Problems solved by technology

[0004] In addition, in recent years, the Procambarus clarkii industry has developed rapidly and has made some contributions to my country's economy, but its basic research is relatively backward and weak
The main reason is that it cannot breed smoothly in an indoor soilless breeding environment, it is difficult to carry out multi-generation breeding for a long time, and the survival rate of the small number of offspring bred is also very low, which leads to the inability to continue relevant research, especially Experimental research that requires multi-generation follow-up observation can only be cultivated with the help of outdoor earthen ponds or rice fields, which is not conducive to experimental observation and data collection

Embodiment 1

[0045] The cultivation method of indoor small water body soilless Procambarus clarkii provided by the invention adopts the following steps:

[0046] (1) Choose a container or a room or a temperature-controlled greenhouse with an area of ​​18m 2 , the indoor temperature is controlled between 22-26°C;

[0047] (2) Multi-layer three-dimensional box racks are placed indoors, and several breeding water tanks are placed on each layer of breeding box racks, and the area of ​​the water tanks is 0.5m 2 Left and right, with a height of 25cm. Each water tank is independent and can share a water inlet system or a separate water inlet system. The lowest water level is determined by the position of the water outlet, and the height of the water outlet is 3cm high;

[0048] (3) The water level of each water tank is controlled at 8cm and kept stable, the pH value of the water in the water tank is controlled between 6.8-7.2, and the dissolved oxygen is controlled above 5mg / L;

[0049] (4) Eac...

Embodiment 2

[0057] The cultivation method of indoor small water body soilless Procambarus clarkii provided by the invention adopts the following steps:

[0058] (1) Choose a container or a room or a temperature-controlled greenhouse with an area of ​​30m 2 , the indoor temperature is controlled between 22-26°C;

[0059] (2) Multi-layer three-dimensional box racks are placed indoors, and several breeding water tanks are placed on each layer of breeding box racks, and the area of ​​the water tanks is 0.5m 2 Left and right, with a height of 33cm. Each water tank is independent and can share a water inlet system or a separate water inlet system. The lowest water level is determined by the position of the water outlet. The height of the water outlet is 5cm high;

[0060] (3) The water level of each water tank is controlled at 11cm and kept stable, the pH value of the water in the water tank is controlled between 6.8-7.2, and the dissolved oxygen is controlled above 5mg / L;

Embodiment 1

[0077] as attached Figure 2~3 As shown, a kind of Procambarus clarkii artificial cave comprises four PVC hard tubular nests 4 and non-toxic black plastic flat nets of different specifications after cutting to make the bottom surface 2, ceiling 1 and inner nest 3 of the artificial cave respectively. The overall length of the cave is 52cm, width is 25cm, and the maximum height is 11.5cm. Each PVC rigid tubular nest 4 is 15cm long and has an aperture of 5cm. The hole diameter of the black plastic flat net on the bottom surface 2 is 1.8cm, and the cut size is 52cm×25cm; the hole diameter of the black plastic flat net on the ceiling 1 is 1.2cm, and the cut size is 52cm×33cm; The aperture of the flat net is 0.3 cm, and can be cut into four sections from a piece of 52 cm × 33 cm plastic flat net, each section is 13 cm wide and 33 cm long. After cropping, press Attach figure 2 , 3 Assemble and fix.

Abstract

The invention relates to an indoor soilless procambarus clarkii culture method and an artificial cave for the same. The method comprises steps as follows: a multi-layer stereoscopic box rack is arranged indoors, and a plurality of aquaculture water tanks are placed on each layer of stereoscopic box rack; plastic aquatic plants and the artificial cave are arranged in each tank in proportion according to size of the tank, a long strip-shaped corridor is reserved between the artificial cave and the aquatic plants after the artificial cave and the aquatic plants are placed, baits are mainly thrownin the corridor, a few short and small passages are reserved in other places, and a small part of food is thrown to the passages; adult procambarus clarkia are cultured at the density of 30-40/m<2>,or juvenile procambarus clarkii are cultured at the density of 400-800/m<2>, or procambarus clarkii with larvae are cultured at the density of 2-4/m<2>; the baits are thrown once in the morning and evening every day. With the adoption of the culture method with controllable temperature, controllable illumination, controllable water level and controllable feeding, the demand of normal molting of procambarus clarkii for hidden things can be met by the artificial cave and with the method of plastic aquatic plant placement.

Description

technical field [0001] The invention relates to a method and a device for cultivating Procambarus clarkii, in particular to an indoor soilless cultivation method for Procambarus clarkii and an artificial cave thereof, belonging to the technical field of aquaculture. Background technique [0002] Proambaus clarkii (Proambaus clarkii) is native to the southern United States and northern Mexico. It is commonly known as crayfish. It belongs to Crustacea, Decapod, Crawfish family, and Proambaus genus. It was introduced into my country around 1929 and is currently in the Widely distributed in our country. The rapid growth of the market consumption and export volume of Procambarus clarkii has greatly promoted the development of the artificial aquaculture of Procambarus clarkii. Because Procambarus clarkii has special biological characteristics such as aggressiveness, strong territoriality, and love to dig holes. [0003] At present, paddy field farming of Procambarus clarkii and s...
