created land bridges or shallow continetal shelf which allowed animals to go through
(Moreau and Pakenham 1941).
During the survey and when conducting foot transects it was observed that there were
many feral dogs in the forest. Some appeared to be out of control. The presence of
feral dogs in the forest affects the pristine nature of the forest and needs to be
controlled. There is also a potential danger of spread of rabies due to the presence of
dogs and many bats that act as vectors of rabies.

4.2.12 Fish
Five fish families of fresh or brackish water recoded at the study area. In the study
area there is no permanent river but there are several ponds and swamps. Nine villages
surrounding Ngezi are Msuka, Kijijini, Tondooni, Mkia wa Ng’ombe, Jiwe moja,
Makangale, Bandari kuu, Kipangani, and Gombani. Most of the information on fish
and fisheries in Pemba waters is in many cases similar to what was reported in Jozani
National Park (Nahonyo et al. 2002).
4.2.12.1 Fisheries resources
Fisheries resources found on Pemba waters include fish, prawns, sea cucumbers,
seaweeds and lobsters. These are mainly exported but finfishes are used for local
consumption. All these resources are also available at villages around the Ngezi
forest. Other marine resources like prawns, lobsters, and seashells have declined in
recent years. In the past decade these resources were collected in substantial amounts
in the inter-tidal zones but nowadays one must do SCUBA diving in deep sea to
collect them. Other resources like Sea-shells (bivalve, mollusks and cockles) are used
domestically since their production is low (FAO/Department of Environment
Zanzibar, 1999).
4.2.12.2 Fish species occurrence, endemism and diversity in Ngezi
Ngezi forest is found northern part of Pemba Island. Pemba as part of Zanzibar in
region No.51 FAO of the global fisheries sector. It has a number of species
(Carcasson, 1977; Bianch, 1985), which are common and distributed throughout the
region (FAO, 1984a). In Ngezi there are at least 57 fish families (Appendix 7a and 7b)
and not less than 100 fish species (Appendix I and II). None of the families are
endemic to Zanzibar. Most of the fishes obtained in this area are found elsewhere in
the region according to FAO (1984a, 1984b, 1984c, 1984d; Bianch, 1985).
