Seabird Avoidance: The Mingled
Destinies of Seabirds and longliners in the North Pacific
1. A Highly Endangered Species
In 1995 freezer-longliners took two short-tailed albatrosses
on baited hooks. The world population of these birds was
900 at the time - 90% of which nest on a violently active
volcanic island off Japan. The short-tailed albatross
is the most highly endangered seabird in the North Pacific
and is listed under the Endangered Species Act.
2. Immediate Industry Action
The North Pacific Longline Association (NPLA), a member
of the Marine Conservation Alliance (MCA), immediately
searched worldwide for examples of seabird avoidance
regulations. Using CCAMLR (Antarctic) regulations as
a model and drawing on the knowledge of longline fishermen,
the association prepared DRAFT seabird avoidance regulations
and presented them to the North Pacific Fishery Management
Council (NPFMC). The NPFMC voted to implement the regulations
by emergency rule.

3. Cooperative Research
The U.S. Fish and Wildlife Services (USFWS) issued a biological
opinion calling for research to test the effectiveness of
the seabird avoidance regulations. The NPLA joined with the
Washington Sea Grant Program to test seabird avoidance techniques
on vessels participating in the commercial longline fishery
over a period of two years. Millions of hooks were set in
the most extensive experiment of this sort ever undertaken.
Streamer lines suspended behind the vessels and meeting specified
performance standards were found to be 88% to 100% effective
in deterring seabird interactions. The USFWS, the NPFMC, and
NOAA Fisheries also supported this effort. The U.S. Coast
Guard has been most helpful in the publicizing and enforcing
the seabird avoidance regulations.
4. Results
The first seabird avoidance regulations were implemented in
May of 1997. And amended regulations requiring the use of
streamer lines were approved by the NPFMC and implemented
in 2004. The USFWS established a program to supply the fleet
with free streamer lines, and the longline fleet has deployed
them voluntarily. Since the first full year of regulations
the freezer-longliner fleet, which is responsible for most
seabird takes off Alaska, has reduced its take by more than
80%. Employment of internally weighted groundlines is expected
to bring further reductions in the future. The short-tailed
albatross population is growing at nearly its biologically
maximum rate, and has now reached 1,800.
The MCA and NPLA petitioned Congress for
an appropriation to fund the activities of the Short-Tailed
Albatross Recovery Team (START), dedicated to protecting and
delisting the species. This cooperative effort by industry,
academia, and federal agencies stands as a model for managing
protected species.
