Dolabella auricularia research

June 22, 1999
From: Sandeep K. Singh

HI BILL,
You will remember I am looking at the reproductive biology of Dolabella auricularia, in Fiji. Very little has been done on it. The method I thought that would be appropriate is the gonad index by area. Do you have any suggestions?

Please let me know as soon as possible
Your kind help will be very much appreciated
thanks,
Sandeep

Dear Sandeep,
I am not an expert in ecological methodology and do not know of the Gonad Index by Area method that you mention. A couple of papers which have looked at aspects of Sea Hare growth and reproduction which may give you ideas on methodology are:

* Pauly, D; Calumpong, H (1984): Growth, reproduction and mortality of the sea hare Dolabella auricularia (Gastropoda: Aplysiidae) in the Central Visayas, Philippines. Marine Biology 79, 289-293.

* Audesirk, T.E (1979) A field syudy and reproduction in Aplysia californica. Biological Bulletin, 157(3): 407-421.

Whatever method you use, it may be worth measuring the relative abundance of egg masses as well, as it may prove an easier way to predict the size of the Sea Hare populations. However it may be difficult to distinguish Dolabella's egg strings from those of species of Aplysia.

The Pauly paper is quite interesting because it suggests using the techniques employed by fish biologists. What you will have to do is find a method that you and your supervisor are happy with, because day to day problems will arise which can only be solved by people with local knowledge.

Perhaps someone reading this message can give Sandeep more advice?

Good luck,
Bill Rudman
