Conservation Evidence: Evidence Data

Collected Evidence: Collected Evidence: Release captive-bred marine and freshwater mammals to re-establish or boost native populations Two studies evaluated the effects of releasing captive-bred marine and freshwater mammals to re-establish or boost native populations. One study was in the Porto de Pedras estuary (Brazil) and one in water bodies in Florida (USA). COMMUNITY RESPONSE (0 STUDIES) POPULATION RESPONSE (2 STUDIES) Survival (2 studies): Two studies in the Porto de Pedras estuary and water bodies in Florida found that two of three Antillean manatees and two of 14 Florida manatees born in captivity and released into the wild survived for at least one year without further intervention.

The study was in the Catazajá wetlands (Mexico). COMMUNITY RESPONSE (0 STUDIES) POPULATION RESPONSE (0 STUDIES) BEHAVIOUR (1 STUDY) Change in human behaviour (1 study): One study in the Catazajá wetlands reported that engaging policymakers resulted in the designation of a protected area for West Indian manatees.

One study was in each of the North Atlantic Ocean (USA), the Sundarbans mangroves (Bangladesh) and the South Pacific Ocean (Peru). COMMUNITY RESPONSE (0 STUDIES) POPULATION RESPONSE (0 STUDIES) BEHAVIOUR (3 STUDIES) Change in human behaviour (3 studies): Three before-and-after studies in the North Atlantic Ocean, the Sundarbans mangroves and the South Pacific Ocean found that after educational whale-watching tours or an educational exhibition, participants were more willing to change their behaviour to support marine conservation, to donate money to marine conservation, or to cut their fishing nets to save entangled dolphins.

Therefore we have been unable to assess whether or not the action is effective or has any harmful impacts.
