Key messages

  • One study examined the effects of translocating crustacean species on their wild populations. The study took place in the Tasman Sea (Australia).

 

COMMUNITY RESPONSE (0 STUDIES)

POPULATION RESPONSE (1 STUDY)

  • Crustacean survival (1 study): One study in the Tasman Sea found that following translocation survival of southern rock lobsters was similar to that of resident lobsters.

About key messages

Key messages provide a descriptive index to studies we have found that test this intervention.

Studies are not directly comparable or of equal value. When making decisions based on this evidence, you should consider factors such as study size, study design, reported metrics and relevance of the study to your situation, rather than simply counting the number of studies that support a particular interpretation.

Supporting evidence from individual studies

  1. A study in 2005–2007 in one area of rocky reef off the coast of southeastern Tasmania, Tasman Sea, Australia (Green & Gardner 2009) found that two years after southern rock lobsters Jasus edwardsii were translocated, their survival was similar to that of resident lobsters. Survival of translocated lobsters was 96–98% after two years, similar to resident lobsters (98%). In 2005, lobsters were translocated from a site where lobsters grew slowly to a site inside a marine reserve where resident lobsters grew faster. Survival was monitored for two years. Lobsters (n=1,998) were caught in the slow-growth site using baited pots, tagged, and kept in flow-through tanks with ambient seawater until release into the new site 2–3 days later. At the surface, batches of 50 lobsters were released into a net connected to a cage on the seabed. After 24h, all lobsters were released. Lobsters residing in the fast-growth site (2,668 in total) were tagged and monitored for comparison. Translocated and resident lobsters were resampled nine times using 20–60 baited pots. A mark-recapture model based on the number of recaptured tagged lobsters (457 translocated and 797 resident lobsters in total) was used to estimate percentage survival.
