Barotolerance of fungi isolated from deep-sea sediments of the Indian Ocean
(Inter-Research, 1998)Two species of filamentous fungi, Aspergillus ustus (Bain.) Thoms and Church and Graphium sp., were isolated from calcareous animal shells at depths of 860 m in the Arabian Sea and 965 m in the Bay of Bengal. Laboratory ... -
Distribution of scolecithricidae (Copepoda: Calanoida) in the Indian Ocean
(Intergovernmental Oceanographic Commission, 1998)Ecology and zoogeography of the frequently occurring and widely distributed planktonic copepods collected during the International Indian Ocean Expedition, Scolecithrix danae, Scolecithricella bradyi, S. tenuiserrata, S. ... -
Severe fish mortality associated with 'red tide' observed in the sea off Cochin
(Current Science Association, 1998)Severe fish mortality associated with the "red tide" phenomenon caused by Noctiluca blooms was observed in the sea off Cochin, Kerala, India at depths less than 40 m. The dead fish, almost entirely comprised of the threadfin ... -
Shrimp farming in estuarine environment: Points to ponder
(Rajiv Gandhi Centre for Aquaculture, Subramaniyapuram (India), 1998)The capture fishery resources have almost reached a sustainable yield and the production can only be supplemented through culture fishery practices. This is particularly true in case of marine shrimps. The annual foreign ... -
Bacterial flora of pond reared Penaeus indicus (Milne Edwards)
(Oxford and IBH, 1998)The population size, generic diversity and potential to produce hydrolytic enzymes of heterotrophic bacteria associated with pond reared Penaeus indicus was worked out following standard bacteriological procedures. ... -
Ecobiological assessment of a freshwater lake at Schirmacher Oasis, East Antarctica, with reference to human activities
(Current Science Association, 1998)The scale and magnitude of probable impact of human activities over a decade (1983-1994) on the freshwater lake Priyadarshini, at Schirmacher Oasis, East Antarctica, was assessed through an ecological study conducted over ... -
Diseases and parasites of laboratory reared and wild population of banded pearl spot Etroplus suratensis (Cichlidae) in Goa
(NISCAIR, CSIR, 1998)Banded Pearl spot Etroplus suratensis, the inhabitant of coastal backwaters and lagoons is one among the few finfish species identified for brackishwater farming. Common diseases and parasites from the wild population of ... -
Seasonal variation of major elements (Ca, Mg) and trace metals (Fe, Cu, Zn, Mn) and cultured mussel Perna viridis L. and seawater in the Dona Paula Bay, Goa
(NISCAIR, CSIR, 1998)The major elements and trace metals were analysed from nussel tissue and the seawater taken from three depths (0, 5 and 9 meters) from the culture site. Range of variation in Ca, Mg, Fe, Cu, Zn and Mn were 226-399; 708-1329; ... -
Spatial variation in meiofaunal abundance of some coralline beaches of Mauritius
(International Society for Tropical Ecology, 1998)Abundance of metazoan meiofauna was examined at 12 coralline sandy beaches of Mauritius island during September-October, 1987. Beach sediment comprised of moderately well sorted sand particles (Mz=0.53-2.80 phi ; x=1.70). ... -
