Molecular characterization of partial gonadotropin subunits in Pangasianodon hypophthalmus (Sauvage, 1878)

Pangasius hypophthalmus or Patin Siam is a fast-growing cultured catfish in the world and predominantly established for farming in Southeast Asian countries including Malaysia. In 2015, Department of Fisheries Malaysia reported the aquaculture production of pangasiid in Malaysia was 13,901.77 tonnes...
