The word "fish" in literature is employed in a variety of ways that extend beyond its literal sense, often serving as a rich metaphorical or symbolic element. Authors use fish to evoke natural abundance or scarcity—Thoreau observes that his pond is not very fertile in fish ([1]), while Chekhov and Kipling employ the act of catching fish to suggest a pursuit of opportunity or understanding ([2], [3]). In mythological and religious texts, fish take on spiritual significance, as seen in Homer’s portrayal of ancient fishing practices ([4]) and their ritualistic inclusion in biblical narratives ([5]). Meanwhile, in works such as Melville’s Moby Dick and Kipling’s Just So Stories, fish serve as playful symbols for human traits or social commentary ([6], [7]); and in scientific and observational writings, fish become a subject of detailed study, marking the boundary between art and nature ([8], [9]). This multifaceted usage illustrates how fish transcend their physical existence to represent deeper cultural, philosophical, and natural themes in literature.
