Melatonin effects on the hypothalamo–pituitary axis in fish
267
TL;DR: Studies of the targets and modes of action of melatonin in fish, and their parallels in mammals, are of interest to the understanding of time-related neuroendocrine regulation and its evolution from fish to mammals, as well as for aquacultural purposes.

Abstract: Melatonin, a hormonal output signal of vertebrate circadian clocks, contributes to synchronizing behaviors and neuroendocrine regulations with the daily and annual variations of the photoperiod. Conservation and diversity characterize the melatonin system: conservation because its pattern of production and synchronizing properties are a constant among vertebrates; and diversity because regulation of both its synthesis and modes of action have been profoundly modified during vertebrate evolution. Studies of the targets and modes of action of melatonin in fish, and their parallels in mammals, are of interest to our understanding of time-related neuroendocrine regulation and its evolution from fish to mammals, as well as for aquacultural purposes.

Melatonin-synthesizing enzymes in pineal, retina, liver, and gut of the goldfish (Carassius): mRNA expression pattern and regulation of daily rhythms by lighting conditions.
Elena Velarde,José Miguel Cerdá-Reverter,Ángel Luis Alonso-Gómez,Elisa Sánchez,Esther Isorna,María Jesús Delgado +5 more
TL;DR: The current results show circadian rhythms in Aanat-2 and Hiomt-2 transcripts in liver and hindgut, suggesting a local melatonin synthesis in goldfish and support the existence of melatonin synthesized in gut and liver of the goldfish.
Feeding behavior and the effect of photoperiod on the performance and hematological parameters of the pacamã catfish (Lophiosilurus alexandri)
Alexandre Takio Kitagawa,Leandro Santos Costa,Renan Rosa Paulino,Ronald Kennedy Luz,Priscila Vieira Rosa,Bartira Guerra-Santos,Rodrigo Fortes-Silva +6 more
TL;DR: It is suggested that a recently introduced fish in freshwater Brazilian aquaculture, Lophiosilurus alexandri, should be fed at night although they have the plasticity to adapt to other feeding schedules.

Synchronization to light and restricted-feeding schedules of behavioral and humoral daily rhythms in gilthead sea bream (sparus aurata)
José Fernando López-Olmeda,A. Montoya,Catarina C. V. Oliveira,Francisco Javier Sánchez-Vázquez +3 more
TL;DR: The role of feeding on endocrine and metabolic rhythms is highlighted, suggesting that feeding behavior should be considered when studying these variables.

A review of the melatonin functions in zebrafish physiology
Elena Lima-Cabello,María E. Díaz-Casado,José Antonio Esquivel Guerrero,Beatriz Baño Otalora,Germaine Escames,Luis C. López,Russel J. Reiter,Darío Acuña-Castroviejo +7 more
TL;DR: The purpose of this review was to update the current knowledge on the synthesis and biological functions of melatonin in zebrafish, keeping in mind its relevance not only in the physiology of the animal, but also in pathophysiological conditions.

Environmental chemicals affect circadian rhythms: An underexplored effect influencing health and fitness in animals and humans.
TL;DR: In this paper, a review of 40 natural and anthropogenic environmental circadian disrupters in fish is presented, which can be divided into six major categories: steroid hormones, metals, pesticides and biocides, polychlorinated biphenyls, neuroactive drugs and other compounds such as cyanobacterial toxins and bisphenol A.

Coordination of circadian timing in mammals
TL;DR: Circadian rhythms are generated by one of the most ubiquitous and well-studied timing systems and are tamed by a master clock in the brain, which coordinates tissue-specific rhythms according to light input it receives from the outside world.

Cellular Mechanisms of Melatonin Action
TL;DR: Molecular mechanisms of the melatonin effects are not clear but may involve at least two parallel transduction pathways, one inhibiting adenylyl cyclase and the other regulating phospholipide metabolism and [Ca2+]i.

Does light have an influence on fish growth
TL;DR: A review of the present knowledge on the involvement of light influence on hormone levels (melatonin, somatotropin, thyroid hormones and other hormones) and a discussion about the endolymph–otolith system, which is very sensitive to daylight and seasonal cycles.
