The trend could have noticeable benefits for people's health, as it offers a good alternative to red meats for those trying to slim down for the summer, as well as containing important nutrients.
Recent research by YouGov SixthSense shows that 42 per cent of us now try to serve fish at least once a week, with a further 25 per cent regarding seafood dishes as part of our meal repertoire.
However, the poll suggests that even more of us would be whipping up fish-based dishes if we knew how to prepare them properly.
Researchers found that 24 per cent of consumers would like to cook a wider variety of fish, but are prevented from doing so because they do not know how to prepare it.
Almost one in five (18 per cent) respondents admitted that they tend to serve up prepared fish products and dishes rather than cooking them from scratch, while 15 per cent visit fish and chip shops - not the healthiest of options! - instead of cooking fish at home.
Seafood seems to pose a particular problem, with 13 per cent of people worrying about overcooking or undercooking it and 12 per cent simply finding it too complicated to even attempt to cook at home.
James McCoy, research director at YouGov SixthSense, said: "The fact that a significant minority of consumers would like to serve more fish but lack confidence in its use shows that there is potential for growth in this sector.
"Although seafood is less popular it may simply be that seafood is not on the radar for many people to cook and eat at home."
Health experts say we should aim to eat at least two portions of fish - including one of oily fish - each week.
Fish and shellfish contain many important vitamins and minerals, which oily fish is particularly high in omega-3 fatty acids, which are thought to be good for your heart.
