How is #fisheries management evolving? Chris Harrod tells us how #StableIsotopes can be used to understand #fish #ecology. #LoughNeagh and #SteangfordLough were treated completely differently.

Working on submitting destructive sampling permits for #StableIsotope analysis of #CapeFurSeal tooth enamel, fish #otoliths and bone collagen.
Here is the seal plan: 🦭
Comparing carbon and oxygen SI of #MiddleStoneAge seals from #KlasiesRiverMainSite and #BlombosCave with #LateStoneAge seals from #Hoffman’s/Robberg and #NelsonBayCave
Planning to compare the archaeological samples with present day seal populations to see if the #foraging environments have changed.
