One of the oldest fish purveyors in New York, M. Slavin & Sons, filed for Chapter 11 bankruptcy protection on Monday.

Founded in the early 1900s, the family-run business, which is based in the Bronx, also operates a processing facility in Point Judith, R.I. It delivers seafood, including whole fish, fillets, live shellfish and breaded, smoked, canned or frozen products, to more than 1,000 customers in the tri-state area.

According the filing, the company lost a lot of business in 2009 and 2010. It cut payroll by almost 50% during that time to lower its expenses and also shut down unprofitable lines of business. There are currently 105 employees.

Its liabilities include a $5.4 million debt to Capital One and an $11 million debt to the Hunts Point Cooperative Market.

The company says it is close to reaching a deal with a finance company for an $800,000 loan to be used as working capital, allowing it to continue purchasing inventory and making deliveries.
