Ontogeny , diet shifts , and nutrient stoichiometry in fish

  title={Ontogeny , diet shifts , and nutrient stoichiometry in fish},
  author={Alberto Pilati and Michael J. Vanni},
Most stoichiometric models do not consider the importance of ontogenetic changes in body nutrient composition and excretion rates. We quantified ontogenetic variation in stoichiometry and diet in gizzard shad, Dorosoma cepedianum , an omnivorous fish with a pronounced ontogenetic diet shift; and zebrafish, Danio rerio, grown in the lab with a constant diet. In both species, body stoichiometry varied considerably along the life cycle. Larval gizzard shad and zebrafish had higher molar C:P and N… CONTINUE READING
