The Mozambique Current is where the big fish live, and you can get out there and pit your skills against them on a fishing charter trip from St Lucia in northern KwaZulu-Natal. Please just remember that big fish are top predators, and permanently removing top predators from an ecosystem can cause serious ecological imbalance. So, unless you catch something that can fit on the braai,  put the big guys back. St Lucia is situated in Maputaland, at the edge of the iSimangaliso Wetland Park.
