The Mississippi Interstate Cooperative Resource Association (MICRA) mandated that all hatchery-reared Paddlefish must be tagged with binary-coded wire tags (CWT) before stocking throughout the Mississippi River basin. Twenty-two (22) states participated in the tagging, but numerous states have expressed concern about CWT retention. This study was initiated to inform these concerns by estimating the proportion of tagged Paddlefish stocked in MDC managed ponds that retain binary coded-wire tags (CWT) after 10 years.

Reservoirs are important resources utilized by thousands of freshwater anglers annually, but as these reservoirs age, their physical habitat deteriorates and fish habitat quality is reduced. In 2007, a large scale habitat improvement project began on Table Rock Lake, Missouri with the goal of supplementing existing fish habitat in this large reservoir. Over 2,000 habitat structures composed of cedar, pine, hardwoods, stumps, and rocks were installed between 2007 and 2013. SCUBA surveys were used to evaluate black bass and crappie use of the installed habitat structures to determine if use of structures varied among fish species, fish size, season, and structure type.

Recruitment of black bass Micropterus spp. in large reservoirs is often related to fluctuations in water levels, although the specific mechanism driving recruitment is not known. Eastern red cedar Juniperus virginiana brush was added to coves within Bull Shoals Lake to replicate habitat conditions present during high water events in an effort to increase numbers of nesting adult black bass and abundance of age-0 black bass.

As reservoirs age, fish habitat may decrease because of increased siltation and deterioration of structures which may affect fish populations. Over the past five years the Missouri Department of Conservation (MDC) has worked to improve reservoir fish habitat in Table Rock Lake, Missouri. Over 2,000 fish habitat structures (e.g., tree, stump, and rock piles) were distributed and geo-referenced in an attempt to improve fish habitat and angler success. Researchers then surgically implanted 70 Largemouth Bass with radio telemetry transmitters and relocated them once a month during the day and night for one year.
