Large
growths of an invasive species of a didemnid ascidian (sea squirt) called
Didemnum
sp.
may* have reached
the east coast of Ireland. It appears that large gelatinous growths
of a didemnid are appearing practically all around the world and have now
cropped up off the north European coasts as well as New Zealand and large
parts of the United States of America. These colonial tunicates are regarded
as a nuisance and one of many fouling organism species that attach to boat
hulls, fishing gear, harbour wharves etc.

Liz
Sides, from Duchas in Ireland says that one
of her tunicate taxonomic friends has found what appears to be a large
non-native Didemnum sp
growing prolifically in a marina on the Irish east coast. (*The
identification has not been confirmed yet.)

Ormers,
Haliotis
tuberculata, with a minimum shell
length of 80 mm can be legally collected from the shores of Guernsey.
I discovered
an Ormer of shell
length 11.75 cm on 18 October 2005
on the
shore
at La Valette on Guernsey's east coast - south of St. Peter Port. I wanted
to find out if this Ormer
was still under the same rock. I was not disappointed. This is the second
time I have found an Ormer
in the autumn which has remained under the same rock through to the New
Year. I did not collect it but hope it survives the Ormer
collecting season which continues during large spring tides until the end
of April.
