Guide

A plain-English guide to the terms in state fishing regulations, with real examples from Texas, Ohio and Minnesota.

Updated 2026-10-23

State fishing rules look dense because a few small ideas are stacked together. Once you can spot each one, a regulation table reads quickly.

The four ideas

Daily limit (bag limit). The most fish of a species you may keep in one day. Release the rest, or stop keeping fish once you reach it.

Possession limit. The most fish you may hold at any one time, which matters on multi-day trips. Some agencies set it separately. Texas, for example, says possession is generally twice the daily limit, with exceptions listed by species or water.

Minimum length. A fish shorter than the stated size must go back. Ohio’s statewide largemouth, smallmouth and spotted bass limit pairs a daily limit of five with a 12-inch minimum, so a fish that measures 11 inches cannot be kept even if you have not reached five.

Slot or size-restricted limits. Some rules protect a range of sizes, or allow only one fish above a size. Minnesota’s walleye limit, as printed for the 2026 season, allows only one walleye over 20 inches in your possession. Texas allows five walleye per day but only two under 16 inches. Both are the same idea written from opposite directions: a cap on how many fish of a given size class you may keep.

Check the fine print every time

  1. Which water are you on? Statewide limits are the starting point. Lake Erie in Ohio, Lake Superior in Minnesota and many individual lakes have their own entries that replace the statewide figure.
  2. Which dates? Several limits change during the year. Ohio’s Lake Erie bass limit shifts across spring and early summer, and Minnesota’s bass seasons open with a catch-and-release period.
  3. Species groups. Minnesota combines walleye and sauger in one daily limit, and Texas counts rainbow and brown trout together.
  4. Which license? Minnesota’s conservation license, for example, carries smaller limits than the standard angling license.

Each species page on this site shows the exact figures we read, the regulation period they apply to, the agency’s URL and the date we last checked. Treat them as a quick reference, and confirm with the agency’s current regulations before you keep a fish.
