Threats

Major Threats
Holthuis (1991) stated that this species was not actively fished at the time, although it was "taken in commercially attractive quantities [ca 10 kg/h] during exploratory trawling operations in the western Caribbean Sea [Nicaragua and Colombia]". This species was caught in a few hauls at a depth of 300 m off the coast of Venezuela, close to Margarita Island (Saetersdal 1999). The situation was much the same in 2002, when Tavares (2002) stated that this species was "still not actively fished for at present".

According to the FAO's 1994 assessment of Caribbean fisheries; crustaceans, including lobsters, were not considered overexploited. However, this is an overall estimate, and does not give an accurate picture of local stocks which can vary greatly (CEP 2001). Furthermore, a major threat to lobsters in the Caribbean is the destruction of mangrove forests, which adversely affects juvenile nursery grounds and renders the coastline vulnerable to erosion (CEP 2001).
