You may possess no more than the daily limit of any given species while you are on waters, or on the banks of waters, where daily limits for those species apply. Any species taken into actual possession, unless released unharmed immediately after being caught, shall continue to be included in the daily limit of the taker for the day.
Where only catch-and-release fishing is allowed, fish must be returned unharmed immediately to the water after being caught.
The possession limit is twice the statewide daily limit. Fish you take and possess must be kept separate or distinctly identifiable from fish taken by another person. If you are away from your catch, the device holding the fish must be plainly labeled with your full name and address.
Many fish species and fishing areas have length limits.
A minimum length limit means that fish below a designated length must be returned to the water unharmed immediately after being caught.
A slot length limit or protected length range means that fish within a designated length range must be returned to the water unharmed immediately after being caught.
A maximum length limit means that fish above a designated length must be returned to the water unharmed immediately after being caught.
Regardless of where taken, fish that are not of a legal length cannot be possessed on the waters or banks where length limits apply. The head and tail must remain attached to the fish while you are fishing on waters where length limits apply.
Learn how to measure fish correctly.
The fish you catch in Missouri, or elsewhere, may be possessed and transported as your personal baggage, if you have the required permit. Fish may be stored, preserved or refrigerated only at your home, camp, place of lodging or in a commercial establishment. Stored fish must be labeled with your full name, address, permit number, species of fish and the date placed in storage. Fish taken in another state by methods not permitted in Missouri may not be possessed on waters of the state.
