Description

The species can grow to be up to 30 cm by the end of the first year, and 400 mm if male and 480 mm if female by the first reproduction. It grows to a maximum length of 1.35 m (4.4 ft).[1]

Distribution and habitat

The white hake is found in the northwest Atlantic from North Carolina to Newfoundland, at depths of about 180–1,000 m (590–3,280 ft).[1]

Reproduction and development

Spawning season for the white hake starts in late winter or early spring. It has been difficult to study the breeding habits of the white hake due to researchers’ issue with finding ripe females. Studies have found that larvae for the species occur in warm Slope Sea waters, but further along in development, the species can be found in continental shelf waters.

gollark: ... that is an internal IP.
gollark: I host my site off a dynamic IP using the magic of dynamic DNS™. The main downsides of that are that there's some downtime when my IP updates, that my dynamic DNS provider is probably less reliable than a non-dynamic one, I can't really do things which require a static IP rather than just a static-ish domain, and I need to have a script run to update DNS which takes some nonzero amount of effort to install.
gollark: I don't think most VPNs will let your stuff listen on external ports. Also, they won't assign you a fixed IP *either*.
gollark: Also <@361606054154469376>, you might have a dynamic IP (probably do if it's a home internet connection), so you'll either need dynamic DNS or will have to give people the new one a lot.
gollark: The worst people can do with your IP is get your approximate location. Which is somewhat bad, but I'm sure people can decide for themselves whether they care much.
