FIELD: aquaculture.
SUBSTANCE: device includes a housing made of a polyethylene pipe with a diameter of 110-160 mm and two branches connected to it at both ends at an angle of 45°. Two mirrors focused together are mounted inside the bends of the branches to transmit the reflection of the observed illuminated area at the bottom of the pond from one end of the device to the other through a hole in the reflector of the spotlight with a glass attached to the lower branch. Light bulbs are integrated into the reflector body with power supplied by a rechargeable or non-rechargeable battery located outside the device body.
EFFECT: invention makes it possible to monitor behaviour of pond fish when feeding, control the consumption of feed, the progress of wintering in wintering ponds, and the health status of the fish.
