But retailers can help to create markets. I know that import costs and MAF fees etc are very expensive for importers here, but it strikes me that the biggest mark up is between the importer and the retailer (and when the retailer is ALSO the importer, there is even less of an excuse for this). If certain fish were available at lower cost there would be higher demand because more people could afford the fish they desire.
If the price is right there will be greater demand on the retailer by the consumer; in turn the retailer will be asking the importer to bring in higher numbers and the cost of import will benefit from economies of scale and be cheaper - importers should then be more willing to import and the availability and diversity of fish should improve, along with lower prices .....
(in an ideal world, lol)
