Rockfish normally live in a variety of habitats. Some live on rocky reefs or seafloors in near shore shallow waters. Others live on the deep seafloor or in the water column. In giant kelp forests, rockfish hover motionless under the kelp canopy, maintained by their air bladders. Some species rest on rocks at the bottom of the kelp forest, with creatures like sea cucumbers and abalone. Rockfish, also known as rock cod or Pacific red snapper, are popular with seafood lovers. But some rockfishes don’t breed until they’re 20 years old, and they have few young—these factors make them very vulnerable to overfishing.
Rockfish have large mouths that allow them to quickly inhale their prey. Most rockfish are territorial and will diligently defend their territory against perceived threats. Rockfish generally fall into two categories: red-fleshed and brown-fleshed. Red-fleshed fillets are generally considered more desirable, because they are less oily and have a longer shelf life. Rockfish fillets have a firm texture that holds up in soups and stews. They work well baked, steamed, fried and sauteed, but they’re not sturdy enough to grill.
Rockfish come in more than 100 species and many different shapes, sizes and color patterns. Colors vary from black and drab green to bright orange and red, and some rockfishes wear stripes or splotches. Their heads feature large eyes and thick, broad mouths that dip downward at the corners. Rockfishes are known for the bony plates on their heads and bodies and the heavy spines on their fins.
