An assessment of juvenile Atlantic cod Gadus morhua distribution and growth using diver operated stereo‐video surveys
Stereo‐video scuba transects were conducted during daylight hours from June to September 2013 within a proposed marine protected area (MPA) in the Firth of Clyde, west of Scotland. More juvenile Atlantic cod Gadus morhua of fork length (L F) range 6–11 cm were observed in substrata containing mixed...
