Wilson, J H

Concentrations and size distributions of Ostrea edulis L larvae were recorded in Kilkieran Bay, Co. Galway, Ireland, during 1984 and 1985. Larvae were most abundant during July and August in both years. Large larvae ≥ 250 µm were homogeneously distributed through the vertical water column. Higher percentages of smaller larvae ≤ 250 µm were recorded at stations near the mouth of the bay than at stations on or near the beds. Variations in tidal amplitude and low salinities caused displacement of larvae from the beds. There were no significant losses of larvae from the inner bay.
