Sinopsis

Excerpt from Twenty-First Annual Report of the Commissioners of Fisheries of the State of New York, 1893

At the suggestion of 'the commissioner in charge, fry were kept to be reared for breeding purposes, but in June an alarming mortality began among them, and nearly all died. A thorough investigation has been made into the causes for this mortality with the result of proving, at least to the satisfaction of the com missioner in charge, that it resulted from a want of sufficient fresh water and the high temperature of the ponds in which they were kept.
