Effect of food deprivation on distribution of larval and early juvenile cod in experimental vertical temperature and light gradients by Vollset, K. W., Catalán, I. A., Fiksen, Ø., Folkvord, A.

“…How and when food limits the growth and survival of larval fish are essential questions which link oceanography and fisheries science, and theory suggests that…”
