The South African trawl fishery for hake is certified by the Marine Stewardship Council, the world’s leading certification and eco labelling programme for sustainable, wild-caught seafood.

Constitution

The SADSTIA Constitution sets out the fundamental principles according to which the Association is governed. SADSTIA’s first constitution was adopted on 24 March 1974 and an updated constitution was adopted on 12 September 2002. This was in recognition of the fact that circumstances in South Africa and the deep-sea trawling industry changed considerably in the intervening years, with membership of the Association being opened to a much larger number of vessel operators.
