00:00:06.127 --> 00:00:07.250
This one is a roughy.

00:00:08.327 --> 00:00:09.500
It's in the genus Hoplostethus.

00:00:09.700 --> 00:00:13.420
Two different species of possibility out here.

00:00:14.781 --> 00:00:18.710
Looks like kind of armor, armored plates on the front of this fish head.

00:00:20.019 --> 00:00:23.900
And that's exactly why they're called "roughy," because of that rough texture on the head.

00:00:24.809 --> 00:00:28.390
Before people started marketing them, they were actually called slimeheads

00:00:28.590 --> 00:00:31.170
because they produce a lot of mucus on the pores on the head.

00:00:31.370 --> 00:00:35.820
That wasn't such a great name for marketing purposes, so they started calling them roughies.

00:00:36.812 --> 00:00:40.180
The roughies have been aged at 80 to 100 years old.

00:00:41.214 --> 00:00:45.150
So very long-lived fish and they mature at about 20 years or so.

00:00:45.350 --> 00:00:48.930
That's one of the reasons why they're so vulnerable to overfishing --

00:00:49.130 --> 00:00:51.300
they're slow growing, slow reproducing.
