摘要:

A method of measuring the areas of stream sections and a method of removing the fish therefrom are described. Cresol is used to render the fish helpless, and a formula is given for calculating the amount necessary for a treatment. The advantage of the new method lies in the fact that the fish can be removed from the stream, examined, and returned to the stream unharmed.
