About this book

Presents an overview of current and future trends in the application of computer technology to fisheries research and resource management. It discusses the history of computer use in fisheries science, relating the current state of knowledge to past developments.


Contents

Part 1 Introduction: Faster computing platforms; Powerful software; Better connectivity. Part 2 Guide to some computerized artificial intelligence methods: What is artificial intelligence?; Knowledge-based systems (expert systems); Neural networks; Genetic algorithms; Simulated annealing; Some future directions for artificial intelligence. Part 3 Potential for geographical information systems (GIS) in fisheries management: Value of spatial analyses; Data sources for a fisheries GIS; Present uses of marine GIS; Some potential uses of GIS in marine fisheries science; Ways of introducing a fisheries GIS. Part 4 Quantitative fisheries research surveys, with special reference to computers: Egg and larval surveys; Mark-recapture experiments; Trawl surveys; Acoustic surveys; Integrated surveys; Auxiliary instruments; Potential survey applications of new or unique acoustic instruments or techniques. Part 5 Geostatistics and their applications to fisheries survey data: Structural analyses - the variogram; Use of the variogram - estimation of variance; Use of the variogram - kriging; More advanced structural models than the variogram; Practical example. Part 6 Pattern recognition: Image preprocessing; Identifying phytoplankton; Identifying fish stocks from otolith shape differences; Age determination and growth-rate measurements of fish; Identifying species from echo sounders; Needed developments; Problems and promises. Part 7 Computers in fisheries population dynamics: The beginnings; Fitting models to data using electronic computers; Analysis of management policies. Part 8 Multispecies modelling of fish populations: Multispecies modelling in fisheries; Individual-based approach; Multispecies example; Summary and future directions. Part 9 Computers and the future of fisheries: Opening new windows for measuring fishery dynamics; Designing robust policies for living with uncertainty; Keeping the bad guys at bay - seeing how fisheries really operate; Exploring options and opportunities - integrating assessment and management; Pitfalls - mega-models, mega-information, and mega-mistakes.
