The queen conch, Lobatus gigas, is a very important fisheries resource among Caribbean countries due to its cultural and economic value (Appeldoorn et al. 2011). However, the increase in its consumption during the past decades has caused its overexploitation (Lawrence and Phillips 2013). The inclusion of this species under Appendix II of CITES in 1992 has allowed a more controlled trade and the establishment of specific fishing quotas to reduce threats in the local populations (Appeldoorn et al. 2011). Nevertheless, illegal and unregulated fishing and trade is still happening nowadays (Oxenford et al. 2007).
