Table 2 Model summaries for the western Norway spawning grounds overall depth distribution during the spawning (sp) and feeding (fp) periods. The response variable was depth for all models. The default treatment contrast in R was used, with the intercept value epresenting females during the day. Square brackets indicate categorical variables, i.e. males and night, tested against this reference value.Fixed effects; length = length centered – continous variable, sex = sex of fish – categorical variable, DN = day or night – categorical variable. X indicates interaction. The values for the fixed effects are shown at the top of the table with the random effects underneath.
