Description

The utility model relates to fish farming, and in particular to devices for the combined cultivation of viable juveniles of various fish species and aquaculture feed objects (daphnia, mine, rotifers, microalgae).

A known installation for growing juvenile fish, including a fish tank made in the form of a rectangular pool, divided by vertical partitions into compartments, a closed water circulation system with filters for rough and biological water purification, a pump, an aeration device, characterized in that vertical partitions are formed in the pool compartments - the main working compartment for juvenile fish, a filter compartment and a pump compartment, while in the partition connecting the working compartment with the filter compartment, there is a cutout in the upper edge of the fume ki through which water is poured, and in the partition between the filter compartments and the pump room at the bottom there is a slit-like slot for water overflow, a drain hole is mounted at the bottom of the pool at the partition, which is fenced off from the main volume of the working compartment with a frame with a small mesh net, which prevents juvenile fish from leaving the pool , the hole is equipped with a corrugated hose and a tee with an open upper pipe, to which a lanyard is connected with a lower hook, which ensures the adjustment of the amount of incoming and outgoing lips water inlet, while one of the tee nozzles is connected to a pipe diverted into the sewer, the pump compartment is equipped with an electric pump, and an overflow hole is made in the side wall of the compartment at a certain distance from the upper edge of the pool to prevent uncontrolled rise of water, and a nozzle with a tap for supplying fresh water, the pump is connected in series with pipes to a sterilizer, a thermoregulation unit and a tap for circulating water in the pool, above which at the end wall of the working compartment eplena cooling tower water operate aeration function (see. RF patent No. 110927, 2011).

However, it does not provide for the cultivation of feed objects.

The closest in essence is a compact fish breeding facility for closed water supply, containing pools, water shut-off devices and an electric pump connected to each other in a closed circulation circuit. The installation also includes an aeration and thermoregulation system, a level automation unit and a water level sensor. Accumulative and water pressure pools, as well as biological treatment pools, are located in the central part of the installation, communicated with each other and mounted in three tiers. Pools of loading, cultivation of feed, water reserve are located on the left and right side of the installation and are mounted in two tiers (see RF patent No. 2487536 2013).

However, the known device does not provide for the possibility of cultivating microalgae in a bioreactor as an additional source of biofeed.

The technical task is to create a device for growing viable juveniles of various species of fish based on the food base of cultivated objects together.

The technical result is an increase in the efficiency of growing planting material by improving the design of the device.

It is achieved by the fact that in the known device comprising pools connected to each other in a closed circulation circuit, water shutoff devices and an electric pump, aeration and temperature control devices, biological water treatment devices, a feed cultivation pool, and a juvenile rearing pool are equipped with a vertical longitudinal partition dividing different types of fish, there is an apparatus for growing microalgae, made in the form of a bioreactor, connected through an electric pump and a pipeline to the pool for growing Bani feed device for mechanical cleaning of water, formed as a filter and a conduit connected with a thermoregulation system.

The microalgae bioreactor is an effective device for rapid crop growth.

The proposed device is schematically shown in the drawing - FIG. one.

The installation contains a two-section pool 1 for rearing juveniles with a vertical longitudinal partition 2, connected through drainage holes 3 in series with a pipe 4 through a circulation pump 5 with a mechanical filter 6 and a temperature control system 7, a device for biological treatment of water 8, an aeration system 9 through the water isolation devices 10 and water supply holes 11 with pool 1. Pool 1 is connected by a pipe 12 through water supply holes 13 and pumps 14 through water drain holes 15 with 2 pools for growing feed 16, connected through a water supply hole 17 by a pipe 18 with an electric pump 19 through a water drain hole 20 with an apparatus for growing microalgae, made in the form of a bioreactor 21. To better increase the feed base above the feed cultivation pools, artificial lighting is used (not shown).

The installation works as follows: water from a two-section pool 1 for growing juveniles, separated by a vertical longitudinal partition 2 for growing different types of fish, is fed through drainage holes 3 through a pipe 4 through a circulation pump 5 in series to a mechanical filter 6, a thermal control system 7, a device for biological water purification 8, aeration system 9 through water-locking devices 10 and water-supplying holes 11 and returns to the pool 1. As necessary, from the bioreactor 21 through the weir openings 20 water with microalgae using an electric pump 19 is metered through a pipe 18 through water supply openings 17 into two pools for growing feed 16, of which through the drain holes 15 using pumps 14 through a pipe 12 water with biomass of feed organisms through water supply openings 13 is dosed served in pool 1.

The proposed device, the principle of operation of which is based on the joint cultivation of full-fledged live food and juvenile fish that are in close biological relationship with each other, on the basis of an integrated approach to the interchangeability of feed for different stages of development of the fish organism, allows for an interconnected feed chain: microalgae - zooplankton - larvae - juveniles fish, due to which in one system you can get high-quality products.
