Tilt angles of schooling penned saithe
Original version
This report is not to be cited without prior reference to the authorsAbstract
Saithe (Pollachius virens) of nearly uniform 32 cm length have been
photographically observed during the daytime in an apparently
free-swimming and schooling state in a pen of dimensions 90 m length,
10 m width, and 7 m depth. The resulting tilt angle distribution is
essentially normal, with mean -0.9 deg and standard deviation 5.4 deg.
