Introduction Results

Odisha coast is known to harbour around 605 Taxonomy fish species under 138 families and 27 orders'. The Order- Perciforrnes family Haemulidae includes 5 species viz., Plectorhinchus nigrus (Cuvier), Pomadasys argenteus Family- Heamulidae (Forsskal), P. argyeus (Valenciennes), P. kaakan (Cuvier), P. maculatum (Blotch)! in Odisha coast. The Type- Diagramma pictum (Thunberg, 1792) present record of the species Diagramma pictum Diagnosis: The body of the fish is oblong, laterally (Thunberg, 1792) belonging to the Family compressed. Total length of the fish is 16.52 em, Heamulidae is the first record to the Odisha coast. Standard Length (SL) is 13.35 cm and the Head Materials and Methods Length (HL) is 3.9 em, respectively.
