Unfortunately the fact that there are indeed millions of fish does not mean that it is okay for people to kill and take trailer loads of fish, which they are doing...
This is completely the wrong attitude to take, as usual in life these days nothing will be done until it is too late. Acting now ensures education and management of a resource enjoyed by many people, including those that killl for the table, but it has to be governed and the attitude that there are millions of fish anyway will not be something that is true in the future unless measures are put in place...
The human race is the same in everything, do nothing until it is too late...
