Patterns of Occurrence of the Platyhelminth Parasites of the Wild Bullseye Puffer (Sphoeroides annulatus) Off Sinaloa, Mexico

Journal of Parasitology, 2004
This study provides basic information on the occurrence of platyhelminths in the wild bullseye puffer (Sphoeroides annulatus) from Sinaloa, Mexico. Specimens of pufferfish were collected from 2 localities: Teacapan (n = 161) and Mazatlan (n = 66). Six species of platyhelminths were recorded: 2 monogeneans (Diclidophoridae: Heterobothrium ecuadori and ...

Efecto de la temperatura y salinidad del agua en la incubación de huevos de botete diana Sphoeroides annulatus

open access: yesRevista De Biologia Marina Y Oceanografia, 2012
The effects of different water temperatures (22, 25, 28 and 31ºC) and salinities between 0 and 60 psu (with intervals of 5 psu) on egg incubation of the bullseye puffer (Sphoeroides annulatus) were evaluated in this study.

Reproductive biology of the bullseye puffer Sphoeroides annulatus: Gonadosomatic index and its suitability for estimating length at maturity

Journal of Fish Biology, 2022
AbstractThis study aimed to describe updated information on the basic reproductive biology of Sphoeroides annulatus females and potential use of the gonadosomatic index as input data to assess length at 50% maturity () and identify the breeding season.

Expression of a glycoprotein hormone receptor gene in the ovary of the bullseye puffer (Sphoeroides annulatus)

Fish Physiology and Biochemistry, 2003
A fragment of a glycoprotein hormone receptor (GpHR) gene was isolated from the ovary of the bullseye puffer. This cDNA fragment showed similarity to the thyrotropin (TSH) and gonadotropin (LH and FSH) receptors. GpHR mRNA expression in the ovary gradually increased during oocyte maturation.
