The present study investigates the effects of different feeding regimes with rotifers ( Brachionus plicatilis ) and Artemia salina on gene expression digestive enzymes in pikeperch Sander lucioperca larvae at 17 days post-hatch (DPH) over a period 13 days. Five experimental protocols were performed four replicates. At 4 DPH, (total length= 5.62 ± 0.03 mm, body weight = 0.66 0.16 mg) divided int...
In addition to ecological factors, evolutionary processes can determine the invasion success of a species. In particular, genetic admixture has the potential to induce rapid evolutionary change, which can result from natural or human-assisted secondary contact between differentiated populations. We studied the recent range expansion of zander in Germany focusing on the interplay between invasio...
This study was conducted in order to investigate genetic diversity and population structure of pike-perch in the Northern part of Iran. For this purpose, 207 adult pike-perches from four regions of the Caspian Sea watershed (Talesh Coasts, Anzali Wetland, Chaboksar Coasts and Aras Dam) were collected. DNA was extracted and by using 15 pairs of microsatellite primers, Polymerase Chain Reaction (...
The objective of this study was to assess the bioaccumulation of heavy metals (Cd, Pb, Cr and Fe) in the muscles of five fish species (Sander lucioperca, Liza auratus, Alosa caspia, Cyprinus carpio and Liza saliens) from Gorgan Bay in the south-eastern Caspian Sea, in order to determine the value daily intake of heavy metals by consumption of fish and human health risk assessment. The concentra...
