Effect of feed restriction on fatty acid profile, body composition and selected blood parameters of intensive reared pike (Esox lucius)

چکیده
This study investigated the effects of a six-week starvation period on fatty acid profile, body composition and blood parameters intensively reared pike (Esox lucius). 150 were stocked in an experimental recirculating aquaculture system (RAS) feed was completely withdrawn. Body composition, (serum protein, albumin, triacylglycerol, cholesterol concentration Lactate dehidrigenase alkaline phosphatase activity) measured somatic indices calculated. A significant decline bodyweight, crude fat content accompanied by decrease triacylglycerol content. The relative proportion saturated acids fillet decreased, while polyunsaturated increased. There also increase average chain length unsaturation index found flesh.

15 صفحه اولImpact of pulp and paper mill effluent on egg hatchability of pike (Esox lucius L.).
Toxicants affect reproduction often at concentrations well below lethal levels. Also, the acidification of fresh waters has been shown to cause extinction of teleost fish populations usually through a failure of recruitment from younger generations. Both field and laboratory studies have documented that the greatest susceptibility to low pH occurs in the early developmental stages (e.g. Lee et ...

15 صفحه اولMercury 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 کاملGenetic structure of pike (Esox lucius) reveals a complex and previously unrecognized colonization history of Ireland
AIM We investigated genetic variation of Irish pike populations and their relationship with European outgroups, in order to elucidate the origin of this species to the island, which is largely assumed to have occurred as a human-mediated introduction over the past few hundred years. We aimed thereby to provide new insights into population structure to improve fisheries and biodiversity manageme...
