ADCPs contribute to improving Chile’s aquaculture industry
Between the early 1990s and 2007 Chile’s aquaculture really took off, and by 2006 the country was producing 38 percent of the world’s salmon. Nowadays, the country produces 1.4m-1.5m tons of salmon a year, putting it on a par with the world’s biggest producer, Norway. But there is still significant potential for Chile to run its aquaculture operations more efficiently and profitably. A study by Mariscope Ingenieria SPA found that using Doppler technology and real-time data could reduce food loss by up to 20%.
Measuring waves and currents helps with issues such as calculating the most effective location of the cages’ moorings, the shape of those cages, and the position of floating barges. It also helps fish farmers economize on fish fodder. Typically, fishmeal is unnecessarily wasted during the feeding process, as currents draw the pellets through the cages’ netting. As an example, constant measuring giving real-time data can be supplied via Nortek’s Aquadopp current profiler and the Autonomous Online System (AOS), in addition to other sensors (for oxygen, salinity and temperature).
