2. Fishing for structure; can we describe normal patterns in toothfish fishing operations using catch and effort data?

   Abstract:  We describe the typical steps involved in demersal longline fishing operations for ... toothfish in CCAMLR fisheries and link those steps to the variables recorded as part of the CCAMLR catch and ... effort data reporting system. We then describe statistical properties of the recorded variables and how ... more difficult to evaluate given the wide range of influences that may affect recorded values for a ...
