A few massive catfish:
Silure catfish:
Size: In Russia "Ssum" is frequently caught at 600lb+ by trawlers. In Germany, France and Spain they are caught at over 100 lb with a 100lb cat usually attaining over 6 feet in length. However, in England the record catfish currently stands at 57lb 4oz. Through a study of bones it is thought that a maximum size for this species is around 1,000lb and such specimens are thought to live in some of the big Russian lakes where the commercial trawling vessels cannot fish; the local anglers use baby pigs for bait.( considerd to be the worlds largest fish) but i think that gigas thing grows longer i dunno).
Meekon river cat:
Measuring up to ten feet (three meters) in length and weighing up to 660 pounds (300 kilograms), the critically endangered Mekong giant catfish is one of the largest freshwater fish in the world.
