The environmental organisation, Earth Island Institute, wants the Solomon Islands government to ban dolphin trading.
The institute's Mark Berman has just returned to the United States from a visit to Solomon Islands, where he says a deal's been struck with the people of Fanalei and Walande in south Malaita to stop their annual slaughter of 2000 dolphins.
This comes after a trader in the mammals who's been called the darth vader of dolphins, Christopher Porter, announced he's leaving the business and intends to release his remaining animals.
But Mr Berman says there's no point in releasing them until all dolphin trading has stopped.
"The whole thing about dolphins is out of control, there's no oversight by the government so anyone can just go catch a dolphin as if it were a goldfish. The inhumanity to the treatment of these dolphins is just deplorable by these dolphin catchers."
