Biochemical studies on some Tropical Esturine Zooplankton Species

Madhu Pratap,M; Haridas,P; Venugopal,P (Indian Journal of Marine sciences, March 22, 1979)

[+]

Abstract:

Percentages of protein, carbohydrate and lipid which form the major biochemical constituents of 10 species of zooplankton from Cochin backwaters were estimated . Protein invariably formed the major constituent in terms of dry weight. Carbohydrate content was in general very poor . Both protein and lipid were low for organisms with higher water content and did not show any reciprocal relationship . The results in general supported the view that protein may function as a metabolic reserve in zooplankton and that the availability of a constant supply of food may render large amount of lipid storage unnecessary in tropical zooplankton.

Incidence of Red Water Along South Kerala Coast

Venugopal,P; Haridas,P; Madhu Pratap,M; Rao,T S S (Indian Journal of Marine sciences, January 12, 1979)

[+]

Abstract:

Incidence of red water along the Kerala coast at 2 localities, off Quilon and Cochin, in August 1976 and 1977 is reported. High concentrations of Noctiluca miliaris (up to 7.71 x 105/m3 in 1977) are associated with these occurrences. They completely dominate the plankton community contributing > 90 % of the numbers. High production of diatoms initiated by nutrient-rich and fairly high saline upwelled waters appears to cause the bloom of the dinoflagellate Noctiluca

Toxicity of Effluent from a Titanium Dioxide Factory on some Marine Animals

Madhu Pratap,M; Haridas,P; Gopalakrishnan,T C; Sankaranarayanan,V N; Gopala Menon,P (Indian Journal of Marine sciences, October 12, 1978)

[+]

Abstract:

Toxicity of effluent from a titanium dioxide factory containing sulphuric acid residue with soluble iron metallic salts and insoluble material such as silica, etc. on fishes, decapods and molluscs was studied. The effluent caused changes in pH and oxygen depletion of the sea water. Sublethal effects of the precipitate of ferrous salts were also studied. Dilutions of effluent up to 1:150 were LC100 for all organisms used while 1:200 dilution was LC50 for fishes at 36 hr and for other organisms at 48 hr. But death of organisms at this concentration was caused by pH changes and oxygen depletion and did not account for the effects of the precipitate. Below this level precipitation started soon after mixing with sea water causing death of organisms by choking their gills and siphons. Dilutions,< 1:1000 were 96 hr LCO.

Comparative Studies on the Abundance of Zooplankton in the Surrounding Sea & Lagoons in the Lakshadweep

Madhu Pratap,M; Wafar,M V M; Haridas,P; Narayanan,B; Gopala Menon,P; Sivadas,P (Indian Journal of Marine sciences, September 17, 1977)

[+]

Abstract:

Composition and distribution of various groups and species of zooplankton at Kavaratti, Agatti and Suhelipar atolls of the Lakshadweep group of islands are reported . Higher biomass and diversity occur in the sea surrounding atolls compared to lagoons . Copepoda forms the dominant component of zooplankton . Zooplankton washed across the reef into the lagoon may be serving as food to the reef community . No fauna endemic to lagoons are encountered.
