While SeaWorld no longer participates directly in wild captures, plenty of other institutions do. Russian fishermen just recently captured two whales - and it's possible that research like this only helped them.
SeaWorld's orca "research" has been called into question before. While the company says that it has published more than 30 studies specific to killer whales - this statistic is over the past 50 years. This rounds out to an average of 0.6 papers each year. Meanwhile, orca researchers that study whale populations in the wild are churning out papers.
Last week, SeaWorld pledged $10 million towards research on wild orca populations under threat, particularly whales in the Pacific northwest. Ironically, this is the same population that's been struggling to recover after SeaWorld's wild captures in the 1970s and 80s decimated their numbers.
