ESTIMATION OF INDICATORS OF PROBABILITY OF RETENTION AND DIRECTION OF FISHES WITH THE TRAP WING
Journal Title: Вестник Астраханского государственного технического университета. Серия: Рыбное хозяйство - Year 2012, Vol 0, Issue 1
Abstract
The main indicators of fish behavior during retention and direction of fish with the trap wing are considered. The experimental data supporting M. Gurevich’s hypothesis on the oblique crowding of fish on the net wall are given. The parameters of the vortex fields of net elements of the wing are as-sessed. In some cases, some characteristics and a number of dependencies, describing the mathematical model of the direction of fish using the wing into the trap, are completed and optimized.
