Cytochrome Oxidase I (COI) sequence conservation and variation patterns in the yellowfin and longtail tunas
Kunal, S.P.; GirishKumar (Inderscience, 2013)Tunas are commercially important fishery worldwide. There are at least 13 species of tuna belonging to three genera, out of which genus Thunnus has maximum eight species. On the basis of their availability, they can be ... -
Genetic divergence between Auxis thazard and A. rochei based on PCR-RFLP analysis of mtDNA D-loop region
GirishKumar; Kunal, S.P.; Menezes, R.M.; Kocour, M. (Central Fisheries Research Institute (CFRI) Trabzon, 2014)Tunas of genus Auxis are commercially and ecologically important fish of family Scombridae. There is currently no information concerning the genetic divergence between A. thazard and A. rochei. Therefore, a study was ... -
Genetic homogeneity in longtail tuna Thunnus tonggol (Bleeker, 1851) from the northwest coast of India inferred from direct sequencing analysis of the mitochondrial DNA D-loop region
Kunal, S.P.; GirishKumar; Menezes, M.R.; Meena, R.M. (Taylor & Francis, 2014)Longtail tuna Thunnus tonggol is a neritic species of the family Scombridae, having a confined coastal distribution to tropical and temperate waters of the Indo-Pacific region In the present study, the population structure ... -
Genetic stock structure of frigate tuna (Auxis thazard) along Indian coast based on PCR-RFLP analyses of mtDNA D-Loop region
GirishKumar; Kunal, S.P.; Menezes, M.R. (Central Fisheries Research Institute (CFRI) , Turkey, 2012)Frigate tuna (Auxis thazard) is an epipelagic, neritic as well as oceanic species. In present study, genetic variation was surveyed using PCR-RFLP of mitochondrial DNA D-loop region to test for the presence of stock structure ... -
Genetic variation in Yellowfin Tuna Thunnus albacares (Bonnaterre, 1788) along Indian coast using PCR-RFLP analysis of mitochondrial DNA D–Loop region
Kunal, S.P.; GirishKumar; Menezes, M.R. (IJSR, 2014)Yellowfin tuna Thunnus albacares is an epipelagic, oceanic species of family Scombridae, found in tropical and subtropical region of the Pacific, Atlantic and the Indian Ocean. It is a commercially important fish species. ... -
Low genetic variation suggest single stock of Kawakawa Euthynnus affinis (Cantor, 1849) along the Indian coast
GirishKumar; Kunal, S.P.; Menezes, M.R. (CFRI publisher, 2012)Kawakawa Euthynnus affinis is an epipelagic migratory tuna species, widely distributed in the tropical and subtropical waters of the Indo-Pacific region. It constitutes the largest tuna fishery in Indian waters. In present ... -
Mitochondrial DNA analysis reveals three stocks of yellowfin tuna Thunnus albacares (Bonnaterre, 1788) in Indian waters
Kunal, S.P.; GirishKumar; Menezes, M.R.; Meena, R.M. (Springer, 2013)Yellowfin tuna (Thunnus albacares) is an epipelagic, oceanic species of family Scombridae found in tropical and subtropical region of Pacific, Indian and Atlantic Ocean. It is commercially important fish and accounts for ... -
Mitochondrial DNA variation and phylogenetic relationships among five tuna species based on sequencing of D-loop region
GirishKumar; Kocour, M.; Kunal, S.P. (Taylor & Francis, 2016)In order to assess the DNA sequence variation and phylogenetic relationship among five tuna species (Auxis thazard, Euthynnus affinis, Katsuwonus pelamis, Thunnus tonggol, and T. albacares) out of all four tuna genera, ... -

GirishKumar; Kunal, S.P.; Menezes, M.R.; Meena, R. (Springer, 2012)Kawakawa Euthynnus affinis is an epipelagic migratory tuna species, widely distributed in the tropical and subtropical waters of the Indo-Pacific region. Kawakawa constitutes the largest tuna fishery in the Indian waters. ... -
Three genetic stocks of frigate tuna Auxis thazard thazard (Lacepede, 1800) along the Indian coast revealed from sequence analyses of mitochondrial DNA D-loop region
GirishKumar; Kunal, S.P.; Menezes, M.R.; Meena, R.M. (Taylor & Francis, 2012)Frigate tuna Auxis thazard thazard is a cosmopolitan species and one of the smallest members of the tribe Thunnini (the true tunas), and currently managed as a single stock. Genetic variation of this species was surveyed ...
