Evaluation of the rivers Vilnia and Siesartis ecotoxicological state based on morphological indexes of juvenile Atlantic salmon (Salmo salar L.)
Objective of the study – to evaluate ecotoxicological state of two probably differently polluted salmon rivers: the Vilnia and Siesartis based on Atlantic salmon (Salmo salar L.) juvenile’s morphological indexes. Statistical analysis of estimated fish morphometric parameters and morphological indexe...
