    Ensis arcuatus has a relatively short larval life and good larval survival rate. Moreover, a new method has been developed to induce spawning, which could be a useful tool. The next step in developing the aquaculture potential of E. arcuatus should be to compare growth rates under various conditions.
    Adult individuals of Ensis arcuatus spawned in the hatchery from January until April. Neither thermal shock, stripping gonads, nor UV-treated seawater flow were effective as spawning methods. Changing water levels by simulating tides was the only successful method, the first individuals spawning 2 h after the beginning of induction.
    Embryos were then sputter-coated with gold before observation in a Philips XL30 SEM. Confirmation of prodissoconch structure in Ensis arcuatus was achieved using live 5-day-old larvae by cryofocusing, in which live larvae were frozen in liquid nitrogen to avoid the alteration of larval structures after SEM preparation procedures.
    In moderate wave exposure, Ensis ensis may be replaced by the larger Ensis siliqua (Holme, 1954). Lifespan. The lifespan of Ensis ensis is likely to be in excess of 10 years. The other two British species Ensis siliqua and Ensis arcuatus are also very long-lived, with a lifespan of up to 18 years (E. Fahy pers. Comm.).
