Fish waste, often viewed as a nuisance or an environmental burden, plays a surprisingly vital role in aquatic ecosystems. This organic material, which includes excretions, uneaten food, and decomposing fish, serves as a rich source of nutrients that supports a myriad of life forms in aquatic environments. From the smallest microorganisms to larger predators, fish waste contributes to the intricate web of life beneath the water’s surface. In many ecosystems, the decomposition of fish waste is facilitated by bacteria and other detritivores, which break down the material into simpler compounds. This process not only recycles nutrients but also enhances water quality, promoting a healthier environment for aquatic organisms. The role…
