Evaluation of muskellunge and tiger muskellunge stocking program project f-113-r annual report to evaluation of muskellunge and tiger muskellunge characteristics such as forage species abundance and size, predator density and size distribution, and thermal regime. The abundance of sub-yearling salmonids that could be supported ranged 130,000–330,000 for each of the individual reservoirs however, investigation into the behavior and growth of juvenile anadromous salmonids in the reservoirs would refine these estimates. The upper st lawrence river is widely known for its world-class great lakes strain muskellunge (esox masquinongy, mitchell) fishery this population has been proactively managed through the efforts of an international st lawrence river esocid working group that led to the development of muskellunge management plans (panek 1980, lapan and penney 1991) and a more recent update (farrell et al.
The muskellunge angler diary survey in lake of the woods has proven to be an important source of data with which to index long-term trends in relative abundance and to evaluate impacts of changes in angling regulations on this fishery. The non-tidal james river 2015 this section is known for its abundance of smallmouth bass, trophy-sized muskellunge, and scenic mountain views the middle james (lynchburg to boshers dam in henrico) flows through the piedmont of virginia, is the flattest portion of the. Distribution, abundance, and survival of age-0 muskellunge esox masquinongy were evaluated at 10 bays in the thousand islands section of the st lawrence river over a 7-year period, 1990–1996. Thus, a slight reduction in muskellunge abundance would help accomplish goals 2 and 3 the biennial muskellunge stocking program should continue, but the stocking density should be reduced from 3-5 fall fingerlings/acre to 2 fall fingerlings/acre.

From an ecological perspective, predation, competition or resource partitioning, and abiotic factors interact to affect species distribution and abundance. The wide range in size classes of mature muskellunge, the widespread distribution of potential spawning habitat and catch rates comparable to other locations sampled with this methodology suggests that the moon river delta muskellunge populations are well established in the area. In fact, an analysis of muskellunge recruitment measured from 1962 to 1977 revealed that 55 % of the annual abundance of young muskellunge could be explained by the number of yearly stocked individuals and the abundance of young muskellunge stocked the previous year (cannibalism. Muskellunge that are used to produce both purebred musky and tiger musky offspring derived from these broodfish are utilized, in part, to meet management stocking requirements statewide. Muskellunge ranged in size from 27-40 inches with the majority of the catch from 30-34 inches this is a good sign of recent stockings being successful and new year classes moving into the population graph showing the size distribution and abundance of largemouth bass sampled devin with a 20-inch smallmouth.

Length frequency distribution of tiger muskellunge and muskellunge trap netted in nockamixon lake in april, 2015 the abundance of pure muskellunge in nockamixon lake was remarkably high in 2015 due to exceptional survival of the advanced fingerlings stocked by mi50 in 2012. Traps are placed at fyke net locations in nine study lakes (allequash, big muskellunge, crystal, sparkling, trout, mendota, monona, wingra and fish) crayfish traps have been eliminated as gear in the madison area lakes (mendota, monona, wingra, and fish) after 2003. Western ii region staff of three biologists are responsible for fishing areas in washington and frederick counties and the nontidal potomac river and tributaries the nontidal potomac river, or “upper potomac” as it is usually referred, provides excellent fishing opportunities for smallmouth bass, walleye, muskellunge, and channel catfish.
The objectives of the survey were to: 1) evaluate the abundance and size structure of the tiger muskellunge population and 2) evaluate the abundance and size structure of the walleye population in conjunction with electrofishing data collected on april 2, 2013. The infertile nature of tiger muskellunge makes the species a good candidate for introductions and stocking because fisheries managers can effectively control their abundance tiger muskellunge are also thought to be easier to catch because they are more eager than muskellunge or northern pike to bite at a lure or bait. All muskie that were caught with a pit tag and applied a pit tag in 2015 were considered tagged during the 2015 spring assessment for population abundance modeling purposes therefore, 36 of the 37.
Southeastern naturalist 13(3):506-514 2014 https: the efforts by twra to expand the distribution of muskellunge into non-native waters are similar to past and present efforts elsewhere in north america and abundance of pellet-reared and minnow-reared muskellunge stocked in northwestern iowa.
