As most of us have been hunkering down over the last few months, we’ve been shopping for more of our own food and eating out less. As you’ve perused the seafood section of the grocery store, you may have wondered to yourself what type of fish is OK to buy. This week on Sea Change Radio, we look at seafood supply chains with Espen Braathe who heads up IBM Food Trust Europe. He works with the company’s clients in the aquaculture industry to help them implement blockchain technology to track the quality of sustainably farmed or fished seafood. Then, we dive into the archives to speak with Bay Area educator and entrepreneur Kirk Lombard to learn more about his sustainable seafood delivery service, Sea Forager.
