Very low risk

The management of the western Atlantic skipjack tuna is low risk. There are no management measures in place specific to skipjack. However, with the current stable levels of catch, and status of the stock exploited within safe biological limits (see stock status heading), the current management regime is considered to be adequate precautionary management. Skipjack are likely obtain some protection through measures in place for other tuna species.
The bycatch in the skipjack tuna western Atlantic troll and pole fishery has been scored a low risk. Bycatch and discards in troll and pole fisheries typically makes up a small proportion of the total catch (Kellher 2005). However, baitfish are often used in these fisheries. The ratio of tuna to baitfish is around 30:1 (Gillet 2012).
The habitat impact of the skipjack tuna western Atlantic Ocean pelagic troll and pole fishery has been scored as low impact. This is because there is the potential for hooks to contact bottom habitats. Although in tuna fisheries, which target fish in open waters, this is a very minor concern.
