 Similarly, the proportion of night sharks in the shark catch of the southeastern U.S. pelagic longline fishery fell from 26.1% from 1981 to 1983 to 0.3–3.3% in 1993 and 1994; a comparable decline was observed in catches by South Florida marlin tournaments since the 1970s.Currently, the intense Brazilian targeted fishery is of particular concern, although fishing pressure on the night shark may be relaxing as the fishery is beginning to shift towards swordfish and bigeye tuna ("Thunnus obesus").No fishery information on the night shark is available for the eastern Atlantic, leading to an IUCN assessment of data deficient for that region.
