A third more fish are being caught globally than is being reported, a new study says. The new estimate, calculated by Sea Around Us, a research organisation at British Columbia University, places the annual global catch at 109milliontons, higher than the 77 milliontons that 200 countries and territories reported in 2010.This was because catch information was not collected correctly and difficult to track sectors like artisanal, subsistence and illegal fishing and discarded fish were not counted properly.South Africa is not exempt from under-reporting catch.John Duncan, WWF marine programme senior manager, said there was no effective monitoring of recreational fishing in South Africa. And poaching of abalone and rock lobster was also skewing tallies."The problem is that if you have no accurate fisheries data, then you are flying blind," Duncan said.Another concern is corruption, said Aksel Sundström, who is affiliated to the Quality of Government Institute at the Gothenburg University in Sweden.He said poaching of abalone and rock lobster brings in big money."Those who engage in poaching these resources are very poor. Some middlemen are from criminal gangs and make big money on this trade."..
