A fish tale.
USDA researchers have developed a test to see if the presence of a certain protein, myosin, correlates with a trout's muscle growth. Muscle is what gives the fish its most tender, delicate flavor.
The test results will give trout breeders a new way to pinpoint fish that have the genetic makeup to convert feed into muscle.
Part of the study includes experimenting with grain-based feed, such as oats or barley to see if the fish convert feed into muscle.
The desire for faster-growing fish is intended to meet the future demand for farm-raised fish. Projections indicate U.S. aquaculture production will have to increase by 500% over the next 25 years to satisfy consumer demand.
