Temperature is critical in regulating virtually all biological functions in fish. Low temperature
stress (cold shock/stress) is an often‐overlooked challenge that many fish face as a result of …

This review discusses the new biotechnological tools that are arising and promising for
conservation and enhancement of fish production, mainly regarding the endangered and the …

The aim of this study was to evaluate the growth, carcass yield, fatty acid composition, and
reproductive parameters of diploid and triploid Astyanax altiparanae. Triploidization was …

The use of model organisms is important for basic and applied sciences. Several laboratory
species of fishes are used to develop advanced technologies, such as the zebrafish (Danio …

The production of triploid yellowtail tetra Astyanax altiparanae is a key factor to obtain
permanently sterile individuals by chromosome set manipulation. Flow cytometric analysis is …

Primordial germ cells (PGCs) are embryonic pluripotent cells that can differentiate into
spermatogonia and oogonia, and therefore, PGCs are a genetic source for germplasm …

This study aimed to examine the gonadal morphology of diploid and triploid fish through
stereological analysis. Triploid individuals were obtained after temperature shock (40° C for …

Gynogenesis is a chromosome manipulation technique applicable on the production of all-
female populations, generation of inbred or clonal lines and identification of genetic sex …

Tetraploid fish are an important source of diploid gametes for polyploid production, and they
can be induced by inhibition of the first mitotic cell division. Dispite its potential, very few …

In this study, the aim was to establish a protocol for first feeding of diploid and triploid
yellowtail tetra Astyanax altiparanae in laboratory conditions. The fry were fed with five …
