Competition between wild and captive-bred Penaeus plebejus and implications for stock enhancement

Competition between wild and captive-bred Penaeus plebejus and implications for stock enhancement

The mechanisms that drive density dependence are rarely studied in the applied context of population management. We examined the potential for competition for food and shelter and the resulting demographic density dependence to influence how well populations of the eastern king prawn Penaeus plebejus Hess can recover following marine stock enhancement programmes in which captive-bred juveniles ...

Author's personal copy An integrated comparison of captive-bred and wild Atlantic salmon (Salmo salar): Implications for supportive breeding programs

Supportive breeding is a strategy consisting in maintaining a pool of locally-adapted wild genitors in captivity whose offspring are released in the wild at an early developmental stage. In this study, we tested the utility of this strategy in preventing phenotypic and genetic divergences between captive-bred and wild animals that could be detrimental for wild populations. Combining microsatell...

Reintroduction of captive-bred animals

The Hustain Nuru region of Mongolia’s Chentai Mountains is one of the country’s most pristine wild areas. Valleys and slopes harbour steppe vegetation such as fescue, brome grass and feathergrasses, while birch woods grow in the upper elevations of this relatively low lying mountainous region. A diverse range of wild fauna including marmots, lemmings, red deer, wild sheep, polecats, Pallas cat,...

Captive Bred, Adult Giant Clams Survive Restoration in the Wild in Seychelles, Indian Ocean

Coral reef restoration focuses on scleractinian corals, excluding other groups that provide structural complexity to these threatened ecosystems. Giant clams share the role of ecosystem engineers alongside corals in the Indo-Pacific, but overfishing has caused widespread local extinctions. Aquaculture reduces pressure on wild populations and captive bred juveniles have been used to restore exti...
