(Society of Biosciences, Muzaffarnagar (India), 1997)Acute toxicity (LC sub(50)) and effect of some petroleum hydrocarbons (Toluene, Quinoline, Pyridine and Naphthalene) on the metabolic index (oxygen consumption rate) of an estuarine fish. Etroplus suratensis is reported. ... -
Toxic effects of coastal and marine plant extracts on mosquito larvae
(Walter de Gruyter, Berlin, 1997)Petroleum-ether and chloroform soluble fractions of methanolic extracts of mangrove/plants (Derris heterophylla, Salvadora persica, Sonneratia caseolaris, Clerodendron inerme), seaweeds (Acanthophora muscoides, Microdictyon ... -
Molecular evidence for cryptic species among the Antarctic fish Trematomus bernacchii and Trematomus hansoni
(Cambridge University Press, 1997)The notothenid species Trematomus bernacchii has previously been shown, by allozyme analysis, to be a complex of two cryptic species, one of which being more closely related to T. hansoni than to the other T. bernacchii ... -
An overview of the planktonic foraminiferal fauna in waters off the Kerala Coast, south-west India during summer
(Marine Biological Association of India, 1997)Twentyeight species of planktonic Foraminifera are recorded from 46 plankton samples collected from 27 stations of 5 traverses along the Kerala Coast. The mean abundance of total foraminiferal sepcimens of all the stations ... -
Cochin backwaters: A sad story of manipulation
(The Royal Swedish Academy of Sciences, 1997)Cochin backwaters, along the south west coast of India have been altered several times for various causes and the system has undergone tremendous environmental changes as a consequence developmental activities and associated ... -
Effect of holothurian and zoanthid extracts on growth of some bacterial and diatom species
(NISCAIR, CSIR, 1997)The antifouling properties of the extracts from two zoanthids, viz. Zoanthus sp, Protopalythoa sp and one holothurian species, viz. Holothuria leucospilota occurring in the coastal waters off Goa were tested against 5 ... -
Recent advances in marine microbiology: the Indian scenario
(Springer, 1997)Great strides have been made in understanding the microbes of the seas around India, and these include both mycological and bacteriological aspects, covering near, offshore, and deep-sea waters. In mycology, the role of ... -
The ecology and distribution of alcyonaceans at Mandapam (Palk Bay, Gulf of Mannar), South India
(Bombay Natural History Society, 1997)New distribution records for 27 species of Alcyonaceans are given. These include major genera Sinularia (12 spp.), Lobophytum (7 spp.), Sarcophyton (6 spp.), Dampia (1 sp.) and Nephthya (1 sp.). The factors that influence ... -
Starvation threshold of Balanus amphitrite larvae in relation to temperature
(US Office of Naval Research, 1997)Energy content in the non-feeding (lecithotrophic) cyprid larvae of B. amphitrite plays an important role in determining its metamorphic characteristics. In this context it is important to understand the energy transformed ... -
Carrying capacity of coral reefs
(M.S. Swaminathan Res. Found., Chennai (India), 1997)The sustainable yield of a commercially exploited fishery is assessed by the biological and environmental factors (including fishing effort). These parameters with a reef are vastly diverse-size, location, species diversity, ... -
Crowning corals
(NISCAIR, CSIR, 1997)Biodiversity of coral reefs is responsible for productivity in the sea and these coral reefs are built mainly by corals containing a calcium-carbonate skeleton. The reef building corals are the hermotypic corals harbouring ... -
Distribution and abundance of copepods in the pollution gradient zones of Bombay Harbour-Thana Creek-Bassein Creek, west coast of India

Marine sponges: a potential source of eco-friendly antifouling compounds
(US Office of Naval Research, 1997)Antifouling protocols rely to a great extent on the application of paints or altering substratum characteristics. It has been evidence that commercial antifouling paints which are currently in use employ toxic biocides. ... -
Role of salinity on food conversion efficiency and growth in juvenile penaeid shrimp Metapenaeus dobsoni (Crustacea/Arthropoda)
(NISCAIR, CSIR, 1997)Growth parameters of juvenile Metapenaeus dobsoni, fed with fresh squid meat were estimated in 5, 15, 25 and 35 ppt salinities for 4 weeks. Although no significant differences were noticed in food ingestion rates, higher ...
