I believe Kingklip is an eel rather than fish. Stand corrected though.

Tomato bredie, fresh seafood, especially lobster, crayfish, prawns, kabeljou, kingklip, smoked snoek.

It's an incorrect spelling of the kingklip fish, an eel-like fish found in the Southern Hemisphere off Argentina, Chile, Australia, New Zealand, and South Africa.

Kingklip seems to be a kind of eel, and traditionally, eels are not considered kosher. To be kosher, a fish must have fins and scales, and the scales of most eels do not quite meet the traditioinal Jewish definition of a scale because they are embedded in the skin instead of loose where they can be scraped from the skin. However, there are Orthodox Jews who argue that it should be kosher because its scales appear to be just over the line into acceptability. In sum, it's a borderline case, and the traditional Jewish approach to such borderline cases is to "just say no."
