Problems solved by technology

However, shellfish eggs only have a thin layer of egg membrane, which is easily decomposed by bacteria in vitro and sinks very easily, so the eggs that have not been ingested decompose in the water and easily pollute the water quality; while the fertilized eggs with activity have been carrying on in the water. The fertilized eggs that have not been ingested will develop into D-shaped larvae after 24 hours. At this time, the larvae have formed a shell, and it is easy to cause damage to the fry when they are accidentally eaten by fry. Therefore, directly feed shellfish eggs or fertilized eggs as fry. There are still great limitations in bait
[0003] In a word, the prior art lacks an open bait suitable for the large-scale cultivation of smaller fish fry with clefts.

Embodiment 1

[0042] (1) Selection of parent shellfish: Hepu pearl oyster shellfish is a two-year-old shellfish with a shell length of about 6cm that was bred by the research group in Xincungang, Lingshui County, Hainan Province. The surface attachments were removed with a knife and cleaned with a brush. Put it in a cool place and dry it in the shade for 3 hours. When the double shell of Hepu Pinctada is opened, observe the gonad development of Hepu Pinctada under light conditions, and select 30 female shells and 10 male shells with better gonad development.

[0043] (2) Obtain sperm and eggs: Dissect 30 selected female shellfish and 10 male shellfish respectively, take their testis and ovaries, wrap the ovaries with 150-mesh silk mesh and squeeze them to a volume of 10L and filter them with 4L In the barrel of seawater, the testis is wrapped and extruded into a 500mL plastic cup filled with 400mL filtered seawater with a 150-mesh sieve.

[0044] (3) Artificial insemination: The seawater wh...

Abstract

The invention discloses a fish fry starter bait and an obtaining method thereof. The fish fry starter bait is composed of polar cells of animals and plants separated in an embryonic development process of pinctada fucata oosperms. The fish fry starter bait provided by the invention is more suitable for large-scale cultivation of fish fries with relatively small oral fissures.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to the field of open bait for fry cultivation. Background technique [0002] Since 1960, artificial breeding in aquaculture has begun to use the rotifers of the genus Brachionus as the opening bait for fry, and it is still widely used in the world today. The reason why rotifers are used as bait in the breeding of larvae and juveniles is mainly because they can be cultured at high density under artificial conditions, their size is suitable for the feeding caliber of most larvae and juveniles, and their swimming speed is slow. It is easy to be caught by larvae and juvenile fish, and has become an indispensable biological bait in the cultivation of fish fry. However, for some species of newly hatched larvae, such as the newly hatched larvae of grouper and bluefish, their mouth openings are relatively small, and the open bait can only eat bait with a particle size of less than 60 μm, while t...
