Walleye and Northern Pike
Introductions of nonnative walleye (Stizostedion vitreum) and northern pike (Esox lucius) have created popular recreational fisheries in many Northwestern waters. Rising demand for expanded angling opportunities for these species, especially walleye, has been met with growing concern about longterm risks associated with the introduction of a top predator. Proposed introductions are often contro...
متن کاملPrey Capture and the Fast-start Performance of Northern Pike
Fast-start performance of northern pike Esox lucius (mean length, 0.38m) during prey capture was measured with subcutaneously implanted accelerometers. Acceleration-time plots and simultaneous high-speed cine films reveal four behaviours with characteristic kinematics and mechanics. The fast-start types are identified by the number of large peaks that appear in the acceleration-time and velocit...
متن کاملAnatomical, histological and histomorphometric study of the intestine of the northern pike (Esox lucius)
Background: The northern pike Esox lucius is a fresh water species belonging to the Esocidae family. It is a carnivorous fish which mostly feeds on invertebrates and fishes. The morphology of its intestine is very useful for understanding the fish’s digestive physiology, diagnosing some intestinal diseases and formulating suitable feeds. OBJECTIVES: This study was designed to determine the anat...
متن کاملMitochondrial DNA variation in wild and hatchery populations of northern pike, Esox lucius L.
Esox lucius is an economically important freshwater species. Mitochondrial cytb, 12SrRNA, and 16SrRNA gene sequences were used in order to clarify the genetic variation and population structure in three E. Lucius populations, i.e., one Wild population (W) and two hatchery populations (Hatchery Population I-HPI and Hatchery Population II-HPII). A total of 55 individuals, with 19 from wild and 1...
