title: Data for: Marine fish movement: home range sizes for commercially relevant species

description: Estimates of home range sizes for marine fishes are essential for
 designing and assessing the effects of spatial wildlife conservation
 policies and management interventions. However, in situ studies of marine
 species movement are challenging and often expensive, resulting in a
 paucity of data on the home range size of the vast majority of marine
 fishes. Here, we develop a set of new datasets, which we have collectively
 named Marine Fish Movement, that synthesises published empirically
 evaluated home ranges reported for adult marine fishes that interact with
 fisheries and leverage these data to estimate home range sizes for
 unstudied species. The empirical data contain estimated home range sizes
 (km2) for 193 species across 63 family groups from 179 studies published
 between 1971 and 2022. We use a Random Forest regression model to estimate
 home range sizes (km2) for 664 fished marine species currently lacking
 home range estimates. Marine Fish Movement can inform spatial
 interventions including the design and management of marine protected
 areas and dynamic fisheries management to meet sustainability goals.

 Estimates of home range sizes for marine fishes are essential for
 designing and assessing the effects of spatial wildlife conservation
 policies and management interventions. However, in situ studies of marine
 species are challenging and often expensive, resulting in a paucity of
 data on the home range size of the vast majority of marine fishes. Here,
 we develop a set of new datasets, which we collectively refer to as Marine
 Fish Movement, that synthesizes published empirically evaluated home
 ranges reported for adult marine fishes that interact with fisheries
 (either as a target or incidental catch) and leverage these data to
 estimate home range sizes for unstudied species. The empirical data
 contain estimated home range sizes (km2) for 185 species across 61 family
 groups from 170 studies published between 1971 and 2022. We use a Random
 Forest regression model to estimate home range sizes (km2) for 667 fished
 marine species currently lacking home range estimates. Marine Fish
 Movement can inform spatial management strategies including the design and
 administration of marine protected areas and dynamic fisheries management
 to meet sustainability goals. --- ## SHARING/ACCESS INFORMATION

 (1) empirical_homeranges.csv is part of the Marine Fish Movement dataset
 (reference forthcoming). It contains estimated home range sizes (km2) for
 185 species across 61 family groups from 170 studies published between
 1971 and 2022 collected via a targeted literature review of commercially
 relevant marine fishes. The data file contains the following information:
 Number of variables: 13 Number of cases/rows: 221 Variable list/column
 headings: * species: scientific name for species (Genus species) *
 common_name: common name for species in English * family: scientific
 family designation for species * homerange: home range size (in km^2;
 calculated from individual observations if mean was not reported) * hr_sd:
 standard deviation of home range sizes in study (calculated from
 individual observations if available) * hr_percent: % utilization
 distribution (75, 80, 95, etc.) * hr_type: "KUD" for kernel
 utilization distribution, might be referred to as a UD; "MCP"
 for minimum convex polygon; "GEO" for other geometric estimation
 technique. Identifying the analytical technique used to estimate the home
 range * method: data collection method (values: direct observation,
 mark-recapture, telemetry. Identifying the observation method used to
 measure a home range; note that telemetry refers to satellite, acoustic,
 and radio telemetry) * n_ind: number of individuals reported in study (if
 no value was given, recorded as 1 for conservative estimate in weighted
 geometric mean calculation for species) * study_duration: number of days
 of study (midpoint of range (or mean if available - specified), rounded up
 to nearest whole day) * location: descriptive location of study (country,
 ocean, region, etc.) * ref: source reference for the value * notes: notes
 regarding data (2) movement_classification.csv is part of the Marine Fish
 Movement dataset (reference forthcoming). It contains movement keywords
 and a categorical classifier (low, medium, high) for 701 commercially
 relevant marine fishes. Number of variables: 8 Number of cases/rows: 701
 Variable list/column headings: * species: scientific name for species
 (Genus species) * movement_classifier: low/medium/high categorical
 movement based on keywords (see Table 2 in the companion publication) *
 movement_keyword: keyword from FishBase/FAO/IUCN search (see Table 2 in
 the companion publication) * source: data source for movement_keyword (FB
 = FishBase, FAO = Food and Agriculture Association, IUCN = International
 Union for Conservation of Nature, REF = listed reference) * notes: notes
 on species from data source * alt_speces: alternate scientific name for
 species (3) homerange_rf_predictions.csv is part of the Marine Fish
 Movement dataset (reference forthcoming). It contains estimated home range
 sizes (km2) for 667 fished marine species that lack empirical home range
