Alternative resilient livelihood option for fisher-folks tsunami victims

This method was cost effective (Table 6) because this process in entirely on natural food which
eliminates the expenditure involved in artificial food supply. As the cage was made up of
galvanized wire mesh, the cleaning of debris and seaweed clinked on it be easily removed by
manual brushing or spraying high pressure water, which in turn greatly reduces the maintenance
cost.
