With the improvements in next generation sequencing technologies in the past few years, many genome projects of aquaculture fishes have been reported, including Atlantic salmon (Salmo salar) , Atlantic cod (Gadus morhua) , rainbow trout (Oncorhynchus mykiss) , Japanese flounder (Paralichthys olivaceus) , half-smooth tongue sole (Cynoglossus semilaevis) , platyfish
(Xiphophorus maculatus) , common carp (Cyprinus carpio) , and channel catfish (Ictalurus punctatus) , and molecular markers of the shared genomic loci among individuals have been obtained for genotype-phenotype linkage analysis.

In teleost, we identified either single copy of MGST2 gene (such as common carp, zebrafish and platyfish
, etc) or absent (such as stickleback, medaka and pufferfish, etc), which suggested that MGST2 gene was lost in some teleost genomes completely, but still retained one copy in Cyprinids such as carp and zebrafish.

The variable platyfish
(Xiphophorus variatus) is endemic to the Gulf of Mexico drainages of southern Tamaulipas to northern Veracruz, Mexico (Miller et al., 2005).

In the case of teleosts, it was reported in the 1960s that the erytnro-phores of Xiphophorine fish, such as the swordtail (Xiphopho-rus helleri) and platyfish
Fish species examined in this study were: "southern platyfish
" Xiphophorus maculatus (n = 35), "goldfish" Carassius auratus (n = 31), "guppy" Poecilia reticulata (n = 20), "sailfin molly" Poecilia latipinna (n = 6), "beta" Betta splendens (n = 2) and "spotted headstander" Chilodus punctatus (n = 1).
Other close relatives, swordtails and platyfish
of the genus Xiphophorus, however, are known to be mostly omnivorous with an emphasis on herbivory (e.g., Maddern et al.
