Mud minnows are similar to finger mullet in several ways, such as in size, often color, and even the fish species that eat them. Ranging from salt water coastal areas on farther into the estuarial system where the water becomes mildly brackish, mud minnows are generally easier to spot during lower tides. Mud minnows sometimes call bull minnows; spend most of their time in shallow water, often ten inches or less. In much the same manner as finger mullet, mud minnows will disturb the surface of the water as they move about giving their location away, thus like finger mullet, mud minnows can be caught using a cast net.
These minnows are however, different from finger mullet in several key ways. First, mud minnows are not migrate, they stay in local waters year round making them available as bait at anytime. As water temperatures drop, they become the most accessible bait on hand. This fact alone makes mud minnows a prime enticement for hungry fish in the colder months.
Secondly, these minnows can be caught using a baited minnow trap. This is very handy if there is time to set the traps and let them do their job. Bait a couple of minnow traps with bacon, locate a spot where the minnows are hanging out and place the trap there. Remember that mud minnows like shallower water so don't place the trap in deep water. The traps may also be baited with hot dogs, shrimp, or a piece of fish.
The mud minnow can be fished using any of the standard methods. Most often a 2/0 circle hook is adequate, but more importantly choose a hook size that will allow the minnow to be hooked through the lips or eyes and remain alive. Expect to catch redfish, flounder, spotted trout, or even large mouth bass.
In the spring as flounder prepare for their migration into local inlets, they will hold up on near shore reefs. Mud minnows are particularly effective when used to catch these schooled bottom feeding flounders and in this case, the flounders don't care if the minnows are alive, dead, or even frozen.
