Embodiment 1

[0020] Embodiment 1, a method for two-point inlet and two-point drainage of a rectangular sea cucumber culture pond

[0021] like figure 1 Shown: In the rectangular sea cucumber culture pond, there are two water inlets on the short side wall of one side: water inlet 1 and water inlet 2, and two water outlets on the opposite side: water outlet 3 and water outlet 4, wherein, all The water inlet 1 and the water inlet 2 are symmetrically arranged with the water outlet 3 and the water outlet 4, the water inlet and the water inlet of the water inlet 1 and the water inlet 2 are controlled by the gate 5 and the gate 6 respectively, and the water discharge The drainage and displacement of mouth 3 and outlet 4 are controlled by gate 7 and gate 8 respectively, and the width of gate 5, gate 6, gate 7, and gate 8 is designed to be 8% of the maximum capacity of the pond with the hourly intake and discharge.

[0022] The rectangular japonicus culture pond is 350m long, 100m wide and 150cm d...

Embodiment 2

[0030] Embodiment 2, a method for four-point water intake and four-point drainage in a rectangular sea cucumber culture pond

[0031] like figure 2 As shown: there are 4 water inlets on the short side wall of the rectangular sea cucumber growing pool: water inlet 9, water inlet 10, water inlet 11 and water inlet 12, and 4 water outlets are symmetrically arranged on the opposite wall . The water intake and water intake volume of the four water inlets are respectively controlled by four gates. The gate of the described discharge port is also designed symmetrically with the water inlet gate one by one, and the gate is designed for 10% of the maximum capacity of the pond with the per hour advance and discharge.

[0032] The rectangular japonicus culture pond is 400m long, 120m wide and 200cm deep.

[0033] The central points of the water inlet 9, the water inlet 10, the water inlet 11, and the water inlet 12 are on the same horizontal plane of the short side pool wall of the w...

Abstract

The invention provides a multi-point water inflowing and draining method for a rectangular cultivation pond of stichopus japonicus. The multi-point water inflowing and draining method comprises setting 2-4 water inlets on the short pond walls of the rectangular cultivation pond of the stichopus japonicus, wherein correspondingly, 2-4 water outlets are arranged on opposite pond walls of the short pond walls; the water inlets and the water outlets are symmetrically arranged one by one; inflow and the amout of inflow of the water inlets are controlled by a water inlet gate; drainage and the amount of drainage of the water outlets are controlled by a water outlet gate. The multi-point water inflowing and draining method provided by the invention can effectively reduce the volume of a dead water region inside the pond,can reduce the occurrence of a short-stream phenomenon, and can improve the water quality, the survival rate and the growth speed of the cultivated stichopus japonicus.

Description

technical field [0001] The invention relates to a multi-point water intake and multi-point drainage method for a rectangular sea cucumber culture pond, which belongs to the technical field of sea cucumber culture ponds. Background technique [0002] Sea cucumber is a marine animal with medicinal functions. With the continuous increase in market sales, sea cucumber pond aquaculture has developed rapidly in recent years. Most of the traditional japonicus culture ponds come from the old prawn culture ponds after transformation, and still follow the long-axis direction of water intake and drainage in the central part of one side of the pond and single-point drainage in the central part of the other side, without consideration Breeding habits of non-swimming animals. In recent years, the inlet and outlet of sea cucumber culture ponds have been improved to a single point inlet and outlet along the diagonal direction of the pond, in order to prolong the residence time of the inlet...
