Are seabirds really of conservation concern or is this an animal rights issue?

Some global stats BLI – 300 000 seabird mortalities annually 19 of 21 species of albatross threatened with extinction

Albatrosses at South Georgia are decreasing at an alarming rate! Number of pairs Data courtesy British Antarctic Survey Wandering albatrosses: 1960’s–1997: 1 % per year 1997–2004: 4.5 % per year 1960s 1200 1600 2000 198019902000 2005 Grey-headed albatrosses: 2.4 % per year 19701975198019851990199520002005 100 200 300 400 500 Black-browed albatrosses: 4.8 % per year 19701975198019851990199520002005 0 100 200

Why are seabirds vulnerable?
9
Long-lived Long-lived Delayed sexual maturity Delayed sexual maturity Slow breeding Slow breeding High adult survival rates High adult survival rates VULNERAB LE to MORTALITY MORTALITY
10
South Georgia Winter 99 Breeding 00 Winter 00 Grey-headed Albatross tracks TRAVEL LARGE DISTANCES
11
Spectacled Petrel - Critically endangered Total population: 3000 pairs at one island SMALL POPULATIONS
12
Their life history strategy makes them vulnerable to even small increases in adult mortality
13
The fishers perspective… In some cases events are rare – In some cases events are rare – complicates perceptions regarding the need for conservation E.g. for every seabird taken, 100s of fish are caught E.g. for every seabird taken, 100s of fish are caught Many sets don’t catch any Many sets don’t catch any Often large no’s around vessel Often large no’s around vessel BUT SMALL NUMBERS ADD UP WHEN WE CONSIDER THE ENTIRE FLEET OR REGION BUT SMALL NUMBERS ADD UP WHEN WE CONSIDER THE ENTIRE FLEET OR REGION
14
Is the Atlantic important for the conservation of these species?
15
41 species known to interact with ICCAT fisheries 41 species known to interact with ICCAT fisheries –1 Critically endangered –7 Endangered –9 Vulnerable 35% of breeding albatrosses occur in the Atlantic 35% of breeding albatrosses occur in the Atlantic
16
Are there solutions?
17
Set lines at night Albatrosses feed mainly during the day Some smaller petrel species not conserved
18
Put enough weights onto line
19
Use bird-scaring (tori) lines Bycatch rate reduced by up to 80%
21
10m Mitigation measures
22
What are the benefits to fisherman? Protecting marine life will protect the food chain Protecting the food chain will protect your livelihood Baits lost to birds and turtles cannot catch fish!
