Anormalidades durante el desarrollo embrionario de sardina común, Strangomera bentincki en el ambiente natural
To describe and quantify morphological abnormalities during the embryonic development of Strangomera bentincki an area nearby the Itata River mouth was sampled during the reproductive season 2007. Abnormality levels (3-13 %) were coincident with reported levels for other Clupeids species inhabiting...
