Legal action against ocean fishing
From ANIMAL PEOPLE, May 2003:
U.S. District Judge Thelton Henderson on April 10 held for
the fourth time in 13 years that 1988 amendments to the 1972 Marine
Mammal Protection Act oblige the U.S. to exclude imports of tuna
netted “on dolphin,” a method often used by foreign fleets because
dolphins and tuna feed on the same fish species and often swim
together. Surrounding feeding dolphins with nets therefore usually
captures tuna–as well as dolphins who do not escape before the nets
close. Henderson in May 1990 banned imports of yellowfin tuna from
Mexico, Venezuela, and Vanuatu. After Congress reinforced the 1990
verdict by introducing “dolphin-safe” labeling, Henderson in January
1992 banned $266 million worth of tuna imports from 30 nations.
