Feed is one of the most important external signals in fish that stimulates its feeding behavior
and growth. The intake of feed is the main factor determining efficiency and cost, maximizing …

In the last decade, the concept of animal stress has been stressed thin to accommodate the
effects of short-term changes in cell and tissue physiology, major behavioral syndromes in …

The regulation of food intake in fish is a complex process carried out through several
different mechanisms in the central nervous system (CNS) with hypothalamus being the …

Evidence indicates that central regulation of food intake is well conserved along the
vertebrate lineage, at least between teleost fish and mammals. However, several differences …

Fishes are exposed to natural and anthropogenic changes in their environment, which can
have major effects on their behaviour and their physiology, including feeding behaviour …

Neuropeptide Y family (NPY) is a potent orexigenic peptide and pancreatic polypeptide
family comprising neuropeptide Y (Npy), peptide YYa (Pyya), and peptide YYb (Pyyb), which …

Subtropical fish are exposed to seasonal variations in temperature that impose a set of
adaptations on their metabolism necessary for the maintenance of homeostasis. In this …

The pineal organ of all vertebrates synthesizes and secretes melatonin in a rhythmic manner
due to the circadian rhythm in the activity of arylalkylamine N-acetyltransferase (AANAT)–the …

Part of the life cycle of several fish species includes important salinity changes, as is the
case for the sea bass (Dicentrarchus labrax) or the Atlantic salmon (Salmo salar). Salmo …

In mammalian research, the implementation of the 3Rs is ubiquitous. However, the
adaptation of procedures for experimental work on fish seems less extensive in comparison …
