Human pressure: In the 1940s when shark fishery was at its peak the night shark was exploited by Cuban fisheries due to its high vitamin A content in its liver oil. There was a high mortality in the 1970s as bycatch due to swordfish and tuna fishery thus numbers have declined. Stated as protected in the US since 1997, although they continue to be caught as bycatch as the fish share the same habitat.
