Monday: an admin day mainly, along with preparation of the presentation I’m giving on Thursday and some checking of the details belonging to some scales samples sent to MSS for genetic analysis last year. Tuesday: some more presentation prep and then sorting out scales to send to the Univ. of Southampton for analysis of their marine isotopes. These can show where fish were feeding in their last summer in the sea and I’m interested to see, for salmon, if these are the same areas for Spring and Summer MSW and different for 1SW grilse (or not) and for Sea-trout, if the feeding areas of 1SW and 2SW are different (going by tagging recaptures in the sea, they should be) and if the Whitling do something different again. I’ve long suspected that these little fish don’t go far out to sea but may be just local in their feeding areas. Would be very useful to confirm this. Wednesday: travelling down to Telford, in Shropshire for an EA / IFM / AST meeting on Stock Assessment in England. Thursday: particularly interested to hear from those who set up the English Conservation Limits system 20 years ago how it was very much an interim methodology but has never actually been revised since, though more and better data now available. A lot of discussion on presentation too, on how the system could be better explained and so better understood and better supported by anglers. Also interesting to hear how Biological Reference Points could be entirely in the freshwater, juvenile phase: Friday: travelling back from Telford.
