Dear Dr. Kulka,

I know some friends working on this rare species, kindly here some of publications that you may have:

Hi,

there are very few articles on this species and the grey literature is quite limited too except for the fisheries data. But we have published an article on its genetic structure in the North Atlantic, including some samples from Canada, Maine and Greenland.

Here is the link: https://www.researchgate.net/publication/262698568_Genetic_structure_of_the_lumpfish_Cyclopterus_lumpus_across_the_North_Atlantic

hope this helps.

Cheers,

Chris.

Hi, I work on lumpfish in Norway. We are trying to set up a working group with a few other participants from the Nordic countries (Iceland, Denmark- Greenland, Sweden, and the Faroe islands). Also have a look here:

You can contact me if you have any questions! Best wishes, Caroline

Here is one that I think you dont have already

Please take contact if you have any further questions

We regularely conduct investigations of this species in the Barents Sea at PINRO. Some article were published (mainly in Russian). One PhD thesis was prepared 1-2 years ago by Sergey Rusyaev. And a monography on lumpfish was published by Oksna Kudriavtseva (Murmansk Marine Biological Institute).appr. 5-7 years ago. If you need I can try to prepare the list of Russian publications on this fish.

Thank you all for your quick and thorough response

I undertake long-term monthly sampling in the Bristol Channel, England. Cyclopterus lumpus is one of the species I have been sampling monthly for the last 35 years.  In recent years it has become less common, but I am hopeful now we are entering a cooling phase in seawater temperatures that numbers will pick up. 

We also observe its breeding along the south coast of England because during the lowest spring tides in spring when the large females are exposed on the lower shore in pools because they will not leave their eggs.

Yes, sorry, wrong sex. Thanks for the correction.

We have found very little on maturity of lumpfish. We do have some data from Canadian surveys but the L50s from those data are lower than the "conventional wisdom". I anyone doing work on maturity?
