and places 28 licenses for the entire EU.
These are likely used by fishing boats, such as purse seiners
and ring netters, which were found inside prohibited areas in municipal waters.
Concerning the activity of purse seiners
, the highest fishing effort is observed in July (Kavadas and Maina 2012) and coincides with egg hatching and the early chick-rearing phase of Scopoli's shearwater.
liza was considered an accessory resource occupying the 20th position in the list of species catch by purse seiners
and represented less than 0.5% of the annual amount of fish landed by purse seiners
off Santa Catarina waters (Schwingel & Occhialini, 2003).
Taking advantage of this associative behavior, tropical tuna purse seiners
regularly deploy drifting, manmade floating objects, also called drifting fish aggregating devices (DFADs), to facilitate their catch of skipjack (Katsuwonus pelarais), yellowfin (Thunnus albacares) and bigeye (Thunnus obesus) tunas.

Ignoring the PNA rules that all fishing licenses come under the group's vessel/day arrangement, Kiribati signed a side deal with a fleet of four giant Spanish purse seiners
. Not only did the deal not involve any limits to the number of days fished or the amount of fish caught, but a Greenpeace estimate of the probable catch found that the per-day fee would be $3,600, just over half the going rate.
The duration of the protocol will be three years and will allow 27 purse seiners
and eight pole and line vessels to fish for tuna and other migratory species in Gabonese waters divided as follows: France 12 tuna purse seiners
and one pole and line tuna vessel; Spain 15 tuna purse seiners
and seven pole and line tuna vessels.
