My research focuses on #population assessment methodology, mainly #fisheries #stockassessment. I focus on integrating diverse data types in a #likelihood framework. I also coordinate the #CAPAM initiative and its workshop series and special issues.

My research is at

Critical mass interpretation of quantum mechanics.
A “pilot wave” is created by the source as sub-particles
Particles and sub-particles interact
Particles can be observed and sub-particles currently cannot
There must be a critical mass of sub-particles to form a particle

You think stock assessment is complicated, try understanding #entanglement in #QuantumMechanics

Hard to find a simple but accurate explanation on the web or #YouTube so I had a go explaining myself. Feedback please #Physics #QuantumPhysics #Quantum

What do you think about using a low probability of exceeding a limit reference point as a exceptional circumstance in a harvest strategy rather than a harvest control rule control point? The Management Strategy Evaluation #MSE establishment doesn't appear to like it

Looks like it. Not sure if the policy is still no interaction with international scientists or attending international meetings, or just so much uncertainty people can't committee. Not a good way to celebrate the 75th anniversary.

Probably those that are open access. An AI that uses all Journal articles (i.e. those under subscription) and no social media would be awesome. That's possibly why DeepSeek is soooo good 😜I considered making an AI based on CAPAM papers, but it appears only full training is worthwhile.

Hi Tim. Thanks for the interest in CAPAM. Jason Cope has a paper on info limited in the special issue, but Good practices have yet to be fully identified. The next CAPAM workshop is on info limited methods, possible early 2026. I hope you can make it.

Hi Everyone,

CAPAM’s special issue on Fisheries Stock Assessment Good Practices is finally completed.

Fisheries stock assessment has a long history, but it is far from a mature well-organized science with standard practices. Each stock assessment author has their own modelling preferences, and inconsi...

On flight to #Iceland watched series about #QuotaManagement and #fishing in Iceland based on real events. Not sure how much is true, interesting, similar things happened in #NewZealand. (In good Icelandic tradition, there is lots of sex, nudity, drugs, and alcohol) en.wikipedia.org/wiki/Blackport
