Dear Dr Duckworth;
Reading your mail to Edna re. sponge growth, I'll be very gratefull if I can
receive a reprint or a copy of your paper:
Duckworth AR 2001. Farming sponges for chemicals with pharmaceutical
potential. World Aquaculture, June: 14-18.
At this stage I'm not trying to develop such farming for the pharmaceutical
industry, but just to study sponge growth for few Dictyoceratida species;
we'll start our work next march, in the south of Tunisia, in "El Biban
Laguna". I started collecting "mothers" sponges from the sea in October 2000
and in August 2001; but they died during the transport from the collection
point to the lab, despite a very strong (and clean) water current. We'll re
try again next march as water temperatures will be lower than in May-August,
and hopefully, the mothers will survive easily for the transport as well as
the manipulation, till the fixations of the small pieces in the final farming
place. Water temperature is an important parameter to deal with, mainly for
latitudes like the southern Tunisian ones (ranging from 33 to 36 ° north).
Sincerely
Kerim
