Field Sampling
Laboratory Sampling
Measurement of krill
total volume of krill catch should be measured (dry/wet?)
if sample is large then a random subsample of at least 100 krill should
be taken
measurements should be done by one person to remove observer variation
(see Watkins et al. 1986)
standard length measurement (AT) on fresh animals (ie measurements should
be carried out on board)
sex and maturity stage should be determined according to Makarov and Denys
Preservation of krill
a sample of krill (~50) should be preserved in ethanol for genetic studies
remainder of the sample (or a representative subsample if sample large)
should be preserved in formalin
Data entry
All relevant data (to be determined) should be entered onto computer
prior to the termination of the cruise. A suitable electronic data entry
sheet format will be made available to all participants.
