چکیده انگلیسی
The onset and duration of the production season is controlled by the sub-surface light climate. Differences in depth and tidal mixing in the Irish Sea give rise to regional variation in the timing and length of the production season. Maximum spring bloom biomass in coastal and offshore waters of the western Irish Sea (23 and 16 mg chlorophyll mâ 3, respectively) compares with values of up to 44 mg chlorophyll mâ 3 in Liverpool Bay and elevated production and biomass in the latter is attributed to enrichment. There is no evidence that enrichment and changes in nutrient ratios have caused major shifts in phytoplankton composition in Liverpool Bay. Species of Phaeocystis are found throughout the region in most years and together with other microflagellates can dominate the spring bloom. Red tides of dinoflagellates are rare events in the Irish Sea but regular monitoring of phytoplankton in the vicinity of shellfish beds has revealed the presence of toxin-producing dinoflagellates in the Irish Sea.
