Description

INSTALLATION FOR CONNECTING WATER BODIES

The utility model relates to the field of industrial breeding of shrimp and can be used as a growing tank for growing planting material.

Known installations for the maintenance of aquatic organisms, including a tank with a main and false bottoms, a closed circulation system with a filter and pipelines with valves, while the false bottom is fixed on the sides of the tank with the formation of chambers between the bottoms (see, for example, a from the USSR) & 736917 class AOIK 61/00 for 1980).

Known installations are unprofitable for breeding shrimp planting material, because the mechanical separation of shrimp and feed organisms during water filtration and its purification leads to a significant reduction in the percentage of finished products.

Closest to the proposed technical solution in terms of technical nature and the effect achieved is the prototype installation for keeping aquatic organisms, which includes a tank with a section for placing aquatic plants and surfaces for holding the bacterial film, a light source, a pump, an aerator, and a piping system with shut-off elements ( see, for example, patent CM 5054424 for clo AOIK 63/04 for 1990).

The disadvantages of the described installation include the accumulation of dead feed organisms at the bottom of the tank, KOTOpie, decomposing, attaches to the bottom with a bacterial film and, when removed mechanically from the tank with a pipe, are separated from the cultivation objects, which also reduces the percentage of planting material output

The objective of the utility model is to eliminate these shortcomings and increase the survival rate of shrimp planting material.

The problem is achieved in that in the known installation for the maintenance of aquatic organisms, including a tank equipped with a bottom with a section for placing aquatic plants and surfaces for holding the bacterial film, a light source, a pump, an aerator and a piping system with shut-off elements, the bottom of the tank is made inclined, section for placement of aquatic plants it is a cellular cage with a bottom and side walls, and the surfaces for holding the bacterial film are collected in a disk bag and installed with zmozhnostyu with rotation about the axis, wherein the dimensions of the side walls of cells of the cage and its bottom vsholneny in a ratio I: 10, and the packet diszhovogo axis located above the water surface in the tank.

The solution to this problem is really possible, because the execution of the bottom of the tank inclined allows for a more high-quality removal of cord waste from the tank. Performing a cage with the indicated ratio of the sizes of the cell of the bottom and the side walls (determined by the ratio of the linear sizes of the feed organisms and the object of cultivation) provides free penetration into the volume of the cage of the feed organisms, evacuation from the volume of the cage through the cells of the bottom of the feed residues (weakened and dead zooplankton) and maintaining the planting density cultivation objects. Collected in a disk bag and mounted with the possibility of rotation around the axis of the surface to hold the bacterial film containing nitrifying aerobic bacteria, they act as a biological filter that converts toxic waste products of fodder organisms and growing objects into less toxic nitrates. All of the listed design features of the installation allow you to create the optimal gyrochemical regime of the content of cultivated objects, which increases the survival rate of shrimp planting material

The installation contains, for example, a tank I with a bottom 2 and a water level 3 made of polyvinylchloride or plexiglass. A tank 4 with side walls 5 and a bottom is placed in tank I. 6 made of a polymer mesh with different cell sizes. Above the water level 3, on the axis 7 with a step of 5 mm, disks 8 are installed, made, for example, of chemically inert materials (fiberglass, polyvinyl chloride, plexiglass) and forming a biological filter. A light source 9 is located in the upper part of the installation. In addition, the installation includes pipelines 10 and II for supplying and discharging water with shut-off elements 12 and 13, respectively, and air supply pipelines 14. The installation also contains thermostating equipment (not shown in the diagram).

The operation of the installation can be illustrated by the example of growing planting material of a giant freshwater shrimp Motttc

The tank of installation I is filled with water having the following parameters:

-temperature 28-i-3I ° G;

- salinity 1О12 ° / оо;

pH 7.0-8.5;

- content of nitrites Аi;: - X not more than 0.1 ppm;

-nitrate content - / J / no more than 20 ppi;

-Rpm general water hardness.

In cage 4, shrimp larvae with a density per liter are placed; a density of zooplankton (e.g., crustacean nauplii) of 5-I-I5 per ml and phytoplankton (e.g., 6S-e microalgae: &) is created

 cells per ml, rotate the disks 8 of the biological filter with an active bacterial film and turn on the air supply through pipelines 14.

positive phototaxis. Inactive and deadly zooplankton falls through the cell of the bottom 6 of cage 4 and settles on the inclined bottom 2 of tank I, from where it is periodically removed (eaten by other aquatic organisms, such as aquarium fish, and mechanically drained).

The water in reservoir I is changed daily in a volume determined by the permissible level of nitrate content and replaced by the volume of water withdrawn from the system when mechanical particles are removed.

The development of larvae under the described conditions lasts about 30 days, after which they become post larvae and go on to the bottom lifestyle.

during this period, the larvae are adapted to fresh water, gradually reducing the salinity of the water in the reservoir I, the cage 4 is removed from the reservoir I, and the larvae are placed in containers for transportation and commercial cultivation.

After cleaning Tank I and replacing the water, the unit is ready for a new growing cycle of planting material.
