Early development of the Amur sleeper (Perccottus glenii, Dybowski, 1877): a remarkable invasive species in Eurasia
To investigate the ontogeny of Perccottus glenii, embryonic, larval and juvenile development of P. glenii were examined under captive condition. The fertilized eggs with numerous oil droplets were orange-pink in color, prolate spherical in shape and had average length of 3.32±0.14 mm and width of 1.24±0.04 mm. From fertilization to hatching, the ontogenesis of the fish spent more than 200...

متن کاملReduction of cannibalism in pike (Esox lucius) fry by isolation of full-sib families.
After 50 days of pond culture fewer pike fingerlings (20 to 33 p. 100) were recovered from the mixing of two full-sib families than from isolated families. Growth and survival were influenced by the family effect. Environmental parameters, such as depth and extent of the banks, may also affect growth and survival. Our results indicated that isolating full-sib families and using small, shallow p...
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...
متن کاملMercury toxicity in livers of northern pike (Esox lucius) from Isle Royale, USA.
Many laboratory studies have documented that mercury can be toxic to fish, but it is largely unknown if mercury is toxic to fish in their natural environments. The objective of our study was to investigate the toxic effects of mercury on northern pike (Esox lucius) at Isle Royale, Michigan. In 124 northern pike from eight inland lakes, concentrations of total mercury in skin-on fillets ranged f...
