View Full Version : Jardini/Asian Hybrid?

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.

Scleropages is the Genus name. And, formosus and jardini are two of the species within that genus.

what he said ^
and its not possible

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?

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.

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.

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)

isnt' interbreeding what dictates species? If they are classified as seperate species, then it must be impossible to interbreed?

When it comes to nature, we must stop using the word 'impossible'. Nature will find a way to fill a niche even if it means inter-breeding. For the most part though, any interbreeding will be unsuccessful and extinction of a species within a given altered niche (climate change, geological alteration, etc.) will occur.

Nice. Thanks for clearing this up for me.

I dont think the outcome will look nice.. its probably just my imagination.

I agree I think the outcome would not be very appealing. I agree with the rest about the interbreeding as well although it would not be impossible. Also as pointed out it does not have market acceptance here in the east.

any more info on the legalization of aros in the US?

No. The species would have to be removed from listing, i.e., "delisted" similar to what's being proposed for the bald eagle, under the federal Endangered Species Act, which is unlikely without some sort of improvement in wild populations.

Sorry I didn't realise the question was directed at me. Like I said I was told my the fishery guys locally. If indeed there is anymore news, I will be sure to pass it along. It would be a great day for u guys at the states.

i would agree. with the right technique i think it might just be possible, lions and tigers and leopards all from the same genus have been recorded to have cross bred. saying its impossible is really thinking limitedly. what i would rather see though is a cross between a super red arowana and a giant south american silver arowana, though not the same genus its worth dreaming about :drool:

no one would do it as it wld ruin the already diluted formosus gene.
the outcome would be highly ugly hence no one has tried or wants to try.
Anyway... unless u want a very ugly hybrid i don't think you'd want a go.
