Fishsaverpro is an engineered release device for fish caught in deep water and suffering from decompression or Barotrauma. Data shows the highest survival rate for fish with barotrauma is by using descending device fishing technology for their release Studies show fish descender devices are a better alternative than using a fish venting tool. Small compact engineered design makes it safe and easy to store and use with the concept of ganging 2 or more units for multiple fish and not using a pressure release device means that the fish can swim off once it has reached recovery depth. Not being restrained means fish can swim free when in danger and reduces casualty through shark and predator attack during fish descent. Good for all fish caught at depth including red rock fish, grouper and red snapper fish. Fishsaverpro is supplied without weights and is patent pending. Size helps to minimise damage to the fish and the device is made from selected high corrosian resistant stainless materials for long life and durability.
