(a) States should ensure that data are collected from vessels flying their flag on fishing activities according to the operational characteristics of each fishing method (e.g., each individual tow for trawl, each set for long-line and purse-seine, each school fished for pole-and-line and each day fished for troll) and in sufficient detail to facilitate effective stock assessment;

More than one codline may be used per trawl.

catch data in nominal catch weight and effort data in fishing days (purse seine, baitboat, troll, drift nets) should be provided to IOTC by 1° grid area and month strata.

all vessels exceeding an overall length of 12 metres which are authorised to fish in the 25 mile management zone and which comprise bottom trawlers, vessels fishing with "lampara" purse seines, vessels fishing for lampuki with FADs and vessels fishing with large pelagic purse seines and industrial longlines for tuna and other highly migratory species will be included on a list.

Considering that size data are of key importance for most tuna stock assessment, length data, including the total number of fish measured, should be routinely submitted to the IOTC on a 5° grid area and month basis, by gear and fishing mode (e.g. free/log schools for the purse seiners).

Surrounding nets (purse seines)

Pelagic trawl and purse seines

Trawlers and purse seiners

Small purse seiners

Trawlers, purse seiners

Tuna purse seiners

Purse seiners and pelagic trawlers

This minimum limit may be reduced from 12 metres to six metres for vessels fishing otherwise than by trawl or purse seine and operated by persons whose main activity is fishing.

"set" is the act of deploying and retrieving the purse seine in order to catch tuna;

in the case of purse seines, the main or bottom wire is unschackled from the seine.

This gate or other device must be easily opened and closed and must be open only for casting the net or for hauling it in.

This gate or other device must be easily opened and closed, preferably by remote control, and must be open only for casting the net or for hauling it in.

catch data in nominal catch weight and effort data in fishing days (purse seine, baitboat, troll, drift nets) should be provided to IOTC by 1° grid area and month strata.

the vessel does not simultaneously carry or use on board either towed gear of mesh size less than 70 millimetres or one or more purse seines or similar fishing gears;

Trawling and purse seining for mackerel, sprat and herring shall be prohibited in the Skagerrak from Saturday midnight to Sunday midnight and in the Kattegat from Friday midnight to Sunday midnight.

Ban on the use of purse seines for catching tropical tuna (skipjack, bigeye and longfinned tuna) in waters under the sovereignty or jurisdiction of Portugal in ICES area X, north of latitude 36° 30′

On stern trawlers with ramps, the upper part of the ramp must be fitted with a gate or other means of securing it of the same height as the bulwarks or other adjacent means, to protect workers from the risk of falling into the ramp.

On stern trawlers with ramps, the ramp must be fitted with a gate or other means of securing it of the same height as the bulwarks or other adjacent means, to protect workers from the risk of falling into the ramp.

The retention on board of any quantity of herring, mackerel or sprat caught using trawls or purse seines between Saturday midnight and Sunday midnight in the Skagerrak, and between Friday midnight and Sunday midnight in the Kattegat shall be prohibited.

Considering that size data are of key importance for most tuna stock assessment, length data, including the total number of fish measured, should be routinely submitted to the IOTC on a 5° grid area and month basis, by gear and fishing mode (e.g. free/log schools for the purse seiners).

It shall be prohibited to retain on board any quantity of skipjack, bigeye or yellowfin tuna which are caught using purse seines in waters under the sovereignty or jurisdiction of Portugal in ICES subarea X north of 36°30' N or in CECAF areas north of 31° N and east of 17°30' W, or to fish for the said species in the said areas with the said gears.

whereas part of the coastal zone should be reserved for the most selective gear used by small-scale fishermen, whereas, notwithstanding the geographical scope of Council Regulation (EEC) No 3094/86 of 7 October 1986 laying down certain technical measures for the conservation of fishery resources (4), the provisions of that Regulation concerning drifting gill nets and purse seines are already applicable in the Mediterranean;
