“…Circulating plasma prolactin levels in the sea bream have not been reported. However, based on the secretion pattern and pituitary content (Brinca et al, 2003;Fuentes et al, 2010a) the levels of prolactin in sea bream plasma are likely to be within the range described for other species. The bicarbonate secretion responses of the anterior intestine to basolateral prolactin revealed a significant threshold effect at the physiological level of 10ngml -1 , with inhibition of bicarbonate secretion of around 40% (Fig.3B).…”

“…For example in gilthead sea bream, where PRL‐receptor (PRLR) are also found in the skin (Santos et al. 2001), E 2 administration stimulated pituitary PRL secretion in winter (Brinca et al. 2003) but also transcription of PRLR in gonads of maturing fish while reducing them 24‐fold in juvenile gonads (Cavaco et al.…”

“…Conversely, sex steroid feed-back on PRL synthesis and sensitivity varied according to the reproductive stage and/or season. For example in gilthead sea bream, where PRL-receptor (PRLR) are also found in the skin (Santos et al 2001), E 2 administration stimulated pituitary PRL secretion in winter (Brinca et al 2003) but also transcription of PRLR in gonads of maturing fish while reducing them 24-fold in juvenile gonads (Cavaco et al 2003). In primary pituitary cell culture of masu salmon, E 2 and 11-KT significantly increased the amounts of PRL and SL messenger RNAs (mRNAs) at the pre-spawning stage in the female (July) but halved them during the spawning period in September (Onuma et al 2005).…”

Morphological skin colour changes in teleosts

Morphological skin colour change in fish is often referred to in the sole context of background adaptation. It is becoming increasingly apparent that it is a broad phenomenon elicited by a variety of factors. To date, no review has attempted to integrate the different types of morphological colour changes occurring in teleosts, their ecological origins and the regulatory mechanisms involved, often restricting the view on the subject. First, the origin of skin colour is addressed in teleosts including chromatophore type and distribution, pigment biosynthetic pathways and their interactions to one-another. Second, the different types of morphological colour changes occurring in teleosts are categorized and a key distinction is made between proximate and ultimate morphological colour changes. These are defined respectively as the change of phenotype during an established life-stage in response to environmental interactions and during the transition between two developmental-stages phenotypically pre-adapted to their ancestral ecosystems. Nutrition and UV-light are primary factors of proximate morphological colour changes beyond the control of the organism. By contrast, background light conditions and social interactions are secondary proximate factors acting through the control of the organism. Highly diversified among teleosts, ultimate morphological skin colour changes are presented in term of alterations in skin structure and pigment deposition during metamorphosis in different species. Finally, the physiological and endocrine mechanisms regulating both proximate and ultimate morphological colour changes are reviewed

“…Both peptides stimulate the release of GH, gonadotropin, prolactin, and somatolactin from cultured pituitary cells of teleosts in vitro. [68][69][70][71] However, the physiological functions of PACAP and VIP in the central nervous system of teleosts have not yet been clarified. Previous studies have shown that ICV injection of PACAP and VIP inhibits feeding in mouse 8 and chick.…”

The hypothalamus, limbic system, and brainstem play an important role in the regulation of instinctive behavior. Many kinds of hypothalamic neuropeptides, such as orexin, ghrelin, neuropeptide Y, melanin-concentrating hormone, pituitary adenylate cyclase-activating polypeptide, corticotropin-releasing hormone, and diazepam-binding inhibitor-derived peptides, including the octadecaneuropeptide, have been implicated in the regulation of appetite and energy homeostasis in various models, including rodents and goldfish. Several of these neuropeptides also influence locomotor or psychomotor activity in rats and mice. The aim of this paper is to review the current knowledge on the psychophysiological effects of neuropeptides involved in the regulation of food intake in fish, and to examine their significance from a comparative point of view.
