One specimen of the shortfin neoscopelid Neoscopelus microchir Matsubara, 1943, has been recorded for first time on Porcupine Bank, southwestern Ireland, providing a new northern limit distribution eastern Atlantic. Morphometric and meristic parameters confirm taxonomic identification. However, DNA barcoding shows deficiencies in current taxonomy potential occurrence cryptic species. On this ba...

A total of 200 threadfin bream Nemipterus japonicus was collected from Chennai in the east coast and Kochi in the west coast during January to February 2013 and studied for their morphometric and meristic characters. In total, 21 characters were analyzed out of which 3 characters namely dorsal, ventral and anal fins were not considered since they were unaltered. The findings indicate that 91% o...

In a meristic, morphometric and distributional study of Neolissochilus from Peninsular Malaysia, Khaironizam et al. (2015) subsumed Lissochilus tweediei Herre in Herre & Myers 1937 and a taxon they called "Tor soro Bishop 1973" into the synonymy of N. soroides (Duncker 1904) based on data collected from museum specimens. However, "Bishop 1973" is not the correct author citation for Tor soro. In...

Among vertebrates, most of the fishes are unique for the lack of acrosome in their spermatozoa. The sperm enters the egg through micropyle of the egg. This has facilitated heterologous fertilization in many fishes and led to hybridization and polyploidization. Hybridization is performed both in the nature and domesticated fishes. Today, some of the hybrids have high growth rate than their paren...
