Effects of tank wall pattern on survival, bone injury rate, and stress response of juvenile Pacific bluefin tuna, Thunnus orientalis.

Highlights: [•] The juvenile PBT suffers high mortality through contact or collision with tank walls. [•] Fish mortality, bone injuries, and stress responses decrease in patterned wall tanks. [•] Survival rates of fish in lattice and polka-dot pattern walled tanks did not differ. [•] Mass death in juvenile PBT is failure to see the tank wall. [ABSTRACT FROM AUTHOR]
