In five species of fish from the Family Sciaenidae, collected from marine, brackish and fresh-water environments, the following parameters were studied: haemoglobin concentration, haematocrit, number of red blood cells, mean corpuscular volume, mean corpuscular haemoglobin, mean corpuscular haemoglobin concentration, blood pH, oxygen affinity of blood and stripped haemolysate, Root effect, the number of haemoglobins separated by polyacrilamide electrophoresis, iron concentration and osmotic pressure of the serum. Plagioscion squamosissimus, the only freshwater species studied, clearly separated from the other four species; it exhibited the highest haemoglobin number, haemotocrit, number erythrocytes, of oxygen affinity of the haemolysate, and the lowest oxygen affinity of the blood, iron concentration, pH and osmotic pressure.
