What is the biggest FW fish?

ok that made me laugh lol

 

To me you would have to go by the fish with the most volume.

By length is a bad way IMO because it doesn't take into account the width.

Weight is a bad way IMO because the question was biggest fish, not heaviest.

Surface area doesn't work for me because fish are different shapes. Some shapes have more surface area while the fish is actually smaller and weighs less.

The easiest way to measure the volume of a fish would be to put it inside a container of water and see how much it raises the water level.

 

that actually seems like its the best way to do it.

but where will we get the water? i kids lol

 

:inquisitiSometimes I wonder why I even signed up to this forum......

Right now all we can really do is judge it by "look at how big that thing is" size. Just plain massiveness.

What about going out and cathing one of these bad boys?

 

They have a bunch of arapaima at the dallas world aquarium.. they're huge.

According to wikipedia some sturgeon can far exceed the size of a mekong catfish but both are some times part saltwater fish.. Wiki says the mekong catfish is widely recognized as the largest freshwater fish.
Mekong giant catfish - Wikipedia, the free encyclopedia

 

the problem with sturgeons, besides being saltwater too, is do they really reach that size anymore or are they just killed before that.

 

strangely i think im getting hungry looking at that fish.

and the answer is for the thought provoking conversation of course.

 

this fish was caught in fraser river.

it weighs 800 pounds , 11 feet long
estimated to be 120 years old.

 

You should also take into consideration what a "fish" is. I wouldn't think a stingray would be considered fish, but you may.

 

that arapaima looks pretty wild with the red on its scales. very cool
