Download or read book Biology and Ecology of Pike written by Christian Skov and published by CRC Press. This book was released on 2018-01-09 with total page 411 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book sets out to bridge the order scales among pike researchers, populations, communities, management, and fisheries. It emphasizes the progress of pike research during the last two decades, during which the order-bridging approach emerged. This framework underpins the text and the message, to convey its importance to pike research and to fish research in general. In addition, a considerable part of the book is devoted to management implications and highlights aspects of human dimensions in recreational fisheries.
Download or read book Stock Assessment of Northern Pike in Harding Lake 2020 written by Laura Gutierrez and published by . This book was released on 2020 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: In Harding Lake, an updated estimate of northern pike abundance is needed to determine if the population is large enough to reopen the sport fishery. In this lake, the abundance of northern pike = 450 mm FL declined from roughly 2,500 fish in 1993 to 500 in 1999. This decline was attributed to a loss of rearing habitat in shallow vegetated littoral areas and prompted the sport fishery to be closed in 2000. In 2007, water was diverted from Rogge Creek to raise the lake level and re-establish northern pike habitat. As of 2012, the population had not rebounded to its numbers in the early 1990s, and the sport-fishery has remained closed. This study will estimate the abundance and length-composition of northern pike = 450 mm FL in Harding Lake using a two-event mark-recapture experiment to determine if, and in what capacity, the sport fishery is ready to be re-opened. The capture and recapture events will take place in June and August 2020.

Book excerpt: In Harding Lake, an updated estimate of northern pike abundance is needed to determine if the population is large enough to reopen the sport fishery. In this lake, the abundance of northern pike ≥ 450 mm FL declined from roughly 2,500 fish in 1993 to 500 in 1999.

Download or read book Estimated Abundance of Northern Pike in Harding Lake 2012 written by Klaus G. Wuttig and published by . This book was released on 2015 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: The abundance of northern pike >450 mm FL was estimated in Harding Lake during 2012 using a 2-sample mark-recapture experiment for a closed population. The first event occurred during May 29-June 7 and a combination of gillnets, fyke nets, hoop traps, and hook-and-line was used to capture fish. The second event occurred during August 7-14 and hook-and-line gear was used exclusively. Abundance was estimated at 567 (SE=47) northern pike >450 mm FL. The length composition was divided into 25-mm length categories and the 550-574 category represented the largest segment (16%) of the estimated population. Harding lake has been closed to fishing for northern pike since the summer of 2000 and the estimated abundance of northern pike during 2012 was well below the minimum level of 1,000 fish >450 mm FL needed to open the fishery to catch-and-release. The low population size is attributed to the chronic loss of shallow littoral areas with emergent vegetation and the associated poor recruitment, which was first evident during the most recent stock assessment in 1999. The last stock assessment during which good recruitment of age-3 and -4 fish was observed occurred in 1996 and corresponded to cohorts from 1992 and 1993 when the water levels ranged between 717.5-717.8 ft ASL. Therefore, this range should be used as a target for reestablishing water levels and historic pike production using the water diversion structure on Rogge Creek. Water level in 2012 was measured at 714.0 ft ASL.

Download or read book Stock Assessment of Northern Pike in Harding Lake 2022 written by Matthew Albert and published by . This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The abundance of northern pike Esox lucius ≥450 mm fork length (FL) was estimated in Harding Lake during 2022 using a 2-sample mark–recapture experiment for a closed population. The first sampling event occurred 1–3 and 6–10 June and the second occurred 10–12, 16–18, 23, 25, and 30 August. Hook-and-line gear was used exclusively in both events. Estimated abundance of northern pike ≥450 mm FL was 949 (SE = 114; 90% CI = 761–1,137). Northern pike 450–599 mm FL made up 58% (SE = 9%) of the estimated population and fish ≥600 mm FL accounted for 42% (SE = 11%). The water level at Harding Lake has increased over the past 7 years and is currently at the target elevation of 717 ft above sea level. The higher water level has created and improved habitat for northern pike. This abundance estimate demonstrates that the northern pike population is continuing to increase along with the water level.

Download or read book Picking Berries written by Jerry Lipka and published by Calgary : Detselig Enterprises. This book was released on 2004 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this module for grades two and three, students engage in a series of hands-on activities that help them explore data, graphic representation and linear measuring. Students gather data related to the berry harvest to build and analyze tables and graphs, and they learn to read thermometers and measure the length of their shadows. The culture and math of this module connect through an engaging story of a family gathering berries at the end of summer. About the Series Math in a Cultural Context This series is a supplemental math curriculum based on the traditional wisdom and practices of the Yup?ik people of southwest Alaska. The result of more than a decade of collaboration between math educators and Yup?ik elders, these modules connect cultural knowledge to school mathematics. Students are challenged to communicate and think mathematically as they solve inquiry-oriented problems, which require creative, practical and analytical thinking. Classroom-based research strongly suggests that students engaged in this curriculum can develop deeper mathematical understandings than students who engage only with a procedure-oriented, paper-and-pencil curriculum.
