Concerning message #17301:

Hi

Many families in the coastal regions in Visayas and Mindanao islands of Philippines use these eggs for food, and this is slowly growing popularity in different areas of the country.

As I very recently learned about people making a living out of sea slug eggs, I was concerned as to its effects in the reproduction of the species. Are there any significant effects of this human activity to their reproduction?

thank you in advance.

Dear Lorraine,

Sea hares  such as Dolabella auricularia produce many more eggs than are needed to maintain their population levels so unless  human egg gatherers are extremely efficient, I suspect enough larvae will survive to produce the next generation. However that is just a guess. To be sure you would need to do a proper scientific study over a number of years to see if Sea Hare and egg mass numbers increased, decreased or remained stable. Have a look at an earlier reply I gave [message #8577] to a question on the ecology of this species in the Philippines for some relevant references. Unfortunately, over-fishing or over harvesting is a major problem worldwide.

Best wishes,
Bill Rudman
