Fish Stocking and Management

Monday, September 29, 2008

This week we will follow up last week's fish kill discussion with discussion of fish biology and stocking. Some may have a new pond while others want to start over if a pond's fish population and diversity is undesirable.

Due to the flood of June 2008, many ponds were altered. If you are unsure of the status of your pond, the way to find the answer is fun. Go fishing and see what you catch!

Similar to land support capacities like one horse to two acres or one cow/calf pair per acre or 170 bushel corn per acre yield averages, ponds have production averages and characteristics.

The average Indiana pond supports 320 pounds of fish per acre varying from 109 to 703 pounds of fish per acre in a study of 14 Indiana ponds.

State and federal fish hatcheries no longer sale fish for private ponds as those fish are only placed in public waters. Fall is the best time to stock fish primarily due to the fact that most private hatcheries are setup to sell fish during the autumn time period. However fish can be stocked most any time of the year. If one has a new pond, it is best to stock it as soon as it becomes filled before someone dumps bait or some other fish species gets started proving stocking to be difficult.

It is absolutely a myth that undesirable fish species can enter a pond via fish eggs being carried on the feathers, wings or webbing of waterfowl.

The initial stocking ratio widely successful in Indiana consists of five bluegill fingerlings to one large mouth bass fingerling, not to exceed 1,000 bluegill and 200 bass per acre. For a low fertility pond, it would be good to keep the same ratio but cut the numbers by up to one half. Fingerling stocking sizes should be one to two inches for blue gill and three to four inches for bass. Channel catfish should be stocked at 100, four to six inch fish per acre. If redear are desired, substitute one-fourth of the bluegill fingerlings with one to two inch redear fingerlings. If hybrid sunfish are desired instead of bluegill or redear, a 10:1 ratio of sunfish to bass would probably be more suitable. In this scenario, the maximum stocking rate would be 1,000 sunfish and 100 bass per acre.
