Soluble red muscle proteins from the lateral line of 15 Sparidae species were analysed by isoelectric focusing. Species‐specific patterns were found. The species‐specific protein fractions could be correlated with different metabolic activities and with different growth indexes. More protein fractions were identified for Pagellus acarne (Risso) and Diplodus annularis (L.) than for the other 13 species. This would appear to be related to growth index. The existence of red muscle with a greater number of protein bands than white muscle was confirmed in almost all species. The similarity coefficients have shown that closely related species have similar patterns and, thus, higher similarity coefficients. The derived dendrogram agrees with previous classifications based on morphological information.
