Teleosts are the largest and most diverse group of vertebrates, and many species undergo
morphological, physiological, and behavioral transitions,“metamorphoses,” as they progress …

In adult vertebrates, glucocorticoids are thought to trigger transitions between life history
stages within breeding cycles. This review explores possible roles of glucocorticoids as …

Using zebrafish embryos and larvae, we examined the temporal patterns of cortisol and
expression of genes involved in corticosteroid synthesis and signaling. Embryonic cortisol …

Plasma cortisol levels have been used to evaluate the stress response in a variety of
cultured fish species. However, little is known about the stress response of zebrafish, Danio …

Teleost fish are more diverse than any other vertebrate group, and yet only a limited number
of species are fished and farmed globally. Efforts to expand the quantity and diversity of fish …

The corticotropin-releasing factor (CRF) system in fish functions to maintain homeostasis
during stress in part by regulating cortisol production via the hypothalamus–pituitary …

The essential roles of thyroid hormone (TH) in perinatal brain development have been
known for decades. More recently, many of the molecular mechanisms underlying the …

Most teleost fishes exhibit a biphasic life history with a larval oceanic phase that is
transformed into morphologically and physiologically different demersal, benthic, or pelagic …

The stress response is a normal reaction to a real or perceived threat. However, stress
response systems that are overwhelmed or out of balance can increase both the incidence …

While sexual dimorphism in immune responses has been documented in other vertebrates,
evidence for a similar phenomenon in fish is lacking. Here, we review the relationship …
