Fecha de publicación: | 2010 | Editor: | Oxford University Press | Citación: | ICES Journal of Marine Science 67(7): 1408-1412 (2010) | Resumen: | A molecular method was developed to detect Artemia franciscana within Octopus vulgaris paralarvae, as a first step towards understanding the diet of octopus during this life stage. Wild eggs were collected from a spawning female in the Ría de Vigo (northwestern Spain) in late summer, and brought to the laboratory. After hatching, paralarvae were reared in 30 l rectangular tanks with an open seawater filtered system. Paralarvae were fed Artemia, then immediately fixed in 80% ethanol and preserved at −20°C. Primers specific to A. franciscana were designed for the gene cytochrome c oxidase subunit I. A nested polymerase chain reaction was necessary to detect A. franciscana within octopus paralarvae. This molecular method provides a new framework for resolving the diet of cephalopod paralarvae in the wild, essential for ecological understanding and increasing survival rates in aquaculture | Descripción: | 8 páginas, 2 figuras, 1 tabla | Versión del editor: | http://dx.doi.org/10.1093/icesjms/fsq051 | URI: | http://hdl.handle.net/10261/48685 | DOI: | 10.1093/icesjms/fsq051 | ISSN: | 1054-3139 | E-ISSN: | 1095-9289 |
