Although the movie is dubbed "The Turkish Jaws" on some movie websites (probably because it sells more bootlegs), it's not really a remake of Jaws. There is a shark in this movie, but it appears only for a couple of minutes toward the end of the film, and it's completely unrelated to the plot. It doesn't even kill anyone.
The name of the movie (Cöl) means "desert". The actual title was going to be "The Blue Desert", implying that the sea, in its vastness, is like a desert for a man left alone in the middle of it (the lead character's fate). However, the printhouse owner thought it must be a mistake, "because the desert cannot be blue", and called the filmmakers. When he couldn't reach anyone, he used his initiative and printed all the posters with the title shortened to Cöl. When the filmmakers finally found out, rather than spending money on new posters, they decided to go along with it and released "The Blue Desert" under the title "The Desert."
