Description 349-359
Present study consists the species
diversity, abundance and community structure of ichthyofauna in the seagrass
meadow of Minicoy Atoll, Lakshadweep
Islands. Two hundred and
three species of fishes were recorded during the study, from four stations in
the Atoll. They belonged to 2 classes, 11orders, 43 families and 93 genera. Six
species belonged to the class Chondreichthyes and 197 species to Osteichthyes. Family
Pomacentridae showed maximum abundance of species (22%). Station I, having
close proximity to the coral reefs, observed the maximum number of families
(37) and species (129) and that with minimum number was in station II (23
families and 52 species). Bray-Curtis similarity
plot showed a similarity range of 22 to 52%, seasonally. Station I showed
highest Shannon-Wiener diversity index (H’log2) (4.22) during August
and the lowest (2.91) during June. Stations I and III showed comparatively
higher abundance and diversity of fishes. Variability in seagrass habitat
structure and the interaction with coral reefs influenced the species
composition and diversity of fishes in Minicoy Atoll. The findings of the
present investigation can be used as baseline information for the fishery resource
management of the region.
