This Caribbean Billfish Management and Conservation Plan has been prepared to reverse the trend of declining stocks of billfish species within the Western Central Atlantic Ocean and its adjacent seas, and to address unsustainable fishing practices. The Members of the Western Central Atlantic Fishery Commission (WECAFC), Caribbean Regional Fisheries Mechanism (CRFM), Central America Organization for Fishery and Aquaculture (OSPESCA) and the Caribbean Fisheries Management Council (CFMC) are concerned about the billfish stocks in the region. Therefore, they developed together, through the Recreational Fisheries Working Group, and in close collaboration with all key stakeholders in the Consortium on Billfish Management and Conservation (CBMC) this plan in the period 2015–2018. The plan recognizes the mandate of the International Commission for the Conservation of Atlantic Tunas (ICCAT) over the billfish stocks, and supports the implementation of the ICCAT recommendations in the region. The objective of this Plan is to outline and guide the implementation of a suite of billfish management measures over a five-year period at regional and sub-regional scales to help secure the potential future benefits that can accrue from billfish stocks in the Caribbean. The overarching goal is to improve the management and conservation of billfish stocks.
