Summary
This review explores melatonin
Area of Science:
- Comparative Endocrinology
- Chronobiology
Background:
- Melatonin is a conserved vertebrate hormone regulating daily and annual rhythms.
- Understanding melatonin's role in photoperiodic effects is crucial, especially in fish where knowledge is limited.
Purpose of the Study:
- To review current data on melatonin production, regulation, and receptors in fish.
- To synthesize information on melatonin's effects on fish neuroendocrine functions and behaviors.
- To discuss photoperiod manipulation for aquaculture applications.
Main Methods:
- Literature review of in vivo and in vitro studies.
- Analysis of data on melatonin production sites and mechanisms.
- Examination of melatonin receptor subtypes, location, and regulation.
Main Results:
- Identified key sites of melatonin production in fish.
- Detailed mechanisms controlling daily and annual melatonin rhythms.
- Characterized fish melatonin receptor subtypes and their regulation.
- Reviewed melatonin's impact on reproduction, growth, feeding, and behavior.
Conclusions:
- Melatonin plays a significant role in regulating fish physiology and behavior.
- Photoperiod manipulation via melatonin offers potential for aquaculture advancement.
- Further research is needed to fully elucidate melatonin's complex roles in fish.

01:02The Pineal Gland
The pineal gland, a diminutive endocrine structure named for its pinecone-shaped appearance, is situated atop the third ventricle within the diencephalon region of the forebrain. This gland, composed of secretory cells known as pinealocytes arranged in compact cords and clusters around dense particles of calcium salts, plays a pivotal role in hormonal regulation.
The primary secretion of the pineal gland is the hormone melatonin, derived from serotonin. The concentration of melatonin in the...

02:19Circadian Rhythms and Gene Regulation
The biological clock is involved in many aspects of regulating complex physiology in all animals. It was in 1935 when German zoologists, Hans Kalmus and Erwin Bünning, discovered the existence of circadian rhythm in Drosophila melanogaster. However, the internal molecular mechanisms behind the circadian clock remained a mystery until 1984, when Jeffrey C. Hall, Michael Rosbash, and Michael W. Young discovered the expression of the Per gene oscillating over a 24-hour cycle. In subsequent years,...
01:19Management of Insomnia
The sleep cycle, an integral part of human health, consists of several stages with distinct characteristics and functions. It begins with a transition from wakefulness to sleep, known as the light sleep phase, followed by the restorative deep sleep phase, essential for physical recovery and growth. The cycle concludes with the Rapid Eye Movement (REM) phase, characterized by high brain activity and vivid dreaming. Insomnia, a prevalent sleep disorder, involves difficulty falling asleep, staying...
02:32Osmoregulation in Fishes
When cells are placed in a hypotonic (low-salt) fluid, they can swell and burst. Meanwhile, cells in a hypertonic solution—with a higher salt concentration—can shrivel and die. How do fish cells avoid these gruesome fates in hypotonic freshwater or hypertonic seawater environments?
02:45Biological Clocks and Seasonal Responses
The circadian—or biological—clock is an intrinsic, timekeeping, molecular mechanism that allows plants to coordinate physiological activities over 24-hour cycles called circadian rhythms. Photoperiodism is a collective term for the biological responses of plants to variations in the relative lengths of dark and light periods. The period of light-exposure is called the photoperiod.
01:11Understanding Sleep
Sleep, an essential biological state, involves significant reductions in physical activity, sensory awareness, and interaction with the environment. This complex physiological process is primarily regulated by specific brain regions, notably the hypothalamus and pons, which govern the sleep-wake cycle or circadian rhythm.
The circadian rhythm, a nearly 24-hour cycle, is deeply influenced by environmental light cues. Light exposure directly affects the hypothalamus, which in turn regulates...
