Clams responded to the spawning stimulus by extension of the foot, swelling and extension of the mantle, swirling of the whole body, rapid opening and closing of the valves, ejecting of white material from the excurrent siphon, and subsequent contraction of the adductor muscles. Successful spawning of all individuals occurred with the use of gonad extract. Developing homogenized extract was not as effective in inducing the broodstock to spawn. Gametes were released through the excurrent siphon located at the posterior end.19 p.SpawningMud clamBivalveReproductive patternAnodontia edentulaLG 993.5 2008 B4 B33Thesisbivalve culturespawningclamsreproductionAnodontia edentulaSDG 14 - Life below waterSDG 15 - Life on land
