Evaluation of radiological hazards due to natural radionuclide in rocks and the dependence of radioactivity on the mineralogy of rocks in Udupi district on the south west coast of India

The current study determined the nutritional parameters of selected species of edible marine molluscs viz., Indian squid Uroteuthis (Photololigo) duvaucelii, veined octopus Amphioctopus marginatus, spineless cuttlefish Sepiella inermis and edible oyster Crassostrea bilineata (=madrasensis) from the Arabian Sea and estuarine systems of the south-west coast of India. The selected species demonstrated balanced essential to non-essential amino acids ratio (1.04-1.52). U. (P.) duvaucelii exhibited greater quantities of sulfur comprising amino acids (0.102 g 100 g-1 wet weight) and lysine (1.566 g 100 g-1). Among polyunsaturated fatty acids (PUFAs) eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) were found to be prominent in edible portion of the molluscs studied (7.6-10.3 and 8.7-17.4% respectively). A. marginatus exhibited significantly greater n-3/n-6 PUFA (~7, p<0.05) than other molluscs. Lower thrombogenicity and atherogenicity indices (<0.45 and <0.85, respectively) make the mollusc studied during the present investigation valuable food items for cardioprotection and anti-platelet aggregation. Higher content of vitamin D3 (489 IU) and vitamin K1 (1.84 μg 100 g-1) in C. bilineata signified their importance in preventing osteoporosis. The results reveal that these species are good sources of essential elements and toxic metals were below threshold limits of recommended standards for human consumption.

Southwest Monsoon Season

Mudbank is a unique phenomenon observed along the south-west coast of India among all the Indian coastal regions during the Southwest Monsoon Season. The scientific reasons behind the formation and its persistence are vague. Mudbank is considered as a boon to the fishermen of Kerala, as they are getting reasonable catches during the occurrence of mudbanks using indigenous boats from the calm sea, which otherwise is in a fury during the rough Southwest Monsoon Season. Since the region, the Arabian Sea, is significant as a carbon sink due to its very high productivity because of different coastal ocean features, variations in the smaller and highly restricted coastal processes due to climate change can have a significant impact on the rates of global warming. Here, we consolidate the previous publications on various aspects of mudbanks with the reports of the occurrence of mudbanks on the south-west coast of India. A model for the prediction of the formation and location of mudbanks, inclusive of all the intrinsic and extrinsic parameters involved, through an extensive study is much relevant as far as the socio-economic and food security significance is concerned. Here, we discuss the most conducive factors for the formation of mudbank and its characteristics with special reference to Alappuzha, where the frequency of occurrence of mudbanks is maximum among the Indian coastal regions.
