A 2021 study by Zhang et al. emphasized that salinity affects various biological processes, such as respiratory efficiency and metabolic rate.
Osmoregulation: Osmoregulation refers to how fish maintain their internal fluid balance in response to external salt concentrations. Marine fish drink seawater to help cope with high salt levels. They excrete excess salt through specialized cells in their gills and produce small amounts of urine. Conversely, freshwater fish absorb water through their skin and gills due to lower external salt levels and excrete large quantities of dilute urine. The journal Fish Physiology and Biochemistry noted this difference significantly impacts fish health and behavior (Brett et al., 2018).
Disease Susceptibility: Marine fish are often exposed to different pathogens than freshwater fish. They are prone to specific diseases such as marine ich and mycobacteriosis, while freshwater fish may encounter diseases like ichthyophthiriasis and columnaris. According to the American Journal of Fish Diseases, the varying levels of stress in each environment can also influence disease resistance.
Nutritional Requirements: Marine fish generally require higher levels of certain nutrients, such as omega-3 fatty acids, due to their natural diet in saltwater. They may need specialized diets that reflect their natural prey. Freshwater fish often have different protein and fat requirements. Research by the Aquaculture Nutrition journal suggests that understanding these differences is crucial for optimizing fish health and growth.
Environmental Conditions: Marine fish usually inhabit more stable thermal and pH conditions compared to freshwater fish, which may experience greater fluctuations. Temperature changes can significantly affect metabolism and immune response. A study by the Fisheries Ecology Research Group indicates that fluctuations in environmental conditions can lead to stress and health issues in fish.

In summary, marine and freshwater fish have varied health needs due to differences in their environments. Recognizing these distinctions helps in providing appropriate care, ensuring their health and longevity.
