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.

This book was released on 2002 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The Coeur d'Alene Tribe of lndians have proposed a westslope cutthroat trout, Oncorhynchus clarki lewisi, production facility to enhance adfluvial populations within the Coeur d'Alene Lake System. Westslope cutthroat trout are a species of special concern in Idaho. One of the limiting factors to be examined prior to implementing the trout hatchery was the potential for predatory fish to eat cutthroat trout after they migrated into Coeur d'Alene Lake. The annual feeding habits of the five major piscivorous fishes were examined from Coeur d'Alene Lake, the lateral lakes of the Coeur d'Alene River and lower sections ofthe St. Joe River, Idaho to determine the importance of the westslope cutthroat trout in their diets. Fish were collected by boat electrofishing, horizontal gillnets, vertical gillnets, and angling. Stomach contents were extracted from the stomach and preserved in 10% formalin. Fish remains in predator diets were keyed using diagnostic bones. Diagnostic bone length to total body length regressions were used to back calculate the original size of the prey fish. Of 493 stomachs examined, nine westslope cutthroat trout could be positively identified in the stomach contents. Six were in northern pike (Esox lucius) stomachs, two were from chinook salmon (O. tshawytscha), and one from a smallmouth bass (Micropterus dolomieui). Cutthroat trout were not found in any northern pikeminnow (Ptychocheilus oregonensis) or largemouth bass (M. salmoides) stomach samples. The average size of cutthroat trout consumed by these piscivores was 215 mm in total length, which correlates with the average size of a four year old in this system. The cutthroat trout consumed by predators in this study were likely first year spawners or making their first adfluvial migration into the lake from natal tributaries. In many chinook salmon and northern pikeminnow stomachs, salmonids were present, but could not be keyed to species due to extensive digestion and/or lack of diagnostic bones. Northern pike seemed to pose the biggest threat to migrating cutthroat trout. Northern pike are typically found in shallow water, as were cutthroat trout in this study. Westslope cutthroat trout were identified in 23% of northern pike stomachs analyzed (n=26). Chinook salmon and northern pikeminnow typically consume fish in pelagic waters; cutthroat trout were positively identified in 5% of chinook stomachs (n=43) examined and none were found in northern pikeminnow stomachs (n=227)"--Document.

This book was released on 2013 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: Adfluvial Westslope Cutthroat Trout Oncorhynchus clarkii lewisi populations have declined significantly since the 1900s in Coeur d'Alene Lake, Idaho. The Coeur d'Alene Tribe has an intense Passive Integrated Transponder (PIT) tagging program and has reported poor juvenile to adult return rates, which is hypothesized to be a result of predation by nonnative species, such as Northern Pike Esox lucius and Smallmouth Bass Micropterus dolomieu . Sampling occurred on 138 days and 15,645 individual fishes representing 24 species were captured. The population structure and dynamics of Northern Pike and Smallmouth Bass were similar across sampling locations. After pooling data for Coeur d'Alene Lake, growth of Northern Pike and Smallmouth Bass was compared using meta-analysis to other populations across their distributions. The potential effect of predation by Northern Pike on Westslope Cutthroat Trout was evaluated with bioenergetics modeling. Northern Pike (i.e., 2008-2011 year classes) consume an estimated 5,641 Westslope Cutthroat Trout annually from the four sampling locations (i.e., Cougar, Wolf Lodge, Windy bays, Benewah Lake) in Coeur d'Alene Lake.

This book was released on 2011 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The objectives of this study were to describe the growth of northern pike, describe the food habits of northern pike and using bioenergetics modeling assess the mass and total numbers of each species of forage fish the northern pike population consumed in Box Canyon Reservoir,Pend Orielle River, Washington. Northern pike (n=328) were collected by boat electrofishing, fyke netting, angling and gillnetting in 2009 and 2010. All northern pike were sacrificed to obtain stomach contents. Stomach contents were examined in the laboratory and identified to the appropriate level; amphibians and mammals to species, insect prey (aquatic/terrestrial) to family and prey fish to species. Using standard regression equations from Hansel et al. (1988) and those developed for the EWU bone reference collection the length of ingested prey items at time of ingestion were estimated. A standard set of regression equations were then used to convert the estimated length of forage fish to estimate their weight at time of ingestion"--Document.

This book was released on 2016 with total page 47 pages. Available in PDF, EPUB and Kindle. Book excerpt: Relative abundance, food habits, age, and growth of northern pike Esox lucius, were compared among 3 lakes known to rear juvenile salmon (Chelatna, Shell and Whiskey) in the Susitna River watershed and 2 additional lakes where juvenile salmon have apparently been extirpated, probably by a combination of northern pike predation and beaver dams that block adult migration (Redshirt and Trapper). Mean catch per hour (CPUE) in variable-mesh gillnets was used to estimate northern pike relative abundance in each lake. Mean gillnet CPUE differed significantly (P 0.001) among lakes and were lower in Chelatna and Shell lakes compared with the other 3 lakes. In lakes with salmon, northern pike diets were dominated by other fish and salmon (73%); whereas, lakes without salmon were dominated by invertebrates (91%). In lakes without salmon and other fish in diets indicated that all fish had been largely extirpated. Northern pike in Trapper Lake exhibited the highest rate of cannibalism. The number of juvenile salmon found in northern pike stomachs differed (P
