In the wild,salmon,tuna or other active migrating fish get a lot of exercise.When these fish are raised in captivity,without predators or the need to fight their way upstream against the current.they turn into fish couch-potatoes.And not unlike sedentary humans,lethargic fish are more prone to getting sick.As many as 20 percent of farmed salmon dying captivity,apparently because their simply out of shape. A new technical book called Swimming physiology of fish presents scientific research on how various train routines,water turbulence,diet and even the use of robotic fish as swim trainers can keep active fish conditioned.This "fishical" fitness research has shown that when captive salmon exercise regularly they grow bigger have stronger hearts and immune system and are healthier than their sedentary brethren. For an example,a Norwegian study found that when salmon had to swim against an artificial current they were much less likely to a common fish virus than their buddies and still water.The bottom line?Healthier profits for fish farmers and healthier fish on your dinner table.
