Part 2 of the stable isotope project will be analyzing sea catfish using carbon and oxygen stable isotope analyses
Otoliths are calcium carbonate structures or “stones” in the inner ear of most fish 🐠
The sea catfish otoliths are very round, but you can also get different shapes like this
The goal is to determine the season of catch and to reconstruct body size

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

@CliveTrue Yup! I worked with to study age-structure impacts of MPAs on groundfish for my MS and working on a otolith project currently, looking at holocene of gadoids

Hi all, time! Im an aquatic ecologist working in water science in rainy Australia. My was on freshwater fish early life history, with lots of time fiddling with of a really cool fish, Mogurnda adspersa. My interests include and data science in general. Pic is of a small native fish in the Canberra region, Galaxias olidus. For more: www.danswell.org
