PowerPoint: Technology Investments for Tomorrow’s EM Programs

Expanding information needs in commercial fisheries has led to the introduction of EM as a rapidly growing alternative to observer programs. EM is still in its infancy and while EM and observers seek to achieve similar information outputs they are fundamentally different programs in terms of design, operational needs and cost. A successfully implemented operational EM program is the result of optimizing data needs (quantity, quality, and timeliness) with the fishery characteristics, the technology, the operational requirements to support the deployment of EM and available funds.

A multitude of studies has shown that many of the standard fishery information needs can be successfully achieved using EM. Future technology investments hold promise for improving information quality, gathering new types… Read More »

PowerPoint: It’s All Connected- Saltwater Inc. Electronic Monitoring

Technology has changed the way Saltwater does business – literally — from collecting fisheries data with onboard and shoreside observers to working with both observers and electronic monitoring systems.

With EM, we operate at the intersection between fishery managers and fishermen, between policy and implementation, and between all the data one might want and what can be collected, reviewed, and stored at a reasonable cost. We design and build EM systems and software, install them on boats, train skippers, provide ongoing technical support, and review and analyze data. We consider it our job to continually look for ways to make the collection and use of EM data better, faster, and cheaper. More and better data increases the odds… Read More »

PowerPoint: What You Get for What You Pay

Accurate catch monitoring is critical to successful management of output controlled fisheries. Since adopting such a system with the implementation of catch shares in 2010, monitoring in the New England groundfish fishery has been conducted with at sea monitors. These human observers use multiple methods to estimate kept catch and discards leading to varying levels of data quality. As New England transitions from agency to industry funded monitoring programs, additional scrutiny has been placed on the costs of collecting these data. In an effort to explore potential cost savings, pilot programs have used cameras, GPS and sensors to electronically monitor catch. We analyze the cost efficiency of numerous monitoring strategies accounting for differences in quality of the data collected…. Read More »

PowerPoint: Seatube – Satlink’s on Board Electronic Monitoring and Video Recording Solution

Satlink is a Spanish engineering company that develops technological solutions in collaboration with the fishing industry, NGOs and governments worldwide. These solutions support seafood traceability and manage, optimize and preserve fish resources.

The Satlink SeaTube System is a cost effective on-board Electronic Monitoring (EM) and video recording solution for commercial fisheries. In addition to being a compliance monitoring system, SeaTube also allows the vessel’s owner to view vessel activity from a PC in the office.

Satlink has teamed up with Digital Observer Services (DOS), an independent consultancy company and provider of EM services. DOS provides video review services as well as training and software support to organizations wanting to perform their own video reviews and analyses.

The SeaTube EM system with support from DOS… Read More »

PowerPoint: Machine Learning for Big Fishery Visual Data

PowerPoint: Utilizing Wireless Technologies to Monitor New England Groundfish

Once a profitable fishery supporting coastal communities, the groundfish fishery in New England is in crisis. One factor is the mixed stock nature of the fishery where stocks with low catch limits constrain the harvest of more abundant stocks. In addition, climate-mediated changes in this region are unprecedented, and the impacts on marine fisheries resources, such as changes in distribution and productivity, are increasing. There is a need for more comprehensive and accurate data collection to understand the current and future state of the Gulf of Maine fishery resources. Adaptive electronic tools can help address these data gaps. The Gulf of Maine Research Institute (GMRI) has begun developing an extension of traditional electronic monitoring (EM), called the Fisheries… Read More »

PowerPoint: Integrated Operational Approach to EM & ER Onboard Fishing Vessels-Now and Tomorrow

Fisheries management is plagued by lack of verifiable data for compliance and stock assessments. Low vessel observer coverage, and delays in data transfer, transcription, integration, and analysis are the norm. These problems hinder timely analysis and updates of fishing regulations relevant to existing stocks. Fishing capacity is increasing around the world; incidental catches of protected species, bycatch discard, and IUU are critical issues. Technological advances and cost reduction bring much opportunity applicable to the fishing industry. The authors developed an integrated EMR solution and several technologies will be discussed.

Paper logbooks are limited to alphanumerical content and suffer from accuracy concerns. Electronic reporting (ER) replaces paper logbooks and allows for enhanced data entry and timely delivery. Electronic monitoring (EM) entails… Read More »

PowerPoint: Open Source Software Platform for Electronic Monitoring

Sea State Inc. has developed a suite of software applications to support commercial fisheries electronic monitoring (EM) data acquisition, review, summarization and archival. This National Fish and Wildlife Foundation funded project, in partnership with Saltwater Inc. and Chordata LLC, provides a platform that is adaptable to marine fisheries nationwide. The source code is available under the Gnu Public License, ensuring that all future enhancements will be open source as well.

The shipboard component of the software works on a wide range of hardware: from simple data-loggers without cameras up to systems with eight or more cameras. It is designed for flexibility – system behavior is controlled by configuration rules based on data from GPS, hydraulic pressure, reel rotation and video… Read More »

PowerPoint: Query Learning for Fish Identification

In fishery community, image-classification-based supervised approaches have been well studied for species identification. However, the classifiers learned from one dataset usually cannot directly be applied for a new dataset since the data captured from different years or regions often have large difference, like different colors, camera distortions and distributions of species. It is unreasonable and huge expensive to label the new data to train new classifiers. Hence, we propose a novel method with the combination of query learning and semi-supervised learning to address this challenge with only a small amount of data need to be labeled. First, an uncertainty measure is designed based on the distance between labeled and unlabeled samples in the transformed feature representations through support… Read More »

PowerPoint: Intelligent Monitoring Systems for Fishery Applications

The Observer program at Alaska Fisheries Science Center have been conducting research and development of new innovative electronic monitoring (EM) technologies to help address challenges for collecting scientific data to support catch estimation. Work focuses on development of new camera-based systems, methods, and tools while leveraging the latest development in computer vision to improve system functionality and offering potential solutions.

Chute and rail based camera systems are under developed to support and improve EM data collection from both trawl and longline fisheries. The camera chute system is technologically advanced and currently assesses image quality, catch count, length measurement and species identification. This functionality is also being actively developed for the rail camera systems. Further development of automated event –… Read More »
