There was a short time period at the start of this catering truck craze when individuals wondered whether or not food trailers serving fish products would do well. Now, though, we see these trucks popping up all over the nation – and there's little doubt in our minds that this was a successful maneuver on the part of the food truck industry.

Food trucks like The Lobsta Truck, Feelin' Crabby, Rockin' Roll Sushi are prime examples of mobile food vendors who sell seafood – and get away with remarkably higher-priced items compared with other food trailers. What's the point? These trucks are serving quality seafood dishes, and everyone's catching on. So how can you differentiate yourself from the competition if you're looking to serve fish from your mobile food stand?

The best way to go is to serve sustainable seafood. This type of seafood refers to seafood that is farmed or fished from sources that can maintain or increase productivity without damaging the ecosystem and threatening the availability of future seafood supplies.

And if your customers are seafood lovers, they'll know and appreciate the sustainability movement on behalf of your truck. You can also educate customers who don't know the benefits of using sustainable seafood so that they are aware of the environmental efforts your catering truck is taking on.
