Crabs and Critters at Helford Passage

To finish off the Mega Shoresearch weekend in style the Shoresearch volunteers and I drove up to the Helford for a public event called 'Crabs and Critters'. The sun came out and the weather was fabulous. Approximately 40 people joined myself and the Shoresearch volunteers to explore this muddy but highly producive shore on Bar beach next to Helford passage. It was amazing how many species were found and a stream of excitable kids clutching crazy creatures kept myself and the Helford marine conservation group volunteers busy answering loads of questions! Top finds included a beautiful greater pipefish (I think found by Maddie Lydon) some MASSIVE velvet swimming crabs, a very strange looking hermit crab - Pagurus prideaux that lives inside a cloak anemone. Beautiful Calliactis parasitica - hermit crab anemones. Strange jelly like blobs were common in the shallows - I am still trying to find out what these are! 
To round the event off in style we were lucky to be able to meet with Lynda and Simon Filmer, local fishermen who showed us a fantastic pair of large brown crabs! It was a great chance to introduce Cornwall Wildlife Trusts new project Cornwall Good Seafood Guide, which highlights the abundance of sustainably harvested seafood in our county. Lynda and Simon talked to us all about how they catch shellfish using pots and nets and we all saw first hand the power of the edible crabs pinch! 

Thanks to Jake, Chloe and all the volunteers who carried out a timed species search and walkover survey, and thanks to the volunteers from Helford Marine Conservation group for a most enjoyable day!

Call to Action for MCZs

It was a fantastic turnout at last weeks Shoresearch training evening. Thanks to all those who came from all ends of the county. A total of 27 volunteers attended, including a number of new recruits, several experienced VMCA committee members and volunteers, several marine scientists, local marine lecturers and even staff from Natural England.

It is really great that so many people want to get involved with the Shoresearch programme. I think it bodes well for the year to came and hope that we get a good set of results. Collecting good quality verifiable records of rare shore species will be vital as this summer will be last chance we have to provide much needed data to back up the next tranche of MCZs.  We need a coherent network of Marine Conservation zones around our coast for the long term benefit of our valuable marine habitat and we only have until September to do this so this is a real call for action! 


Sites we need to get data for are Mounts bay rMCZ, Lands End rMCZ, Newquay and Gannel Estuary rMCZ , Hartland point to Tintagel rMCZ, and St Ives Bay.
It is important that we get out and survey as much as we can in these areas this year as the data collected will be really useful in arguing the case for these zones will be vital to ensure that we get a cohesive network of MCZs throughout our waters.

Keep looking out for core species and don't forget that there are a few more species not included that will be really significant if you find them: these are;

  • Eel grass (live, not washed up on the beach)
  • Stalked Jellyfish - you must take good macro photos and get GPS positioning to go with the photos.
  • Giant Goby for more information on these see my earlier post.
  • Peacocks tail sea weed,
  • Maerl beds,
  • Honeycomb worm reefs,
  • Under boulder communities (boulders are classed as rocks larger than 25cm diameter and there must be several encrusting species - ascidians, sponges, bryozoans, keel worms etc living beneath the rocks. Please take lots of photos,
  • Couches goby, 
  • Gooseneck barnacle Pollicepes pollicepes 
  • European Eel,
  • Native oyster,
  • Mussel beds  -where mussels grow on soft substrates and themselves create a new habitat



Don't forget carrying out a survey is easy and if you can't make many of the organised survey dates you are encouraged to go out and carry out your own shoresearch. All you need is a digital camera, a recording sheet (which can be downloaded here) and a GPS or GPS enabled smart phone.
Please remember though to keep safe on the shore and follow the sea shore code!

Send your data and photos in to me at matt.slater@cornwallwildlifetrust.org.uk

Don't forget you can also use the Shoresearch Cornwall dropbox - just drop me an email and I will send you an invite!
