Sulfate-reducing bacteria from mangrove swamps. 2. Their ecology and physiology
(Ifremer/ CNRS/ IRD/ Editions scientifiques et medicales Elsevier SAS. Tous droits reserves, 1991)Sulfate-reducing bacteria (SRB) have been enumerated and physiologically characterized in three mangrove stations along the Zuari Estuary, Goa, India. The substrates for counting were lactate, acetate, propionate, butyrate ... -
Benthic fauna of Kakinada bay and backwaters, east coast of India
(NISCAIR, New Delhi, 1991)Quantitative distribution of macro and meiofauna from Kakinada Bay and backwaters was studied. Total macrofauna abundance (no.m/2) ranged from 67 to 116 and 94 to 186 in the backwaters and near-shore environment respectively. ... -
Destruction of mangrove vegetation by Sphaeroma terebrans along Kerala coast
(Society of Fishery Technologists (India), 1991)Extent of damage causEd. by wood boring isopod crustaceans to mangrove vegetation off Kerala Coast, India has been evaluated in this study, based on a survey and monthly collections from two localities in Cochin backwaters ... -
Effect of pollution on the distribution of chaetognaths in the nearshore waters of Bombay
(NISCAIR, New Delhi, 1991)Chaetognath fauna inhabiting the polluted waters was compared with that of clean waters for evaluating the impact of pollution. Regular observations at 11 locations off Bombay coast indicated a steady decline in chaetognath ... -
Communities and coexistence of benthos in northern limb of Cochin Backwaters
(NISCAIR, New Delhi, 1991)Occurrence and coexistence of benthic communities of 9 stations in the northern limb of Cochin Backwaters (Kerala, India) where an industrial belt (mostly chemical industries) is located are studied. Polychaetes with 30 ... -
Ecology and distribution of recent planktonic foraminifera in eastern part of Arabian Sea
(NISCAIR, New Delhi, 1991)Thirty species of living planktonic foraminifera have been studied from 97 plankton tows collected from the eastern Arabian Sea with an accent on their ecological and distributional aspects. Species density is higher with ... -
Compartmental models for assessing the fishery production in the Indian Ocean
(Wiley, 1991)Compartmental models for assessing the fishery production in the Indian Ocean is discussed. The article examines the theoretical basis on which modern fishery sciences is built. The model shows that, large changes in energy ... -

Sperm density required for inducing gynogenetic haploidy in scallop Chlamys nobilis
(NISCAIR, New Delhi, 1991)Experiments conducted for standardizing sperm density for artificial insemination and inducing gynogenesis by ultra-violet rays irradiated sperms in Chlamys nobilis showed that 10:1 ratio of sperms to eggs, gave maximum ... -
Marine biosphere reserves - Need of the 21st century
(Academy of Environmental Biology, 1991)Worldwide awareness for the creation of Marine Biosphere Reserves has increased considerably due to the human depredation in many coastal areas and natural changes. Many important and unique plant and animal species have ... -
Echinoside-B from the Lakshadweep sea cucumber Actinopyga mauritiana (Quoy and Gaimard)
(NISCAIR, New Delhi, 1991)Brine-shrimp assay guided purification of the methanolic extract of the sea cucumber Actinopyga mauritiana yields echinoside-B as a major toxic constituent. The compound has been characterized based on its spectral data. -
Heterotrophic utilization of extracellular products of phytoplankton in a tropical estuary
(Cambridge University Press, 1991)Bacterial uptake of algal exudates has been estimated in a tropical estuary, Dona Paula, Goa, India, where the seasonal fluctuations in hydrographic and nutrient parameters as well as dissolved organic matter concentrations ... -
Seagrass habitat complexity and macroinvertebrate abundance in Lakshadweep coral reef lagoons, Arabian Sea
(Springer, 1991)Macrofauna of seagrass community in the five Lakshadweep atolls were studied and compared. The associated epifaunal and infaunal taxa comprising nine major taxonomic groups, showed significant differences in the total ... -
Subsurface chlorophyll maxima in the north-western Bay of Bengal
(Cambridge University Press, 1991)The depth profiles of phytoplankton pigments in the north-western Bay of Bengal are generally characterizEd. by a subsurface chlorophyll maximum. The occurrence of subsurface chlorophyll maxima is discussed in relation to ... -
