The fish mostly consumed by otter were Cyprinus carpio (carp) (37.22%), Tinca tinca (tench) (21.53%), and
Esox lucius (pike) (7.62%), respectively.
The present study validates the aging method for larval northern pike (
Esox lucius), a species of significant importance for both commercial and recreational fisheries and having a wide circumpolar distribution (i.e., in North America and Europe) (Craig, 2008).

Effect of osmolality on sperm morphology, motility and flagellar wave parameters in Nothern pike (

However, cormorants have been reported diving as deep as 35 m (Gremillet et al., 2006) and may consume large prey (as large as 308 mm standard length in this study) including Sander vitreus (Madenjian and Gabrey, 1995;Johnson et al., 2002; Rudstam et al., 2004; this study),
Esox lucius (Fowle 1997; this study), greater redhorse (Moxostoma valenciennesi) (this study), and smallmouth bass (Micropterus dolomieu) (Johnson et al., 2002; Seefelt and Gillingham, 2006b).
Information is available on the plasma glucose changes during starvation in the Atlantic cod, Gadus morhua L., the European eel, Anguilla anguilla (Larsson and Lewander, 1973), the pike,
Esox lucius (Ince and Thorpe, 1976), the toadfish, Opsanus tau (Tashima and Cahill, 1968), the goldfish, Carassius auratus (Chavin and Young, 1970), and the American eel, Anguilla rostrata (Moon, 1983).
Thermal behaviour of bone apatite of Recent pike (
Esox lucius L.).
Sex determination techniques by using external urogenital morphology have been developed for some of the mesothermal (coolwater) teleosts, including members of the ecosid family such as northern pikes
Esox lucius and muskellunge E.
Investigation of genetic diversity by microsatellite have been described within genes of a variety of fish species, including Caspian Sea Cyprinus carpio [29], Catla catla [1],
Esox lucius [12], Oncorhynchus masou [11] and Caspian Sea Salmo trutta [27].
Since at least the 1970s, there are records of Walleye (Sander vitreus), Tiger Musky (
Esox lucius x Esox masquinongy), Channel Catfish (Ictalurus punctatus), Northern Pike (
Esox lucius), and Smallmouth Bass (Micropterus dolomieu) being introduced into the lake (Tetra Tech 2002; Robertson 2006).
Pelican Lake contains northern pike (
Esox lucius) and largemouth bass (Micropterus salmoides), top-level piscivores, while Marsh Lake contains no predatory fish species.
Species present downstream but absent upstream included several sunfish (Lepomis spp.), Northern Pike (
Esox lucius) and Yellow perch (Perca flavescens).
Lammens (2001) noted that eutrophication in most European countries has caused a change of fish community from pike
Esox lucius L.
