WATER CIRCULATION AND FILTRATION TYPE FISH AND SHELLFISH-CULTURING APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a water circulation and filtration type fish and shellfish-culturing apparatus that can control the temperature of the culturing water in low cost and can be size-miniaturized. SOLUTION: The water circulation and filtration type fish and shellfish-culturing apparatus is equipped with the tank 1 for culturing fish or shellfish, a tank group for water purification at least comprising the precipitation tank 6 for removing foreign substance included in the breeding water from the culturing tank 1 and the filtration tank 7 in which the breeding water from the precipitation tank 6 is filtered with a filter medium treated with microorganisms are attached to remove ammonia components dissolved in the breeding water and the circulation path that at least have a water temperature adjuster 23 for adjusting the temperature of the purified breeding water to a prescribed one and the breeding water is utilized as it is circulated through the circulation path. In this case, the tank group for water purification are arranged on the outside of the culturing water tank 1 so that they may tightly be contacted to each other and the area lower than the lowest water level of the breeding water in the culturing tank is covered with the tank group for water purification 4.
