NMFS has determined that the daily Highly Migratory Species (HMS) Angling category retention limits for Atlantic bluefin tuna (BFT) should be adjusted to maximize the usefulness of the information obtained from catches for biological sampling. Vessels permitted in the HMS Angling and HMS Charter/Headboat categories are eligible to land BFT under the HMS Angling category quota. Therefore, NMFS adjusts the daily BFT retention limits for the HMS Angling category quota to allow landing of school BFT in North Carolina during the three-week period from March 24, 2007, through April 15, 2007, as specified in the SUPPLEMENTARY INFORMATION section of this document. This action is intended to provide scientific data that would enhance future recreational fishing opportunities for the HMS Angling and HMS Charter/ Headboat categories, while minimizing the risk of an overharvest of the HMS Angling category BFT quota.
