Geomorphological Evolution of Estuaries: The Dynamic Basis for Morpho-Sedimentary Units in Selected Estuaries in the Northeastern United States

The coastal geomorphological processes of alongshore transport and tidal currents are interacting with the attendant influences of sea-level rise and sediment supply to generate morphosedimentary units in selected estuarine systems. Constrained by the conditions promoted by microtidal situations in barrier island settings, vectors of sediment transport have established spatial sequences of morphologies and sediment types that are components of shellfish habitats. Greater depth and decreasing grain-size toward the mainland are common characteristics in five northeastern U.S. estuarine systems. The patterns are repeated at various scales among the lagoon-type estuaries as well as within the estuarine settings to establish geospatial associations of geomorphology and habitat.

Fish quality and processing in Malawi: responding to challenges through institutional capacity building

Fish processing and quality control in Malawi are still poorly developed. Traditional fish processing methods are widely employed resulting in considerable post-harvest losses. One of the major challenges to steady and sustainable development in fish processing and quality management is the lack of adequately trained personel. This is directly reflected in poor institutional capacity. This project analyses the situation in fish processing and quality management in Malawi to identify gaps that require improvement. Specifically, the project assesses the role of training institutions in Malawi in capacity building for fish processing and quality management. The institution under discussion in this project is the Aquaculture and Fisheries Science Department at Bunda College of Agriculture, Malawi which is responsible for training students in aquaculture and fisheries science at the undergraduate level.Improvement in the teaching of fish processing and quality management in the Department of Aquaculture and Fisheries Science was identified as the major gap requiring action. The current teaching syllabus was thus analysed to identify weak areas. In conclusion, the project developed (as the major output) a teaching handbook for the Department of Aquaculture and Fisheries Science.

Quality problems in fish processing

Various problems associated with the quality of the fishery products like spoilage, discolouration, microbiological problems, etc., are outlined. The reasons and remedial measures are discussed. The importance of proper handling, processing and hygiene is stressed.
