Summary of sawfish work taking place in Mexico, Central and South America. Ruth H. Leeney Two sawfish species – the smalltooth and largetooth sawfishes (Pristis pectinata and P. pristis) – are known to have occurred historically in Caribbean and Central American (Atlantic) coastal seas, whilst only the largetooth sawfish is known from the eastern Pacific. The current status of sawfishes in the waters of Mexico, Central America and the west coast of South America is poorly understood. Until recently, little upHtoHdate information was available from these regions but happily, since 2014, numerous research projects have developed to address these data gaps. Many of these projects are multiHcountry collaborative efforts, which facilitates the sharing of resources and expertise. What follows is a summary of the projects that have shared information on their research and conservation activities with the SSG, but if you are working on sawfishes in Mesoamerica or South America and don’t see your project mentioned here, please do get in touch! In Mexico, Océanos Vivientes AC is conducting a nationwide survey of historical and current presence of sawfishes, in order to evaluate the conservation status of sawfishes in Mexico. The team hopes to work towards a change in Mexican legislation relating to sawfishes. Océanos Vivientes is also collaborating with Conservation International to develop sawfish research in Colombia. MarAlliance is working in Belize, Cuba, Guatemala, Honduras and on the Caribbean coast of Mexico. Their work on sawfishes is part of a broader programme which involves working closely with fishing communities to monitor marine megafauna, especially elasmobranchs. They hope to assess the current existence of sawfishes in each of their study regions, document historical occurrence, distribution and local uses of sawfishes, and identify strategies to encourage the recovery of any remaining sawfish populations. In Peru, Planeta Océano launched a sawfish research programme in early 2015, involving a training programme which was run in collaboration with Protect Africa’s Sawfishes. Following the training, course participants and Planeta Océano staff conducted interviews at numerous fishing ports and landings sites in northern Peru, and interviews will be conducted further south, later this year. Very recent captures of largetooth sawfish have occurred in northern Peru, including one adult caught and released alive in February 2015. Planeta Océano has also built collaborative links with teams in Ecuador, El Salvador and Costa Rica, supporting them to collect data on sawfishes using similar methods, and developing community awareness activities and educational materials on sawfishes, to be used throughout the region. Planeta Océanos’ collaborators at the Universidad Laica Eloy Alfaro de Manabí (Ecuador), led by Dr. Rigoberto RosasHLuis, have already conducted 429 interviews with fishermen throughout Ecuador. The most recent capture of a sawfish there was in 2014, in San Lorenzo, northern Ecuador. Fundación Talking Oceans and the Smithsonian Institution is conducting sawfish research in Costa Rica, Panama, Colombia and Ecuador. They aim to assess the current distribution and conservation status of sawfishes in the ETP, as part of a wider project to identify and map elasmobranch critical habitats and assess MPA effectiveness. Fundación Talking Oceans are working with a number of collaborators including Marviva, WWF, USAIDHBIOREDD, Universidad de Costa Rica, Playa Tortuga, Malangwai, SINAC, PRETOMA, Universidad de Panama, ARAP, Planeta Océano and NAZCA. Central and South America are also key regions for sawfish conservation for one particular reason – the cockHfighting industry. CockHfighting is a very popular pastime in many Central and South American countries, and since the midH1970s, sawfish rostral teeth have been the preferred source
