Currently, it is illegal to commercially dive and fish for abalone. They can only be obtained through recreational diving or abalone farms.
How might a changing climate affect shellfish?
With the rising acidification and warmer temperatures of our ocean waters, many marine creatures are being affected and our shellfish are no exception. Currently, there is a rising amount of carbon dioxide in our atmosphere and our oceans are absorbing much of it. This in turn lowers the pH of the water, meaning it becomes more acidic. This makes it harder for shellfish to create their calcium-based shells and impacts their survival.
Rising ocean temperatures could potentially affect shellfish spawning time, increase the spread of disease, and decrease the amount of oxygen in the water.
