The immune system of a poikilothermic vertebrate like fish is affected by seasonal temperature changes. In many fishes, reduced immunity is often recorded during cold periods due to the low temperature. The immune system of the teleost fish contains various mechanisms of non-specific (innate or natural) immunity and specific (acquired or adaptive) immunity that determine resistance against pathogenic or parasitic organisms. The measurements of nonspecific immune parameters are useful as markers of pollution to determine the health status of fishes and also many cells (in particular leucocytes and macrophages) and their products [myeloperoxidase (MPO), superoxides, lysozyme, complement, acute phase proteins, interferons, agglutinins, properdins and lysins] contribute to the general immunological defence mechanism.
