dataset shows the distribution of fishing effort by fishing vessels according
to the gear type used. Fishing effort is defined as the time spent engaged in
fishing operations or time spent at sea, this time may be multiplied by a
measure of fishing capacity, e.g. engine power. In this dataset fishing effort
is measured as average hours spent actively fishing per kilometre square, per
year. Data from years 2014 to 2018 was used to produce this data product for
the Marine Institute publication the “Atlas of Commercial Fisheries around
Ireland, third edition“ (</span><span style='color:rgb(76, 76, 76);'><a href='https://oar.marine.ie/handle/10793/1432' rel='nofollow ugc'><span style='color:#337AB7;'>https://oar.marine.ie/handle/10793/1432</span></a></span><span style='color:rgb(51, 51, 51);'>).</span></font></p>

</span><span style='color:rgb(51, 51, 51);'>Effort for offshore fisheries is
based on the following 2 primary data types - data on vessel positioning and
data on gear types used:</span><span style='color:rgb(76, 76, 76);'><br />
</span><span style='color:rgb(51, 51, 51);'>Vessel Monitoring Systems (VMS)
supplied by the Irish Naval Service provide geographical position and speed of
vessel at intervals of two hours or less (Commission Regulation (EC) No.
2244/2003). The data are available for all EU vessels of 12m and larger,
operating inside the Irish EEZ; outside this zone only Irish VMS data are
routinely available. VMS do not record whether a vessel is fishing, steaming or
inactive.</span><span style='color:rgb(76, 76, 76);'><br />
<br />
</span><span style='color:rgb(51, 51, 51);'>Logbooks collected by the
Sea-Fisheries Protection Authority and supplied by the Department of
Agriculture, Food &amp; the Marine were the primary data source for information
on landings and gear types used by Irish vessels. EU Fleet Register obtained
from the EU fleet register provides information for non-Irish vessels and
for Irish vessels for which the gear was not known from the logbooks. Note that
if vessels use more than one gear, it is possible that the gear type assigned
to them was not the one that was actually used. The fishing gear data was
classified into eight main groups: demersal otter trawls; beam trawls; demersal
seines; gill and trammel nets; longlines; dredges; pots and pelagic trawls.</span><span style='color:rgb(76, 76, 76);'><br />
<br />
</span><span style='color:rgb(51, 51, 51);'>The VMS data was analysed using the
approach described by Gerritsen and Lordan (IJMS 68(1)). This approach assigns
effort to each of the VMS data points. The effort of a VMS data point is
defined as the time interval since the previous data point. Next the data are filtered
for fishing activity using speed criteria, vessels were assumed to be actively
fishing if their speed fell within a certain range (depending on the fishing
gear used). The points that remain are then aggregated into a spatial grid to
produce a raster dataset showing fishing effort (in hours) per kilometre square
per year for each gear type group. The data is available for all countries
combined and for Irish vessels only.</span></font></p>"""@en ;
