Food Utilization by Riverine Smallmouth Bass in Relation to Minimum Length Limits

Food habits of smallmouth bass (Micropterus dolomieui) in the New River were studied to compare diet of fish in a minimum length limit regulated section (Virginia) with those in a non-length limit regulated section (West Virginia). Insects were the dominant food type by number for 152-228 mm smallmouth bass in both sections. Numerically, insects were also found to be common in smallmouth bass of several other size categories.

Angler Catches from New River, Virginia and West Virginia, in Relation to Minimum Length Limit Regulations

A 1-year creel survey of New River, Virginia and West Virginia, was conducted to assess the effects of a 305-mm minimum length limit on the angler harvest of smallmouth bass (Micropterus dolomieui) and associated fishes from the Virginia portion of the New River. Anglers in Virginia harvested 0.06 smallmouth bass per hour averaging 322 mm total length (TL) and released 1.27 smallmouth bass per hour. West Virginia anglers harvested 0.40 smallmouth bass per hour averaging 242 mm TL and released 0.65 smallmouth bass per hour. Total catches per hour (1.33 in Virginia and 1.05 in West Virginia...
