Abstract
As a result of the water analyses and correlation with pound‐per‐acre rating for various fish, it was found that rainbow trout and other fish have a strong aversion to nickel and other heavy metals. Rainbow trout do not survive in water with more than 0.1 ppm nickel, whereas brook and brown trout can survive. It is believed that based on atomic absorption analysis of water it can be accurately predicted that water can be stocked with certain fish in order to assure maximum productivity and eliminate fishkill. These findings can be used by state conservation agencies as a guide in stocking streams and impoundments. The damming of a stream to form an impoundment without checking the composition of the tributaries may lead to the creation of a sterile impoundment. This is well illustrated by Matawan Lake in Matawan, N.J. Two tributaries to this impoundment contribute sufficient sulfuric acid and soluble aluminum to kill almost all of the animal and plant life.
