Zooplankton community of Bhayandar and Thane salt pans around Bombay
(Council of Scientific and Industrial Research, New Delhi, 1999)The zooplankton community of the salt pans of Bhayandar and Thane was studied based on the contribution of microzooplankton and meso-macrozooplankton. Population of microzooplankton was about 4 times more in Bhayandar as ... -
Marine fungi: A critique
(American Society for Microbiology, 1999)Obligate marine fungi, those which grow and sporulate exclusively under marine conditions, have received all the attention from marine mycologists. Fungi originating from freshwater, or terrestrial environment and capable ... -
Understanding marine microbes - Trends and future diections
(Indian National Science Academy, New Delhi (India), 1999)Microbes which form an integral part of any ecosystem including the marine ecosystem are represented by groups such as viruses, bacteria, fungi, diatoms, algae, protozoa etc. These being fundamental blocks of an ecosystem ... -
Distribution of hydromedusae from the exclusive economic zone of the west and east coasts of India
(Council of Scientific and Industrial Research, New Delhi, 1999)Distribution and abundance of hydromedusae from the exclusive economic zone of the west and east coasts of India is carried out based on zooplankton collections (on board FORV Sagar Sampada) during the period 1985-1990. ... -
Socioeconomic significance of mangroves for coastal people of India: A changing scenario
(Int. Soc. for Mangrove Ecosystems, Okinawa, Japan, 1999)The importance of mangrove ecosystems with particular reference to the coastal population of India has been realised recently. Natural calamities like cyclones, floods, famine, siltation and erosion are directly related ... -
A new species of the genus Sagitta (Phylum Chaetognatha) from the Agatti lagoon (Laccadive Archipelago, Indian Ocean) with comments on endemism
(Council of Scientific and Industrial Research, New Delhi, 1999)A new chaetognath Sagitta madhupratapi from the Agatti atoll, Laccadive Archipelago is described. The species belongs to the "hispida" group. Though collections were made from other atolls the species was found restricted ... -
Studies on experimental culture of a marine ciliate Fabrea salina
(Oxford and IBH, Calcutta, 1999)Studies were conducted on the culture of a marine ciliate, Fabrea salina in the laboratory condition. Three types of inert feed; commercial yeast, fermented wheat bran and fermented rise bran were tested to study their ... -
Abundance, viability and culturability of Antarctic bacteria
(Department of Ocean Development, New Delhi, India, 1999)The viability of total number of bacteria decide the mineralisation rate in any ecosystem and ultimately the fertility of the region. This study aims at establishing the extent of viability in the standing stock of the ... -
Parthenogenetic reproduction of Diaphanosoma celebensis (Crustacea: Cladocera). Effect of algae and algal density on survival, growth, life span and neonate production
(Springer, 1999)The cladoceran Diaphanosoma celebensis Stingelin is reported on for the first time from Indian waters (Mandovi Estuary, Goa). Amictic females were maintained in the laboratory (temperature 24 plus or minus 1 degrees C and ... -
Observations on feeding behaviour and survival rates in the estuarine calanoid copepods Acartia spinicauda and Heliodiaptomus cinctus (Crustacea: Copepoda: Calanoida)
(Council of Scientific and Industrial Research, New Delhi, 1999)Experiments were conducted on the calanoid copepods, Acartia spinicauda (Acartiidae) and Heliodiaptomus cinctus (Diaptomidae) in order to determine food preference and survival rates respectively. Adults of A. spinicauda ... -

New scalaranes from the nudibranch Glossodoris atromarginata and its sponge Prey
(American Chemical Society, 1999)Two new scalaranes (1 and 2) have been isolated from the dorid nudibranch Glossodoris atromarginata and its prey. The structures were determined by spectral techniques and confirmed by chemical methods. Compounds 1 and 3 ... -
Thraustochytrid fungoid protists in faecal pellets of the tunicate Pegea confoederata, their tolerance to deep-sea conditions and implication in degradation processes
(Inter-Research, 1999)During a swarm of the tunicate Pegea confoederata (salp) in the northern Arabian Sea, we examined their faecal pellets for thraustochytrid protists and bacteria to understand the role of the former in decomposition processes ... -
Immediate response of meio and macrobenthos to disturbance caused by a benthic disturber
(International Society of Offshore and Polar Engineers, Cupertino, CA (USA), 1999)The probable impact of nodule mining on benthic biota was studied by creating a benthic disturbance.
