Ornamental fish are fish that are kept in home aquariums or for recreational reasons. it's considered together of the fastest-growing in Malaysia's agriculture sector, especially within the export-oriented sub-sector. In 2015, a ban on the importation of certain Malaysian ornamental fish to the European Union (EU) was imposed. Purpose: The study was designed to identify the location of fish farmers, using GIS and remote sensing supported by off-farm employment data from a sample population of 30 ornamental fish farmers in Sungai Siput, Perak. Design/methodology/approach: The respondent's socio-economic profile is described using descriptive analysis. Cross-tabulated the link between farming involvement and the selected independent variables. The null hypothesis, however was tested using chi-square analysis. Farming operations were linked to spatial attributes in separate regions using a GIS and a Spot-6 images. Findings: This study found that off-farm employment is a viable alternative method for improving the income and well-being of Malaysian ornamental fish producers. As a result, identifying on-farm and off-farm job locations, as well as other geographical characteristics, is simplified. Diversification of employment, on the other hand, aids in income smoothing by distributing risk across multiple occupations. A database of farm locations was built and spatial analysis was performed in order to monitor the farm by being spatially monitored from a web-based GIS system. The European Union (EU) imposed a goldfish and koi carp fish embargo in 2015, which had an impact on the entire business. In order to overcome the matter, the FBD developed the BioDOF-Map system which comprises the spatial and non-spatial data on the ornamental fish farmers. It is well-proven, with the help of BioDOF-Map system, there is so much more information that can be obtained and manipulated by the Malaysian government to help improve the current policy and use it as an important input in strategic plans especially in the terms of aquaculture and agriculture. Research limitations/implications: The study uses census method sampling. In the area, there were 30 farmers registered with FBD. There are numerous advantages to this, including easy access and inexpensive data collection expenses. Nonetheless, using purely aquaculture farmers sampling is also extremely limiting if the population of the study is comprised of people with various profiles. Practical implications: After certain conditions are fulfilled, An instance is, when the study was conducted, the reliability of the data has been collected would have practical implications. It is suggested that the next study should cover non-aquaculture farmers in the area. Originality/value: A web-based GIS system namely BioDOF-Map simplifies farms monitoring, which benefits the Department of Fisheries in the management of aquatic animal health has been developed in the year 2019.

Methods of data collection and analysis can be of help to support decision making. The case of the Biesbosch National Park is used to find innovative ways to figure flows of yachts, being the most important component of water traffic, and to create a model that allows the estimation of changes in yachting patterns resulting from policy measures. Recent policies oriented at building additional waterways, nature development areas and recreational concentrations in the park to manage the demands of recreation and nature conservation offer a good opportunity to apply this model. With a geographical information system (GIS), data obtained from aerial photographs and satellite images can be analyzed. The method of space syntax is used to determine and visualize characteristics of the network of leisure routes in the park and to evaluate impacts resulting from expected changes in the network that accompany the restructuring of waterways.

In the last few years, there is an increasing interest to generate visual representations of very large scientific domains. A methodology based on the combined use of ISI-JCR category cocitation and social networks analysis through the use of the Pathfinder algorithm has demonstrated its ability to achieve high quality, schematic visualizations for these kinds of domains. Now, the next step would be to generate these scientograms in an on-line fashion. To do so, there is a need to significantly decrease the run time of the latter pruning technique when working with category cocitation matrices of a large dimension like the ones handled in these large domains (Pathfinder has a time complexity order of O([n.sup.4]), with n being the number of categories in the cocitation matrix, i.e., the number of nodes in the network). Although a previous improvement called Binary Pathfinder has already been proposed to speed up the original algorithm, its significant time complexity reduction is not enough for that aim. In this paper, we make use of a different shortest path computation from classical approaches in computer science graph theory to propose a new variant of the Pathfinder algorithm which allows us to reduce its time complexity in one order of magnitude, O([n.sup.3]), and thus to significantly decrease the run time of the implementation when applied to large scientific domains considering the parameter q = n - 1. Besides, the new algorithm has a much simpler structure than the Binary Pathfinder as well as it saves a significant amount of memory with respect to the original Pathfinder by reducing the space complexity to the need of just storing two matrices. An experimental comparison will be developed using large networks from real-world domains to show the good performance of the new proposal.

Geographic Information Systems (GIS) are increasingly being used in the retail industry. This renewed interest in the system was caused primarily by the continuing improvement in the performance and cost of personal computers. Retailers use these computerized sytems, which can combine display and print information found in digital maps and tabular data, mainly for site selection and marketing applications. The cost of acquiring GIS software is relatively less,ranging between $500 to $6,000, compared to the costs involved in acquiring the data they require, such as geographical and demographic information.
