Shelltas Reared Scallops Seven Months in Artificial Seawater
The company is pitching closed land-based shellfish production as an answer to warming seas, and the Akihabara scale-up is where that claim either holds or does not.

Shelltas Co., Ltd., based in Tokyo, kept scallops growing for about seven months in a closed land-based tank using artificial seawater made from naturally derived ingredients and no natural seawater, with no water exchange. The company says it also reared scallops and abalone together in the same tank, and that its next step is a scale-up demonstration in Akihabara, Tokyo.
The trial ran at the company's own lab with no natural seawater. Instead it used artificial seawater developed from naturally derived ingredients, at a water temperature of 13-15°C, salinity of roughly 33 permil, and pH of about 8.1 to 8.4, with no ultraviolet or ozone sterilization and no water exchange over the roughly seven month period.
Shelltas says it also reared scallops and abalone together in the same fully closed tank, and plans to test combinations with fish, seaweed and microalgae. The scale-up demonstration in Akihabara is the company's stated next step.
