A guideline for collection, analysing and preparation of report on material collected by a biologist-observer on board a commercial trawler (Draft)

Main outlines of E. superba material collection (sampling from commercial catches) and positions of samples examination are reviewed and described. These positions include mass-measuring of body length, examination of maturity stages composition (biological analysis), feeding activity observation and body weight determination. Periodicity of sampling and volume of samples for every position of observation are included. Several proposals regarding to Formats filling and Report of biologist-observer construction are included also. These proposals are suggest to consider during WG-KRILL-92.
