Day two of the seasearch course started relatively early (for a Sunday). We met at Towan headland in Newquay by the old lifeboat station, and the car park started to fill with divers in various states of getting ready. Most of the course participants were diving, but three of us (including me) were snorkelling. We accessed the water down a natural rock ramp, which was much less steep than the old lifeboat slipway, and entered the water at 9.30, around two hours after local high water. As I was only wearing a summer 3mm wetsuit the cold shock was a little bracing and left me hyperventilating for a good twenty seconds, as well as giving me the start of a wonderful ‘ice-cream’ headache. Visibility was around 5m as we began to snorkel. We remained on the surface so as not to interfere with the divers surveying below us, which restricted us to observing what was in the water column or on the shallower rocks, and consequently saw mostly sand eels and spider crabs. We were joined by a female grey seal who kept us company for a while before disappearing to visit the divers. As we swam back to the exit point I could see the silhouette of the seal below me, just at the limit of visibility.
After coffee and biscuits, we moved across to the other side of Fistral beach as the tide continued to fall to meet Frances and the other participants for the rockpooling session. This was more productive for me personally, catching a large Shanny (Lipophrys pholis, and thanks to Fiona for spotting it), and later a long-spined Sea Scorpion (Taurulus bubalis). The Sea Scorpion was a complete surprise as I ran my hands through the unlikeliest looking crevice in the rock behind where we’d left our bags and found quite a sizeable fish at about 15cm long.
As the tide started to come in we used a seine net to sample over the sand in the surf. It was hard work, and involved coordination so that the top and bottom ropes were hauled in at similar rates, and that the bottom rope was kept low to avoid all the specimens escaping underneath. We found a prawns and shrimps, a juvenile flatfish, and a number of Lesser Weaverfish (Echiichtyhys vipera), which questioned the wisdom of so many swimmers going into the water barefoot. The day ended with pasties on the beach.
Overall, it was a great weekend. I learned a lot, in good company, and hope to return next year to do the seasearch observer course.
