Chinese seafood and snacks firm China Marine Food Group has said CFO Marco Ku is to step down from the company.

The group, listed in the US, said Ku “resigned ambicably and has no disagreements with the company on any financial or business issues”. He will leave the role on 30 October.

“Marco has been an architect in the success of our capital raises over the past six years and he was also instrumental in our uplisting to [the] NYSE MKT in 2009. We will provide an update on the replacement CFO as soon as information is available,” chairman and CEO Pengfei Liu said.

Last month, China Marine reported lower half-year losses despite a fall in sales. Lower operating costs helped China Marine’s bottom line. Marine catch revenues fell amid lower selling prices, which led the company to hold back stock for higher prices in the third and fourth quarters.
