I'm hoping one of our asian experts can answer a few questions for me. I know that the asian and the jardini are the same species (Scleropages), just different specific animals, so theoretically, it should be possible to cross them?

1. has anyone ever atempted to cross breed a jardini with an asian?
2. would the hybrid still be illegal in the US?
3. would the jardini gene be the dominant traits, or would the formosus?
4. is anyone artificially inseminating arowana?

thanks.
 
Nope they are not the same species bro...
Asians = Scleropages formosus
Australians = Scleropages jardini
and they cant breed, but if science wud found a way
that wud be cool! Although Asian X silver would be the bomb! :eek:
 
Thanks. I don't want to get into an argument about whether it's possible or not. I just want to know if anyone has tried.

Species is the first name (Scleropages) and the second name is the subspecies (formosus, jardini, leichardti). Seperate species cannot interbreed with some exception. Subspecies, however, and especially in the fish world do interbreed.

See: http://www.answers.com/topic/subspecies

The question is whether the jardini and formosus will breed. That's why they're seperate subspecies, ie. from different continents, but the same species.
 
It's definitely possible to force a hybrid of these 2 species. You just need to make the economics of such an undertaking feasable for investors to be willing to give it a try. There are hybrid stripers (wipers), hybrid sunfish, hybrid trout, etc. Why? Because there's an investment return from sportfishing stocking sales in the hybrids. There are not enough Monster fishkeepers to make multi-million dollar genetics research economically feasable for a hybrid of these species. The big money sales are already in place on the non-hybrid S. formosus without the added expense on decoding the DNA from the species to force hybridization. Selective pairing is the method used now. It costs nothing. It would have to be proven that a hybrid species could pull additional dollars in investment returns before such an expensive research undertaking would draw investors.

but naturally its impossible right?
 
I won't say it's impossible. I'll say it's highly unlikely. Each species has it's own homone-based pheramones, pre-spawning cues, and egg-mytosis hormone/gene recognition chemistries.

My bad. I thought Scleropages was the species, and jardini etc. was the subspecies. I just saw that in 2003 they were seperated into different species. So someone must have attempted to interbreed them.

Actually, the two fish were differentiated into separate species because they used to be thought of as the same species with regional physiological differences. Much the same way may other fish are being separated out as the science advances. (ie: Wallago biocellatus being removed from the genus Wallago and placed into the genus Ompok)
