The closed and controlled environment consists of a filter chamber, which enables the flow of water to the interior of four compartments. The first compartment (1) is the receptor, followed by filtration through gravel (2), filtration through "Perlon" (RTM) and the fourth chamber is for the distribution (4). The filter chambers are provided with a system (6) for the recovery of sedimentation. The volume of the filtration system determines the number of tanks, which can be supported. The tanks also have a system (6) for the recovery of sedimentation and a system for the circulation of the water through gravel. USE/ADVANTAGE - It allows complete control of the environment for the rapid and successful development of the crayfish. |
