Aquaculture contributed 43 per cent of aquatic animal food for human consumption in 2007 (e.g. fish, crustaceans and molluscs, but excluding mammals, reptiles and aquatic plants) and is expected to grow further to meet the future demand. It is very diverse and, contrary to many perceptions, dominated by shellfish and herbivorous and omnivorous pond fish(More)
Site selection is a key factor in any aquaculture operation, affecting both success and sustainability. Moreover, it can solve conflicts between different coastal activities , making a rational use of the coastal space. Geographical information systems (GIS) have become of increased significance for environmental planning and assessment mainly because of(More)
World aquaculture is undergoing a massive expansion , both in quantity and quality of products and this is set to increase over the next few decades especially if aquaculture is to satisfy the world demand for fish products in the face of dwindling fisheries (FAO, 2002). Clearly, the industry needs to be sustainable in the medium to long term and(More)
19 20 Modern Geographical Information Systems (GIS) offer a powerful modelling 21 environment capable of handling large databases. They are a very suitable 22 environment in which to develop a suite of tools designed for environmental 23 management of aquaculture sites, including carrying capacity prediction, land-water 24 interactions and multi-site(More)
A 7-week feeding trial was conducted to investigate the effects of replacing fish meal by autoclaved Salicornia bigelovii seed meal (SSM), supplemented with varying cholesterol levels, on feed intake, growth performance, body composition and survival of Nile tilapia Oreochromis niloticus fingerlings under laboratory conditions. SSM was tested at different(More)
The present study identifies and quantifies appropriate sites for brackish water aquaculture development in southwestern Bangladesh using remote sensing, GPS and geographical information systems (GIS). A colour composite Landsat TM image from 1996 covering the southwestern part of Bangladesh was used to identify the extent of brackish water and to classify(More)

A non-invasive system for monitoring fish underwater is described. A 3D point distribution model (PDM) model can be fitted on stereo images for fish examination. Currently the model fitting algorithm requires manual initialisation. Therefore experiments were carried out to investigate the usefulness of an n-tuple classifier as a tool to initiate the model(More)
Combining GIS with neuro-fuzzy modeling has the advantage that expert scientific knowledge in coastal aquaculture activities can be incorporated into a geospatial model to classify areas particularly vulnerable to pollutants. Data on the physical environment and its suitability for aquaculture in an Irish fjard, which is host to a number of different(More)
