摘要

Fisheries today are challenged with the overfishing ofdesired species, catching of weak stocks, andunderstanding the migration patterns of fish in changingoceanographic conditions. Geospatial techniques and theuse of Global Navigation Satellite Systems (GNSS) suchas GPS have opened up a new possibilities for datacollection and visualization, providing tools to assistfishers, fishery managers, and scientists in bettermanaging the fisheries. Furthermore, fishers are findingthat access to geospatial information can lead tosignificant improvements in cost-effective fishing.Although today’s technologies provides easy access at seato PNT services for navigation, it is not so well developedin providing easy-to-use positioning capabilities in thecollection and reporting of individual fish catches. Overthe past several years, systems have been developed to dojust that, but they have been bulky, difficult to operate,and pricey. For example, at-sea data collection bycommercial salmon trollers using manual methods hasalready been demonstrated by Project CROOS(Collaborative Research on Oregon Ocean Salmon) toprovide a fine-scale (space and time) picture of salmonharvest, including map visualization of catch locations,fishing effort, and sea surface and chlorophylloceanographic data. With the advent of smart phones andtablets, rich in features such as wireless communications,GPS, and significant processing power comes anopportunity to accelerate the process of data collection,providing accurate, low cost and easy to use products.When combined with technologies such as genetic stockidentification (GSI) and satellite remote sensing there areopportunities for near-real-time management, weak-stockavoidance, improved understanding of migration patternsand ocean ecology, and product tracking and marketing.This paper provides a summary of the research performedin the areas of integrating GPS-enabled Androidtechnology with wireless communication on board avessel to provide seamless reporting of fish catchinformation. It explores the operational effects of amobile platform on board a fishing vessel in acquiringand tracking GPS signals and communication of data atvarious places in and the vessel, including on deck and inthe wheelhouse, and algorithms employed to compensatefor multipath effects and signal blockage. It presents anddiscusses the issues encountered and how these wereresolved. The paper also explores the usability issuesassociated with fielding electronic equipment onboard thedecks of fishing vessels operating at sea. Finally, thepaper makes recommendations for future actions for theimplementation of positioning and communicationtechnology, operational deployment, and application todata collection at sea.
