Morphological Aspects on Heart and Main Blood Vessels of Black Sea Turbot (Psetta maxima) – Corrosion Cast and Morphological Studies

The turbot (Psetta maxima) is one the most valuable and economically important species for the Black Sea countries.The purpose of the current study was to investigate the cardiovascular system of this species with both corrosion cast and routine histology methods on 12 sacrificed turbots (6 males and 6 females) obtained from a hauls.After that fish were sacrificed and the blood vessels were filled through the heart with self-curing castable resin Duracryl Plus U. Apart, materials from some parts of vasculary system for histology examination were taken and fixed in 10% neutral formalin solution.Based on the corrosion cast and histological techniques we described luminal structure and size of the aorta in turbot.
