Enrichment devices for green turtles (Chelonia mydas) reared in captivity programs.

Environmental enrichment supports the well-being and welfare of captive animals. In the current study, the most suitable form of enrichment device for captive green turtles (Chelonia mydas) was investigated, to support head-start programs rearing turtles for release into their natural habitat. Fifteen-day-old turtles (113-114 g initial weight, n = 75) were randomly distributed into 15 experimental plastic tanks, comprising 5 treatments across three pools of each condition.
