"Southern Meagre" says the FAO species book on Angolan fisheries: 200cm max published weight 71 kgs at an age of 30 years... ( only problem: Fishbase says it's endemic to the indopacific! Argirosomus hololepidotus ) . Who cares: F.A.O. says it's that fish and it's of commercial importance in Angola:
I revise my previous guess: if Albert ( 1,97 m ) holds a 32,2kgs in his hands here... Manito will be stemming a fish well 25% heavier, make that good 45 kgs.
