“…The results indicated the possible existence of three genetically discrete YFT populations (western, south eastern, and all remaining sites) in the North-western Indian Ocean around Sri Lanka (Dammannagoda et al, 2008). Furthermore, sequence analysis of mtDNA D-loop region in North Indian Ocean along the waters of India has indicated the presence of three genetically different stocks (one around northwest coast, a second around southwest coast, and a third around rest of Indian Seas) of YFT (Kunal et al, 2013). Thus, these studies have strengthened the idea about presence of more than one genetic stock of YFT in Indian Ocean.…”

“…Sammons (1971, 1973) reported the homogeneity at the superoxide dismutase locus among samples from the Western and Eastern Atlantic Ocean. After surveying a total of 23 enzymes, Thompson and Kunal et al (2013) Contin (1980) detected polymorphism for two more loci (ACP*, G6PDH*), but failed to assign a genetic basis to the observed phenotypes. Pujolar et al (2003) detected the moderate level of genetic heterogeneity with only two highly polymorphic loci in Atlantic bluefin tuna, but these differences disappeared when using multilocus estimates.…”

“…In the 1990s and early 2000s, RFLP analyses of mtDNA became the method of choice for many population studies (Alvarado Bremer et al, 1998;Ravago-Gotanco et al, 2004;Quinta et al, 2004;Hoolihan et al, 2006;Menezes et al, 2006). However, in recent times, sequencing of mtDNA has become the most widely used technique for studies of population structure of tuna (Dammannagoda et al, 2008;Chiang et al, 2008;Wu et al, 2009;Kumar et al, 2012b, d;Menezes et al, 2012;Kunal et al, 2013). Because mtDNA sequencing provides a large amount of information on sequence composition and mutations present in a particular mtDNA fragment compared with the RFLP approach which provides limited information on specific mutations only.…”

In this study, we have reviewed the population genetic structure of eleven tuna species (albacore, bigeye, yellowfin, Pacific bluefin, Atlantic bluefin, southern bluefin, blackfin, longtail, skipjack, frigate, and little tuna) with a global perspective. Based on the studies using molecular markers, there are 50 genetically distinct populations of tuna species worldwide (12 albacore, 4 bigeye, 9 yellowfin, 4 bluefin, 2 blackfin, 2 longtail, 12 skipjack, 2 little tuna, and 3 frigate tuna). It is evident that some tunas (albacore, bigeye, yellowfin, bluefin, and skipjack) have got more attention of researchers than the others (longtail tuna, blackfin tuna, little tuna, and frigate tuna), possibly because of their higher commercial importance. So, the larger number of studies on some species of tuna might be the reason for the higher number of population structure observed. Also, relying on the results of a single molecular marker, which were used in some studies, may produce misleading conclusions. Therefore, complementary sets of markers should be used in assessing population structure. Still, the number of to date revealed genetically distinct populations in some tunas species (albacore, yellowfin, and skipjack) is higher than number of stocks managed by authorities grouped in tuna regional fisheries management organizations. It might be a signal for reevaluation of fishery management of such tunas.

“…Genetic markers, mitochondrial DNA fragment covering the 5' variable portion of the control region (D-loop) and cytochrome oxidase 1 (CO1), are considered as efficient and powerful tool for identification of fish species including tunas, hence these were used in this study (Ward et al 2005;Paine et al 2007;Kunal et al 2013). The~600 bp fragment of D-loop was amplified using the primers CB3R420 (5'-CCCCCTAAC TCCCAAAGCTAGG-3') and 12Sar430 (GCCTGCG GGGCTTTCTAGGGCC-3') (Santos et al 2010).…”

“…In this study, we use PCR-RFLP (polymerase chain reactionrestriction fragment length polymorphism) analysis of mtDNA D-loop markers to investigate the genetic divergence between Auxis thazard and A. rochei for the first time. Selection of the mtDNA D-loop for analysis was based on its documented hypervariability in many fish species (Menezes et al, 2012;Kumar et al, 2012a, Kunal et al, 2013 and the availability of specific primers for amplification of this region (Menezes et al, 2006). (Asahida et al, 1996).…”

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 conducted to estimate the degree of genetic divergence between two species based on PCR-RFLP analysis of D-loop region (500 bp) of mitochondrial DNA in 100 individuals collected from Tuticorin (India). High level of genetic divergence (9.26%) was observed between A. thazard and A. rochei. Estimates of molecular diversity indices were higher in A. rochei (π = 3.8808; hd = 0.9641) compared to A. thazard (π = 2.2514; hd = 0.8441). Based on demographic parameters, population expansion of A. thazard estimated to begin about 67,167 years before present while of founding of A. rochei took place about 114,747 years before present in Indian Ocean. Thus, we conclude that A. rochei represents the ancestral species of genus Auxis.
