2015 AFS EM Symposium: Principles of Fishery Program Reporting Design – M. Brady

PDF: Principles of Fishery Reporting System Design_M. Brady

Abstract: Fishery reporting systems accept human input via multiple subsystems, where the subsystems are reporting on the same event, a fishing trip. Human data input presents challenges to the designer as a common source of error and excessive burdens on human reporters. Using multiple subsystems to report on the same event can result in redundancies, inconsistency, and trip matching errors. Furthermore, human data input and multiple reporting subsystems can interact in a way that propagates additional errors within the system. This presentation provides a set of design principles for managing human data input and design principles for proper integration of reporting subsystems. Reporting systems based on these principles are simpler, more efficient, and far more accurate.


2015 AFS EM Symposium: Red Herrings – Looking Outside Fisheries For Insights On Data Management – K. Wing

PDF: Red Herrings- Looking Outside Fisheries For Insights On Data Management_K. Wing

Abstract: Integrating data collected through new technologies, like electronic monitoring or reporting systems presents, fishery managers with a host of new challenges. Data validation, reconciling multiple information streams, and balancing public transparency requirements with privacy concerns are not issues unique to fisheries.

How have financial managers, law enforcement, hospitals, and the IRS handled similar challenges as they built out new systems to meet compliance requirements, improve efficiency, provide public access, and create interfaces for customers and software developers? This presentation will explore lessons in data modernization from other fields and recommend next steps for improving state, regional, and federal fisheries information systems.


2015 AFS EM Symposium: Integrating EM and Other Data Into a Modernized Fishery Dependent Data System – D. Christel

PDF: 2015 AFS EM Symposium – Integrating EM and Other Data into a Modernized Fishery Dependent Data System_D. Christel

Abstract: The needs/uses of fishery dependent data have changed over the past 20 years, yet data collection, storage, and analytical processes have remained relatively static. Emerging data needs require a reexamination of existing collections and processes to provide more detailed, integrated, and timely data for all stakeholders. In 2013, the NMFS Northeast Fisheries Science Center and Greater Atlantic Regional Fisheries Office began an effort to modernize the regional fishery dependent data system by identifying the existing and anticipated data needs/uses of all data stakeholders.

By separating the needs and uses from collection mechanisms, data streams were emphasized instead of data collection mechanisms. This approach helped identify ways to reduce redundancy, increase accuracy, and overcome procedural and technical limitations… Read More »

2015 AFS EM Symposium: One Fish, Two Fish, Red Fish, Rockfish: Human‐Based Video Review in a Hardware‐Focused World

PDF: 2015 AFS EM Symposium-One Fish, Two Fish, Red Fish, Rockfish- Human-­‐Based Video Review in a Hardware-­Focused World_C. Donovan

Abstract: Electronic monitoring has recently become an important topic in commercial fisheries. While most discussions tend to focus on the hardware and management aspects, it seems easy to overlook a crucial element of any electronic monitoring program: the point at which data are captured during the human conducted review of collected video and sensor data. Specialized software is important for expediting the review of raw video data since the integrated features and efficiency of the software affect the resulting review times, and therefore the cost of review, as well as overall data quality. Pre-analysis review of electronic monitoring data could be improved by further research and development of specialized software, and attempts to solve the already existing problems… Read More »


2015 AFS EM Symposium: The British Columbia Groundfish Electronic Monitoring Experience in Relation to Data Quality and Impact of the Data on Assessment and Management

PDF: 2015 AFS EM Symposium – British Columbia Groundfish Electronic Monitoring Experience in Relation to Data Quality and Impact of the Data on Assessment and Management_R. Stanley

Abstract: Catch in the groundfish hook and line fishery on Canada’s west coast has been monitored since 2006 by an interrelated suite of components. In addition to 100% EM coverage, these include full independent dockside monitoring, fisher logbooks and complete retention of rockfishes. Each component, in spite of its weaknesses as a stand-alone monitoring tool, makes an essential contribution without which the overall program would fail to meet the minimum objectives. Over the ensuing eight years, the program has surpassed expectations in meeting conservation and operational information goals by providing adequate and timely estimates of total catch for all quota and many non-quota species. This presentation will first focus on the impact that the improved data has had… Read More »


2015 AFS EM Symposium: Turning Fishery Information Needs into Performance Standards for an Electronic Monitoring Program

PDF: 2015 AFS EM Symposium-Turning Fishery Information Needs into Performance Standards for an Electronic Monitoring Program_M. Hooper

Abstract: Several U.S. commercial fisheries are considering implementing electronic monitoring (EM) systems as an alternative to human observers for at-sea catch and compliance monitoring. Fishery managers, scientists, fishermen, and other partners are in the throes of developing program designs, performance standards, and technical specifications that would meet their objectives, as well as legal requirements of the Magnuson-Stevens Act and other statutes. They are looking to the NMFS for guidance on what specific requirements and minimum standards must be met. In some cases, NMFS is breaking new ground in application of some Federal statutes to EM systems, which have only been implemented on a limited scale in U.S. fisheries. This talk will address the following questions, drawing on examples… Read More »


2015 AFS EM Symposium: Evaluating the Effectiveness of Dockside Monitoring Using an Electronic Monitoring System in the Maryland Blue Crab Fishery

PDF: 2015 AFS EM Symposium-Evaluating the Effectiveness of Dockside Monitoring Using an Electronic Monitoring System in the Maryland Blue Crab Fishery_H.W.Slacum

Abstract

Self-reporting is a common method to document harvest, but the accuracy of reported harvest is uncertain without independent methods of harvest verification. General documentation errors, forgetfulness and intentional misreporting are common problems and can profoundly impact the accuracy of reported harvest. As mobile accessible electronic reporting systems become more prevalent they have the potential to improve the timeliness and accuracy of self-reported harvest. However sources of misreporting and incentives to misreport will continue unless techniques are in place to evaluate reporting accuracy and report compliance. Independent verification techniques such as at-sea observers, dockside monitoring and dealer reporting can be implemented to establish crosschecking and auditing of selfreported data and to increase incentives for industry to provide accurate… Read More »


Innovative Camera Systems Applications for Electronic Monitoring

Innovative Camera Applications for Electronic Monitoring_Wallace, et al., 2015

Abstract

Electronic monitoring has been shown to be an effective tool to meet a variety of fisheries monitoring objectives in compliance-based pro­grams. However, these systems have not been effective in delivering individual fish data similar to information collected by an observer.

Development of new camera-based systems, methods, and tools is critical for collecting scientific data to inform management. A camera system being developed at the Alaska Fisheries Science Center greatly improves the functionality and addresses many of the limitations of electronic monitoring systems. This system provides the ability to automatically collect length measurements in addition to monitoring for compliance. System capacity to identify and automatically capture high quality (HD) stereo images of catch events, for efficient identification of… Read More »
