Thus, Blue Catfish require many years to reach these potentially large sizes.īlue Catfish can live 20–30 years (Boxrucker and Kuklinski 2006 Holley et al. In Oklahoma reservoirs, it takes Blue Catfish between 13 and 16 years to reach a preferred size of 762 mm TL (Boxrucker and Kuklinski 2006). Truman Reservoir (hereafter, “Truman Reservoir”), Missouri, it takes Blue Catfish 6–7 years to reach 381 mm TL (Sullivan and Wallendorf 2007), a typical minimum harvestable size for many anglers (Sullivan 2014). This species attains large sizes (>45 kg), but recent evidence indicates that these fish grow slowly (Boxrucker and Kuklinski 2006 Holley et al. We recommend the 610-mm limit instead of the 660-mm limit because it allows more harvest and higher yields with increases in natural mortality and still doubles the proportion of larger fish relative to the 508-mm limit.īlue Catfish Ictalurus furcatus provide popular sport fisheries in many large rivers and reservoirs. All three length limits increased the proportion of larger fish (≥762 mm TL) in the population without reducing yield, except for slight decreases (6% and 10%) under the 610- and 660-mm limits at the highest modeled natural mortality rate. Using reward tags, we estimated exploitation to be between 8% and 12%, and we modeled the effects of 508-, 610-, and 660-mm minimum TL limits on yield and size structure of the Blue Catfish population relative to a baseline of 381 mm TL, the smallest fish usually harvested by anglers. Annual mortality was estimated at 24.8% using a weighted catch curve. Blue Catfish grew slowly, reaching a preferred size (762 mm TL) in about 12 years. We sampled Blue Catfish by using jug lines baited with pieces of Gizzard Shad Dorosoma cepedianum, the gear used by the majority of anglers in this reservoir. Our objectives were to (1) determine population demographics of Blue Catfish, (2) determine exploitation of Blue Catfish, and (3) determine whether new harvest regulations would improve the quality (e.g., size structure and abundance) of the fishery in Mark Twain Lake. Water in upper lake was dirty.Blue Catfish Ictalurus furcatus provide a popular sport fishery in Mark Twain Lake, Missouri, but little is known about their population demographics or exploitation by anglers.
If we don’t have shiners there is a small chance one of the other bait shops in the area still have some left.įished yesterday crappie were slow and scattered tough day for crappie whites were good.Girlfriend and I caught our limits on crappie but lots of spots to catch them. When we can’t get them we carry chubs, which are usually but not always smaller than shiners. Most of the time we carry medium shiners. Ron, do you carry any bait fish larger that crappie minnows like shinners or chubs? Has anyone seen any teal on Mark Twain Lake or thereabouts? You can skip to the end and leave a response.

If you have questions about the event, please contact Allen Mehrer at the Mark Twain Lake Project Trucks to haul materials from the locations, so if you have this equipment available, please consider Where the materials will be sorted to reclaim items that can be recycled. The collected trash will be returned to Spalding Boat Ramp To be provided locations to pick up trash. Participants will meet at the Spalding Boat Ramp at 8:00 am Organizations are needed to pick up trash along the lake shoreline, and along the roadways thatĪccess the public lands around the lake.

Septem– Mark Twain Lake will host a lake clean-up special event in association with Mark Twain Lake National Public Lands Day Special Event
