HIGH-DENSITY AUTOMATIC APPARATUS FOR REARING EEL

摘要

PURPOSE:To control breeding conditions, shorten breeding period and reduce production cost by arranging assembly type artificial ponds crosswise side by side, sterically superposing the ponds, dripping pond water from the upper to the lower floors and spreading oxygen generating sand over the pond bottoms. CONSTITUTION:Water supply ports 3 with a filter are provided in assembly type artificial ponds and oxygen generating sand 6 is spread over the pond bottoms. Screw feeders 7, illuminators and water flow rate regulators are mounted to supply water passing through a gathering filter 12 with a pump 13, dripped from the upper to the lower floors and circulated. The water flow rate, water temperature, illuminance, feeding, etc., are controlled by a controller.
