This research project is aimed at evaluating the impact of climate change on the growing mud crab (Scylla serrata) fisheries industry in Tanzania. The specific objectives are: to assess the contribution of mud crab fattening to the livelihoods of peoples; to assess local perceptions on climate change and associated impacts on mud crab fattening and fishery; to determine the abundance and distribution of mud crab stocks in the wild under current climate change; to determine the climate change factors such as salinity, water temperature, dissolved oxygen and meteorological data such as precipitation, water discharge and air temperature and to conduct training of two graduate students. The study will be conducted in Pangani and Rufiji districts along the Tanzanian coast. The abundance of mud crab wild stock will be estimated using Catch per Unit Effort (CPUE). Environmental variables and meteorological data will be collected in both sites. Socio-economic survey will be conducted using well structured questionnaires. The findings will help: to give an insight on economic benefit of mud crab farming to the coastal communities, to know the effect of climate change on the abundance and distribution of mud crab wild stock, and to suggest whether mud crab farming is best option adaptation strategy for impact of climate change to coastal communities.
