The dif erent economic levels of marine resource use in the Quirimbas
Marine resource collection in the Quirimba Archipelago can be divided
into a number of categories depending on the level of investment needed
by the i sher:
Little or no personal investment
The main group in this category are the
crew of the seine net i shing boats who need to make very little invest-
ment to start i shing. Some have their own strong shoes to protect against
urchins, others have their own masks but the majority have neither. Young
boys go straight into the seine net i shery and strangers to the island are
also free to enter this i shery.
The women's invertebrate i shery requires very little personal invest-
ment, needing only a bucket or other container. Women collect inverte-
brates from the intertidal at Santa Maria and Pantopi, and also make trips
on boats out to exposed sand banks at low spring tides. Young children
who collect small species of mollusc from the upper intertidal, and women
who collect these shells for occasional meals can also be included in this
category.
Moderate personal investment
Trap i shers need a dugout or plank-
constructed canoe with two outriggers (worth between 100 000 and
800 000MZN, see Table 8.3), 30 to 50 (usually 40)
marema
traps, weights
(stones collected locally), 'hippo fat' to waterproof the boats, a pole for
punting and a bailer. The total cost for trap i shing equipment ranged
from a minimum of 220 000MZN (US$18) for a second-hand dugout
canoe and 30 traps, to over 1 000 000MZN (US$83) for a large plank-
