- Many modern fish farms already use video cameras to monitor the salmon in their cages, says Aquabyte founder and chief executive Bryton Shang.
- Using audio data from the caged salmon is more accurate and could save Norwegian fish farms 1bn krone a year in un-gobbled feed, believes Mr Sovegjarto.
- He has monitored salmon feeding patterns and other data, such as water temperature and oxygen levels, and this is giving scientists and farmers new insights into the factors influencing how much the fish want to eat.
- Well, according to Lingalaks fish farms in Norway, which produce nearly three million salmon each year, the fish make less noise once the feeding frenzy is over.
- Fish farming is big business – the industry now produces about 100 million tonnes a year – and with salmon prices soaring, producers are turning to lasers, automation and artificial intelligence to boost production and cut costs.
- Fish farms are worth nearly 50bn krone (£4.6bn; $6.4bn) to the Norwegian economy, and this year the country is expected to see growth of 9% in farmed salmon production.
- London-based Hemang Rishi, co-founder of Observe Technologies, says his firm is developing technology that can visually monitor feeding in salmon cages.
