As sequel
to Aquatic Animal Nutrition – A
Mechanistic Perspective from Individuals
to Generations, the present treatise
on organic macro- and
micronutrients continues the unique
cross fertilization of aquatic
ecology/ecophysiology and aquaculture.
This treatise considers proteins and their
constituents, carbohydrates from mono- to
polysaccharides, fatty acids from free
acids to fat, and waxes. It becomes
obvious that these organic nutrients are
more than only simple fuel for the
metabolism of animals; rather, their
constituents have messenger and
controlling function for the actual
consuming individual and even for
succeeding generations. This aspect will
become particularly clear by putting the
organisms under consideration back into
their ecosystem with their
interrelationships and interdependencies.
Furthermore, micronutrients, such as
vitamins and nucleotides as well as
exogenous enzymes, are in the focus of
this volume with known and
still-to-be-discovered controlling
physiological and biomolecular functions.
Aquatic Animal Nutrition – Organic
Macro and Micro Nutrients addresses
several gaps in nutritional research and
practice. One major gap is the lack of
common research standards and protocols
for nutritional studies so that virtually
incomparable approaches have to be
compared. This applies also to the studied
animals, since most approaches disregard
intraspecific variabilities and the
existence of epimutations in farmed
individuals. Furthermore, recalling
the Mechanistic Perspective from
Individuals to Generations, dietary
benefits and deficiencies have effects on
succeeding generations. In most studies,
this long-term and sustainable aspect is
overruled by pure short-term production
aspects.
By comparing nutritional behavior and
success of fishes and
invertebrates, Aquatic Animal
Nutrition points out different
metabolic pathways in these animal groups
and discusses how, for instance, fishes
would benefit when having some successful
metabolic pathway of invertebrates.
Application of novel genetic techniques
will help turn this vision into reality.
However, a widely missing link in the
current nutritional research is
epigenetics regarding transgenerational
heritages of acquired morphological and
physiological properties. To increase
public acceptance, nutritional
optimization of farmed animals based on
this mechanism, rather than genetical
engineering, appears promising.
