Collected Evidence: Collected Evidence: Establish handling and release procedures for accidentally captured or entangled (‘bycatch’) reptiles One study evaluated the effects on reptiles of establishing handling and release procedures for accidentally captured or entangled reptiles. This study was in Canada. COMMUNITY RESPONSE (0 STUDIES) POPULATION RESPONSE (1 STUDY) Condition (1 study): One replicated, controlled study in Canada in a captive setting found that recovery of painted turtles after a long period of being held underwater was similar when turtles recovered out of the water or in the water.

This study was in the USA. COMMUNITY RESPONSE (0 STUDIES) POPULATION RESPONSE (1 STUDY) Survival (1 study): One replicated study in the USA found that few diamondback terrapins died in crab pots fitted with mesh chimneys.

One study was in each of the Caribbean Sea, Costa Rica and the Republic of Korea. COMMUNITY RESPONSE (0 STUDIES) POPULATION RESPONSE (2 STUDIES) Survival (2 studies): One replicated study in the Caribbean Sea found that from a released group of green turtles that included some accidentally caught and some head-started individuals, some survived for at least several months in the wild. One replicated study in the Republic of Korea found that green turtles caught in pound nets all survived for at least two weeks to a year after release. BEHAVIOUR (1 STUDY) Behaviour change (1 study): One controlled study off the Pacific coast of Costa Rica found that the behaviour of longline-caught sea turtles following release was broadly similar to free-swimming turtles.
