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 »

New England Electronic Monitoring Project Phase III

The goal of the New England Electronic Monitoring (EM) Project was to investigate the potential for using EM within the broader Northeast Multispecies Fishery (NE groundfish fishery) catch monitoring program. EM systems are designed for the automated collection of fisheries data while vessels are at sea. They collect high-frequency sensor data and closed-circuit television (CCTV) imagery during fishing or related activities which are then reviewed post-trip to provide data needed for fisheries management, compliance, and/or science.

Phases I and II of the project were completed and documented in 2010-2013 (Pria et. al., 2011, 2012) and laid the initial groundwork for understanding how EM could best be applied in the monitoring needs of the NE groundfish fishery. These results… Read More »

Preliminary Study About the Suitability of an Electronic Monitoring System to Record Scientific and Other Information from the Tropical Tuna Purse Seine Fishery

This paper was published in 2015, authored by J.P. Monteagudo.

Summary

Electronic monitoring systems (EMS) are used in some fisheries to collect the same types of scientific information that human observers can collect, and in some cases for compliance with existing regulations. An EMS system was tested previously onboard a tropical tuna purse seiner in the Atlantic Ocean and it showed that the system could perform very well in many tasks. Since then, 17 purse seine vessels operating in the 4 RFMO’s, have been equipped with a different EMS that has been developed recently by SATLINK (SeaTube). In this paper, we present preliminary analyses comparing information collected by human observers from the IEO and… Read More »

This paper is available from ScienceDirect here . It was published in February, 2014.

Abstract

Mitigating the environmental impact of commercial fishing, by avoiding, minimizing and compensating for adverse effects, is core business for fisheries management authorities globally. The complex interplay of ecological, economic, and social considerations has often resulted in bycatch management being reactive, confrontational and costly. In many cases it has been difficult to demonstrate success and to establish whether bycatch management has been efficient or effective. This article proposes standards for bycatch management following reviews of literature, international agreements and Australian domestic fishery management policies, and consideration by many technical experts and several stakeholder representatives. The standards have been developed using Australian Commonwealth fisheries – and the international… Read More »

Following on the success of the electronic forms (eForms) for Port Sampling which use an Android tablet application (App) for improved quality and timeliness of data collection, the Papua New Guinea National Fisheries Authority has developed eForms for purse seine vessels’ e-reporting of Regional Purse Seine Logbook and Observer Work Book data.

Convolutional Neural Networks for Counting Fish in Fisheries Surveillance Video_French, et al.

Abstract: We present a computer vision tool that analyses video from a CCTV system installed on fishing trawlers to monitor discarded fish catch. The system aims to support expert observers who review the footage and verify numbers, species and sizes of discarded fish. The operational environment presents a significant challenge for these tasks. Fish are processed below deck under fluorescent lights, they are randomly oriented and there are multiple occlusions. The scene is unstructured and complicated by the presence of fishermen processing the catch. We describe an approach to segmenting the scene and counting fish that exploits the N4-Fields algorithm. We performed extensive tests of the algorithm on a data set comprising 443 frames from 6 belts. Results… Read More »
