Spatial and temporal changes in pot-fishing effort and habitat use

Spatial and Temporal Participation in Recreational Fishing

Characterizing Fishing Effort and Spatial Extent of Coastal Fisheries

Biodiverse coastal zones are often areas of intense fishing pressure due to the high relative density of fishing capacity in these nearshore regions. Although overcapacity is one of the central challenges to fisheries sustainability in coastal zones, accurate estimates of fishing pressure in coastal zones are limited, hampering the assessment of the direct and collateral impacts (e.g., habitat ...

monitoring temporal and spatial changes in land use in the shazand watershed

the present study aimed to monitor the land use change in the shazand watershed with different development policies using land use net changes and exchanges in land change modeller (lcm) forperiod of1973to2014and in sub-watersheds scale. in the study period, rangeland area reduced about 380 km2 and rainfed and irrigation farm lands increased successively 100 and 150 km2 in the first and the sec...

Spatial and Temporal Variations of Groundwater Quality for Agricultural Use in Gavkhooni Basin

In this study, the quality of groundwater aquifer of Gavkhooni basin was investigated in agriculture. For this purpose, water quality data related to 96 wells prepared by Isfahan Regional Water Authority during the statistical period 2015-2016 were used. In this study, sodium parameters, electrical conductivity, chloride, hydrogen bicarbonate and sodium absorption ratio (SAR) were used. Then, g...

The Use of Gis to Analyse the Spatial Distribution of Fishing Effort in Coastal Fishery

Based on two models focussing on the analysis of the spatial components of the fishing effort distribution, we present a global approach which has been formalised in order to develop a computerized simulation tool called FAST (Fishing Activity Simulation Tool), distributed as an extension of ESRI ArcView GIS Software. FAST defines a logical framework under which the knowledge about fishing effo...
