Book Abundance and Composition of the Northern Pike Population in Minto Lakes 2003

Download or read book Abundance and Composition of the Northern Pike Population in Minto Lakes 2003 written by Brendan P. Scanlon and published by . This book was released on 2006 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abundance and composition of the northern pike, Esox lucius, population within the Minto Lakes study area was estimated using mark-recapture techniques during middle to late July 2003 to determine if estimated harvests within a specified reporting area exceed 20% of the estimated abundance as prescribed in the management plan.

Book Abundance and Stock Composition of Northern Pike in Minto Flats 1991

Available in PDF, EPUB and Kindle. Book excerpt: Study to determine abundance, length and age composition by means of mark-recapture experiments of northern pike (Esox lucius) in the Minto Flats region of central Alaska.

Book Estimated Abundance of Northern Pike in Minto Lakes 2008

Download or read book Estimated Abundance of Northern Pike in Minto Lakes 2008 written by Philip John Joy and published by . This book was released on 2009 with total page 37 pages. Available in PDF, EPUB and Kindle. Book excerpt: A two-event mark-recapture experiment was conducted on northern pike Esox lucius in Minto Lakes, Alaska during June 2008. Abundance was estimated for two areas; Area-A that included all water bodies that drained into Goldstream Creek from the Minto Lakes and Area-B, the historical assessment area that is a subset (approximately 64%) of Area-A waters. Fish were sampled and marked between May 29 and June 7, 2008 and recaptured from June 11 to June 20, 2008. Gear used included hoop nets, fyke nets, gillnets, and hook-and-line. Bias in estimates are discussed and it is recommended that future stock assessment projects attempt to sample all of Area-A. Calculated exploitation rates appeared to be at or near the 20% threshold set forth by the management plan.

Book Estimated Abundance of Northern Pike in the Chatanika River and Minto Lakes 2018

Download or read book Estimated Abundance of Northern Pike in the Chatanika River and Minto Lakes 2018 written by Matthew Albert and published by . This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: A three-event mark-recapture experiment was conducted on northern pike Esox lucius in Minto Flats, Alaska from March through August 2018. Abundance was estimated for 2 specific populations: 1) an overwintering population residing in the Chatanika River upriver from its confluence with Goldstream Creek, called the Chatanika River Overwintering Area (CROA); and 2) a summer population occupying a wetland complex defined as the Minto Lakes Study Area (MLSA). Fish were sampled and marked in the CROA from 7-23 March 2018 and 12-21 June 2018 in the MLSA. Recapture events occurred in the MLSA from 12-21 June 2018 (concurrent with marking) and 7-16 August 2018. One-hundred radio tags were deployed during March 2018 to evaluate movements of northern pike relative to the mark-recapture experiment. Two models were used to estimate abundances: a traditional two-event Petersen mark-recapture model for closed populations, and a multinomial Bayesian model. The Petersen model abundance estimate of fish ≥600 mm fork length (FL) in the CROA was 14,817 (SE = 1,836) and for the MLSA was 11,956 (SE = 5,836). The Bayesian multinomial model abundance estimate for fish ≥600 mm FL in the CROA was 14,675 (SE = 1,631) and for the MLSA was 11,443 (SE = 1,651). The Bayesian multinomial model generated more precise estimates because it used data from all sampling events and incorporated information from the radiotagged fish. There were significantly more northern pike in the MLSA than what was found in 2008. Biases in the estimates were addressed and the 2 modeling approaches were evaluated. The current exploitation rate of northern pike in Minto Flats is 7.3%, which is well below the maximum threshold stipulated by the joint sport and subsistence fishery management plans.

Book Estimates of Some Vital Statistics of Northern Pike Walleye and Sauger Populations in Lake Sharpe South Dakota

Download or read book Estimates of Some Vital Statistics of Northern Pike Walleye and Sauger Populations in Lake Sharpe South Dakota written by Joseph H. Elrod and published by . This book was released on 1969 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: Catch-effort data derived from gill net samples were used to estimate relative abundance, age composition, sex ratio, growth rate, survival rate, and relative year-class strength of northern pike, walleye, and sauger populations in Lake Sharpe, Missouri, S.D., during the first three years of impoundment (1964-1966.). Catches were generally highest in Oahe Dam tailwaters. Females were more numerous and larger at most ages than males.
