Problems solved by technology

[0002] At present, the breeding of cephalopods has started in China. Cephalopods such as large benthic squid are favored by farmers due to their fast growth and short breeding cycle; however, due to their benthic characteristics, benthic squid larvae sink directly into the hatching tank after hatching bottom life, often mixed with the bottom sundries during hatching. On the one hand, it will take a lot of labor to separate the larvae after hatching and move them into clean seawater to continue to grow seedlings; The outbreak of larval diseases has greatly reduced the survival rate of larvae cultivation. This research invented a fully automatic hatching device that can automatically separate and transfer larvae from egg skin and other debris when larvae hatch, simplifying the hatching operation of benthic squid larvae , and increase the survival rate of its follow-up cultivation

Embodiment 1

[0030] like Figure 1~5 Shown, a kind of fully automatic larval hatching device suitable for benthic squid, comprising:

[0031] Incubation tank 1, used to place the fertilized egg incubator and assist squid hatching;

[0032] The fertilized egg incubator 4 is used for the hatching of squid fertilized eggs and the separation of sundries such as egg skins after hatching;

[0033] Spiral air intake pipe 5 is used for air intake to promote the hatching of squid fertilized eggs;

[0034] The temperature sensor 13 is used for real-time detection of the culture water temperature to ensure the survival rate of squid fertilized egg hatching;

[0035] The water quality purification device 14 is used for purifying the water body in the hatch tank to ensure the cleanliness of the water body.

[0036] The hatching tank 1 is connected to the fertilized egg incubator 4 through the suspension ring 2, a temperature sensor 13 is arranged between the hatching tank 1 and the fertilized egg ha...

Embodiment 2

[0047] When a kind of automatic larval hatching device suitable for benthic squid of the present invention is actually used: the hatching tank 1 has an inner space, and the fertilized egg incubator 4 is arranged in the inner space of the hatching tank 1, and the seedling outlet is arranged at 4 on the fertilized egg incubator. The fertilized egg incubator 4 is used to incubate several fertilized eggs in the hatching tank 1, and after the several fertilized eggs are hatched, several aquatic organism seedlings leave the fertilized egg incubator 4 through the seedling exit, and several egg skins or The remaining egg skins are left in the fertilized egg incubator so that the egg skins can be taken out from the fertilized egg incubator. The temperature sensor 13 in the hatching tank 1 can monitor the water temperature of the cultured water in real time. When the cultured water temperature is low, the water quality can be controlled. The high-temperature heating wire 147 and the hig...

Abstract

The invention discloses a full-automatic larva incubating device and method suitable for benthoic squid, and belongs to the technical field of aquaculture; and the full-automatic larva incubating device comprises an incubation tank, a fertilized egg incubator, a spiral air inlet pipe, a temperature sensor and a water purification device. The incubation tank is used for placing the fertilized egg incubator and assisting squid incubation; the fertilized egg incubator is used for incubating squid fertilized eggs and separating egg skins and other sundries after incubating; the spiral air inlet pipe is used for air introduction to promote the incubating of the squid fertilized eggs; the temperature sensor is used for detecting the temperature of breeding water in real time and ensuring the incubating rate of the squid fertilized eggs; and the water purification device is used for purifying the water in the incubation tank and ensuring the cleanliness of the water body. According to the device, water purification can be carried out during the culture, the larva incubation of the benthoic squid is simplified and promoted, the sundries such as the egg skins can be automatically separatedand discharged, and the follow-up cultivation survival rate of the benthoic squid is improved.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a fully automatic larval hatching device and method suitable for benthic cuttlefish.
