Free amino acid and protein contents of start-feeding larvae of turbot (Scophthalmus maximus) at three temperatures
10 páginas, 5 figuras, 3 tablas The contents of free amino acids (FAA) and total protein, together with growth and gut-content, of turbot (Scophthalmus maximus L.) larvae reared at 14, 18 and 22 °C were studied from first-feeding to approximately 140 effective day-degrees post hatch (Deff ∘). Artemi...

Protein and FAA contents were linearly related to dry body mass, and were independent of rearing temperature between 14 and 18 °C.
