1. Analysis of krill fishery operations in Subarea 48.1: spatial-time distribution of CPUE and fishing efforts

   Abstract:  In previous years we revealed that period 2006-2011 is characterized by the highest ... values of standardized CPUE indices in the Subarea 48.1 for the last 25 years. We continue to investigate ... krill fishery data for understanding reasons of this ‘high CPUE’ regime. The authors present the ... method. We obtained the additional evidence that ‘high CPUE’ regime’ in 2006-2011 is not associated with ...

2. Direct ageing of Antarctic krill (Euphausia superba) – potential utility of eyestalk sections for age determination

   Abstract:  We outline a method for the direct determination of age in Antarctic krill (Euphausia ... superba). Recent studies (Kilada et al. 2012), have shown that annular growth bands are present in the ... endocuticle layer of the eyestalks and gastric mill in decapod crustaceans. Here we report on a preliminary ... proof of concept study using several known age krill grown under controlled conditions at the Australian ...

4. Fitting a von Bertalanffy growth model to length-at-age data accounting for length-dependent fishing selectivity and length-stratified sub-sampling of length frequency samples

   Abstract:  Response-biased sampling in the context of regression modelling occurs when sample ... units are selected with a probability that is a function of the response. In sampling to obtain fish to ... is the response and age is the predictor variable. These sample processes are (i) the actual fishing ... process involving a particular gear, and (ii) the method of on-deck sub-sampling fish for ageing from the ...

   Abstract:  The potential for data poor exploratory fisheries in the CAMLR Convention area to ... recommendations are made for optimizing this potential.  The types of data that have led to successful assessments ... in the past are reviewed. Exploratory fisheries and research questions for subareas without currently ... assessed stocks (48.6, 58.4, parts of 88.1 and 88.2) are summarized. The multi-nation, multi-year ...

Average statistical parameters of swarms in the polygon varied insignificantly from ... survey to survey, while the swarm number varied within the board range from 1 918 to 7 000 and further to ... 1 554 units. Krill biomass in the polygon varied spasmodically within the range from 1 091 to 6 085 ...

8. A sensitivity analysis of a simple krill individual-based model designed to investigate length-based recruitment indices

   Abstract:  As part of the CCAMLR Scheme of International Scientific Observation, observers on ... -board Krill (Euphausia superba) fishing vessels measure the length of individual Krill sampled from ... commercial catches. These extremely valuable data may be used to monitor the state of harvested Krill ... provides insight into the underlying population dynamics. Three main processes drive temporal changes in ...
