Electronic Monitoring: A promising alternative to At-Sea Monitoring in the New England Groundfish fishery

Poster by: Long, et al. GMRI, Ecotrust, The Nature Conservancy Download poster file

Recent U.S. federal budget cuts and looming industry cost sharing mechanisms have developed a need to explore more cost effective and sustainable alternatives to at-sea monitoring in New England’s groundfish fishery.  Electronic monitoring has proven to be a successful alternative in areas such as British Columbia’s groundfish fishery, and has gained attention across New England through recent developments from the National Marine Fisheries Service and the New England Fishery Management Council.  Despite these efforts, further research is needed to operationalize catch-handling protocols for effective data analysis, along with affordable methods to successfully implement electronic monitoring in New England’s groundfish fishery.

Hawaii longline electronic monitoring pilot study

Poster by: Eric Kingma Download poster file

The pilot study explored the use of electronic monitoring (EM) in the shallow and deep set components of the Hawaiian pelagic longline fishery. EM systems, consisting of closed circuit television cameras, sensors (e.g., GPS, hydraulic pressure and winch rotation) and a system control box, were deployed on three vessels, simultaneously monitored with observers, for a collective total of about 320 sea days, 13 fishing trips and 182 fishing events. Overall, the equipment performed well, recording data for 99.2% of the time vessels were at sea. A key strength of EM is the continuous sensor data record providing very accurate temporal and spatial information on gear setting and retrieval activities. EM image reviewers were also… Read More »

Mobile App for Recreational Angler Intercept Survey

Poster by: Edward Hibsch and Craig Miller, Pacific States Marine Fisheries Commission Download poster file

Background: NMFS review of each Pacific state’s recreational survey and sampling methodology identified a desire for electronic data capture, as it would enhance data accuracy, timeliness and efficiency.

Solution: PSMFC conducted a pilot study to test the feasibility of using a mobile application to collect angler survey data in the field. A multi-platform approach was programmed by technology vendor, Vitasys  that utilizes PhoneGap.  Initial testing indicated a preference for using an iOS application to be deployed on iPads protected by a Lifeproof case. The survey application functions without an internet connection and data is electronically transferred to a PSMFC server when a wireless connection is established… Read More »

Preliminary development of a software platform to improve the efficiency of EM video review

Karl Haflinger1, Eric Torgenson2 1Sea State Inc., 2Finsight LLC

Electronic monitoring of full-retention trawl fisheries using video surveillance has been successfully demonstrated in past years.  However, obstacles remain that could prevent widespread adoption.  We are developing, and will demonstrate key aspects of, a computer system designed to address some of these issues.

Because many current EM systems require human review of large volumes of video data from multiple cameras (often three or more), labor costs associated with reviewing data for existing EM systems prevent them from being sufficiently cost competitive with shipboard observers.  We addressed this problem by developing video content analysis techniques that can be used to pre-process EM video before review and identify periods for which review is… Read More »

Gulf of Mexico Horizontal and Vertical Longline EM Project in the Snapper Grouper Reef Fish Fishery

Elizabeth Fetherston1, Adam Batty2, Martina Beck2, Todd Philips1, Carole Neidig3, Thomas King3 1The Ocean Conservancy, 2Archipelago Marine Research, 3Mote Marine Laboratory

The Gulf of Mexico (GOM) commercial Reef Fishery includes 42 species targeted using horizontal and vertical longline gear. Ocean Conservancy and the GOM Reef Fish Shareholders’ Alliance tested the use of electronic monitoring (EM) to evaluate the suitability of EM to capture at-sea fishery data. The fishery is currently catch data poor and the goal was to design a technology based monitoring program to validate self reported data. EM systems were used for six months starting February, 2012, on two horizontal and five vertical longline gear vessels. Captains were asked to complete logbooks for each trip and event. An… Read More »

Testing Electronic Monitoring as a Compliance Tool in the U.S. West Coast Groundfish Catch Share Fishery

Dave Colpo Pacific States Marine Fisheries Commission

The U.S. West Coast groundfish trawl fishery, consisting of approximately 100 vessels, transitioned to an Individual Fishing Quota (IFQ) fishery starting in 2011. As a regulatory requirement, 100% at-sea human compliance monitoring was implemented to accurately monitor discards of IFQ species for vessel quota debiting. Human monitors can reduce flexibility in the fishery, increase costs, decrease safety and sometimes eliminate the opportunity to fish when monitors are not available on short notice. Electronic monitoring (EM) systems, if demonstrated to be a viable substitute for human monitoring, could resolve some of the limitations imposed by the need to monitor 100% of fishing activity. In 2012, trials of EM in the IFQ fishery began on… Read More »

A Novel Approach to Catch Estimation Using a Photogrammetric System

Glenn Chamberlain, Brian Rothschild University of Massachusetts Dartmouth, Dartmouth, MA, U.S.A.

At some point the cost to fund at-sea monitor (ASM) coverage of the multispecies fishery in the Northeast region of the Unites States is expected to transfer from the federal government to the fishing industry. As a direct result of this impending change, the industry has expressed a desire to examine electronic monitoring (EM) as a possible alternative to traditional monitoring approaches. Several existing EM systems have been applied to a suite of fisheries in the U.S and other countries as part of either pilot studies or operational programs. Management of the multispecies fishery will likely require any supporting monitoring system to produce catch weights; essentially a system which… Read More »

Innovations in Electronic Monitoring

Kathryn Carovano, Tim Carroll Saltwater Inc.

Saltwater Inc. has developed a new electronic monitoring system that is low power, easy to install, and delivers very high quality imagery. The system uses high-resolution, digital IP (internet protocol) video cameras that record up to 30 times more detail than traditional analog technology and are designed to withstand extreme environments. The system has an integrated GPS receiver, wifi connectivity, and unique compression technology that reduces data storage requirements.

The system was developed with fishermen and has been deployed on boats fishing from the West Coast, the Gulf of Alaska and the Gulf of Mexico.  In a competitive process NMFS has chosen this system for multi- year projects in Alaska and Florida.

Pacific Coast Individual Fishing Quota (IFQ) Computational Vision-Based Monitoring (CVM)

Colby Brady NOAA Fisheries, West Coast Region, Seattle

The National Marine Fisheries Service (NMFS), West Coast Region (WCR) is exploring Computational Vision-Based Monitoring (CVM) in the IFQ groundfish trawl fishery.  The goal of the research is see if CVM can reduce monitoring costs while providing better and more timely data as compared to current (1) electronic monitoring/reporting (EM, ER) hardware; (2) speciation methodologies, and; (3) logistical issues with periodic collecting and replacing of hard drives in the field.  This project is done in collaboration with General Vision Inc. (a cognitive computing hardware and software developer) and Bornstein Seafoods.  Funding for this research project was via a Fisheries Information System (FIS) grant.

This project aims to determine if CVM can be… Read More »
