Recent reports indicated that population numbers of the Cuban crocodile are showing signs of recovery; the population in the Zapata swamp is estimated at between 3,000 and 6,000 individuals (6). Active measures are underway to ensure this population remains well protected but a further important conservation priority is the establishment of an alternative wild population (5). In the 1950s to 60s, thousands of Cuban crocodiles were taken into captivity to be farmed for their skins and the population of captive animals is today substantial, one farm has recently been given CITES (Convention on International Trade in Endangered Species) approval to trade internationally (6).
