Deep dive of the week: Automatic feeders

Inspired by this week's article on automated feeding from our colleagues at Auburn University, let's look at one of the top aquaculture innovations of the past decade, which is saving operators time and money and making aquaculture more efficient and less wasteful. Solutions employ various types of sensors to evaluate fish behavior, and consequently hunger level, to dial in the right amount of feeds and to turn the feeders off when the fish are sated. Here are a number of articles that dig into the technology and how fish and shrimp production have benefitted. (Photo courtesy of eFishery).

AQUACULTURE IS ...

... where collaboration happens

A “friends and family” approach is paying off in efforts to recruit fish farmers into environmental-protection initiatives known as aquaculture improvement projects (AIPs), according to a story by Lisa Duchene published in January 2020. A Wageningen University-led study of how to reduce risks and improve environmental performance among small aquaculture operations also aimed to reduce the incidence of disease, via four new AIPs at shrimp farms in Indonesia and in the Thai provinces of Surat Thani and Chumphon.
