The event, which first began in 2012, takes place on the Stade on Hastings seafront and aims to promote the herring, which locals feel is an under-appreciated fish.
A variety of stalls will be set up over the two-day fair, showcasing the range of different culinary practices such as herring cookery, pickling and smoking skills.
A local marquee contractor believes that despite the recent bad weather, any major complications are now behind them.
“We were up against it because it rained all day, but despite the tricky conditions, it’s so far so good and we’re definitely on schedule for making this year a good event.”
As well as the different stalls, the fair will also offer films, talks and exhibitions in the Stade Hall and Fishermen’s Museum revealing the history of herring fishery.
