Abstract Purpose of Review Fishes exhibit the greatest biodiversity among extant
vertebrates. In fact, about 34,000 fish species are currently estimated, of which~ 25% are …

Sturgeon and paddlefishes (Acipenseriformes) are cultured worldwide for commercial and
conservation purposes. Over the past decade, we have learned many sturgeon culture …

Triploidization is an interesting tool to produce sterile fish. In the yellowtail tetra, Astyanax
altiparanae, this can be applied for aquaculture and surrogate technologies. In this study, we …

Whole genome duplication is hypothesized to have played a critical role in the evolution of
several major taxa, including vertebrates, and while many lineages have rediploidized …

Astyanax is a species-rich polyphyletic genus distributed between the southern United
States and central Argentina. The genus contains groups of cryptic species, which are …

In fish, many factors can affect reproduction during in vitro fertilization, therefore
determination of the factors that affect affecting gamete quality is needed. However, few …

Background The main cytogenetic studies of the Characidae family comprise the genera
Astyanax and Psalidodon involving the use of repetitive DNA probes. However, for the …

Individuals of Astyanax bockmanni from one population belonging to the Paranapanema
River basin, southeastern Brazil, were cytogenetically examined. In the present paper, we …

Triploidization is a technique to produce sterile fish on a large scale. In the spotted catfish
Pimelodus maculatus, sterile fish serve as a host of germ cell transplantation for subsequent …

In this study we analyzed whether the in vivo storage of oocytes (time after ovulation until
fertilization) affects the survival and the ploidy status of the yellowtail tetra Astyanax …
