| Abstract: | Impact of soda ash industry effluent on
macroalgal distribution, abundance, species composition, diversity and standing
stock was studied, in situ, on tropical seaweeds of Arabian Sea,
Gujarat. Comparatively, less number of species and different pattern of
macroalgal assemblages were recorded at the discharge point, while transects
distance from discharge point showed more number of species, luxuriant growth
and well developed macroalgae. Factors responsible for structuring macroalgal
communities were distance from the effluent discharge point, degree of tidal
flushing and tolerance capacity of the macroalgae to the effluent. Caulerpa
sertulariodes and Champia somalensis were most resistant and had a
preference for soda ash industry effluent as they were recorded only near the
effluent discharge point. Codium dwarkense and Dictyota bartayresiana
also had similar characteristics as they were recorded only 1 km away from
the effluent discharge point. Caulerpa racemosa, Chamaedoris auriculata,
Valoniopsis pachynem and Stoechosperumum marginatum were most
sensitive as they were recorded only from the control site. Ulva lactuca,
Caulerpa taxifolia, Gracilaria corticata and Laurencia cruciata were
recorded from all sampling sites indicating their adaptability to varying
degrees of pollution. |
