17. Three measures or laws which help countries maintain or conserve populations of endangered fish at healthy, constant levels include.........
a) Banning use of drift nets which catch all species, not just the desired fish species.
b) Use nets with minimum net sizes, so juvenile fish can escape and grow up to reproduce.
c) Place and enforce quotas on how many fish of a species may be caught.
d) Monitor the numbers of fish of each species that are of reproductive age (count the rings of the scales).
e) Ban the catching of endangered species (or for sports fishing, promote catch and release).
