He's not completely wrong. Marine Bio departments in universities will have a larger percentage of girls in the classes than other STEM fields from what I've seen as well. What he's ignoring though is that this is one of those fields where there are actually pretty few new jobs each year. He's extrapolating what happens in universities that are happy to take your cash for useless degrees and extrapolating that it affects who does the actual science which is where the argument falls apart.
