i looked into this Dr Andrew Trites fellow and there are a number of other (shorter) interviews with him where he lays out the same findings.
essentially, what they know to date is that the norther resident orcas are doing very well and expanding. the transients are doing great and expanding (and now basically live in the inner waters due to pinniped abundance) and the southern residents are likely on their way out. they live between northern California and here and are not finding enough spring salmon across their range and are not adapting to other fish. sad.
It makes sense. The Spring Salmon of the past on the south coast were legendary 100 years ago. Where I grew up (Pender Harbour on the SSC) there are old-timey pictures of guys pulling in multiple 80 to 100 lb fish in a day. Those would be decent dinners for an Orca.
