Crappie anglers, like all anglers, want to catch bigger crappies. Many assert that increasing fishing effort, especially the numbers of anglers employing superefficient techniques like spider-rigging, are depleting crappie numbers before they grow to large size. The increasing use of forward-looking sonar like Garmin Panoptix, allowing anglers to target the biggest fish and increase size-selective harvest, adds to the fury.

Invasive carp conjure up mental images of flying fish and hyperabundance. Millions are spent annually to control and curb the spread of black carp, silver carp, and bighead carp. Specifically, bigheaded carps (silver carp and bighead carp) are highly-publicized, abundant, and their impacts are well understood in established regions such as in the Mississippi River basin. In the Grand Lake/Neosho River system, invasive carp are in low abundance, and thus locating and removing them are difficult.

Sunlight drives photosynthesis, and oxygen is a product of that process. So is more oxygen found around and under floating vegetation than in nearby open water? Researchers at the University of Washington measured dissolved oxygen concentrations under and near thick mats of vegetation in two ponds.* In Bull Lake, mats of mixed coontail, milfoil, and Elodea produced high concentrations of dissolved oxy­gen at the surface (15 to 21 parts per milllion) during the day.

There’s a lot of chatter these days about live-imaging sonar (aka, live-scope, forward-facing sonar). Live-imaging sonar (LIS) has been quickly adopted by many crappie anglers; and there is concern among anglers, guides, and fishery managers that the increasingly common use of LIS may cause declines in crappie populations.

Powered by Strike King and Lew’sStocking is a common fishery management tool and is extensively used in black bass management programs. An average of 426,000 fingerlings and 32,000 advanced-size smallmouth bass are stocked annually into lakes and reservoirs in 12 states. Another of 129,000 fingerlings and 10,000 advanced-size smallmouth bass are stocked into rivers and streams in six states.
