McCrindle explained she had painted directly onto the fish then paper was placed over the top to create an impression or print, before drawing fine lines to add detail to the different sea life.
The council said the designs were printed onto recycled fabric by local company, Sailflags.
McCrindle said: “The work has naturally evolved into something much broader than simply fish printing.
“Everything I create is deeply connected back to Newlyn, its fishing heritage and the concept of ‘continuing the journey’.
“The fish used for printing are eaten afterwards rather than wasted, with bones, skins and even ash continuing into other creative processes.”
