This book is a unique cross fertilization of aquatic ecology and aquaculture. It shows how
diets structure the digestive tract and its microbiota and in turn the microbiota influences
life history traits of its host including behavior. Short-term starvation can have beneficial
effects on individuals themselves and succeeding generations which may acquire multiple stress
resistances - a mechanism strengthening the persistence of populations. From terrestrial but
not yet from aquatic animals it is understood that circadian the rhythmicity makes toxins or
good food. On the long-term the dietary basis impacts succeeding generations and can trigger a
sympatric speciation by (epi)-genetics. This volume defines gaps in nutritional research and
practice of farmed fishes and invertebrates by referring to knowledge from marine and
freshwater biology. It also points out that dietary benefits and deficiencies have effects on
several succeeding generations indicating that well designed diets may have the potential to
successfully improve broodstock and breeding effort.
