Studies on the Algal Distribution in Various Salt-Pans of Kanyakumari District, Tamilnadu, India

摘要

Aquaculture is a popular food producing sector with the target of farming useful organisms in water for food production. Microalgae are one of the many organisms cultured as live feed recently in India. Majority of the algal species can adopt themselves physiologically to a very wide range of salinity. Algae are efficient bio accumulators of inorganic nutrients. Microalgae grow efficiently in a medium having a variety of substances and nutrients in low concentrations instead of a single nutrient in high concentration. Recently, the utilization of saltworks for the production of artemia has increased considerably as it is an indispensable source of food for a number of fish and shrimp larvae. Salt-pans have a ruling temperature of around 24° to 35°C and a temperature of 25° to 30°C is sufficiently favoured to have an increase in biomass content of microalgae. The high nutritive value and adaptability to various environment with a wide range of pH, nutrients and other physical conditions make the microalgae an ideal feed in marine aquaculture enterprise and also a supplement item in human and animal nutrition. The cultivation of these algae with a proper scientific know-how, will improve not only the hatchery need of culture of fishes and shrimps, but also develop the socio-economic status of the coastal people. So, a study was conducted and it unfolds the distribution of algae in different stages of various salt-pans.
