The larvae of decapods and fishes of Amba estuary, Maharashtra
(Fishery Survey of India, 2004)Larvae of fishes and decapods found in zooplankton collections from two stations (Mankule and Patalganga) in Amba estuary adjoining Mumbai harbour were studied during 1989-90 covering three seasons. The percentage contributions ... -
Nitrogen uptake by size-fractionated plankton in permanently well-mixed temperate coastal waters
(Oxford University Press, 2004)Nitrogen uptake by net- (15-200 mu m), nano- (1-15 mu m) and picoplankton (less than 1 mu m) was measured over seasonal cycles at two stations with different patterns of biological and chemical cycles in the Morlaix Bay ... -
Nitrogen and phosphorus requirements of an Alexandrium minutum bloom in the Penze' Estuary, France
(American Society of Limnology and Oceanography, 2004)During an intense (up to 33 x 10 sup(6) cells L sup(-1)) Alexandrium minutum bloom in the Penze estuary (France), total NO sub(3), NH sub(4), and PO sub(4) requirements of the bloom were, respectively, 184, 25, and 20 mu ... -
Unseen and unsung heroes: The microbes
(WWF for Nature-India, 2004)Fungi are larger microorganisms and their bodies are mostly filamentous, the filaments being called hyphae. It is now believed that fungi evolved from an ancestor that was also common to animals. The width of the fungal ... -
Environmental impact assessment - A management tool for conservation of large marine ecosystems
(Fishery Survey of India, 2004)Coastal development includes a variety of activities which will have significant impact on marine ecosystem especially in the shallow nearshore areas. The stress relevant to coastal zone emerge from hinterland activities, ... -
Vertical migratory rhythms of benthic diatoms in a tropical intertidal sand flat: Influence of irradiance and tides
(Springer, 2004)Vertical migratory behavior of benthic diatoms is one of the adaptive strategies employed for a life in intertidal habitats. Irradiance and tides are considered to be the key factors governing vertical migration. Experiments ... -
Distribution of baroduric, psychrotrophic and culturable nitrifying and denitrifying bacteria in the Central Indian Basin
(National Institute of Ocean Technology, 2004)The abundance of baroduric, culturable nitrifying and denitrifying bacteria in the deep-sea cores of Central Indian Basin (CIB) at ca 5000 m depth was investigated. Analysis of 8 cores, sampled between 10 degrees 00 minutes ... -
Identification, isolation and characterization of active compounds from the Indian green mussels to develop drugs
(National Institute of Oceanography, India, 2004)Recent studies showed that green mussel is not only an inexpensive source of protein for human consumption but also possess some complex bioactive compounds that have tremendous potential in medicine. Two compounds identified, ... -
Benthos and demersal fishery resources assessment in the shelf region of Indian coast
(Fishery Survey of India, 2004)The potential of exploitable demersal fishery resources is estimated to be 0.4 million metric tones per year (m.m.t.y.) and 0.25 m.m.t.y. respectively based on benthic biomass production and the food pyramid concept, in ... -
Effect of soft coral extracts on isolated tissues
(National Institute of Ocean Technology, 2004)Methanolic extracts of eleven species of soft corals collected from Lakshwadeep islands in the Arabian Sea and Mandapam in the east coast of India were tested for their antispasmodic, antiarrhythmic and oxytocic activity ... -
Studies on the life span, reproduction, tissue biochemistry and diesel oil toxicity in the estuarine cladocera Diaphanosoma celebensis
(National Institute of Ocean Technology, 2004)Diaphanosoma celebensis Stingelin is a typical estuarine cladocera, reported for the first time in India from the Mandovi estuary of Goa, India. The results of the study made on the laboratory reared specimens of this ... -
Mangroves - Nursery for fishes
(WWF for Nature-India, 2004)Mangrove habitats are of a great ecological and socio-economic significance. Goa exhibits fringing mangroves comprising of 15 species. Shizophora mucronata, Avicennia officinalis, Sonneretia alba, S. caseolaris, Exoecaria ... -
Diversity of nitrite reductase genes (nirS) in the denitrifying water column of the coastal Arabian Sea
(Inter-Research, 2004)Denitrification often occurs in the water column, underlying zones of intense productivity and decomposition in upwelling regions. In the denitrifying zone off the southwest coast of India, high concentrations of nitrite ... -
Enhanced production of polyunsaturated fatty acid docosahexaenoic acid by thraustochytrid protists
(Springer, 2004)The polyunsaturated fatty acid docosahexaenoic acid (DHA) is an important requirement in the human diet. It is also essential in the nutrition of crustaceans and aquaculture animals. Of the sources available for commercial ... -
Biological productivity and potential resources of the exclusive economic zone (EEZ) of India
(Fishery Survey of India, 2004)An assessment of the biological production and the potential fishery resources has been made based on the data collected over a period of 15 years (1976-1991). The entire Exclusive Economic Zone (EEZ), measuring 2.02 million ... -
Culturable epibacteria of the marine sponge Ircinia fusca: Temporal variations and their possible role in the epibacterial defense of the host
(Inter-Research, 2004)The influence of environmental changes on the epibacterial population of the marine sponge Ircinia fusca (Carter) was evaluated by using a bacterial culture-based approach. Sponge surface-associated bacteria were isolated, ... -
Biological active anthraquinone analogs from the fungus Eurotium sp.
(National Institute of Ocean Technology, 2004)Four known anthraquinones: Physcion, fluoroglaucin, catenarin and alaternin as well as a cyclic dipeptide with a triprenylated indole moiety, echinulin were purified from acetone extract of the mycelial mats of the fungus ... -
The impact of food type, temperature and starvation on larval development of Balanus amphitrite Darwin (Cirripedia: Thoracica)
(Elsevier, 2004)The impact of diatom food species (Chaetoceros calcitrans and Skeletonema costatum), temperature and starvation on the larval development of Balanus amphitrite was evaluated. Starvation threshold levels for different ages ... -
Indian satellite IRS-P4 (OCEANSAT). Monitoring algal blooms in the Arabian Sea
(UNESCO, 2004)While there have been a number of reports on occurrences of algal blooms in the coastal waters of India, the observation on large scale Noctiluca bloom during FORV Sagar Sampada cruises (years 2003 and 2004), forms the ... -
