Growth of hatchery raised banana shrimp Penaeus merguiensis (de Man) (Crustacea: Decapoda) juveniles under different salinity
(NISCAIR, CSIR, 2000)In order to optimise the conditions for improved production of the banana shrimp Penaeus merguiensis in the farms, effect of salinity on growth and survival was studied for 4 weeks using hatchery reared juveniles. Survival ... -
Basement configuration of Visakhapatnam - Paradip continental margin from inversion of magnetic anomalies
(NISCAIR, CSIR, 2000)Inversion of magnetic data was carried out on 40 profiles collected across the continental margin of Visakhapatnam, Andhra Pradesh, India at a spacing of about 10 km and magnetic basement map for this region is prepared. ... -
Foraminiferal study from Kharo Creek, Kachchh (Gujarat), north west coast of India
(NISCAIR, CSIR, 2000)A total of seven surface sediment samples collected within 4 to 13.5 m water depth below chart datum from Kharo Creek, Gujarat, India were studied for their foraminiferal content. The study revealed 47 foraminiferal species ... -
Phosphate solubilizing bacteria around Indian peninsula
(NISCAIR, CSIR, 2000)The occurrence and physiological characteristics of marine phosphate solubilizing bacteria (PSB) around the Indian peninsula were studied. A higher percentage of phosphate solubilizing bacteria was seen in the islands and ... -
Pollution monitoring of coastal and estuarine areas: 1. Bacterial indicators along the south Gujarat Coast
(NISCAIR, CSIR, 2000)A study was undertaken to assess the validity of enteric and supplemental bacterial indicators along the 115-km length of the south Gujarat region (India). Enteric organisms like Proteus and Klebsiella, Escherichia coli, ... -
Further obsrvations on a newly located prawn fishery off Saurashtra coast

Isolation of peridininol, an anti-spasmodic carotenoid pigment, from Zoanthus sp.
(AP Akademi of Sciences, India, 2005)A C37 carotenoid pigment, peridininol, isolated from a marine Zoanthus sp. exhibited promising anti-spasmodic activity against nicotine and serotonin in in vitro studies using guinea pig ileum. Its purification and structure ... -
Air-sea exchanges of materials in the Indian Ocean: Concerns and strategies
(AP Akademi of Sciences, India, 2004)Exchanges of materials at the air-sea interface are linked to earth's heat budget and the natural balance is being increasingly affected by human activities. Three major issues of national concern with respect to changes ... -
Submarine methane hydrates - Potential fuel resource of the 21st century
(AP Akademi of Sciences, India, 2001)Natural methane hydrates have a potential of being an alternate fuel resource. They occur worldwide in the sediments of continental margins and in polar regions in association with permafrost. Methane hydrates are ice-like ... -
Effect of oxygen manipulations on benthic foraminifera: A preliminary experiment
(NISCAIR, CSIR, 2006)Three sediment cores were collected at 50 m water depth on the west coast of India, off Ratnagiri, and were subjected to oxygen manipulations maintaining natural temperature and salinity. The objective was to understand ... -
