Embodiment 2

[0033] Embodiment 2: a kind of method for hatching the excellent fertilized egg of the star flounder, it is characterized in that: comprise the steps:

[0034] S1: Inject natural seawater into the hatching device to fill the container;

[0035] S2: Adjust the water temperature of the natural seawater to between 10 and 15°C;

[0036] S3: Continuous heating of natural seawater;

[0037] S4: continuous inflation of natural seawater;

[0038] S5: Maintain the continuous inflation state, and at the same time adjust the flow of water in the upper inlet pipe to the daily water exchange volume in the bucket within the range of 20-30%;

Abstract

The invention belongs to the field of incubation of spotted halibuts and aims at providing an incubation device and method for good fertilized eggs of spotted halibuts. The device is characterized bycomprising an incubation pond, the incubation pond comprises a cylindrical barrel and a conical barrel connected with the end face of the cylindrical barrel, the cylindrical barrel is matched with a water inlet pipe and a water filter, and a sewage discharging pipe is connected to the end, away from the cylindrical barrel, of the conical barrel. The device is convenient and quick to operate, the harm to roes is small, and the incubation survival rate is increased in comparison with common operation.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a hatching device and a method for fertilized eggs of the star flounder. Background technique [0002] Star flounder is mainly distributed in my country's Yellow Sea, Bohai Sea, and the northern coasts of South Korea and Japan. Over the years, due to overfishing and environmental changes, its natural resources have declined, and its catches have decreased year by year. Natural resources are becoming increasingly exhausted and endangered. The suitable growth water temperature is 15℃~23℃, and the suitable salinity range is 23~31. [0003] The process of embryonic development of the eggs of Pleurotus flounder is as follows: when the water temperature is (11±0.5)°C, the fertilized eggs hatch out after 153 hours, and the hatched larvae feed through the opening for 6 days when the water temperature is (15±0.5)°C , 50d to complete metamorphosis into juvenile fish. [0004] The egg...
