What does calambre mean as written by ernest Hemingway inthe old man and the sea?

Ernest Hemingway uses the Word "calambre" on page sixty-two of his novel The Old Man and the Sea. So what does calambre mean? Calambre is the Spanish Word for cramp. It would make complete sense for Hemingway to use this Word since Santiago moved from Spain to Cuba, making him a Spaniard.
