One fisherman in Buenaventura, Columbia caught a fifty centimeter long brown and grey fish he could not identify. later he was told it was a Cobia and it should not be in there. The fish is said to have escaped from fish farms in Ecuador. The farmer of these fish claims intruders came into the farm and cut the net releasing around 1,500 fish into the ocean. Though not native to the Eastern Pacific ocean they have been found from Panama to Peru. By a study of six European countries, over three years, nine million fish have escaped these off shore pens. Some escapees such as Tilapia have overthrown the native fish when they escaped there nets. When a majority of fish escape these off shore or shoreline nets they tend to take over the native fish and weaken the whole environmental structure of the sea they are in.
