This is a picture of a salmon farm that has been established in Marlborough Sounds for thirty years. The farm has ten 20m x 20m pens, and there are a total of 300,000 fish in the whole farm. The conservation ethic of the owner is of particular relevance and interest. The owner explained that the farm intends to be environmentally conscious by avoiding the use of chemicals, and by experimenting with different fish feed. He is concerned about the impact of using fish meal as a source of feed, so he is experimenting with alternatives such as beef and soy. Whether these alternatives will help to promote environmental conservation is highly debated.
