For instance, a slot limit of 13 to 16 inches means you must, by regulation practice catch-and-release on the fish in the slot. Slot limits are special regulations used on specific bodies of water.

Texas rig (Texas-rigged) – The method of securing a hook to a soft-plastic bait, such as a worm, lizard or crawfish, so that the hook is weedless (doesn’t protrude). Typically, a slip sinker (often a bullet sinker) is threaded onto the line and then a hook is tied to the end of the fish line. The hook (often an offset hook) is inserted into the head of the soft-plastic bait for about one-quarter of an inch and brought through until only the eye is still embedded in the soft-plastic bait. The hook is then rotated and the point is embedded slightly into the body of the soft-plastic worm without coming out the opposite side. Many anglers try to ensure the bait stays straight once it is Texas-rigged.

thermocline – A distinct layer of water where rising warm and sinking cold water meet but do not mix. It is a layer of water where the temperature changes at least one-half a degree per foot of depth. In many of our desert bass lakes, a thermocline often develops during the spring and breaks down in the fall. The colder layer of water is often lacking in oxygen, forcing most baitfish and sport-fish to the upper layer of water. Thermoclines can be so dense that they actually show up on sonar (fish finders and depth finders) as a thick, impenetrable line.

trailer hook – The extra hook or cheater hook added to a single-hook lure, such as a spinnerbait or weedless spoon. Also called a stinger hook.

transducer — A device that converts electrical energy to sound energy, or the reverse. Typically associated with depth finders or fish finders.

treble hook – A hook with a single or bundled shaft and three points.

tributary – A creek, stream, or river that feeds a larger stream or river, or lake.

triggering – Using a lure-retrieval technique that causes a sport-fish to react and strike. For instance, quickly speeding up a retrieve and then stopping. Can also referred to as causing a reaction bite.

trolling – Towing a lure or several lures behind a boat. When a fish is caught on the trolled lure, the boat is typically stopped and the fish is reeled in.

trolling motor – A small electric fishing motor, typically mounted on the bow, which is used as secondary means of propulsion for positioning or maneuvering a boat quietly in fishing areas.

tubing – A float fishing term that means to float down a river, stream or using a float tube in a lake while fishing.

turnover – In Arizona’s warmwater lakes, a turnover is typically experienced in the fall and is a phenomenon associated with thermoclines. In this case, the warmer layer of water at the surface cools down, and becomes colder than or as cold as the distinct layer of coldwater below. The result is that the two layers of water mix, eliminating the thermocline and creating a fairly uniform water temperature and perhaps introducing oxygen to the lower levels of the lake. This fall turnover action can result in bottom sediments nutrients being stirred up by the water movement, sometimes stimulating algal growth. The fall turnover typically signals the transition to winter fishing conditions.

ultralight – Lighter than standard fishing rod and/or tackle.

ventral fin – The paired fin located on the front of a fish’s abdomen.
