• Contamination:  Farmed fish usually contain more contaminants. Farmed fish are fed processed pellets, often made from processed anchovies, sardines and other small fish. Unfortunately, the types of fish used to make the pellets are usually caught in the polluted waters closer to shore and are often contaminated with industrial chemicals. As a result, farmed fish tends to have much higher levels of chemical contaminants that may cause cancer, memory problems, and neurobehavioral changes in children. Farmed salmon, for example, has been found to contain seven times more PCBs (polychlorinated biphenyls), dioxins and pesticides than wild salmon. Consumers can reduce the amount of contaminants in farmed salmon by almost half by grilling or broiling it so that the juices drip off, cooking it until the internal temperature reaches 175 degrees Fahrenheit and removing the skin before eating.
• Antibiotics:  Besides being prone to industrial contamination, farmed fish are more subject to disease, which spreads quickly throughout the entire pen. Sick fish can escape into surrounding open water and spread disease to wild fish populations. To control disease, farmed fish are often given antibiotics to prevent the whole group from becoming ill. Research has shown that farmed salmon, for example, are administered more antibiotics by weight than any other type of livestock.
• Lower Omega-3' s: While farmed fish  can  be fed an enhanced diet to increase its Omega-3' s, there is no way for consumers to know whether one piece of fish contains more healthy fats than another.  According to  research in  The American Journal of Clinical Nutrition,  farmed salmon contains two or three times  fewer Omega-3' s even though it contains more  overall fat than wild salmon due to its grain-based diet.  The same is is true for other popular farmed fish, such as catfish and tilapia.

• Flavor:  Many people prefer the taste of wild fish. Farmed fish do not have as much room to move as their wild counterparts, which reduces the amount of muscle they can develop and affects  texture and taste.
• Appearance:  Wild salmon is naturally bright in color due to its food source (krill and other small sea creatures), while farmed salmon is grayish in color and dyes must be added to bring the flesh to an appealing shade.
• Nutrition:  Wild fish are usually healthier (higher in Omega-3s) and less contaminated than farmed fish.

A new report from the UN reveals that aquaculture or farmed fish consumption is at record high.   This will help sea catches to become sustainable as rise in aquaculture fish will reduce over-fishing in the sea.      Human consumption of fish has increased but nearly half of those consumed is no longer caught wild but is grown in farms, says the United Nations.  Around 80m tonnes of fish were caught " wild" in 2011-12 while 90 million tonnes came from aquaculture.    In 2012 alone,  the aquatic fish increase was about 10% or 10m tonnes.     

Therefore,  aquaculture or farmed fish is where the future growth would be.  I would invest in CF when that day comes.
