Report on 2014 Solomon Islands Longline E-Monitoring Project

 

This report by Hosken, et al., summarises the results of a Video Electronic Monitoring project conducted on tuna longline fishing vessels operating in Solomon Islands waters during 2014.

The main objective of the project was to investigate the extent which Video Electronic Monitoring system (E-Monitoring) can record the data normally collected by observers on-board tuna longline vessels based on the required minimum data fields specified under the Western and Central Pacific Fisheries Commission (WCPFC) Regional Observer Programme (ROP).

The project partners were Tri Marine, National Fisheries Developments (NFD), Yi Man Fishing Company, Satlink (the service provider), Pacific Islands Forum Fisheries Agency (FFA), Oceanic Fisheries Programme of the Secretariat of… Read More »

EM Info Admin EM Info Admin

Published June 29, 2016

The Program at a Glance

 

  • Fishery: Alaska Small Boat / Longline
  • Geographic Scope: Southeast, Southcentral and Southwestern waters of Alaska.
  • EM Program Purpose: Discard estimation from EM video footage, validation of seabird deterrent gear deployment.
  • Pilot Project Implementation: 2014-2017
  • Anticipated Program Implementation: 2018
  • Number of Participating Vessels: Up to 60 in 2016 Pilot; up to 90 in 2017
  • Questions and Challenges:
  • Operations: How to estimate at-sea discards directly from EM video rather than through a logbook audit approach.
  • Operations: How to strategically deploy EM units on a fleet that operates over a wide area and for irregular periods of time to obtain good data
  • Operations: Developing cost effective deployment and data retrieval procedures
  • Confidentiality/record-keeping/archiving: Fishermen have questions about confidentiality,… Read More »

    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 »
