Aerated transport tank for living fish - has water circulated by immersion pumps to provide necessary oxygen enrichment

摘要

The procedure is used for the aerated transport of living fish in large tanks. The water is circulated by pressure pipes above the water level using immersion pumps. The amount of circulation is sufficient to give an enrichment for the water which has the necessary life maintaining value for the transported fish. Specifically in the transport tank (1) below the water level (W) there are electrically driven immersion pumps (3) and the output of each pump (3) is connected to a pressure line under the cover (1') of the transport tank (1).
