Final Thoughts

The Southern Sennet fish is often targeted by local anglers looking for a sporting challenge, though it does not usually end up on dinner tables in large numbers. While this species contributes little to commercial fishing, recreational fishermen still enjoy their efforts to catch these elongated predators with sharp teeth.

When handled correctly after the catch, the fish is generally safe for human consumption. However, occasional reports have linked larger individuals to a toxin that can cause illness in some. In the end, though the Southern Sennet plays a minor role in our region’s fishing industry, it remains a worthy quarry that tests the skills of amateur anglers willing to do battle on hook and line.
