Length-weight and otolith size to standard length relationships in 12 species of Southern Ocean Myctophidae: a tool for predator diet studies
Fish morphometric relationships are key tools for fisheries science and studies of food web dynamics and predator foraging behaviour, but parameterisations are limited for Southern Ocean myctophids (Family Myctophidae). New standard length (LS) to total mass (MT) relationships are therefore describe...

New linear regressions for otolith size (length; OL and width; OW) and LS are also described.
