Are thornyhead centroids too shallow #85

Look at thorny head depth range on FishBaste and look at raw data from the west coast survey and see how they compare.

According to FishBase, shortspine thornyhead live between 17-1600 m, usually around 91m. Longspine are at 201-1757 m and Broadband are 257-1537m.

According to OceanAdapt, all of the plots for fish in the genus Sebastolobus in the Aleutians, Gulf of Alaska, and both West Coast surveys are deeper than 200m. The deepest trawl of any species reported in the BY_SPECIES_DATA is ~400m so the deeper ranges of the thornyheads are outside the scope of this survey.

Dear Michelle and Malin,

The NOAA NWFSC FRAMD conducts a survey that collects trawl data down to 1200 m, that could be used to expand the US West Coast groundfish data. I imagine the same issue likely affects a lot of the other deepwater continental margin species here as well, if the current data only pulls from 400 m and shallower.

Best,
