1. Echo integration in low signal to noise regimes: methods of noise estimation and removal

   Abstract:  The results of acoustic surveys, especially in low signal-to-noise regimes, are ... sensitive to the method used to exclude the contribution of background noise from the acoustic data. The use ... of thresholds to reject weak signals during data collection is inappropriate because the noise ... contribution to the above-threshold-signal cannot later be removed in post processing. The only solution is to ...

6. Length-at-age juvenile Patagonian toothfish Dissostichus eleginoides

   Abstract:  The fishery for Patagonian toothfish is one of the most valuable in the CCAMLR Area ... . Age based models are used to assess the status of the stocks of this species. Although age can be ... estimated using otoliths it has proven difficult for these to be validated. During a recent trawl survey the ... length density of juvenile toothfish in the catches had a clearly defined polymodal distribution. The age ...
