Abstract
A previously published model is used to assess the effects of potential disturbances on a sealoch ecosystem Nutrient enrichment on its own has little or no effect and the only major consequence of enhanced or depressed light conditions is a phase shift in the spring bloom For the fjordic systems modelled the most important type of disturbance is a reduction in grazing which can result in high levels of phytoplankton biomass for much of the year In the absence of grazing control primary production in these systems becomes nutrientlimited and it is concluded that the most serious threat would be posed by a reduction in grazing rate combined with an increase in nutrient loading
