Wow what cracking catches! 9 out of 10 piraiba are they all filamentous or could they be capa's? Just wondering why we get so many capa compared to fila's

They keep their golden/silver sheen with age regardless of size. That picture is from Andree's Expeditions and the fish was caught in 2015 in Suriname on the Coppenam River. I fished that same river with them last year and caught a 1.67M that was the largest the locals had ever seen and would have crushed the current IGFA record had I been on lighter line with official scales. The pictures don't do the golden color justice it was a lot more pronounced in person. That said I haven't seen any captive specimens with as much gold almost all are silver sheen which likely has to due with muddy water colorations and diet in the native range. I'll try to find the other pic of a big one from the 2nd trip in 2016 I've got it at home I think. For whatever it's worth out of the 30 fish we landed that week only 1 Dourada, all the rest were Piraiba. Similar catch rates on the other trips.

I noticed similar yellow/gold in native fish that didn't exist in captive specimens with Ageneiosus Magoi from Columbia. The wild pics all had a lot of yellow and captive had almost none.

Exactly, the color change is significant when boating/releasing these fish from stress and photos can frequently wash out the color even more given the harsh tropical lighting mid day. My fish had substantial sheen the full length of it's body with more golden towards the mid and tail section and more silver on the head.

That's quite a fish. Impressive color that one. Makes me wanna grow one out just to see if it has the same color.

Looks like the real mccoy. Filamentosum.

Wow. Speechless. You are the man! Is this the dourada that would have broke the record or the prior one? I couldn't tell from the post.

I have never taken a closer look to try to specifically ID the Piraiba we caught as capa or fila honestly. It is most likely collection location that is behind the influx of capa vs fila as I'd assume most come from Brazilian importers and with the price point being significantly higher for fila's it would align with collection/export difficulty. Sorry to derail.

The one in the pics I posted is the one that would have broke the record. The current rod and reel record is 54" that weighed 85lb 9oz mine was 65.7" and est 115-120lbs. I'm 6'2 and 210lbs for comparison.

Super slow growing fish and not very aggressive eaters at all. Need to be kept with fish that exhibit the same character. Anything that eats aggressively will out compete it for food and eventually will create inconveniences for the fish.

Holy cow that's amazing! Nice catch man!
