And that link is supposed to prove what exactly?
I'm not arguing the fact that there are variations, color morphs, etc among the various red arowana bred at various farms, I am referring only to
wild specimens.
Can you provide any links showing
wild caught reds, showing these various different traits that you keep referring to? I think not.
Once again, these so called "different" lakes are all part of the same watershed, they are all interconnected, and during the dry season they all flow back into the head waters of the Kapuas River. These are not isolated bodies of water where somehow some red aros have over the years magically transformed to have different body shapes, caudal fin shape, longer pectoral fins, and different shaped heads.
During a lengthy or very dry, dry season, they pretty much dry up, which is why they are referred to as
seasonal lakes. No different than what one would find in the Amazon. In some years those massive flooded areas end up being nothing more than a small pocket of water, where fisherman can easily cherry pick each & every fish out of the water. This is precisely why the fisherman in this area fish heavily during the dry season.
What part of this do you not understand?
In Lake Santarum, during the
rainy season the depth of the lake may reach 6-8 metres, flooding the surrounding areas and forest. During the
dry season, when the level of the Kapuas river gradually drops, water from Lake Sentarum flows into Kapuas to restore the water deficit and keep the water level of the river relatively stable.
Eventually, when the dry season reaches its climax, Lake Sentarum and the surrounding areas become a vast stretch of dry land, the fish from the lake inhabiting small, scattered ponds.
To date there have been no distinctions observed by researchers between the various red aros in the wild. Beyond internet folklore, there is no proof whatsoever that any such fish exist.
What you & others are seeing are differences between
farm bred fish, where various physical traits can easily be bred in or out of the fish.
Selective breeding has been used for thousands of years, aro breeders certainly didn't invent line breeding, or cross breeding.
