Problems solved by technology

[0004] The present invention aims at the problem that the weight of soft parts of the oyster industry in my country cannot be effectively improved at present, and systematically studies the influence rules and parameters of different developmental periods and seasons of oysters and the seedling cycle on the weight of soft parts of different tidal levels in the intertidal zone. Soft-body weight characteristics of interzone tides, providing a low-carbon approach to increase soft-body weight of oysters

Embodiment 1

[0020] In November 2018, the oysters that need to increase the weight of the soft body were selected from the Jimo Sea District of Qingdao. The selected oysters had a complete shell, a shell height of 6-8cm, an individual weight of 50-100g, and the soft body gonads were not developed.

[0021] The sea area of ​​Huangdao District, Qingdao City was selected as the breeding area. The average annual content of diatoms in the sea area was 100 cells / mL. ) and the average low tide line B (ie, 100cm), the height difference is 280cm, and the average annual water velocity is 0.1-0.3m / s.

[0022] In the subtidal zone of this area, stainless steel is used to build a breeding platform with a weight-lifting soft body. The platform is 4m long and 1m wide, supported by stainless steel, and the bottom end is fixed to the seabed;

[0023] The culture platform set at the average low tide line B was used as the experimental group, and a culture platform at the subtidal zone -50cm position was set...

Embodiment 2

[0026] In November 2018, the oysters that need to increase the weight of the soft body were selected from the Jimo Sea District of Qingdao. The selected oysters had a complete shell, a shell height of 6-8cm, an individual weight of 50-100g, and the soft body gonads were not developed.

[0027] The sea area of ​​Huangdao District, Qingdao City was selected as the breeding area. The annual average content of diatoms in the sea area was 100 cells / mL, and the water quality reached the NY5052-2001 pollution-free food mariculture water standard, and the average high tide line A and the average low tide The height difference of line B is 280cm, and the average annual water velocity is 0.1-0.3m / s.

[0028] In the subtidal zone of this area, stainless steel is used to build a breeding platform with a weight-lifting soft body. The platform is 4m long and 1m wide, supported by stainless steel, and the bottom end is fixed to the seabed; the breeding platform at the average low tide line B ...

Abstract

The invention relates to a production technology of high-end oysters, in particular to a method for increasing the weight of soft parts of oysters. The method comprises the following steps: selecting a low tide zone of an intertidal zone or a subtidal zone and a sea area with the tidal range of more than 250cm as a culture area, putting adult oysters which are used as samples and have complete and healthy shells before marketing into an oyster culture cage, horizontally placing the oyster culture cage on a culture platform of a low tide line of the tidal range, and culturing for 30-120 days to increase the weight of the soft parts of the samples. Compared with the prior art, the method has the advantages of environmental protection, low carbon, short period and high efficiency. In a word, the weight of the soft part of the oyster can be rapidly increased in a low-carbon mode, the quality of the oyster and the economic benefit of the industry are remarkably improved, and the current situation that international high-end oyster products are monopolized is broken through.

Description

technical field [0001] The invention relates to a production technology of high-end oysters, in particular to a method for increasing the weight of the soft parts of oysters. Background technique [0002] Oysters are the world's most important marine aquaculture shellfish, and my country's oyster production ranks first in the world for many years. About 30% of oysters in my country enter the processing or consumption market in the form of soft parts. The weight of the soft parts of oysters directly determines the unit price of the soft parts of oysters, and is also an important standard for oyster processing enterprises to classify products. [0003] At present, oysters are mainly cultivated in the subtidal zone of the open sea. However, due to changes in water temperature in the subtidal zone and changes in bait abundance and reproduction, the soft body weight of oysters often decreases suddenly. Concentrating on low-cost sales before eggs, it is impossible to effectively ...
