🦐 Diet
The diet of the fish is rich in crustaceans such as the isopod Pentidotea resecata, as well as cephalopods and gastropods, and it is known to prey on juvenile blue rockfish (Sebastes mystinus) and plainfin midshipmen (Porichthys notatus). It does most of its hunting at night. In captivity, larvae have been reared on diets of Brachionus plicatilis, a rotifer, with supplements of copepods and veligers as they develop. The nauplius of the brine shrimp Artemia salina becomes the main food later. Captive adults can be maintained on chopped squid and live prey such as the night smelt (Spirinchus starksi).
