Book (series)Advances in geographic information systems and remote sensing for fisheries and aquaculture 2013
Also available in:
No results found.This publication is an essential guide to understanding the role of spatial analysis in the sustainable development and management of fisheries and aquaculture. The publication is an easy-to-understand publication that emphasizes the fundamental skills and processes associated with geographic information systems (GIS) and remote sensing. The required spatial data and computer hardware and software are outlined, as well as the considerations necessary to implementing a GIS. Current issues, status and applications of GIS and remote sensing to aquaculture, inland fisheries and marine fisheries are described to illustrate the capabilities of these technologies. Emerging thematic issues having a spatial context in fisheries and aquaculture in the near future are also described, and finally useful clues as how best to overcome challenges to accomplishing GIS work are addressed. -

The rapidly rising world population is causing both a pressure on land and water space and the need to greatly increase food output. A realistic and practicable way of supplying more food protein is to increase fish production through the extension of aquaculture and inland fisheries. Since production sites for these activities need to satisfy fairly complex location criteria, it is important that suitable areas are identified and preferably designated in advance. The location criteria which con trol aquaculture and inland fisheries are identified and described. These mainly consist of physical and economic considerations though social factors may be important. It is necessary to obtain data to allow for its mapping. The various alternatives for assembling this data are described. Two fields of applied science and technology have recently emerged which, when used in combination, can greatly assist in the spatial decision-making process. The fundamentals of the first of these, remote sensing, are described giving particular emphasis to the commercial, high resolution environmental satellites and the sensing devices which they carry. The manner in which the aerial photographic and digital images which are produced can be processed and applied to the search for optimum fish production locations is described, and then indications are given as to where and how remotely sensed data can best be procured. Once the various types of locational data are assembled, the necessary maps o n which location decisions are made can be drawn up. This task can be greatly expedited by using the second applied science and technology field, that of “geographical information systems”. This emerging methodology relies on the increasing power of the computer to process vast amounts of spatially referenced and encoded data in such a way as to produce any desired maps, tabular or textual output, using a large array of ways to manipulate the data. The required computer hardware and software are reviewed, including examples where appropriate, and we show the considerations which are necessary in setting up a geographical information system for the development and management of aquaculture and inland fisheries. We conclude by giving an divergent selection of relevant case studies. -
Book (series)Geographic information systems, remote sensing and mapping for the development and management of marine aquaculture 2007The objective of this document is to illustrate the ways in which Geographic Information Systems, remote sensing and mapping can play a role in the development and management of marine aquaculture. The perspective is global. The approach is to employ example applications that have been aimed at resolving many of the important issues in marine aquaculture. The underlying purpose is to stimulate the interest of individuals in the government, industry and educational sectors of marine aquacul ture to make more effective use of these tools. A brief introduction to spatial tools and their use in the marine fisheries sector precedes the example applications. The most recent applications have been selected to be indicative of the state of the art, allowing readers to make their own assessments of the benefits and limitations of use of these tools in their own disciplines. The applications are organized issue-wise along the main streams of marine aquaculture: culture of fishes in cag es, culture of shellfishes and culture of marine plants. A case study is included that illustrates how freely downloadable data can be used to estimate marine aquaculture potential. Because the ultimate purpose of GIS is to aid decision-making, a section on decision support tools is included.
