This system, which combines optical and acoustic technologies, will be environmentally friendly and will provide reliable information about the condition of marine fish stocks, something that at the moment is practically impossible to achieve without investing enormous resources.
The system is the product of an international scientific initiative under the EU's Horizon 2020 program.
"The system will be environmentally friendly, not only in its operation which will be non-invasive and won't impact the marine ecosystem, but more importantly because it will provide reliable information about the condition of marine fish stocks.
At present, it's virtually impossible to collect such information without investing enormous resources.
The development of fishing technology since the twentieth century has resulted in the growing realization that fishing is one of the most serious problems facing marine ecosystems.
Global fishing authorities are hoping to curb over-fishing with new regulations and enforcement based on fish stocks.
