Abstract:

Simulated spatial and temporal distribution of the numbers and biomass of eight fish species killed due to oil toxicity from 2000-01-01 to 2020-01-01. Numbers and biomass of dead fish are reported on January 1 of each year in each cell of a 421x1021 grid spanning 24°N-31°N and 98°W-81°W. The included species are red grouper, gag grouper, mutton snapper, red snapper, grey triggerfish, vermillion snapper, yellowedge grouper, and tilefish. This dataset is one of a set that uses statistical modeling and machine learning methods to simulate many aspects of fisheries research: example of logbook data from modeled commercial fishing fleets (DOI: 10.7266/n7-nwff-ap81, UDI: R5.x289.000:0001); population size and age data from simulated fish ecology (DOI: 10.7266/n7-scsn-ws67, UDI: R5.x289.000:0002); life history characteristics from a sample of the catch simulated commercial fishery (DOI: 10.7266/n7-bvvg-rz2, UDI: R5.x289.000:0003); spatial distribution of simulated oil-induced fish mortality (DOI: 10.7266/n7-0v4e-v691, UDI: R5.x289.000:0005); spatial fishing effort with handline and longline fishing vessels (DOI: 10.7266/n7-gtwq-5y46, UDI: R5.x289.000:0006); spatial distribution of annual fish (DOI: 10.7266/n7-qf7p-gt16, UDI: R5.x289.000:0007); and annual reported distribution of fish abundance and biomass (DOI: 10.7266/n7-1cb3-8j47, UDI: R5.x289.000:0008).

Purpose:

Fisheries simulation.

Data Parameters and Units:

ID (the identifier for that grid cell, [enum]); longi (longitude of the centroid of the grid cell, [decimal degrees]); lati (latitude of the centroid of the grid cell, [decimal degrees]); predictive index of spatial abundance normalized by its mean [unitless] for red grouper, red snapper, gag grouper, grey triggerfish, vermillion snapper, mutton snapper, tilefish, and yellowedge grouper.
