Whale Shark Monitoring
The Western Australian Department of Environment and Conservation together with the Ningaloo whale shark tourism industry have been closely involved with monitoring whale sharks at Ningaloo Marine Park since 1995. The following monitoring is being carried out: - Whale shark tourism industry logbooks - Spotter plane logbooks and GPS track and waypoint data collection - Aerial behavioural observations Data from tour operator logbooks has proven useful in gaining an understanding of trends in the whale shark industry. Based on logbook data, the total number of whale shark interactions during the paying season (1st April to 31st May) has reduced by around 36% from 1996 to 2007. This figure needs to be taken with caution as analysis of spotter plane data indicates a shifting peak of whale shark observations to outside the paying season into the months of June and July. Full season data in logbooks was only collected from 2004 onwards. Whale shark interaction success rate for tours has declined slightly, averaging approximately 80%. Sex ratio ranged from 2:1 to 4:1 males:females. Analysis of observed length estimates indicates a 1.5m reduction in mean length. Whale sharks observed showed a trend for direction of travel along the north-south gradient with a greater northward bound favour. Anecdotal reports that whale shark numbers are declining are not supported by an analysis of the aerial spotter plane data. Aerial behavioural observation work was initiated in 2007 as an alternative method of collecting behavioural response to interactions other than the industry logbooks.

Ningaloo Marine Park Monitoring Program
공공데이터포털
Benthic lifeform and substrate monitoring data from 1993 onwards, held in the RM_VPOINT table of the NMPMP database. Percentage cover of different substrate types and benthic organisms (particularly corals), identified to benthic group or lifeform level. Videos are made along fixed transects and data is analysed from stills on a large video screen halted at specified time intervals. The AIMS LTMP monitors about 50 selected reefs throughout the Great Barrier Reef. Transects are recorded at 3 sites per reef, and 3 50m transects per site. Visual transect data is stored in a separate table, and described as a separate but related dataset.
Observer Scanning System (OBSCAN)
공공데이터포털
Paper logs are the primary data collection tool used by observers of the Northeast Fisheries Observer Program deployed on commercial fishing vessels. After the data collected on the paper are entered into a database, the paper logs are scanned for each trip. After all trips for a calendar year are scanned, they are archived at the National Archives and Records Administration.

Overflight monitoring observations of recreational fishing activity on the South Coast of British Columbia
공공데이터포털
These data provide the coordinates of recreational fishing boats sighted from aerial surveys as part of the Fisheries and Oceans Canada South Coast Area Creel program to estimate recreational fishing catch and effort. The recreational boats are classed as 1) fishing, or 2) running. Aerial surveys are conducted from float planes approximately every 3-7 days during the peak fishing season according to weather and resource availability. Digitization of the boat sightings began in recent years and complete datasets are available beginning in 2021. The aerial surveys provide a snaphot of recreational fishing effort limited to the short interval the plane was passing overhead and should not be construed as total fishing effort. Due to the volume of fishing activity in some areas, each point represents one or more boats in approximately the same area. The resolution of the observation points is decided by the survey observer. Locations and boat counts are subject to observer error. The total number of boats observed is related to the number and timing of successful aerial surveys which vary seasonally and regionally. As such, results are not directly comparable across regions or time periods.

Electronic Monitoring in the Pacific Islands Longline Fisheries Data
공공데이터포털
Electronic monitoring (EM) data are collected aboard Hawaii longline vessels (shallow- and deep-set) participating in a pre-implementation voluntary program. These data include video collected during hauling of fishing gear and sensor data collected throughout the fishing trip. Selected EM trips are reviewed for the detection of catch and bycatch species with identification performed to species or species groups.Â
