| General location information: |
Faxaflói., West coast. HAB Area code(s): IS-01 |
|
| Additional location information: | On May 20th, in the traditional spring survay of MRI, considerable number of A. tamarense and A. ostenfeldii cells were found in netsamples at the station in the outer part of Faxaflói. Because of these findings it was considered urgent to get samples from the inner area, specially in Hvalfjörôur, where there are rich beds of blue-mussels. The monitoring of harmful algae was not on the programme in this area and therefore the following information is based on relatively few samples, not systematically collected. | |

| Chlorophyll concentration, if known: | µg/l | |
| Additional bloom information: | Around June 20 the cell numbers has dropped to several hundreds. Further sampling which was carried out in July (13 and 19) and in August (15 and 31) showed that Alexandrium cells were absent in net samples at these stations. | |

| Management decision: | It was decided to ban all harvesting of shellfish within the inner part of the bay. | ||||||
| Additional harmful effect information: | In the innermost part of Hvalfjörôur (st.1) samples of mussels were taken for mouse testing PSP. The sampling was carried out at the following dates 24/5, 27/5, 6/6, 14/7and 22/8. In all cases, PSP was below the detection limit. | ||||||
