If there is evidence that the harvest is negatively affecting the size, growth rate or age distribution of that species, fisheries regulations are adjusted to protect the population through slot limits or limits on fishing gear. While many anglers in Indiana are fishing for recreational purposes, there are also anglers that fish for subsistence. Fishing provides a healthy and inexpensive means of supplementing food resources. If you have further questions about a particular species or location, please feel free to refer them to the fisheries biologist who covers the counties of interest. There are no restrictions on fishing hours.
Some lakes do have restrictions on boat speeds during certain hours.
The Fishing Guide provides information on current fishing regulations and allowable gear. Eligible species for the official competition are on an established list of the most common sportfish in Indiana. Recent additions to this list have been significant species that have been introduced to the state in the past several decades. You are welcome to submit an entry from a species not on the list, as the information may be useful to fisheries biologists in determining the sizes of various fish species in Indiana. However, it is unlikely that a fish species not on the list will be entered in the official competition.
