I've always gotten the impression that the "do your homework" is in reference to the Blackfish documentary.
Same here. It has always been Blackfish that Pete has ranted about, not the captivity issue itself.
Sorry, but the content does not back that up. While the reference to "research" and "homework" was made in the context of the documentary itself, you have to dive deeper to see what it is that he is saying was deceptive. Here is the monologue beginning at the 22:05 mark:
Do some research and find out what the other side is, and find out just how dishonest and deceptive that documentary was. There is an argument to be made about whether or not killer whales should be in captivity.
There it is. Right there in front of you. He is saying that the documentary was dishonest and deceptive because it did not present the other side of the captivity argument and that such an argument exists. I suppose the other side of the argument
does exist if the jumping off point is: "Is it neat to see killer whales in person?" But if the jumping off point of the argument is: "There are no detrimental effects to the whales when they are held in captivity", there is simply no "research" or "homework" that supports that. Indeed, you could spend hours on the internet looking for studies that support this hypothesis and the only information that you will find in that camp comes from Sea World itself. So where is the dishonest, deceptive bias now? Every other marine mammal organization refutes what SW has to say on the topic. If one wants to say that SW (which has a financial stake in keeping whales in captivity) is "right" and that every other source of marine biology with no stake in the outcome is "wrong", well then, there is little left to debate. But the truth is, the "
argument to be made about whether or not killer whales should be in captivity" rests solely in the hands of Sea World.
In discussing longevity in captivity, the best argument that SW can muster is "we just don't know", and that the
average life expectancy of killer whales in the wild is approximately 30 years, and that SW has "several" killer whales in their 30's. So Sea World has "several" whales that have made it to the average age. To replicate longevity in the wild, it would have to have its population average out to 30. But don't stop there. Here is a recent paper that one can count as "research" and "homework" that utilizes data pre-Blackfish, and thus has no agenda to either refute or support that documentary.

It is dense reading, but the type of study that one must digest before coming out in favor of keeping whales in captivity. If Pete wants us to do our homework, here it is. The data starts in 1961, when killer whales were first put in captivity in the U.S., and draws from records from the
Marine Mammal Inventory Report, a database run by the National Oceanic and Atmospheric Administration (NOAA) that catalogues all the marine mammals held in the country. It can hardly be said that NOAA is a biased source with a journalistic axe to grind. The conclusion? Things have improved over time. Facilities in the U.S. do better than facilities in the rest of the world. But whales in captivity do not fare as well as those in the wild.
But frankly, all of the discussion of longevity is simply irrelevant to the larger question of "quality of life" for immensely intelligent animals. Where is the "other side of the argument" that killer whales "should" (using Pete's word) be kept in captivity when they are huge creatures that swim many miles a day in pods and hunt in packs. To the extent that a zoo or marine park seeks to justify its content by claiming that it has fairly replicated the animals' natural habitat, such claim simply cannot be made with respect to killer whales. As I mentioned earlier, if one wants to keep a clown fish in a tank where it stays close to its protective anemone, I doubt anyone will care. But the man-made habitat of a killer whale at a marine park is not even close to its natural habitat. Nor is its secluded, solitary life kept penned away from other animals. These are group-living creatures whose pods stay cohesive for decades. Where is the "other side of the argument" that an animal that lives in such conditions in the wild "should be in captivity" where it is isolated from its pod, is not permitted to roam dozens of miles in a day, and cannot hunt with its podmates? I've looked for such research and I simply cannot find it. The other side of the argument seems to be tethered to: "Killer whale shows are really cool and people like them". But an argument based on the overall benefits to the animal in general and the species as a whole? I find that completely lacking.
