New 🧪paper: We show the importance of selecting several indicators, both diversity and trait-based, to capture the broader signals of change in benthic communities due to bottom trawling activities.

It would be great if we could take a whole country and change the default speed limit to 20mph and then compare it to one left at 30mph. What if it reduced casualties by 25% and with lower risk reduced insurance premiums by £45 a year? Well it did! bit.ly/4gIBPlJ

Started my travels to teach an @icesmarine.bsky.social training course on the bottom trawling risk assessment method that we have been applying in WGFBIT. Currently cruising through Belgium on the Eurostar, continuing tomorrow to Copenhagen after a night at my parents.

In @projectfishistory.bsky.social we're after any historical records of herring fishing and spawning, so hearing about these kind of traps is very useful.

The “E-Bike Effect:” Those who bought e-bikes increased their average daily bicycle use from 2.1km (1.3 miles) to 9.2km (5.7 miles), a 340% increase. The e-bike share of all their transportation increased dramatically too; from 17% to 49%.

E-bikes support fewer car trips.

E-Bikers Ride Much Farther and More Frequently Than Regular Bikers

They are not 'cheating,' but are serious transportation.

Israeli quadcopters shooting children.

And our government continues to materially supporting Israel every day.

Even as Israel rejects a two state solution, votes to fully annex the West Bank, and murders more doctors, nurses, journalists, children.

And our government continues to assist it.

Another critique showing that the Sala et al. 2021 estimate of carbon release by bottom trawling is ridiculous.

It estimates an increase in NW European shelf OC mineralization of 0.27 Mt C yr−1, which is an order of magnitude smaller the previous estimates.

Starting the last day of my travel back from the #ICESASC25 in Lithuania (train ferry combo). The travel was fairly cheap with interrail with the ferry was only £126 return. But it does take 3 days 🙂 @sosbangor.bsky.social @icesmarine.bsky.social

#ICESASC25 was a game-changer! Stepping outside of my usual research into the world of #fisheries has been valuable. Understanding where #GreatCormorants fish is a priority to manage interactions with human activities. New connections and prospectives!

Great to meet lots of collaborators again at #icesasc25. I'm looking forward to the excursion on the Curonian spit today, we'll almost get to Russia.

Great talk on using historical sources to map herring spawning grounds by @georginahunt.bsky.social for @projectfishistory.bsky.social.

Jan Geert Hiddink @jangeerthiddink.bsky.social · 23d

We're using a very wide range of sources to patch together maps of where and when herring used to spawn.

No luck in actually getting tickets though. This happened when I first got to the front of the queue, and after that the tickets were just going to fast.

Jan Geert Hiddink @jangeerthiddink.bsky.social · 27d

Failed to get tickets in the end anyway. Just moving too quickly and anti-bot systems kicking me out the first time.

Jan Geert Hiddink @jangeerthiddink.bsky.social · 27d

I had to restart my phone to make it work. Didn't work from my computer on the train wifi. Anti-bot measures are a great plan but a pity if they get in the way of actually buying a ticket...
