The geographic isolation impact on evolution of some morpho-physiological features in the brown trout (Salmo trutta fario Linnaeus)
Journal Title: Aquaculture, Aquarium, Conservation & Legislation - International Journal of the Bioflux Society - Year 2009, Vol 2, Issue 1
Abstract
The researches made by our team have in view the bio-morphometric study of some brown trout populations. We aimed, on the one hand, to see the geographic and reproductive isolation impact and, on the other hand to highlight the environmental factors’ influence on morphological features in this species. The researches have in view three aquatic basins, known as sanctuaries of the brown trout, respectively Someş, Criş and Arieş. For the morphometric study were taken in calculus 14 body dimensions, which allow to analyze on scientific basis the intra-specific variability degree, to which we add also the estimation of some meristic features (number of red or black spots). All data were statistically processed using modern methods thereby the interpretation errors to be more reduced. The results are presented in tables included in our paper.
