Three phytoplankton species blooms which have been reported harmful to fisheries in UK waters are discussed: (1) The armoured dinoflagellate Gonyaulax tamarensis has caused harmful levels to humans of paralytic shellfish poison in most years since 1968 in shellfish from sites on the British east coast between 54.5°N and 56.7°N. The months of maximum toxicity are May and June. (2) Red tides of the naked dinoflagellate Gyrodinium aureolum have caused mortalities of wild marine animals in south-west England in 1978 and in North Wales in 1971, and killed farmed salmon in the west of Scotland in 1980. These red tides occurred between August and October. The dinoflagellate occurs all along the west coast of Britain and is often abundant at fronts. (3) Blooms of flagellate X, possibly a species of Olisthodiscus or Chattonella, have killed farmed fish in sea-lochs on the west coast of Scotland in 1979 and 1982.

Data Records

The data in this sampling event resource has been published as a Darwin Core Archive (DwC-A), which is a standardized format for sharing biodiversity data as a set of one or more data tables. The core data table contains 3 records. 2 extension data tables also exist. An extension record supplies extra information about a core record. The number of records in each extension data table is illustrated below.

  • Occurrence 

This IPT archives the data and thus serves as the data repository. The data and resource metadata are available for download in the downloads section. The versions table lists other versions of the resource that have been made publicly available and allows tracking changes made to the resource over time.
