Seasonality of Parasitic Copepods on Bullseye Puffer, Sphoeroides annulatus (Pisces: Tetraodontidae), From the Northwestern Coast of Mexico [PDF]
Seasonal occurrence of parasitic copepods in wild bullseye puffer, Sphoeroides annulatus (Pisces: Tetraodontidae), was analyzed in conjunction with variation of biotic and abiotic factors. Eleven samples were taken between February 2007 and February 2008 in Santa María La Reforma lagoon (northwestern coast of México). In total, 337 fish was examined; 5

Advances in the culture of the Mexican bullseye puffer fish Sphoeroides annulatus, Jenyns (1842)
This paper provides a brief description of the natural history known of the genus Sphoeroides as an introduction to the biology of Mexican puffer fish Sphoeroides annulatus Jenyns (1842). Studies to determine the culture potential of this species during 11 years are described. At the experimental level, useful advances have been made on S.

Occurrence of Sphoeroides rosenblatti Bussing, 1996 (Teleostei: Tetraodontidae) along the coast of Guayas Province, Ecuador, and a comparison with sympatric Sphoeroides annulatus (Jenyns, 1842) [PDF]
Se recolectaron trece ejemplares juveniles de Sphoeroides rosenblatti Bussing, 1996 en un bosque pequeno y fuertemente impactado de mangle situado en Palmar, provincia de Guayas, Ecuador. Esta especie era conocida previamente solo de aguas costeras de Costa Rica y Panama. Se contrasto la ocurrencia y morfologia de S.

First attempts at culturing Sphoeroides annulatus (bullseye puffer fish) resulted in recurrent parasitic infestations caused by the monogenea Heterobothrium ecuadori and the dinoflagellate Amyloodinium ocellatum, both of which are associated to mortality events in other cultured species.

Kudoa dianae sp. n. (Myxosporea: Multivalvulida), a new parasite of bullseye puffer, Sphoeroides annulatus (Tetraodontiformes: Tetraodontidae) [PDF]
A new multivalvulid myxosporean species, Kudoa dianae sp. n., is described from bullseye puffer, Sphoeroides annulatus (Jenyns) (Tetraodontiformes: Tetraodontidae). Plasmodia develop in extramuscular sites, in the wall of oesophagus and less frequently on mesenteries.

Reproductive aspects of Sphoeroides annulatus (Jenyns, 1842) (Tetraodontiformes, Tetraodontidae) inhabiting the Mazatlan coast, Sinaloa, Mexico [PDF]
La muestra de Sphoeroides annulatus capturada en la costa de Mazatlan, Sinaloa, Mexico fue predominantemente de adultos, como resultado de una aparente distribucion diferencial por talla/edad de la especie. La proporcion sexual fue 1:1. Las hembras presentaron un crecimiento alometrico y los machos, isometrico. De acuerdo con el analisis morfocromatico
