What habitat do juvenile black rockfish prefer? •Rocks (abiotic) and living structures (biotic) such as sea anemones, provide valuable habitat for young rockfish. •Marion Mann’s research demonstrated that young rockfish prefer these environments. •Without places to hide, young rockfish are more susceptible to predation.

What habitat do juvenile black rockfish prefer? • Abiotic structure (boulders) and biotic structures (animals like anemones), can provide valuable habitat for young rockfish. • Marion Mann’s research demonstrated that juvenile black rockfish not only prefer structure but also biotic components (other animals) within their habitat. Some marine animals (biotic invertebrates) live to reach ages as high as 300 -1800 yrs. • Without places to hide, young rockfish are more susceptible to predation.
