Adult Artemia as food for juvenile prawns
Royan, J.P.; Sumitra-Vijayaraghavan; Krishnakumari, L. (Indian Association for Limnology and Oceanography, 1987)Feeding experiments on three commercially important shrimps Penaues indicus, Metapenaeus dobsoni and M. monoceros were carried out using adult Artemia as feed. Good growth and food conversion efficiencies were recorded at ... -

Assessment of cyst production potential of a natural population of brine shrimp Artemia
Royan, J.P.; Sumitra-Vijayaraghavan; Krishnakumari, L. (NISCAIR, New Delhi, 1991)Studies on a natural population of Artemia in the salterns of Jamnagar indicated that the population is parthenogenetic. These shrimps reach a maximum size of 9 mm. Number of cysts per brood varies from 10-32. Adults form ... -
Biochemical Changes and Energy content of the Mangrove, Rhizophora Mucronata, Leaves during Decomposition
Sumitra-Vijayaraghavan; Ramadhas, V.; Krishnakumari, L.; Royan, J.P. (CSIR-NISCAIR, 1980)Decomposition of Rhizophora mucronata leaves both in the laboratory and in the field resulted in the loss of organic carbon and ash and increase in total nitrogen, organic matter, protein and caloric content. In the ... -
Biological productivity of coastal waters of India - from Dabhol to Tuticorin
Qasim, S.Z.; Wafar, M.V.M.; Sumitra-Vijayaraghavan; Royan, J.P.; Krishnakumari, L. (CSIR-NISCAIR, 1978) -
Biomass production of Artemia in air-water-lift raceway system
Royan, J.P.; Vijayaraghavan, S.; Krishnakumari, L. (National Institute of Oceanography, India, 1990) -
Caloric Densities of Ingested Food of Etroplus Suratensis (Bloch) Grown in a Culture Pond
Sumitra-Vijayaraghavan; Krishnakumari, L.; Dhawan, R.M.; Royan, J.P. (CSIR-NISCAIR, 1981)Analyses of stomach contents of E.suratensis indicated that it is principally a phytoplankton-detritus feeder. Biochemical analyses of the ingested food showed that of the total consumed food, 44% was contributed by ash ... -
Changes in biochemical composition and energy utilization in developmental stages of the mole crab, Emerita holthuisi Sankolli
Sumitra-Vijayaraghavan; Wafar, M.V.M.; Royan, J.P. (Indian Association for Limnology and Oceanography, 1975) -
Comparison live adult Artemia and squid meat on the growth of Penaeid shrimp Metapenaeus dobsoni (Miers)
Nair, S.R.S.; Achuthankutty, C.T.; Royan, J.P. (Indian National Science Academy, 1995)An experiment lasting 14 weeks was conducted to compare the efficiency of live adult Artemia with fresh squid meat on growth of penaeid shrimp Metapenaeus dobsoni. The shrimps were found actively feeding on live Artemia ... -
Cyst quality and hatching in parthenogenetic brine shrimp, Artemia
Royan, J.P.; Sumitra-Vijayaraghavan; Krishnakumari, L.; Ramaiah, N. (CSIR-NISCAIR, 1987)Data on cyst size, naupliar size, biochemical constituents (carbohydrate, protein and lipid) and hatching characteristics (in relation to temperature, salinity, different glycerol concentrations and antibiotics) of Artemia ... -
Decapsulated Brine Shrimp Cysts - An Ideal feed for Shrimps in Aquaculture
Royan, J.P. (CSIR-NISCAIR, 1980)Feeding experiments have been carried out with Metapenaeus monoceros using different stages of Artemia salina as feed. The importance of using decapsulated cysts to obtain greater food conversion efficiency has been indicated -

Sumitra-Vijayaraghavan; Royan, J.P.; Rao, T.S.S. (CSIR-NISCAIR, 1982)Growth efficiency (K sub(1) and K sub(2)) increased from 7 to 15% feeding levels, Maximum water content was recorded in starved prawns and the minimum at 20% feeding level On theoretical basis, average daily feeding level ... -
Energy content of suspended detritus from Arabian Sea
Krishnakumari, L.; Sumitra-Vijayaraghavan; Royan, J.P. (NISCAIR, New Delhi, 1991)Energy components of suspended matter included phytoplankton, zooplankton and detritus inclusive of microorganisms adsorbed to detritus. Of these, detritus contributed most of the energy (98%). The average caloric content ... -
