Automated data processing using Echoview
Abstract: Increasing volumes of acoustic data are being collected which necessitates a reappraisal of many of the current methods for data processing and analysis. For some acoustic data sets manual processing is no longer an option; the large size of the data set is preventing analysis. This

A noise removal algorithm for acoustic data with strong interference based on post-processing techniques
Abstract: The use of fishing-vessel-based acoustic data has been recognized by SC-CAMLR as an important way to estimate the distribution and relative abundance of Antarctic krill (Euphausia superba), yet the quality and even the utility of the data may be seriously degraded by interferences due to

Semi-empirical acoustic estimates of krill biomass derived from simulated commercial fishery data based on single-frequency acoustics
Abstract: Single frequency (38 and 120 kHz) acoustic and associated net data were extracted from US AMLR datasets and used to mimic data that might be collected by the commercial fishery during the fishing seasons. From these data we develop semi-empirical indices of acoustic biomass in a

Standardisation of commercial CPUE
Abstract: This paper reports analysis of CPUE data on cod in the Barents Sea. The potential of fleet effort standardisation is explored based on vessel calibration factors, which are established when vessel trawling operations take place at acceptable proximity in time and space. The

Assessment models for Patagonian toothfish in research block 58.4.3a_1 of Division 58.4.3a, Elan Bank for the years 2005-2014
Abstract: We made two sensitivity runs of age-structured and two fisheries (≥1300 m and < 1300 m) CASAL models for stock status assessments of Dissostichus eleginoides in the research block 58.4.3a_1 following the recommendations of the WG-FSA-2014 meeting. Two runs were carried out: including
