of alternative livelihood, continue to fish on Friday night.
It is also a taboo for Muslim fishers, who have been fasting,
to dive for octopus during the holy Ramadhani month. Similarly,
it is a taboo for some fishers to fish during `mwaka-kogwa',
wedding ceremonies, election days and during neap tides.
Furthermore, in early times, there was a one-day ceremony during
male circumcision during which there was no fishing.
10.Meetingwithoneperson
Some fishers cancel fishing activities if, when going out to fish or
check nets/traps, they meet with one person. This is believed as a
bad omen on that day as nothing wil be caught. On the contrary,
it is considered a lucky sign to meet with two or more people when
a fisher goes out fishing.

Even magical power has
a role, too
Fisheries in coastal communities have long been associated
with innumerable magical practices. Some fishers believe that,
in order to catch more fish, a talisman must be tied to the
fishing gear or vessels, and/or a prayer must be said in order
to give fishermen confidence in the face of a wide range of
hazards and threats.
A traditional healer should be consulted to find the best time
and day to leave home and the best direction for fishing and
camping. In addition, some fishers believe that a big tree found
along the coast is a home of evil spirits, so a special prayer must
be said before cutting down the tree for vessel construction to
avoid misfortune. In the absence of traditional healers the
number of fishing vessels is greatly reduced and thus fishing
pressure is reduced and fishing habitats are protected.



A roadmap to preserve customs, taboos, beliefs
PolicyRecommendations
Unless steps are taken to preserve and utilise indigenous
knowledge, there is a risk that its role in protecting fish
stocks and coastal habitats wil be further eroded.
Here are recommendations from which seek to preserve
the role of indigenous knowledge in the management of
fish stocks and coastal habitats along the Tanzanian coast.
