Utilization of natural byproducts for the cultivation of blue-green algae
The work of Allen, Gross and Harveyo has
proved t he importance of trace elements as
essential auxiliaries of the major nutrients, Ca,
K, Mg, Na, Cl, S, P and N in the metabolism
of planktonic organisms including diatoms. In
their studies extracts of Ulva and Fucus, unsuspected
as sources of trace elements, were
actually found to induce the growth in cultures
of diatoms in artificial sea-water
Water - soluble constituents of Gracilaria lichenoides
The seasonal variation in the water- soluble constituents of Gracilaria Iichenoides collected from. Palk Bay has been studied. An economic method has been worked out for the extraction of agar from the seaweed
Bacteriological standards for fresh fishery products
The primary objective of every
commercial fishery enterprise тАвwill be to
deliver to the consumer fish products in
the best possible condition at the right
price and in the right packing. Quality
retention is absolutely essential
especially in the case of fi sh and fish
products, as consumer preference and
ultimate image of the products will
largely depend on qualit
Chemical composition of lagoon muds
It has been shown in earlier communications (Krishna Pillai, 1954, -1955) that the conditions existing in salt-water lagoons bear no similarity to those found either in open sea or in fresh-waters and that productivity in the lagoons is controlled by factors that difrer in nature and degree of in.fluence from those of the natural environment
Growth requirements of a halophilic blue-green alga, Phormidium Tenue (menegh).
In order to account for the negligible growth of algae observed in the saline lagoons at Mandapam a complete knowledge of the normal nutritional and general hysiological factors controlling the growth of at least the dominant species of the algal association is necessary. This information will also have applied significance in the maintenance of adequate algal growth, a prerequisite for successful fish culture in these lagoons, regardless of whether or not the fish grown feeds directly on the algae
Ascending (paper) chromatography of sugars by the multiple development technique
In the present communication results obtained by extending the technique of Jeans et al. to the resolution of a mixture
containing five sngars (lactose, maltose, dextrose, galactose and arabinose each sugar at 1 per cent level) are give
Marine environment and pollution
Marine pollution and its impact on the living resources
is one of the topics discussed all over the world today. In the broadest sense, the term pollution refers to any change in the natural quality of the environment brought about by chemical, physical or biological agents. In practice however, pollution is the result of human activity, either direct, indirect or incidental

Marine pollution in the coastal waters of India
The environmental pressure due to pollution inputs and also due to
human interference on tlte ecosystem are on the increase. Information
on marine environmental damage from various sources of
pollution and human interference becomes an obvious necessity to
evaluate the present level of pollution as ivell as to understand the
impact on living resources
