    On the use of diagnostic bones of brown trout, Salmo trutta m. fario, grayling, Thymallus thymallus and Carpathian sculpin, Cottus poecilopus in Eurasian otter, Lutra lutra diet analysis.

  • Original language description

    Bones were obtained from three fish species (Salmo trutta m. fario, Thymallus thymallus and Cottus poecilopus) for regression analysis. Bones used were chosen based upon frequency of occurrence in spraint samples and diagnostic value. Relationships between the length of diagnostic bones and fish length, fish length and weight, and standard length to total length, were assessed for the three fish species. Polynomial regression was deemed most suitable for the relationship between bone length and fish standard length, multiplicative between fish standard length and fish weight, and linear or polynomial for standard length against total length. All calculated regressions were highly significant and displayed high coefficients of determination, ranging between 93.9 and 99.8 %. The uses of the bones examined, and the equations produced, are discussed in the light of their future use in estimating prey numbers, length and biomass in otter diet analysis.
