Some people feel that fish farming, particularly for salmon, create environmental problems. In British Columbia, a court has recently ruled that the government must release information about sea lice and other data gathered on fish farming. You can read about it here.
This is a good thing for so many reasons. Information gathered by government authorities about practices that impact the population at large should be made public. Since we have so many regulations and administrative bodies governing many areas of our society the more open the better. If we are all aware of what is going on and complete information is available to everyone better decisions can be made.
