Anatomical, 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 کاملPrevalence and intensity of parasites in pike (Esox lucius) from Anzali Wetland and evaluation of their impacts on biometric characticties in host fish
Parasite communities of pike (Esox lucius L. 1758) were calculated in Anzali Wetland along with evaluating their impacts on biometric characticties of the fish host. A total of 4338 parasites from 11 diferent species were identified including: Ichthyophthirius mutifiliis (21.88%); Trichodina sp. (8.59%); Henneguya sp. (0.78%); Tetraonchus monenteron (60.94%); Diplostomum spathaceum (23.44%);...
متن کاملThe first record of Northern pike (Esox lucius Linnaeus) in the Zrebar Lake of Marivan, Kurdistan, Iran: A preliminary observation and assessment of morphology, diet, reproduction and invasive threat
The Zrebar Lake is a most important natural freshwater Lake ecosystem in the Kurdistan Province, west of Iran. Since Decembeer 2019, there has been reports of an unusual fish species sighting in the Zrebar Lake. This has led our efforts to set traps, capture and identify the species as Esox lucius Linnaeus. Consequently, we made further, field assessments and conducted biological study in the ...
متن کاملBehavioural and fitness consequences of direct and indirect non-lethal disturbances in a catch-and-release northern pike \(Esox lucius\) fishery
Key-words: angling, disturbance, fitness, telemetry, Esox lucius In a catch-and-release recreational fishery fish populations can be impacted by lethal and sub-lethal effects. In terms of sub-lethal effects anglers may directly (catch-and-release) and/or indirectly (angling-related disturbances, e.g. boating) influence the behaviour, growth and fitness of the fish. We quantified the long-term b...
متن کاملMercury Concentration in Muscle and Liver of Pike (Esox lucius) Collected from Anzali International Wetland, Iran
Background: Mercury (Hg) is a major environmental contaminant due to its global ubiquity, tendency to bioaccumulate, and toxicity in wildlife. Mercury accumulation in wetlands threatens critical breeding and foraging habitats of many fish and wildlife species. In this study, mercury concentrations were detected in different tissues of pike. Methods: To achieve these purposes, 58 pikes (Esox l...
