M. Madhupratap et al., LACK OF SEASONAL AND GEOGRAPHIC-VARIATION IN MESOZOOPLANKTON BIOMASS IN THE ARABIAN SEA AND ITS STRUCTURE IN THE MIXED-LAYER, Current Science, 71(11), 1996, pp. 863-868
Mesozooplankton standing stock, abundance and composition were studied
during three seasons (summer winter and inter-monsoon) from coastal a
nd open ocean waters of the central and eastern Arabian Sea in 1994-95
, Concentrations were generally higher in the mixed layer compared to
deeper strata, A noteworthy feature was that the standing stocks and a
bundances did not vary significantly between seasons and areas, Vertic
al migrations appeared to be in a low key, In all seasons herbivores d
ominated, followed by carnivores, A few species, common in all seasons
, accounted the majority of the population The 'paradox' of the Arabia
n Sea, that zooplankton biomass remains more or less invariant, despit
e seasonally varying primary production regimes, could be explained by
a microbial loop.
