I used to work for wallcan cannery on Qudra Island just across from Campbell river BC. I worked through the summer and chose to work with farm fish because the work was more steady. We called the farm fish slimies we often had a fair amount of loss because some of the fish had open sores, mite infestation, absesses and some well, thay were just deformed. Im sure most of the fish were ok but the sick ones realy stood out, and to think thay spent there whole lives swimming in circles with the healthy ones made me decied to stick to wild fish. Ive never come across extreamly sick fish in the wild and if i ever do id be the first one concernd and on the phone with enviroment Canada.
