Subject: Complete Longline Observer Data Submission under Resolution C-19-08

Dear Dr. Compeán:

The United States is submitting this follow up letter pursuant to IATTC Resolution C-19-08, Resolution on Scientific Observers for Longline Vessels. Attached is a Microsoft Excel workbook that contains complete observer data and fishing effort information for 2019, per Annex A of the Resolution. The Annex A fleet data section included in the prior submission, sent to the IATTC on March 31, 2020, did not include unobserved trips, as we did not yet have access to that data. The Annex A species data and Annex B operational data sections were not affected by the addition of the new data, and thus remain unchanged from the original submission. Please contact William Stahnke at (562) 980-4088 or [email protected] with any questions.

Sincerely,

Lyle Enriquez Highly Migratory Species Branch Chief

United States Summary of 2018 Observer Data per Resolution C-11-08, Resolution on Scientific Observers for Longline Vessels

This summary is submitted pursuant to Inter-American Tropical Tuna Commission (IATTC) Resolution C-11-08, Resolution on Scientific Observers for Longline Vessels. Scientific observers are required on 100 percent of all shallow-set longline trips targeting swordfish and at least 20 percent of all deep-set longline trips targeting bigeye tuna, regardless of vessel size. The observer data in this report contain only data from longline vessels based in , which comprise over 99 percent of the U.S. pelagic longline fleet. The tables below are summaries of observer data for sets that occurred on vessels greater than 20 meters (m) in length in the IATTC Convention Area in 2018, based on begin-set position and haul date.

Sets (i.e., fishing days1) A total of 267 shallow sets by vessels >20m in length were observed in the IATTC Convention Area in 2018. One-hundred percent of shallow sets (fishing days) in the IATTC Convention Area were observed. A total of 735 deep sets by vessels >20m in length were observed in the IATTC Convention Area in 2018. The percent of deep sets (fishing days) in the IATTC Convention Area by vessels >20m are not available at this time but will be updated upon receipt.

Sea Turtle Release United States regulations require fishermen to release all sea turtles, alive or dead. There is no record of fishermen not complying with these regulations in 2018.

Hook Type and Quantity Both the shallow-set and deep-set longline fisheries used the following hook types:

1. Offset round circle: a hook with either the point or point and barb that curves towards the shank, but is also bent so that the point and shank do not lay in the same plane. The hook has no flat edges along its shank. In 2018, these hooks were only used by the observed deep set longline vessels >20m - sizes 15/0-16/0.

2. Offset flat circle: a hook with either the point or point and barb that curves towards the shank, but is also bent so that the point and shank do not lay in the same plane. The hook will have, at least, some portion of its shank flattened. In 2018, these hooks were used in observed shallow and deep sets by longline vessels >20m. Shallow sets used size 18/0 hooks and deep sets used sizes 14/0-16/0.

In 2018, the number of hooks per set in the shallow-set longline fishery ranged in quantity from 429 to 1,590. The number of hooks per set in the deep-set longline fishery ranged from 211 to 3,836; however, the minimum number may be an outlier, with a more representative minimum being 936.

1 Each set is effectively one fishing day with a single set typically completed within 24 hours of starting.

United States Summary of 2017 Observer Data per Resolution C-11-08, Resolution on Scientific Observers for Longline Vessels1 This summary is submitted pursuant to Inter-American Tropical Tuna Commission (IATTC) Resolution C-11-08, Resolution on Scientific Observers for Longline Vessels. Through an amendment to the Magnuson-Stevens Fishery Conservation and Management Act, scientific observers are required on 100 percent of all shallow-set longline trips targeting swordfish and at least 20 percent of all deep-set longline trips targeting bigeye tuna. The observer data in this report contain only data from longline vessels based in Hawaii, which comprise over 99 percent of the U.S. pelagic longline fleet. The tables below are summaries of observer data for sets that occurred in the IATTC Convention Area in 2017, based on begin-set position and haul date. Sets (i.e., fishing days) A total of 409 shallow sets occurred in the IATTC Convention Area. Each set is effectively one fishing day with a single set typically completed within 24 hours of starting. One-hundred percent of shallow sets (fishing days) in the IATTC Convention Area were observed. The total number of deep sets and the percent of deep sets observed are not available at this time but will be updated upon receipt. Sea Turtle Release United States regulations require fishermen to release all sea turtles, alive or dead. There is no record of fishermen not complying with these regulations in 2017. Hook Type and Quantity Both the shallow-set and deep-set longline fisheries used the following hook types: 1. Offset round circle: a hook with either the point or point and barb that curves towards the shank, but is also bent so that the point and shank do not lay in the same plane. The hook has no flat edges along its shank. 2. Offset flat circle: a hook with either the point or point and barb that curves towards the shank, but is also bent so that the point and shank do not lay in the same plane. The hook will have, at least, some portion of its shank flattened.

In 2017, the number of hooks per set in the shallow-set longline fishery ranged in quantity from 97 to 1,628; however, the minimum number may be an outlier, with a more representative minimum being 423. The number of hooks per set in the deep-set longline fishery ranged from 520 to 3,642; however, the minimum number may be an outlier, with a more representative minimum being 1,207.

1In its letter dated 23 April 2018, the United States stressed that this “report that summarizes observer data and provides information on effort (i.e., fishing days); these data are preliminary and subject to change. The enclosed report does not include the total and percent observed effort in deep-set longline fleet because those data have not yet been summarized for 2017. When they are complete, the National Fisheries Service will submit an update to the report. The raw data (set-level) for 2013-2016, and for 2017, were submitted in January and March, respectively, as agreed by the parties at the 8th meeting of the SAC and 92nd meeting of the IATTC.”

Catch Species Composition Below are tables summarizing the species composition of animals caught in shallow-set and deep-set longline fisheries (Tables 1 to 6). A total of 13,870 and 30,887 individual fish, marine mammals, sea turtles, and seabirds were observed caught in 2016 in the shallow-set and deep-set longline fisheries, respectively.
