Embodiment Construction

[0016] A two-step method for cultivating large-scale seedlings of hard shell clams, comprising the following steps:

[0017] (1) Cultivation of spat in cement ponds:

[0018] Spatial shells with a shell length of 800-1000 μm are weighed at 0.1-0.2 kg / m 2 (Example 0.1kg / m 2 、0.2kg / m 2 ) directly into the cement cultivation pool, and continuously increase oxygen, the water depth of the cement cultivation pool is 0.3 ~ 0.5m (for example, 0.3m, 0.4m, 0.5m), and the area of ​​the cement pool is 30 ~ 100m 2 (Example 30m 2 、70m 2 、100m 2 ), using the single-celled algae as the bait (it can be the single-celled algae fertilized by the mixed culture of the white shrimp and the portunus or the single-celled algae cultured by the three poles); every 6 to 8 days, the pond is poured once, and the water is filtered through a 200-mesh silk bag ; When juvenile shells reach 4mm in length, go out of the pool and carry out large-scale seed cultivation;

[0019] (2) Cultivation of large-sc...

Abstract

The invention discloses a two-step method for breeding Mercenaria mercenaries. The method comprises the steps of breeding young shellfish in cement pit, breeding seedlings with large size and so on. The invention overcomes the defects of requirements of multiple staged cares in the past young shellfish breeding. The invention has the advantages of few production steps, simple operation, and few seedlings damage.

Description

Technical field: [0001] The invention relates to a method for cultivating hard shell clams. Background technique: [0002] The existing large-scale seed cultivation of hard shell clams needs to be cultivated in multiple stages, and there are many production links. The operation is cumbersome and the seedling injury rate is high. Invention content: [0003] The object of the present invention is to provide a two-step method for cultivating large-scale seedlings of hard clams that are easy to operate and hard to injure. [0004] Technical solution of the present invention is: [0005] A two-step method for cultivating large-scale seedlings of hard shell clams is characterized in that it comprises the following steps: [0006] (1) Cultivation of spat in cement ponds: [0007] Spatial shells with a shell length of 800-1000 μm are weighed at 0.1-0.2 kg / m 2 The density of the cement is directly put into the cement cultivation pool, and the oxygen is continuously increased. ...
