About Improver Programme

The MarinTrust Improver Programme (IP) was developed by the MarinTrust Governance Board, with the aim of encouraging factories not yet meeting the criteria for the Standard, due for example, to a lack of fisheries management or factory infrastructure and operational issues, to implement timely improvements, fulfil the criteria, and gain certification to the Standard.

Once accepted onto the Improver Programme, applicants have a structured improvement journey mapped out with agreed milestones and a timeframe that must be met in order to  become MarinTrust certified.


The MarinTrust and its Governance Board became aware that despite the initial success of their Standard, a lot of marine ingredient producers failed to meet the criteria. Reasons for this included operational issues within a factory, or with raw materials and their associated fisheries. Many of these producers are based in Asia, which is rapidly increasing aquaculture potential. This means that local companies wishing to use MarinTrust certified ingredients have to import at a higher cost, contributing to local poverty.

Main Objective

The solution was to develop a credible and robust structured programme of improvements for producers, in line with the MarinTrust Standard, to allow approved Improver Programme factories to reach the standard within a defined timeframe.
