Embodiment 1

[0023] Such as Figure 1-7 Shown: the fish and turtle polyculture pond using the mesh hanging device, including the polyculture pond 2, the mesh hanging device is arranged at intervals above the polyculture pond 2, and the mesh hanging device is arranged on both sides of the polyculture pond 2 The fixed piles 1 are connected with ropes 3 between the fixed piles 1, and the floating nets 4 are connected at intervals on the ropes 3, and the ropes 3 are connected to the floating nets 4 at intervals on one side or connected to the floating nets 4 at intervals on both sides of the ropes 3. The above scheme adopts the net The method of sheet hanging effectively solves the problem that the cultured soft-shelled turtle lives at the bottom of the water for a long time and repeatedly moves a lot from the bottom to the water surface when breathing, and avoids the internal consumption of the cultured soft-shelled turtle that is affected by the water pressure and the amount of exercise durin...

Embodiment 2

[0028] Breeding experiments were carried out in Dinghai District, Zhoushan, Zhejiang:

[0029] 1) Pond: Choose a flat-bottomed less-silted pond with a water depth of 2.5 meters, surrounded by cement slope protection, and the slope is vertical; above the pond, a mesh hanging device is used, and a feed table is set up, and the pond is installed symmetrically for high temperature and low oxygen. Water pump for convection and circulation of oxygen in the pool;

[0030] 2) Stocking seedlings: stocking silver carp and silver carp with 80-120 tails per mu before and after the Spring Festival; stocking soft-shelled turtle species at the end of May, the water temperature must be above 25°C, and stocking Japanese soft-shelled turtle species with a size of 0.3-0.5 kg each. 400-500 per mu;

[0031] 3) Automatically adjust the water quality: use the ecological chain to automatically adjust the water quality. In May, a number of 2-meter-wide water grass strips are moved longitudinally into...

Abstract

The invention provides a fish and turtle polyculture pond using mesh sheet hanging devices, and belongs to the technical field of aquaculture. The fish and turtle polyculture pond comprises a polyculture pond, the mesh sheet hanging devices are arranged above the polyculture pond, every the mesh sheet hanging device comprises fixed piles arranged at two sides of the polyculture pond, a rope is connected between the fixed piles, floating nets are connected to every rope at intervals, one sides of the ropes are connected with the floating nets at intervals, or two sides of the ropes are correspondingly connected with the floating nets at intervals. The fish and turtle polyculture pond solves the problems of poor quality and slow growth of turtles, low culture space utilization rate and easypollution of a culture net in fish and turtle polyculture, and avoids the in vivo consumption caused by the hydraulic pressure influences on cultured turtles staying underground for a long term and the exercise amount during breathing; and the floating nets are in a suspended state when no turtles exist on the surfaces of the floating nets, occupy a small space in water, have a strong light transmission property, do not affect the photosynthesis of water plants in the culture water, and maintain the ecological balance in the polyculture pond.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a fish and turtle polyculture pond using a mesh hanging device. Background technique [0002] Over the past few years, the construction of commercial fish bases has been carried out in various places, and the transformation of fish ponds in large-scale fish farming bases has been continuously promoted. The ponds have been changed from small to large, and from shallow to deep. Since this kind of fishpond has cement pouring for slope protection, there is no need to build additional anti-escape facilities for stocking Chinese soft-shelled turtles. Therefore, more and more methods of polyculture of fish and soft-shelled turtles are adopted. However, practice over the past few years has shown that the growth rate of polyculture soft-shelled turtles is generally slow, and the number of polyculture is not ideal. The reason is that in the past, the density, bait and stoc...
