Aquaculture health, nutrition and genetics company Benchmark has lost two key execs: Chief Scientific Office Alex Raeber and Philippe Leger, a veteran of the aquaculture nutrition industry and temporary leader of the executive management team after CEO Malcolm Pye stepped down in 2019.

Raeber joined Benchmark in 2018 and has since lead the review and streamlining of the company's product pipeline, the integration of Benchmark's innovation teams and the reorganization of the group's inhouse trial facilities.
