    Abstract

    Vessels operating in the krill fishery in CCAMLR’s Convention Area are required to directly estimate the green weight of krill caught (Conservation Measure 21-03, Annex B). This requirements was introduced for the 2012/13 seasons, and the estimation methods were revised at WG-EMM-13 and WG-EMM-14. Estimates of green weight and parameter values are reported in each vessel’s haul-by-haul catch and effort data (C1 data).

    Vessels fishing in 2014/15 used five methods for the direct estimation of the green weight of krill caught: codend volume, holding tank volume, flow meter (method 2), flow scale and meal conversion.

    This paper provides a preliminary summary of the data reported so far in 2014/15 (to May 2015).
