Bluenose warehou
📖 Overview
Most common over or near rocky areas at 100-300 m . Generally, blue eye remain close to the sea bed during the day and move up in the water column at night, following concentrations of food . The fish are found over rough ground and at the edges of canyons and steep drop-offs. Blue eye appear to prefer cold water as part of their general behavior . Juveniles inhabit surface waters, sometimes in association with floating debris . Feed primarily on the pelagic tunicate Pyrosoma atlantica which is found near the sea bed during the day but dispersed throughout the water column at night . They also feed on squid, mollusks and crustaceans and fish ranging from small lanternfish (Myctophidae) to large fish such as gemfish (Rexea solandri). Juveniles consume small planktonic and sedentary organisms . Marketed fresh and frozen; exported to Japan for sashimi; eaten steamed, fried, broiled and baked .

🥚 Reproduction
In Australia, spawning appears to be correlated with water temperature and nutrient upwellings . It appears that mature fish move up the continental slope into shallow depths (320-400 m) and aggregate in specific grounds for spawning . There is no information on the number of eggs blue eye produce nor on the egg and larval stages of their life history .
