This data contains the logbook records from fishery vessels reporting pearlside, Maurolicus muelleri, from 2009 to 2011. The data contains all data registered in the logbook, from catch date to position, pearlside catch and by-catch by tow with pelagic trawls. Specifics of the trawls used (mostly modified capelin trawls) are indicated, e.g. circumference and mesh size. The location of the catches, the date of capture, the species IDs in the database of the Marine and Freshwater Research Institute of Iceland, the Latin, English and Icelandic names of species, and the tow time are recorded, too. Fishery vessel IDs are randomized due to data protection and are similar to the IDs mentioned in the associated biological data files for M. muelleri called “Biological data Maurolicus muelleri-Fisheries data and B3-2010 survey”. Associated biological information contains length distribution per trawl stations, trawl information, date, location, length, weight and age of the fish when available.
