Abstract—In collaboration with local stakeholders, Frontier-Tanzania is collecting biophysical
information to facilitate effective management initiatives for Misali Island, where marine
resource management is currently limited to a 1.4-km2 non-extraction zone within a 21.6-km2
conservation area. In the study reported here, the extraction and non-extraction zones at Misali
Island with similar substrata were compared. Data analysis showed a significant disassociation
in both abundance and mean length patterns of fish families found in each zone. Further analysis
using t-tests on individual families showed that some groups were significantly more abundant
in either zone, but without significant differences of mean lengths.
Fish family abundance and length records within and outside the non-extraction zone are
likely to be affected to varying degrees by a combination of four main factors, including (i)
direct fishing effects through target species, (ii) indirect fishing effects through catch of predatory
species, (iii) habitat-dependence and (iv) effectiveness of the non-extraction zone.
