International Fisheries; Tuna and Tuna-Like Species in the Eastern Pacific Ocean; Silky Shark Fishing Restrictions and Fish Aggregating Device Data Collection and Identification

NMFS is issuing regulations under the Tuna Conventions Act to implement certain provisions of two Resolutions adopted by the Inter- American Tropical Tuna Commission (IATTC) in 2016: Resolution C-16-01 (Collection and Analyses of Data On Fish-Aggregating Devices) and Resolution C-16-06 (Conservation Measures for Shark Species, with Special Emphasis on the Silky Shark (Carcharhinus Falciformis) for the Years 2017, 2018, and 2019). Per Resolution C-16-01, these regulations require the owner or operator of a U.S. purse seine vessel to ensure characters of a unique code be marked indelibly on each fish aggregating device (FAD) deployed or modified on or after January 1, 2017, in the IATTC Convention Area. The vessel owner or operator must record and submit information about the FAD, as described in Annex I of Resolution C-16-01. Per Resolution C-16-06, these regulations prohibit the owner or operator of a U.S. purse seine vessel from retaining on board, transshipping, landing, or storing, in part or whole, carcasses of silky sharks caught by purse-seine vessels in the IATTC Convention Area. These regulations also provide limits on the retained catch of silky sharks caught in the IATTC Convention Area. This rule is necessary for the United States to satisfy its obligations as a member of the IATTC.
