| | | Review of the literature is an essential starting point for any endeavour in GIS, remote sensing, or mapping. Yet, reviews are often incomplete for lack of access to the material, and consequently projects experience durations that are longer and costs that are higher than need be because the accumulated knowledge has not been tapped and taken advantage of. This page sets out to mitigate that problem. It is a gateway to the literature that represents much of the accumulated global experience on using GIS, remote sensing and mapping to solve problems and issues in aquaculture and inland fisheries. Spatial issues addressed most frequently for aquaculture and inland fisheries are listed in two tables in issues section along with the number of literature records currently contained in GISFish databases. Four recent studies available for download in issues section provide background information on GISFish databases. | | | |

| | | Title | Modelling the growth of Mytilus edulis by coupling a dynamic energy budget model with satellite derived environmental data | | Author | Thomas,Y. ;Mazurié, J.;.Pouvreau, S, ;Bacher, C, ;Gohin, F.;Struski,C. ;Le Mao, P. | | Date | December 2006 | | Content Language(s) | English | | Abstract / Description | Defining criteria for shellfish farming potential appears particularly useful in order to select new sites or estimate the carrying capacity of existing ones. That requires integrating the response of bivalves to the environmental variations. The method suggested here consists on coupling a dynamic energy budget approach (last generation of generic growth model) with environmental information extracted from satellite images (chlorophyll concentration and temperature): such data have the advantage over traditional measures of being extensive, validated and non-expensive. DEB theory assumes common physiological processes across species and life stages via a set of common parameters. Recent promising applications led us to apply the DEB model to estimate the response of M. edulis to a natural trophic gradient observed in Mont Saint Michel Bay, a major shellfish farming area of North Brittany, France. In a first approach, chlorophyll may be considered as an acceptable descriptor of the trophic resource. Since the launch of the Sea_ viewing Wide Field-of-view Sensor (SeaWiFS) in 1997, followed by MODIS and MERIS, a considerable data set has been collected from satellites. Chlorophyll data have proved very useful for monitoring the phytoplankton dynamics in coastal waters. After comparing satellite data with field measures for validation, this study included (i) a calibration of the growth model in one location of the bay where growth data are available, (ii) a validation of this model at the scale of the mussel culture area, and (iii) a large scale application of the method, covering the whole bay. This study may be considered as a general method to account for environmental impacts (food depletion) and responses (growth, reproduction) of an organism in varying environments. Such biological response assessment may be used for site selection, when applied to a species of interest for aquaculture. It may also be usefully included into a Geographical Information System describing the potential uses of a coastal area. | | Publisher | Ifremer | | Publication Location | France | | Download | | | Keywords | SHELLFISH; GIS; REMOTE SENSING | |
