This Grouper was produced by fertilizing the eggs of the Tiger Grouper (Epinephelus fuscoguttatus) with the sperm of the Giant Grouper (Epinephelus lanceolatus) through in-vitro fertilization (IVF) technique. The first hybrid Grouper was cross-bred by researchers at the University of Malaysia Sabah (UMS), in collaboration with researchers from the Borneo Marine Research Institute of UMS, The Fisheries Development Authority of Malaysia (LKIM) and Kinki University of Japan, under the leadership  of Prof. Dr Shigeharu Senoo of UMS.
