Avoidance of towed plankton nets by herring larvae: a model of night-day catch ratios based on larval length, net speed and mesh width

Abstract

Thirteen sets of night-day catch ratios for Pacific and Atlantic herring larvae were collected from the literature and used to develop a regression model of the night-day catch ratio. The model explained 75% of the variance in ln(night-day catch ratio) as a function of larval length, the towing speed of the net and mesh width.
