First Report Confirming the Occurrence of Jumping Halfbeak Hemiramphus archipelagicus Collette and Parin 1978 (Beloniformes: Hemiramphidae) from the Western Bay of Bengal

The Jumping halfbeak, Hemiramphus archipelagicus Collette and Parin 1978, has been previously reported from the west coast of India (Arabian Sea). During a taxonomic study on Hemiramphidae, eight specimens of H. archipelagicus, collected from the coastal water of Odisha, east coast of India, were examined. The species is characterized by 13–14 dorsal-fin rays, 9–12 anal-fin rays, 11–12 pectoral-fin rays, 6 pelvic-fin rays, 25–28 gillrakers on first gill arch and 36–41 pre-dorsal scales, body width less than the depth (62.1–62.3% in body depth), pectoral-fin short (17.2–18.4% in SL) not reaching anterior margin of nasal pit when folded forward, dorsal fin without well-developed anterior lobe and absence of vertical bars on the sides of body. This is the first report confirming the occurrence of H. archipelagicus from the east coast of India (western Bay of Bengal) suggesting that this species is widely distributed throughout the Indian coast

Taxonomic study of flatheads (Family: Platycephalidae) occurring along the West coast of India

1023-1028A total of thirty-one morphometric and meristic characters were measured, counted and compared among the species along with their respective proportions, like standard length and head length. Among ten meristic characters, six did not show any difference. However, four characters viz. number of gillrakers, black spot on 1st dorsal fin, increasing size of backwardly directed lateral line spines towards posterior end and preopercular spine revealed variations. The proportional measurements with their head length (HL) viz. snout length: head length (SnL: HL, Inter orbital width: head length (IOL: HL), and maximum eye diameter: head length (MED: HL) also revealed significant difference among the species

A report on anomalies in pelvic fin and pectoral filament of two species of genus <em>Setipinna </em>(Swainson, 1839) from east coast of India

1893-1898Present study consists the instances of anomalies in two species of genus Setipinna i.e. accessory pectoral filament in S. phasa, (Hamilton, 1822) and absence of pelvic fin in the S. taty (Valenciennes, 1848), collected from east coasts of India. Comparison of twenty seven morphometric measurements and twelve meristic characters of the abnormal with normal specimens confirmed abnormality. Furthermore, genetic divergence value of mitochondrial COI and 16S rRNA confirmed that both normal and abnormal specimens belong to the respective species. These abnormalities might have occurred in early stages of development. Abnormalities have affected only morphological aspects and not growth of the fish
