4results about How to "Improve hatching efficiency" patented technology

The utility model belongs to the technical field of cuttlefish hatching devices, and particularly relates to a sepiella maindroni seaborne hatching device which comprises a net cage incubator, the net cage incubator is composed of a frame and a net bag, an inverted-L-shaped connecting base is fixedly installed at the top of the net cage incubator, and an electric push rod is fixedly installed on one face of the connecting base. A hollow fixed cylinder is fixedly mounted on one side of the mesh cage incubator, and liquid is stored in the fixed cylinder; when the sepiella maindroni fertilized eggs are hatched, the sepiella maindroni fertilized eggs are quickly sprayed to the mesh cage incubator through the through holes in the fixing frame, so that the fish schools are driven, the sepiella maindroni fertilized eggs are prevented from being ingested by the peripheral fish schools, normal hatching of the sepiella maindroni fertilized eggs is guaranteed, and hatching efficiency is improved.

This utility model discloses a ladybug hatching device, belonging to the field of hatching devices. It includes a hatching base and a hatching cover inserted at the top of the hatching base. The hatching cover contains hatching components for hatching ladybug eggs. Each hatching component includes multiple egg-hatching trays (I), each with an egg-hatching tray (II) above it. Each egg-hatching tray (I) has a sliding plate at its bottom, and broad bean seedlings are cultivated inside. Each egg-hatching tray (II) contains a flat substrate bag. The front surface of the hatching cover has multiple mounting openings adapted to the sliding plate and egg-hatching trays (II). This utility model, by using multiple egg-hatching trays (I and II) to hatch ladybug eggs, can increase the hatching volume. Furthermore, both egg-hatching trays (I and II) can be pulled out, facilitating the quick removal of a certain number of eggs and newly hatched larvae by workers, saving time in picking out newly hatched larvae, and thus improving the hatching efficiency of ladybug eggs.

The present application relates to the hatching field of Procambarus clarkii, and discloses a multi-layer modular Procambarus clarkii egg in-vitro hatching and breeding method and device, which comprises a main frame structure and uniformly arranged hatching components, the hatching components are uniformly arranged in the main frame structure, the main frame structure comprises a fixing frame, a top plate and a bottom plate are respectively fixedly installed on the fixing frame in an up-down manner, the hatching components are supported on the bottom plate, a water pipe is horizontally arranged below the top plate, a faucet corresponding to the hatching components is arranged on the water pipe, and a drain pipe penetrates through the tail part of the hatching component. The multi-layer modular arrangement mode effectively improves the space utilization, is suitable for factory batch hatching production, and can effectively improve the hatching efficiency of Procambarus clarkii eggs and the egg fry quality.

The utility model discloses a triplophysa triplophysa movable barrel type special hatching device, which relates to the technical field of hatching devices and comprises a movable base and a constant-temperature water bath barrel arranged on the top surface of the movable base. An electric heating rod for heating and controlling the water temperature in the constant-temperature water bath barrel is arranged in the constant-temperature water bath barrel; the fixing frame is arranged at the top in the constant-temperature water bath barrel; the incubation bottle is located in the constant-temperature water bath barrel and installed on the fixing frame; the bottle opening of the incubation bottle faces downwards and is inverted, and the bottle bottom is open; the inner cavity of the hatching bottle is a triplophysa triplophysa fertilized egg hatching cavity; the air stone is positioned at the lower part in the hatching bottle; and the air supply source is communicated with the air stone through an air pipe so as to supply air and increase oxygen. The incubator is convenient to move, accurate in temperature control and high in incubation efficiency, and has the advantages of simplicity, easiness in manufacturing and low cost.
