1992-007 Geographical Fisheries System.pdf

Summary

Geographical Fisheries System (GFS) was developed as part of a project jointly funded by the Fisheries Research and Development Corporation, Queensland Fisheries Management Authority and the Department of Primary Industries, Queensland and based at the Northern Fisheries Centre, Cairns. The project 'Small prawn habitat and recruitment study' (FRDC 92/7) ran from July 1992 to June 1995. GFS was developed during the period August 1994 to June 1995 as an animated, interactive model for displaying the data collected during this project. It can also display other user's data, making GFS a more flexible tool.
 
Geographical Fisheries System (GFS) is an interactive, animated tool for visualising fisheries data. It is able to read M.ap Info mif files for importing maps, whilst Access, Paradox, SQL Server, Btreive, Excel and text files can be read for data input. The data can then be displayed on a map. GFS has the facility to track movement through time on the map (such as in tagging data). GFS also has thematic mapping functions (such as densities or species composition at each site mapped through time). Although GFS is set up to be specific to this project, it has been developed to be flexible enough for many different applications depending on the data input.

1992-007 Exploring Strip Closure Options in the Turtle Group Region Using GFS.pdf

Summary

GFS is provided with data from the Turtle Group region that you can use to explore strip closure options. As GFS is a flexible tool, there are a number of ways you can approach this task. What follows is a suggested path for exploring closure options. As you become more familiar with GFS,you may develop your own procedure, or even use your own data for other regions. Consult the GFS User's Manual or the on-line help for full details of how to use the features described below.

Summary

This project was undertaken in collaboration with Pacific Export Services Queensland Pty Ltd and had the primary objective of developing a powdered shark cartilage product on a pilot commercial scale for the domestic and export markets. The investigations undertaken in this project required several discrete development steps: sourcing of the raw material, removal of excess flesh from the backbone, development of the drying, milling and packaging protocols, establishment of suitable quality manufacturing and testing procedures, and identification of the markets and market requirements. Considerable time and effort was committed to the development of the appropriate techniques and equipment necessary for the production of a quality powdered shark cartilage product. The procedure which is currently employed for shark cartilage powder manufacture involves a heat-pump drying process and a sequence of milling steps. The final product must maintain a low moisture content and produce a fine (<40µm) powder. Additionally, considerable expertise was developed in the handling of the powdered product, and in the further value-adding of the powder into encapsulated and tableted products. Although this project has concluded, the author has a keen interest in the product and in the potential for alternative uses of the shark cartilage. These uses include: treatments of various inflammatory ailments (e.g. arthritis), extraction of collagen or gelatin for the food or pharmaceutical industries, and extraction of chondroitin sulfate for use in corneal transportation media. This project has developed ideas also in the area of total utilisation of the shark, which includes such areas as leather, meat, offal and fin. The project has successfully developed a method for the manufacture of a fine white powder derived from the backbone of the shark. The commercial partner is very satisfied with the results and is keen to continue the development of the process and improvement of the product. Sales of the product in the domestic and international arenas have surpassed expectations.
