Environmental governance aims to develop and understand the lessons, achievements challenges of planning at both local global levels. In particular, integrated river management is key sustainable development ecosystems, collaborative inclusive approach among stakeholders supports decision-making process. The objective this study was assess current model for recreational fisheries in Olo River R...

Mitotic gynogenesis results in the production of fully homozygous individuals in a single generation. Since inbred fish were found to exhibit an increased frequency of body deformations that may affect their survival, the main focus of this research was to evaluate the ratio of individuals with spinal deformities among gynogenetic doubled haploids (DHs) brown trout as compared to nonmanipulated...

The course of a VHS (viral haemorrhagic septicaemia) infection in brown trout Salmo trutta fario L. in a stream was followed for 4 yr using anti-VHS virus antibodies a s the indication of infection. Trout were caught by electrofishing and the presence of anti-VHS virus antibody in the serum was determined by counter-current immunoelectrophoresis. There were fluctuations in the prevalence of ant...

The detection of low levels of pharmaceuticals in aquatic environments has lately raised concerns regarding possible adverse effects of these highly active substances on aquatic organisms. The non-steroidal anti-inflammatory drug diclofenac (DCF) is one of the pharmaceutical substances regularly detected in surface waters and has lately been demonstrated to elicit adverse effects in salmonid sp...

We characterized the insulin receptors in skeletal muscle from several fish species with different nutritional preferences: brown trout (Salmo trutta fario), gilthead sea bream (Sparus aurata), tilapia (Tilapia mossambica), and carp (Cyprinus carpio), semipurified by affinity chromatography (wheat germ agglutinin-agarose). Total specific binding and number of receptors per unit weight of piscin...
