Field and Laboratory

Publication Date



In the pages that follow, we include the proper construction of ponds and lakes for fish life, and an explanation of the water-conditioning process; the selection of fish to be used in ponds as well as lakes, with suggestions as to suitable combinations according to the dictates of limited experience; an account of the care of fish, feeding habits, maintenance of food supply, supplemental brood ponds, minnow ponds, methods to be used in producing accessory foods (such as Daphnia and midge larvae); and a discussion of predator control. Finally, there is a series of illustrations of the more common freshwater fishes with brief descriptions which emphasize field characters. These will enable the fisherman to tell what kind of fish he has caught. Information secured by other investigators has been drawn on freely and in these cases full credit is given. It is our desire to give fishermen something helpful and usable.
