Problems solved by technology

[0004] Because oysters have the living habit of clustering and fixation, the shell shape is irregular, which causes competition for food and affects the growth rate
The traditional breeding methods mostly use bulky anchoring substrates, on which the juvenile shells grow, and the handling of the anchoring substrates requires a lot of labor.
Because oysters are firmly fixed, harvesting is more troublesome, and oysters that are fixed together increase the difficulty in processing and eating

Embodiment Construction

[0014] The tidal flat and shallow sea oyster monomer culture method of the present invention comprises the following steps:

[0015] Artificial cultivation of individual oyster fry, its cultivation method is a traditional cultivation method, and the specific methods are as follows:

[0016] 1. After the broilers are taken back, wash them clean, pick healthy individuals and put them into 1m×0.8m×0.4m baskets, 150 per basket, and suspend them in the nursery pond with floating balls for temporary cultivation. After entering the pond, the water temperature of broilers is kept stable for three days. After that, the temperature is increased by 1°C, 15°C, and 19°C each day for 2-3 days. When the water temperature reaches 22°C, the constant temperature is cultivated. Pour the pond once a day in the morning and evening, and feed Monocellular algae, spirulina powder, egg yolk.

[0017] 2. Oyster gonads mature, artificial insemination is performed, and triploids are induced by drugs.

Abstract

A method for raising the monomeric oyster in the shoal and shallow sea of northern sea region includes such steps as artificially culturing the larvae of oyster, sticking the larva onto shell, and throwing the shells into the seawater with 0.2-2.5m depth on the ebb.

Description

technical field [0001] The invention relates to a method for cultivating seafood, in particular to a method for cultivating single oysters in tidal flats and shallow seas in the northern sea area. Background technique [0002] There are many ways to cultivate oysters along the coast, which can be divided into three types according to the cultivation methods. One is the ground sowing method, such as sowing stones, tiles and other items at the bottom; The third is the hanging culture method, including grid-type hanging culture, raft-type hanging culture, long-line hanging culture and so on. [0003] The traditional tidal flat sowing is aimed at the intertidal zone, and the seedling picker doubles as a grower, and the fixed oysters grow in situ on the seedling picker until they are harvested. This traditional culture method is difficult to control the culture density artificially, and the culture yield is low and unstable. The culture area of ​​tidal flat sowing method is limi...
