Embodiment Construction

[0025] The sea cucumber pond culture method of the estuary area of ​​the present invention,

[0026] (1) Protect the inner dam slope of the pond, and lay non-woven fabrics on the inner dam slope. The specific method of laying non-woven fabrics is: first, dig a ditch horizontally on the upper side of the inner dam slope. Both depth and width are 1

[0027] About 5 cm, press the upper side of the non-woven fabric upside down in the trench excavated at the upper side of the dam slope, and fill back the excavated soil, then turn the non-woven fabric down and spread it on the dam slope, and then place it on the dam slope. Several evenly distributed weights are pressed on the non-woven fabric, and the heavy objects can be stones to prevent the non-woven fabric from spreading unevenly.

[0028] (2) In spring and autumn, control the water level in the pool to 1.5 meters or 2 meters or 2.5 meters or 3 meters, that is, it can be controlled between 1.5 meters and 3 meters.

Abstract

A method for culturing the spiny sea cucumber in the estuarine region features that the inner slope of its dam is covered by non-woven cloth, the water depth in the pond in controlled to be 1.5-3 m in the spring and autumn, or 2.5-3 m in the summer, and the O2 is filled in the water via the hole on ice layer in the winter, while the surficial fresh water is exchanged by seawater.

Description

technical field [0001] The invention relates to a method for cultivating sea cucumbers, in particular to a method for cultivating sea cucumbers in ponds in the estuary area. Background technique [0002] Apostichopus is the collective name of Echinodermata, and there are more than 900 species of Apostichopus, all of which live in the ocean.
