You may use gaff hooks or landing nets to help you land fish. Hooks: When fishing by hook-and-line, you cannot use more than two lines or more than two hooks on each line when still fishing or trolling. When fly fishing, you cannot use more than two flies on one line. When you are trolling and bait casting, you cannot use more than two trolling spoons or artificial baits on one line. You can use a third line if you have a valid third line fishing permit. You cannot leave fishing line or lines with hooks in the water unattended by being out of visual sight of the lines. One hook is a single, double or treble-pointed hook, and all hooks attached as a part of an artificial bait or lure are counted as one hook. An Alabama (umbrella) rig is not an artificial bait or lure. Ice Fishing Shelters: Ice fishing shelters left unattended on land or water under the jurisdiction of the state, must have the owner's name, street address and city in 4-inch or larger block letters (in a color contrasting to their background) on all sides, but do not need to be registered. Attach reflectors to all sides of any shelter left on the ice after sundown. Keep shelters unlocked while in use. Remove shelters from all state-owned lands and waters by Feb. 20 or ice melt, whichever comes first, unless the deadline is extended. Tip-Up Fishing Device: A "tip-up" is an ice fishing device with an attached flag or signal to show fishing action, used to hold fishing line and a hook. You may fish a combination of one tip-up and one additional line, or two tip-ups and no additional lines. You can use an additional line or tip-up if you have a third line fishing permit.  When fishing the Mississippi, Missouri and Big Sioux Rivers and their connected backwaters, the following regulations apply: you can use up to three tip-up fishing devices. You can use two or three hooks on the same line, but the total number of hooks each person uses cannot exceed three. Each tip-up fishing device must have a tag attached, plainly labeled with the owner's name and address. You cannot use a tip-up fishing device within 300 feet of a dam or spillway or in a part of the river which is closed or posted against use of the device. Three tip-up fishing devices may be used in addition to two lines with no more than two hooks per line. Trotlines: "Trotlines" as used in this section refers to lines commonly called "tagged lines," "throw lines," "banklines,"  You can use trotlines in all Iowa rivers and streams, except those in Mitchell, Howard, Winneshiek, Allamakee, Fayette, Clayton, Delaware, Dubuque and Jackson counties. Trotlines may be used in the above nine counties only in the following stream sections: Mississippi River; Maquoketa River, mouth to Backbone State Park dam; North Fork Maquoketa River, mouth to Jones-Dubuque county line; Turkey River, mouth to Elkader dam; and Upper Iowa River, mouth to the first dam upstream in Winneshiek County.  You cannot use more than five trotlines with a valid sport fishing license. These trotlines cannot have more than 15 hooks total. Each separate line must have a tag attached, plainly labeled with the owner's name and address. You must check the line at least once every 24 hours. Remove all trotlines and parts from the shore if they are not being actively fished. A trotline is considered actively fished if at least once daily the trotline is left with at least one baited hook in the water. You cannot use trotlines in a stocked lake or within 300 feet of a dam or spillway, or in a stream or portion of stream which is closed or posted against its use. One end of the line must be set from the shore and visible above the shore waterline. You cannot set the line entirely across a stream or body of water. Any conservation officer can remove untagged or unlawful lines. Bow Fishing and Spearing: You can take nongame fish and frogs by bow and arrow and spear with a valid sport fishing license. Bow fishing and spearing are allowed on public lakes, reservoirs and rivers, private ponds with permission, and border waters. Some state parks, federal refuges and lakes controlled by city and county governments may have additional regulations specific to bow fishing and spearing. 

Total length means the straight line distance from the most forward point of the head with the mouth closed, to the farthest tip of the tail with the tail compressed or squeezed, while the fish is lying on its side.

The maximum number of individual fish legally harvested per harvester per day. Bag limits are only for properly licensed anglers actively harvesting the species.
