Electronic Monitoring System Specifications

Background Electronic Monitoring (EM) technologies hold promise as data collection resources and could be used as a monitoring tool by integrating the system with other data collection programs. The Northeast Fisheries Science Center (NEFSC) conducted a collaborative four-year study (in 3 phases) from 2010-2014 with Archipelago Marine Research, Ltd. and 13 participating fishing vessels. The goal of the study was to investigate the utility of EM to observe fishing behavior and monitor catch allocations in the Northeast Multispecies Fishery.

Information presented in this paper was based on NEFSC’s data collection with EM systems, and incorporates information obtained through numerous EM service providers. The purpose of this paper is to inform implementation planning activities in the consideration of developing EM standards in an operational program.

Electronic Monitoring System 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. EM systems typically consist of a control center, a user interface (monitor and keyboard), a suite of sensors (GPS receiver, hydraulic pressure transducer, drum rotation sensor, etc.) and waterproof armored-dome CCTV digital cameras. Suitable technological alternatives (e.g., fast frame photographic systems) that are capable of meeting data needs may be accepted if approved by NMFS.

Electronic Monitoring Data Needs EM system features are determined by program needs and objectives. Program needs will dictate the specific features an EM system must have in order to meet defined objectives. The objectives listed below are not an exhaustive list, but rather, a synopsis of program goals used throughout the study period.

• Identify, count, and assign a catch disposition (kept or discarded) for individual catch items,

• Obtain an estimated length per catch item (required to obtain a weight estimate),

• Obtain an estimated weight per catch item, species, or species group by haul o Individual fish, volumetric weight, scale or tote weight, etc.

• Monitor fishing activity (as defined by program needs),

• Monitor regulatory compliance (as defined by program needs), and

• Verify area fished.

The purpose of this paper is to identify specific product features needed to meet primary objectives for fisheries management data. Product features presented in this report include those identified during the NEFSC study as an example of characteristics that may be needed for a catch share monitoring program.

Additional product features may be needed for an operational program or will vary depending on the program data needs and objectives.

• Distinguish and identify commercially important species and/or common bycatch in the Northeast Multispecies Fishery.

• Maintain a running count of individual fish during a trip by species (trip duration estimated 1-15 days total).

Functional Requirements An EM system consists of two major elements; hardware and software. The proposed specifications are based on the general EM program objectives included above for a catch share monitoring program.

Incorporating more defined objectives (i.e., data timelines or turnaround, volumetric measurements, etc.)

may negate or alter some of the specifications listed below. The standards below are set as minimum requirements, as advancements in technology improve these standards may be amended. Specifications listed in this document as “preferred” are not required.

Hardware

I. General

• Hardware should be adaptable and transferrable in application to enable deployment on a variety of fishing vessels (size, gear, target species).

• Hardware should be easily maintained by the vessel crew and spare parts readily available in close proximity to the vessel port.

• Hardware, including but not limited to wires, cameras, control box, and sensors, shall be adequately shielded to prevent radio frequency interference (RFI) with Vessel Monitoring System (VMS) units (http://www.nmfs.noaa.gov/ole/docs/2015/040815_noaa_fisheries_service_type.pdf).

• All vessel electronics need to work together simultaneously.

II. Power

• Ability to run off DC or AC power supply, inverters, or generators.

o Power draw should be minimal (with 8 digital cameras, a maximum of 120 watts).

o Power wires should be resistant to damage, water, weather, sun, etc.

o Provide safeguards to retain data in the event of electrical failure or power spikes.

o Vessels interested in using EM should note the power requirements of the system.

III. Vessel Data Storage

• The system should have sufficient data storage capacity to store all video and sensor data for an entire month (minimum of 500 gigabytes storage capacity). Each frame of stored image data should record a datetime stamp in the specified format1.

o Data storage hardware should be resistant to damage and data loss.

1 Datetime: values are represented as a ten-digit number in the format YYMMDDHH24MI. YY = two digit year, MM = two digit month, DD = two digit day of the month, HH = two digit hour using 24 hour clock, MI = two digit minutes. All values are two digits padded with zeros. Full datetime must be a ten-digit numeric value. Dates and times should be determined based on local time on the fishing vessels at the time of fishing activity.

RFQ EA133F-16-RQ-1822

• The system must include a means of removing data from the EM unit, such as;

o At least two external USB ports, o Removable storage device (e.g., hard drive) approved by NMFS or, o Other approved means of transferring data approved by NMFS.

IV. Cameras and Review

• Cameras (number of cameras will vary by vessel and program needs) should be enclosed in a waterproof armored-dome. Cameras should have a minimum IP rating of 66.

• Cameras should be capable of point-to-point or point-to-multipoint transmission (not openly transmitted) on all monitors.

• All cameras within a system should operate in synchronization for review and analyses purposes.

Synchronized playback should occur with a 10 second timeframe.

• Cameras should be capable of operating continuously to meet data needs.

• Each camera should be easily surface mounted on vessels and provide manually adjustable viewing positions.

• Each camera should be compatible with a range of fixed focal length lenses to enable swapping of lenses or have varifocal lenses to achieve monitoring goals.

• Cameras must provide the option to produce still images for enhanced species identification and measurement.

• Cameras must be able to be triggered to record fishing, catch handling, transiting or any other vessel activity.

• Camera resolution must be a minimum of 1,280 x 720 (720p) for enhanced identification and measurement during video review.

NMFS strongly encourages the use of higher resolutions than those described above whenever possible.

• Each camera must record at a speed of no less than 15 unique frames per second when the use of a video monitoring system is required.

• Some manufacturers use proprietary compression formats that require the use of proprietary software in order to view the video sequence or images. Use of such software can prevent or hinder law enforcement from viewing or otherwise accessing these images. If such software is used, then steps must be taken to ensure that law enforcement will be able to access them when needed.

• Cameras must have auto-iris capabilities and produce color footage with the ability to revert to black and white video output when light levels become too low for color recognition.

o Cameras must be capable of functioning during low light conditions to account for nighttime fishing activity. “Functioning” is defined as allowing video reviewers to count, identify, and measure individual fish and otherwise account for fishing activity and catch handling.

• Monitors should be appropriate to the vessel size and power supply, such that the monitor size is sufficient for the captain and EM technician to access and evaluate the EM system performance before, during, and after a fishing trip. Power draw by the monitor should be such that it will not overburden the vessel's power supply. The video monitor must:

o Display all cameras simultaneously;

o Operate at all times, including when fish are handled or sorted; and o Be securely mounted and readily accessible to the EM technician and captain and crew.

• If required, measurement grids (discard chute, sorting table panel, etc.) should be designed and tailored to each gear type and vessel size, compatible with common species caught by the vessel.

RFQ EA133F-16-RQ-1822

• Measurement grids should be capable of calibration (through the EM software) to ensure data accuracy and precision.

o Grids should be constructed of a material that allows catch to flow smoothly, without snagging.

o Grids should be fixed in place during fishing activity and be resilient to standard vessel motions.

o Grids should be of an appropriate size and shape and not impede or hamper normal fishing practices.

• All components (including cameras, sensors, control box, and wiring) of a robust system must be capable of starting up and functioning during extreme weather conditions (temperatures in the Northeast range from -7 to 29 degrees Celsius) wherever and whenever groundfish vessels are actively fishing. The Northeast groundfish fleet includes a number of small boats with semi-enclosed wheelhouses. Spray, condensation, cold, and heat occasionally enter the wheelhouse on these vessels.
