Analysis of poorly adapted salmon post-transfer to the ocean

A leading cause for Atlantic salmon mortality is the transfer of fish from freshwater to saltwater. Once in the ocean environment, fish unable to adjust their osmosis capacity may not be able to feed and will die.

Internally, poorly adapted fish can be identified by the absence of feed in the digestive system, significant decrease in body fat, white or yellow intestine color, and atrophied organs in the abdominal cavity.
