Efficiency of Sampling Sunfishes Using Snorkeling in Clear, Warm-Water Streams of the South-Central United States

摘要: Abstract The continued evaluation of fish-sampling gears and methods is essential to identify their applicability across environmental conditions among species. Although limited by visibility, snorkeling has potential advantages relative other in wadeable streams (e.g., minimally intrusive, cost effective, appropriate deeper areas). Clear water common warm-water streams; however, the use for monitoring stream-fish populations largely focused on cold-water systems. To assess efficiency streams, we compared standardized single-pass snorkel counts tow-barge electrofishing abundance estimates six sunfishes (Centrarchidae) Ozark Highlands ecoregion northwest Oklahoma southwest Missouri under relatively similar (i.e., clear water, cobble substrates, low-flow conditions). Snorkeling was variable consistently low species with cryptic traits an...
