Humic Substances color all waters more or less brown. Their concentrations exceed all carbon of living organisms by at least one order of magnitude. Opposite to former paradigms, they participate in almost any metabolic pathway. They protect against UV-irradation, enable indirect photolysis and, thus, purify hazardous chemicals, they provide inorganic and organic nutrients, may form cryptic genes with DNA and dampen metabolic fluctuations. More recently they can increase adverse effects of hazardous chemicals and they can directly interfere with organisms. The book tries to relate effects to structural features.

Exploring the interplay between aquatic ecology and aquaculture, this book delves into how diets shape the digestive systems and microbiota of aquatic organisms, affecting their behavior and life history traits. It highlights the potential benefits of short-term starvation, which can enhance stress resistance in individuals and future generations. Additionally, the work discusses the influence of dietary patterns on long-term population dynamics and the possibility of sympatric speciation through genetic and epigenetic mechanisms.
