Threats

Aetomylaeus bovinus is facing various and numerous threats, from fisheries to habitat degradation. As it is a benthic and semi-pelagic feeder, it is bycaught by a large number of industrial and artisanal fishing gears, especially pelagic trawling, bottom trawling, trammel nets, gill nets and spearfishing. Little information is available concerning this species in Africa, however old literature refers to a discard of 900 tonnes per year of bull rays bycaught by shrimp trawlers on the West African coast in 1988 during their late juvenile and sub/adult phase.

In the Mediterranean Sea bull rays are considered critically endangered (Cr), the last step before extinction!

(A) The landed catch of chondrichthyans reported to the Food and Agriculture Organization (FAO) of the United Nations from 1950 to 2009 up to the peak in 2003 (black) and subsequent decline (red). (B) Shows the rising contribution of rays to the taxonomically-differentiated catch. Log ratios >0 occur when more rays are landed than sharks.

Global trade

The map shows main shark and ray fishing nations (grey-shaded) according to their percent share of the total average annual chondrichthyan landings reported to FAO from 1999 to 2009. The relative share of shark and ray fin trade exports to Hong Kong in 2010 are represented by fin size (Dulvy et al. elife 2014).
