Page 2 of 48 26 Abstract 27 Growth and survival of Maurolicus muelleri larvae in Herdlefjorden, Norway were 28 investigated by daily otolith increment analysis. While high egg densities were generally 29 observed throughout the spawning season, three cohorts each with a narrow window of 30 hatching dates were identified. The first of these cohorts was characterized by low growth and 31 poor morphometric condition and disappeared from the fjord during autumn.
