AI Technical Summary

Problems solved by technology

Traditional oyster culture uses stone and bamboo as seedling substrates, and there are many restrictive factors for seedling attachment and cultivation. The breeding area is limited to the intertidal zone, and the oysters have a short feeding time, slow growth, small individuals, low yield, and complicated operations. develop slowly
With the reform of foreign research on oyster culture technology, some areas began to carry out the test of hanging shell string hanging culture in the 1970s, but because some key technical problems such as seedling picking and culture methods have not been well resolved, the economy The benefit is not obvious, and it is still in the small-scale experimental stage for a long time

Embodiment 1

[0017] This embodiment provides a method for cultivating pleated oysters, which includes the following steps.

[0018] Step 1. Selection of breeding area: The water depth at high tide and low tide is 10m, the flow velocity is 50-55cm / s; the bottom is silt or sandy mud, the transparency is more than 50cm, and there is no eddy current or counter-impact current.

[0019] Step 2. Selection of nursery grounds: Select the junction of the middle and low tide areas of the Inner Bay with broccoli, where the flow is slow, the terrain is flat, and sandy and muddy tidal flats.

[0020] Step 3. Set up the seedling picking frame: use moso bamboo or wooden strips as frame bars, and set up a shelf with a width of 1.2-1.5m and a height of 40-45cm from the bottom surface.

[0021] Step 4. Set up the breeding platform: the spacing between the columns is 1.5-1.8m, and the height is 1.3-1.5m from the bottom surface.

[0022] Step 5. Hang the oyster skewers downwind, with a distance of 15cm.

Abstract

The invention provides an aquaculture method of ostrea plicatula. The method comprises the following steps: 1. selecting an aquaculture area according to the conditions of 5-15m water depth during low tide, 40-60cm / s water speed, substrate of sediment or sand, over 50cm transparency, no eddy and no reverse bump flow; 2. selecting a seedling collection ground which locates in the border region between middle and low tidal regions of inner bar with parent oysters and is the sandy mud flat of slower flow rate and flat terrain; 3. arranging a seedling collection support through taking moso bamboo or batten as support bar and putting up a shelf of 1-1.5m wide and 40-50cm away from the bottom; 4. arranging a cultivation stand of 1.5-2m space among shelf pillars and 1-1.5m away from the bottom; 5. horizontally hanging ostrea strings in the direction of following wind with the string spacing of 15-20cm. Through horizontally hanging ostrea strings which makes water resistance small and keeps water flowing, the method avoids bottom mud rising, the asphyxiated death of ostrea strings in mud as well as the dropping and twining of ostrea strings. The aquaculture method of ostrea plicatula is suitable to be applied in shallow aquaculture.

Description

technical field [0001] The invention relates to the technical field of cultivation, in particular to a method for cultivating pleated oysters. Background technique [0002] Pleated oysters, common names: oyster, oyster, white oyster, sea oyster, oyster yellow, oyster. Oyster is an important marine cultured species. Pleated oyster is named for its more folds in shape, and its shell is small, generally 3 to 6 cm long. The body shape is varied, mostly elongated or triangular. The shell is thin and crisp. The right shell is as flat as a cover, with several layers of concentric ring-shaped scales on the shell surface, without radial ribs. The right shell is very concave and cap-shaped, with thick radial ribs and few layers of scales. The surface of the shell is mostly light yellow, mixed with purple brown or black stripes, and the inner surface of the shell is white. Every 100 grams of meat contains 11.3g of protein, 2.3g of fat, rich in vitamins, trace elements zinc, ash an...
