Instructions
Potassium Chloride
Before handling a sea urchin, learn what type it is. Some sea urchin spines are poisonous.
Inject the sea urchin with potassium chloride. The injected solution is 0.55 grams of potassium chloride diluted in distilled water. Inject 1-2 milliliters to get them to produce eggs or sperm.
Check around the anus for sperm or eggs. Sperm will be a white viscous fluid while eggs will be a yellow or red viscous fluid. It may take about 10 minutes. Make sure to keep them sprinkled with sea water.
Electrical Current
Capture a sea urchin keeping it moist with sea water.
Use a bell transformer to reduce the 60 cycle alternating current coming out of the socket from 110 volts to 10 volts.
Take electrodes attached to the transformer and touch them to the damp outer skin of the sea urchin.
Check the anus to see if sperm or eggs are being secreted.
