Self Contained Underwater Breathing Apparatus (Scuba) As An Aid In Fisheries Work

The development of self-contained underwater breathing apparatus (SCUBA) in recent years has opened an entirely new world to those who are physically able to enjoy it. SCUBA is now used extensively in marine biology and is beginning to find its place in fresh water fisheries research and management. More aquatic biologists would probably utilize SCUBA if they were more familiar with its possibilities and its limitations. It is the purpose of this paper to present information which will assist fisheries administrators and biologists in determining whether or not diving techniques could be used in their programs.
