N. Ramaiah et Vr. Nair, DISTRIBUTION AND ABUNDANCE OF COPEPODS IN THE POLLUTION GRADIENT ZONES OF BOMBAY HARBOR THANA CREEK BASSEIN CREEK, WEST-COAST OF INDIA, Indian journal of marine sciences, 26(1), 1997, pp. 20-25
Forty six species of copepods were identified, of which, 40 belonged t
o Calanoida with an overall dominance of Acartiidae. Acartia spinicaud
a, A. centrura and Centropages dorsispinatus were the common species t
hroughout the year at all locations. Eucalanus subcrassus and Paracala
nus aculeatus were more abundant in the outer zone, while A. tropica w
as very common in the interior region. Hyposaline species, Pseudodiapt
omus binghami malayalus was recorded from the interior locations parti
cularly during the monsoon months (June-September). Diversity indices
(Shannon-Weaver's H' and Margalef's D) were higher in the outer coasta
l waters than in creek zone indicating lethal or sublethal effects of
industrial and domestic wastes on the general faunistic composition as
well as water quality of the creek stations.
