Table 3 Model summaries for the mid Norway spawning grounds during the spawning period. The response variable was depth for all models. The treatment contrast of R was used with the intercept value representing 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.
