Ricerche Elettroforetiche Sulla Variabilita Genetica Di Anguilla Anguilla

Abstract
This note refers to a preliminary research intended to verify the possible presence of different populations of eels (Anguilla anguilla L.) in the Mediterranean sea. Eel tissue samples have been analyzed by means of electrophoresis on starch gel. Five enzyme systems present in tissue extracts from glass-eels (elvers) have been studies: MDH I and II, PHI I and II, SHD; four of which are variable and useful as genetic markers. The genetic and molecular interpretations of the complex electrophoretic patterns and the gene frequencies observed on three different samples of elvers from the Tyrrhenian sea are also reported.
