Fish production is related fish catch and fish culture. Fish marketing is directly related to Fish traders and fishconsumers at zonal and local level.
In extreme synthesis and very schematically: the fisheries management is very complex matter. First you need to make an accurate assessment of fish resources. The assessment can be done by direct or indirect surveys. In the case of direct surveys it is to perform a series of trawl surveys statistically planned in space and time. Indirect surveys are based on catches and on fishing effort relating thereto which, by definition, must be proportional to fishing mortality. Although it is very difficult detect catches and fishing effort, it is possible to do it so statistically planned in space and time as in the case of indirect surveys. At these information can be added a lots of other information such as environmental parameters, the operation of the market etc.. Obviously all of the data and additional information must be detected under sampling plans statistically planned. If you have all this data for a sufficiently long time (at least half a dozen years) then it is possible to develop a management plan also based on geospatial technologies. Indeed, geospatial technologies are a powerful and effective tool for fisheries management.
Hi Ram,
Well, geospatial technology can help you in the understanding of the local environment characteristics. There are several environmental indicators on water and on land that need to be monitored and certainly is useful for marketing. As example, environmental conditions of land instead industrial activities nearby the fishing area. The basin characteristics and relief for water supply.
