Delaware-based CleanFish has filed a lawsuit against its former co-founder Dale Sims for launching Buena Vista Seafood, a new company CleanFish accuses Sims of stealing "confidential data" as well as customers to create.

Lawyers for CleanFish argued in a filing with a US district court in Northern California on June 24 that Sims and Nanci Dixon of Island Sea Farms, a former mussel supplier to CleanFish, used "detailed customer lists, purchasing data, sales figures and other analysis" to directly compete with CleanFish and divert business away from the company.
