Xenotoca eiseni (Cyprinodontiformes, Goodeidae) as a Potential New Model for Studies on Maternal Transfer of Environmental Contaminants

The studies presented provide a foundation of data for the use of X. eiseni as a new model for studies on maternal transfer in ecotoxicology, however, further work is required to elucidate more about sensitivity and maternal transfer efficacy in this species.

Conserved form and function of the germinal epithelium through 500 million years of vertebrate evolution

The fact emerged that germinal epithelia occur in the gonads of all vertebrates examined herein of both sexes and has the same form and function across all vertebrate taxa.

Morphological basis for maternal nutrient provision to embryos in the viviparous fish Ataeniobius toweri (Teleostei: Goodeidae)

In viviparous Mexican fishes of the family Goodeidae, embryos develop in the maternal ovarian lumen. They typically absorb maternal nutrients during gestation by means of “trophotaeniae,” that is,

Structure of the testis and spermatogenesis of the viviparous teleost Poecilia mexicana (Poeciliidae) from an active sulfur spring cave in Southern Mexico

The histological characteristics of the testis and spermatogenesis of the cave molly Poecilia mexicana are described, and it is suggested that the viviparous condition where the spermatozoa enter in the female without been in the water, have allowed them to invade sulfurous and/or subterranean environments in Southern Mexico, without requiring complex morphofunctional changes in theTestis or the sperMatogenetic process.

Reproductive biology of Goodea atripinnis (Jordan, 1880) (Cyprinodontiformes: Goodeidae) under controlled conditions.

A high reproductive potential is demonstrated in G. atripinnis under controlled conditions in the Aguascalientes state and females compared with males, reached a higher TW and TL.

Ultrastructural Aspects of Spermatogenesis in Phalloceros caudimaculatus (Teleostei, Poeciliidae)

El objetivo del presente estudio fue analizar los aspectos ultraestructurales de la espermatogenesis en Phalloceros caudimaculatus, durante el periodo de proliferacion celular. El parenquima

Ovarian structure and oogenesis of the extremophile viviparous teleost Poecilia mexicana (Poeciliidae) from an active sulfur spring cave in Southern Mexico

The ovary and oogenesis of Poecilia mexicana are similar to these seen in other poeciliids, but the authors found frequent atretic follicles, melanomacrophage centers, reduced fecundity and increased of offspring size.

Activity of the ovarian germinal epithelium in the freshwater catfish, Pimelodus maculatus (Teleostei: Ostariophysi: Siluriformes): Germline cysts, follicle formation and oocyte development

The findings in P. maculatus reinforce the hypothesis that ovarian follicle formation represents a conserved process throughout vertebrate evolution.

Germinal epithelium, folliculogenesis, and postovulatory follicles in ovaries of rainbow trout, Oncorhynchus mykiss (Walbaum, 1792) (Teleostei, protacanthopterygii, salmoniformes)

The rainbow trout, Oncorhynchus mykiss (Walbaum, 1792), is a salmoniform fish that spawns once per year. Ripe females that had ovulated naturally, and those induced to ovulate using salmon

Morfología ovárica y foliculogénesis en Gymnotus carapo (Linnaeus, 1758)

El objetivo del presente trabajo fue el estudio de la morfología ovárica y la foliculogénesis de Gymnotus carapo, a fin de aportar información sobre su biología reproductiva, y que ésta sea de



Testis Structure in Three Species of Teleosts with Tubular Gonopodia

The evolution of tubular gonopodia comprises an alternate mechanism of sperm transfer whose efficiency is not diminished because sperm are not "packaged" as spermatozeugmata or spermatophores, in both Anableps anableps and Jenynsia lineata.

Spawning rhythms of common snook in Florida

Common snook Centropomus undecimaliswere sampled monthly from the Jupiter–Lake Worth area of Florida's Atlantic coast during 1989 and 1991 (1452 fish) and from Tampa Bay on Florida's Gulf of Mexico
