Changes from plenary report to adopted text

Added- Digital video is typically preferred for capturing information during the different phases of vessel activity, but still images can also serve as a viable option, especially where storage capacity is limited. An optimal configuration can involve a camera setting, using video for specific areas, cameras, or moments, while utilising still photos for others.

Added- EM records shall include, at a minimum, location, date, and time stamps, and to the extent possible, vessel ID, and be capable of being integrated with other data collection and monitoring tools (for example sensors).

Added- The onboard interface shall include an on-board screen, or equivalent interface, to allow verification by the master or crew as regards the correct functioning of the EM equipment.

Added- The EM provider shall ensure that radio frequency interference from EM equipment with other on-board vessel communication, navigation, safety, geolocation devices or fishing equipment is prevented.

Added- EM Equipment shall automatically and autonomously collect EM records to generate the required EM data and shall be tamper-evident/resistant and shall record automatic alerts which shall be provided to the appropriate EM Coordinator and EM provider in near-real-time in cases of malfunctions, manual activation/shutdown, manual data input, external data manipulation, or attempts to tamper with the equipment or EM records. If those recorded automatic alerts cannot be sent in near-real-time to the EM programme coordinator and EM provider, they shall be provided as soon as possible, along with other EM records at the end of the corresponding trip. It shall also be possible for data recording to be controlled manually, but only in the event that the EM equipment fails to start or stop automatically, and any manual activation shall trigger an automatic alert. Manual shutdown shall not be permitted.

Added(2) Cameras

Added- Cameras shall be sufficient in number and quality to meet the data requirements of the EMS, with high-resolution images that allow the identification of species, specific fishing activities and the vessel’s surroundings.

Added- Onboard EM hardware components shall be sufficiently dust and water resistant and durable enough to operate reliably under the range of conditions expected in their location on vessels.

Added- Cameras shall be capable of recording video and/or still images, as appropriate to the purpose of the individual camera. For cameras used for species identification, video shall have a resolution no less than 720p, with a minimum frame rate of 5-10 FPS. Still images shall have a minimum capture interval of no more than 1 second, with a resolution of no less than 2MP.

Added- Placement of cameras shall provide clear and unobstructed views of the areas that are being covered.

Added- On purse-seine vessels, the cameras shall cover, at a minimum, the working deck (both port and starboard sides), the net sack and the brailer, the foredeck or amidships, and (if applicable) the well deck and conveyor belt. Descriptions and image for an example of camera locations in class 2-6 purse-seiners is provided in Table 1 and Figure 1.

Added- On longliners, the cameras shall provide, at a minimum, a view of all hooked fauna, both those brought aboard the vessel and, when possible, those discarded or released without first being brought aboard the vessel. Descriptions and an image for an example of camera locations on longliners that would provide these views are provided in Table 2 and Figure 2.

Added- Cameras shall be able to record activities in low and very bright natural light conditions (low and high contrasts). Nocturnal fishing activities involving species captured shall be illuminated with sufficient lighting (for example longlines). In these cases, the EM service provider shall test the image quality to ensure there is not excessive glare.

Added(3) Sensors

Added- EM equipment may also include sensors for recording non-visual data (for example vessel movement, hydraulic pressure, environmental information), and also possibly mechanisms for activating/disactivating cameras so as to focus visual data collection during activities of interest.

Added- A GPS sensor or equivalent shall be capable of automatically recording the position and, unless the EM equipment uses cameras that will record continuously, the speed and course of the vessel.

Added(4) Data storage

Added- EM equipment shall include sufficient capacity to store all required EM records, including GPS (or equivalent) records, position, date, time, vessel name and sensor information where applicable at a minimum, for the duration of a fishing trip.

Added- Vessels shall have onboard enough blank data storage devices (preferably solid-state drives) in case these must be replaced at sea. A specially trained crew member may need to replace the devices during a fishing trip if the data storage capacity is exhausted, always in coordination with the EM service provider.

Added- EM equipment shall include separate duplicate backup devices, to ensure that data are not lost if one device fails.

Added(5) Compatibility

Added- EM data shall be submitted to the IATTC in a format compatible with IATTC databases and IT resources such as data structure, units, species identification/other fishing activity codes, etc.).

Added- Recorded imagery shall be recorded in a widely used and accessible video or image file format, such as MP4 or JPEG.

Added- All EM Records generated by the EM system shall be compatible with EM analysis software being used by the EM Review Centre where EM Records shall be sent to generate EM data.

Added(6) EM equipment maintenance

Added- At sea, all maintenance, repairs and replacement activities of EM equipment shall be conducted by a designated trained vessel crew member(s), only in coordination and when remotely instructed to do so by the EM service provider.

Added- On land, all maintenance, repairs and replacement activities of EM equipment shall be conducted a technician in coordination with the EM service provider.

Added- Each vessel shall have a designated crew member responsible for routine camera lenses cleansing, to ensure the clarity of EM records, according to a protocol to be developed by IATTC scientific staff. Appropriate cleaning materials must be used to avoid lense damage, and shall always be available onboard.
