Note: U c 1 is the critical velocity when SI increases to 1; U c 2 is the critical velocity when SI begins to reduce from 1;
U c 3 is the critical velocity when SI reduces to zero. The velocities between U c 1 and U c 2 is the best for the species. The
species prefer live in waters with no velocities larger than U c 3 .
