A little about Trevalla

Benthic species like the blue-eyed trevally are found in the depths of continental slopes on rocky sea beds, and the typical depth range for juveniles is from midwater to the surface. There are several common names for this species, like the Big Eye, Big-eye Trevalla, Blue-eye, Blue-eye Cod, Blue-nose, Blue-nose Warehou, Bonita, Bream Trevalla, Deep-sea Trevalla, Griffin’s Silverfish, Sea Trevally, Stoney-eye Trevally, Antarctic butterfish, deep sea trevally, blue eye fish, bluenose sea bass, or deep sea trevalla are some of these.

Many think the blue-eye trevalla, fished in Australia’s southern waters, is among the best table fish. This fish’s firm, juicy, and delicately flavored white flesh makes it very adaptable and well-liked. The blue-eye trevalla is a large, thick-bodied finfish readily available throughout the year and has developed a significant following over the past twenty years. Also excellent for eating, its flesh has a moderate flavor, and most cooking methods work well with this firm-fleshed fish. Fillets taste best when grilled or fried; when sliced into cubes and individually coated with herbed crumbs or batter mixture, they form a delightful delicacy for finger food. Deep-frying should only be done with thin chunks to achieve even cooking.

Traits of blue-eyed fish

Blue-eye cod is another name for blue-eye fish. Because of its firm, juicy, and delicately flavored white meat, it’s very adaptable and to the liking of most people, and they mostly prefer grilled or fried fillets.

The belly is grey and fades to a blue-gray color on the body, further, the fins are a shiny dark gray.

The blue-eye trevalla is a benthic species that prefer rocky terrain on continental slopes. Typically, H. Antarctica exists 200 to 900 meters below the surface. S. labyrinthica typically exists at depths of 40 to 500 meters and is more closely related to ocean seamounts. H. Antarctica juveniles usually breathe in surface waters, sometimes near floating trash because H. Antarctica typically spends the day near the sea floor and the night higher in the water column.

Reproduction and life span

Male and female blue-eye trevallies mature for reproduction at 8 to 9 years old and 11 to 12 years old, respectively. In the summer and fall, spawning takes place. Moreover, adult fish move into shallower waters and congregate in particular areas to lay eggs. Spawning activity is takes place in the waters from central New South Wales to northeastern Tasmania, and in each spawning season, females lay 2–11 million eggs. Blue-eye fish and ocean blue-eye also share similar reproductive biology. When it comes to the age of this particular fish, it is known that it can live for close to 76 years.
