mana moana
1. (noun) authority over the sea and lakes - although this is a modern term, the concept of authority over lakes and parts of the sea (mana o te moana) is traditional. According to Māori custom, land rights extended as well to adjacent sea or lakes with fixed boundaries for inshore and deep-sea fishing and the gathering of seafood.
