Mariculture development in Zanzibar Island, Tanzania, is limited by the
lack of appropriate technology for local conditions and cost-effective
solutions for preventing nutrient enrichment of the marine environment.
An integrated mariculture pond system (IMPS) concept originally developed
in Israel is considered as a possible model for mariculture development in
Zanzibar. An experimental IMPS has been established near the estuary of
Kiwani Creek at Makoba on the west coast of the island. Water supply is
provided by a reservoir fed by tidal fluctuations in the creek. The
experimental system consists of six ponds of 170m3 each, for the culture
of fish, shellfish and seaweed. The ponds were stocked during June and
July 1998 with 4000 fingerlings of rabbitfish (Siganus sp.) and with different
species of shellfish and seaweed. Water quality parameters in the ponds,
such as temperature, oxygen and salinity, were kept within acceptable
limits by a periodic water supply. Fish were fed daily with a diet developed
for this project. Preliminary results indicate reasonable growth of the fish
but also mortality of fish, shellfish and seaweed. |
