Effects of autotomy on long-term survival and growth of painted spiny lobster (Panulirus versicolor)on the Great Barrier Reef, Australia
MetadataShow full item record
he effects of autotomy (shedding of appendages) on survival and growth rates of painted spiny lobster were investigated at Northwest Island (23° 18' S, 152° 43' E) during the period 2003–2006. Adult lobsters were captured, tagged, and classified as either uninjured (n = 68), minimally injured (n = 39) or moderately injured (n = 19) depending on the number and type of appendages that were autotomized during capture and handling. Six to thirty-six months after release, 86 lobsters were recaptured (mean time at large = 305 days). Recapture rates of uninjured (64.7%), minimally injured (71.8%), and moderately injured lobsters (73.7%) were not significantly different. Similarly, mean annualized growth rates of uninjured, minimally injured, and moderately injured lobsters were not significantly different. This suggests that the energetic cost of a single episode of autotomy is either negligible or exists as a trade-off with some other life history trait, such as reduced reproductive performance. These results support the use of certain management tools (e.g., size limits) that prescribe release of non-legal lobsters, regardless of their injury status.
