mother sandworm and the larval egg groups. At the same time, sandworms like to live in a humid muddy environment with a certain temperature and humidity, and the egg-laying environment provided by the double-toothed sandworm mating device is maintained at a constant temperature by heating with a local heat source, which may cause baking stimulation to the mother sandworm and lead to a low egg-laying rate. Therefore, the sandworm placement structure and thermal insulation effect need to be further improved, and thus a double-toothed sandworm mating auxiliary device is proposed. Utility Model Content
