JUVENILE FISH BREEDING FACILITY Russian patent published in 2009 - IPC A01K63/00 A01K61/00 

FIELD: agriculture.

SUBSTANCE: structurally the facility is composed of the following: a tank filled with sea water; heating and cooling elements; lamps; a water circulation pump; biofilters; an oxygen blender; temperature and pressure sensors; a compressor; valves and a tubing system. The hydraulically insulated tank is equipped with a removable translucent lid with a leakproof sealant element and integrated lamp, a hatch for larvae inlet, a fodder delivery gate with the electronically actuated ingress and egress hatch lids. In addition the tank is equipped with a water level sensor, larvae motion sensors, an electronically actuated pressure reducer valve, light and sound alarm signal devices all connected to the control programme microchip of the mode setting console. A tubing system serially connects the tank to the water pump (with a pressure reducer valve, a flow gauge and a biofilter installed in the latter's manifold) and to the buffer reservoir equipped with water heaters, a heat exchanger with a cooler, a gas analyser and a gas blender, the latter connected to an oxygen cylinder. The water heaters, the temperature sensors, the pressure sensors, the gas analyser, the gas blender and the water pump equipped with a water scoop and a biofilter are equally connected to the control programme microchip of the mode setting console.

EFFECT: minimisation of losses in the process of juvenile fish breeding.
