SeaUrchinGametecollection
Spawning can be induced in adult sea urchinsby injecting 1 ml of a0.5M KCl solution into several sites in the soft membrane around the mouth. Within minutes, the gametes should appear: the sperm are off-white, the eggs are tan to orange. Collect the sperm by inverting themale onto a small, dry petri dish. After several minutes, cover the sperm and put on ice. Collect the eggs by inverting the female on......阅读全文
