Description Samples of fishes of the family Balistidae were collecfed regularly from landings
of hook and line and trawl at Tuticorin and Kanyakumari along southeast coast of
India; Vizhinjam and Colachel along southwest coast oflndia during August 1998
to October 2000. Specimens of a few species were collected from trawl, trap,
spear, gill net and hook and line landings of Mumbai, Veraval, Chennai,
Mandapam and Kelakarai and Minicoy Island (Lakshadweep) were also analysed
for this work. Specimens in the collections of Zoological Survey of India (ZSI),
Kolkatta and those in the reference collection Museum of the Central Marine
Fisheries Research Institute (CMFRI) at Cochin and Mandapam were also
examined.
2. The morphological characters like teeth, nasal apertures, gi ll rakers were studied.
3. Based on the shape of the first and second teeth of the upper and lower jaw, fi ve
types have been identi fied.
4. The anterior nasal aperture has different shapes, which is species specific but the
posterior aperture is similar in all species. Based on the shape of the anterior nasal
aperture five types have been identified.
S. The outer most branchial arch possesses gill rakers. Based on its shape they are
divided into five types.
6. The pattern of arrangement of scales and its eternal morphology was studied.
7. Scales on body and caudal peduncle are diamond shaped, were as scales on cheek
are rhomboid, rectangular, square or triangular occurring in different
combinations. Scales on abdomen are rhomboid or rectangular or square with
round edges.
8. The arrangement of scales on body, abdomen and caudal peduncle were similar
between the species.
