Adaptations in Phytoplankton to Changing Conditions in Tropical Estuaries
(Indian Association for Limnology and Oceanography, 1980)
Experimental studies on phytoplankton organisms from Cochin backwaters (a tropical estuary) have shown that many algal forms are adapted to changing conditions of salinity, light and nutrients. Photosynthesis in 12 species ...
Contribution of Phytoplankton Photosynthesis to a Mangrove Ecosystem
(Indian Association for Limnology and Oceanography, 1980)
Primary production in a fringing mangrove ecosystem was measured using two techniques. The first estimated gross oxygen production and community metabolism based on the diel difference in dissolved oxygen concentrations. ...
Experimental studies on Urea Degradation in Seawater
(Indian Association for Limnology and Oceanography, 1980)
The rate of urea degradation in seawater was studied under various conditions and the kinetics of urea degradation was evaluated. Urea decomposition experiments showed that the rates and quantity of ammonium oxidation were ...
Benthic Studies in Goa Estuaries. Part 3. Annual Cycle of Macrofaunal Distribution, Production and Trophic Relations
(CSIR-NISCAIR, 1980)
Macrobenthos in Mandovi, Cumbarjua canal and Zuari estuaries, a physically interconnected tropical estuarine system which undergoes large seasonal changes in salinity distribution due to heavy monsoonal precipitation, is ...
The Protozoan Associates of some Crustaceans
(Indian Association for Limnology and Oceanography, 1980)
Protozoan associates found on the estuarine shrimp Metapenaeus monoceros (Fabricius) and the tanaidacean Apseudes chilkensis (Chilton) from Cochin backwaters have been described. A peritrich ciliate Zoothamnium rigidum ...
Primary Production in the Bay of Bengal during Southwest Monsoon of 1978
(Indian Association for Limnology and Oceanography, 1980)
Measurements of primary production, chlorophyll a and particulate organic carbon were made at 33, 43 and 44 stations respectively during August-September of 1978. The average surface production, chlorophyll a and particulate ...
Seasonal Variations in Secondary Production of the Mandovi-Zuari Estuarine System of Goa
(CSIR-NISCAIR, 1980)
Mean rates of secondary production in the Mandovi, Zuari and Cumbarjua canal, Goa, India were 16.9, 35.9 and 32.4 mg C/m2/day respectively. The general hydrographic conditions of the Zuari were responsible for the higher ...
Production and Associations of Zooplankton in Estuarine and Nearshore Waters of Goa
(CSIR-NISCAIR, 1980)
Zooplankton production in the Zuari and Mandovi estuaries indicated 2 peaks-one in November and another in March/April. In the nearshore waters very high value of zooplankton biomass was observed in April associated with ...
Fungal infection in the tiger prawn (Penaeus monodon) and in other crustaceans from the Cochin Backwaters
(Indian Association for Limnology and Oceanography, 1980)
Infection of the two species of fungi (Phycomycetes) in the tiger prawn (Penaeus monodon) and three species in amphipods (Gammarus sp.) and tanaeidaceans (Apseudes sp.) was observed. Of the two pathogens in the shrimp, ...
