ABSTRACT

 

West Bengal coastline spreads over the districts of East Midnapore and South 24 Parganas. Mandarmani, at about 172 kilometres from Kolkata, India is a new attraction in the tourist map. Huge number of hotels and resorts are developed. But waste management is a big problem in the newly developed beach having no facilities of municipalities. A survey was conducted on the basis of questionnaire and personal interview among the hotel staff and it was found that about 10% of wastes is incinerated and nearly 25 % is used in land fill. Kitchen wastes are regularly collected and supplied to fish farmers in nearby villages for culture of African catfish Clarias gariepinus. Visit to the culture area revealed that in isolated and stagnant ponds fingerlings are cultured. Kitchen refuse collected from the beach hotels are the main source of supplementary food. Clarias gariepinus is a freshwater fish. They grow quickly, attain a large size and can withstand wide range of environmental conditions. Due to the predatory and voracious feeding habit of this fish it is not recommended to be cultured in natural water bodies with other fishes. However, it can be safely cultured in monoculture system as in the studied case. It is an example of perfect integration where waste is being utilized as resource.
