2021 was the third best year ever for Marmorkrebs research

At least it was the third best year as judged by number of journal articles. But there were more than just journal articles! At the start of the year, we had what was probably the best popular article written to date about Marmorkrebs.

 

It was a slow year for new introductions, but the one in Macau was a significant expansion in Asia.

 

And finally, I learned of two North American jurisdictions regulating Marmorkebs: Ohio, which seemed to have done it quietly in 2020, and Ontario, which did so quietly starting in 2022.

Ontario prohibits Marmorkrebs

The Gananoque Reporter reminds me of a story I have been watching for almost two years: Marmorkrebs have been added to a list of prohibited species in Ontario under the Invasive Species Act.

 

Marbled crayfish (Procambarus virginalis) and Louisiana red swamp crayfish (Procambarus clarkii) prohibited in Ontario, as of 1 January 2022. Happy new year. 

 

What does this mean in practical terms?

 

Prohibited species cannot be brought into Ontario, deposited, released, possessed or transported in Ontario and cannot be propagated, bought, sold or traded in Ontario.

The regulation includes species-specific exceptions to certain prohibitions, including: Marbled Crayfish, Red Swamp Crayfish: Exceptions allow for incidental capture of these species while fishing in Ontario.

 

This is a weird exemption, because as there are no marbled crayfish to be caught in Ontario, as far as I know.

 

This is the most significant regulation concerning marbled crayfish in North America to date, because Ontario is the largest and most populous jurisdiction that has yet tried to regulate marbled crayfish.

We’ll see if it works.

 

That I am just learning about this today – one day before it takes effect – emphasizes yet again how hard it is to keep track of this sort of legislation. I have alerts set for marbled crayfish and try to track this material as closely as possible. I am making an effort. But this passed me by for eight whole months.

The newest version of Marmorkrebs.org

Marmorkrebs.org is moving to Google Sites.

 

https://sites.google.com/view/marmorkrebs/

 

One major advantage of this change is that Google Sites are much better at switching between desktop and mobile versions of the site, which will make people visiting by using their phones much happier!

 

Since its beginning, the main Marmorkrebs.org website has been hosted by my former employer, The University of Texas Rio Grande Valley (formerly The University of Texas Pan American). Last year, I took a new position. Because of that, I will soon be losing all access to the web hosting provided by that university.

 

I have updated the domain name pointers, so typing “marmorkreb.org” in your browser bar should now go to the new site. If, for some reason, you still need to visit the old, more complete site in the next couple of days, you can go to:

Thank you!
