STUDIES ON SOME MORPHOLOGICAL CHARACTERS IN BIGHEAD CARP FRY

Abstract

The present paper investigates some morphological characters (total length, standard bodily length, head length, maxim height and bodily circumference) in representatives of bighead carp (Aristichthys nobilis) occurring in their first growing summer. Biometric analyses were performed on 100 individuals, in the end the morphological characters under investigations being statistically processed. Explanation of the experimental results evidences low values of the standard error of the mean, which is indicative of a grouping of all external bodily variables under investigation close to the average value.
