Description

Technical Field

[0001] The present invention relates to the technical field of aquaculture workboats, and in particular to a fully automatic and rapid conveying system for fry entering the cabin of an aquaculture workboat. Background Technique

[0002] Aquaculture workboats are a new direction for China's fishery to develop towards the deep sea and are a solution for realizing deep-sea aquaculture. Aquaculture workboats can avoid the influence of bad weather such as typhoons and red tides, and can transfer production according to environmental requirements. They are self-propelled fishing vessels.

[0003] Large yellow croaker is a marine fish with high economic value and delicious taste, and is deeply loved by the broad masses of the people. The large yellow croaker fry must be temporarily raised in the nursery to 5-7 cm before they can be transported to the large offshore cages for release. The fry entering the cabin is an important link in the aquaculture workboat. In order to save transportation costs, the density of fry loaded on the fry transfer ship is relatively large. How to quickly put the fry into the aquaculture water tank under high sea conditions while reducing fry losses has become an urgent problem to be solved. When putting the fry into the aquaculture cabin, attention should be paid to fast actions and balanced placement to avoid oxygen deficiency and resulting losses. The existing fry transfer has the following problems: First, when transferring the fry from the fry transfer ship to the net cage and from the net cage to the aquaculture cabin, the fry will rub against the edges of the transfer ship and the net cage, damaging the fish scales and epidermis of the fry, causing stress and infection, and damaging the fry. Second, when transferring the fry from the net cage to the aquaculture cabin, an outlet is usually set at the bottom of the net cage, which results in a small outlet. When migrating the fry, a large number of fry rush to the outlet and rub against each other, and it is easy to cause stress and damage the fry, increasing the aquaculture cost.

[0004] CN202110358643.3 discloses a fry entering the cabin transfer system and method. The system includes a number of live fish transport ships, a number of fry entering the cabin transfer boxes, and an aquaculture workboat; a number of cranes and a number of aquaculture cabins are arranged on the aquaculture workboat, and the dry fry entering the cabin transfer boxes are suspended on the cranes. The fry entering the cabin transfer system and method of the present invention can smoothly transfer the fry from the live fish transport ship to the aquaculture cabin of the aquaculture workboat, and can greatly reduce the damage of live fish, ensuring the smooth development of aquaculture production. This patent has the problem of a small fish outlet and damage to the fry.

[0005] CN215098141U discloses an improved live fish transport ship, which relates to the technical field of live fish transport ships, including a cabin, wherein a fish storage bin for temporarily storing live fish is provided on the upper part of the cabin, a lifting mechanism for tilting the fish storage bin toward the front is provided on the bottom of the cabin, and the lower surface of the fish storage bin is fixedly connected to the upper surface of the support plate, and a liftable baffle is provided on the fish lowering side of the fish storage bin, and the baffle is used to block the fish outlet side of the fish storage bin, and a plurality of fish separation grooves are provided on the upper surface of the fish storage bin. This patent sets a plurality of fish separation grooves and baffles, which can ensure the smoothness and speed of fish lowering, but a large number of fry will still rub against the edges of the fish separation grooves and baffles, scratching the fish body, causing stress, reducing the survival rate, and increasing the breeding cost.
