Fishery biology and harvest technology
About the course
An introduction is given to the methods traditionally used to investigate exploited aquatic organisms. This includes laboratory methods for determination of population parameters, and field work for direct estimation of fish density. The concept of a model is introduced: we adapt it to widely diverse species and international fisheries, and make simple quantitative predictions of the suitability of different exploitation regimes. Harvest technology deals with a general description of the vessel and gear technology used in different parts of the world. We deal with fish behaviour, types of materials, operation methods, selectivity, and fish detection and density estimation with hydro-acoustics. New developments in the pursuit of energy efficient and environmentally friendly gear, as by-catch reduction, and user friendly gear, will be addressed.
