A fleet segment is the combination of a particular fishing technique category and a vessel length category (see tables below).
|DFN||=||Drift and/or fixed netters|
|DTS||=||Demersal trawlers and/or demersal seiners|
|FPO||=||Vessels using pots and/or traps|
|HOK||=||Vessels using hooks|
|MGO||=||Vessel using other active gears|
|MGP||=||Vessels using polyvalent active gears only|
|PG||=||Vessels using passive gears only for vessels < 12m|
|PGO||=||Vessels using other passive gears|
|PGP||=||Vessels using polyvalent passive gears only|
|PMP||=||Vessels using active and passive gears|
|VL0006||=||Vessel less that 6 meters in length. *For Supra region 2 only.|
|VL0010||=||Vessel between 0 meters and 10 meters in length. **For Supra region 1 and 3 only.|
|VL0612||=||Vessel between 6 meters and 12 meters in length. *For Supra region 2 only.|
|VL1012||=||Vessel between 10 meters and 12 meters in length. **For Supra region 1 and 3 only.|
|VL1218||=||Vessel between 12 meters and 18 meters in length. All regions.|
|VL1824||=||Vessel between 18 meters and 24 meters in length. All regions.|
|VL2440||=||Vessel between 24 meters and 40 meters in length. All regions.|
|VL40XX||=||Vessel greater than 40 meters in length. All regions.|
Fleet segmentation by region:
|Vessel_Length classes (LOA)(1)|
|0-06m ; 0-10m||6-12m ; 10-12m||12-18m||18-24m||24-40m||40 or larger|
(1) For vessels less than 12 metres in the Mediterranean Sea and the Black sea, the length categories are 0-< 6, 6-< 12 metres. For all other regions, the length categories are defined as 0-< 10, 10-< 12 metres.
(2) Vessels less than 12 metres using passive gears in the Mediterranean Sea and the Black Sea may be disaggregated by gear type. Without disaggregation, the gear code is 'PG'.
(3) Non active vessels. Only data on capacity and capital value is required for inactive vessels.
