If you were to judge the health of land-based salmon farming by the performance of Atlantic Sapphire, the world's largest producer of land-based salmon, you might conclude the sector is struggling.

Atlantic Sapphire has experienced a string of mishaps and setbacks since it began operations in Miami and has yet to produce the level of fish it promised.

Making matters worse, the fish it has produced has received mixed reviews in the marketplace, with a number of US retailers expressing dissatisfaction with the fish's performance.
