Early Feeding by Cultured Paralarvae of Octopus sinensis d’Orbigny 1841: Comparison of Survival, and Fatty Acid and Amino Acid Profiles, Using Two Species of Artemia

Abstract:

Experiments were performed to compare the effect on survival patterns of early paralarvae of the East Asian common octopus, Octopus sinensis d’Orbigny 1841, fed with one of two species of Artemia. Comparison of predator and prey nutritional content (amino acids and fatty acids) revealed that O. sinensis paralarvae raised on Artemia are relatively deficient in b-alanine, cysteine, carnitine and 20:01 unsaturated fatty acid. Using Artemia tibetiana Abatzopoulos, Zhang & Sorgeloos 1998 as sole prey resulted in better survival than with Artemia franciscana Kellog 1906 but the latter has better supply and pricing reliability and consistency in hatching. Feeding paralarvae on A. franciscana supplemented with a microalgal culture resulted in a survival pattern similar to that when paralarvae were fed with unsupplemented A. tibetiana. Therefore, future feed development will be based around amino acid supplementation of A. franciscana grown with microalgae.
