Polyvalent vessels M Description of segments A Polyvalent small-scale vessels without engine – All vessels less than 12 metres in length overall (LOA) without an engine (wind or propulsion). B Polyvalent small-scale vessels with engine less than 6 m – All vessels under 6 metres in length overall (LOA) with engine. C Polyvalent small-scale vessels with engine between 6 and 12 m – All vessels between 6 and 12 metres in length overall (LOA) with engine, that use different gear during the year without clear predominance of one of them or that use a gear not considered in this classification. D Trawlers less than 12 m – All vessels less than 12 metres in length overall (LOA) allocating more than 50 % of their effort operating with a demersal trawl.

E Trawlers between 12 and 24 m – All vessels, between 12 and 24 metres in length overall (LOA) allocating more than 50 % of their effort operating with a demersal trawl. F Trawlers longer than 24 m – All vessels over 24 metres in length overall (LOA), allocating more than 50 % of their effort operating with a demersal trawl. G Purse Seiners between 6 and 12 m – All vessels between 6 and 12 m in length overall (LOA), allocating more than 50 % of their effort operating with a purse seine. H Purse Seiners longer than 12 m – All vessels over 12 m in length overall (LOA), allocating more than 50 % of their effort operating with a purse seine, excluding those using a tuna seine during any time of the year. I Longliners longer than 6 m – All vessels over 6 m in length overall (LOA), allocating more than 50 % of their effort operating with a longline. J Pelagic Trawlers longer than 6 m – All vessels over 6 m in length overall (LOA), allocating more than 50 % of their effort operating with a pelagic trawl. K Tuna seiners – All vessels operating with a Tuna Seine for any length of time during the year.

L Dredgers longer than 6 m – All vessels over 6 m in length overall (LOA), allocating more than 50 % of their effort operating with a dredge. M Polyvalent vessels longer than 12 m – All vessels over 12 metres in length overall (LOA), that use different gear during the year without clear predominance of one of them or that use a gear not considered in this classification. Note: All the cells are open for collecting information. The cells left blank in the above table are considered as unlikely to have a significant population. However, if necessary, it is advisable to merge the information of a ‘blank cell’ with the most appropriate neighbouring ‘grey cell’. (B) Table on measurement of nominal fishing effort
