In anticipation of my upcoming trip to Villahermosa (Tabasco state, Mexico), here is a great video put together by colleagues at the tropical gar aquaculture farm (Otot-Ibam) highlighting their gar production. Great shots/sequences of gar development and the culture process. I’ll be presenting at the 4th International Meeting on Lepisosteid Research in mid-June, and we’ll get to tour the farm as well as participate in workshops.

The gar were spawned in holding tanks as part of a research project studying methods of rearing the fish in captivity. Photo: Craig Gautreaux/LSU AgCenter

This is an example of a combination of unusual genetic conditions expressed in fishes and other organisms. Xanthochroism is a condition where all pigments other than yellow and orange are absent or minimally expressed. Melanism is an excess of dark pigmentation. This fish is a combination of the two conditions; it has previously been observed in gars, and the combination of colors seems to be most apparent during spawning season.
