Record #173847:

Age, growth and mortality of Patagonian toothfish (Dissostichus eleginoides) caught off Kerguelen / J. Ashford, G. Duhamel, C. Jones, S. Bobko.

Title: Age, growth and mortality of Patagonian toothfish (Dissostichus eleginoides) caught off Kerguelen / J. Ashford, G. Duhamel, C. Jones, S. Bobko.
Author(s): Ashford, J.

Date: 2005.
In: CCAMLR Science. (2005.), Vol. 12 (2005)
Abstract: Ages of Patagonian toothfish caught off sub-Antarctic Iles Kerguelen in 1999 were estimated by reading transverse-sectioned otoliths. Randomly interspersed otoliths from reference collections were used to measure precision, and relative bias for age data was estimated to be -0.6 years and residual variance 2.9. Age distributions of toothfish caught by two vessels showed discrepancies due to gear-specific catchability, or difference in available population with depth or season. Age-length keys showed longevity to be approximately 36 years. Total instantaneous mortality Z was estimated to be between 0.09 and 0.12, and there were significant differences in age-at-length data between sexes.
