“…The first direct evidence of the actions of CCK on feeding was provided by injections in goldfish (Himick and Peter, 1994), followed by cloning of goldfish CCK cDNA (Peyon et al, 1998) and the demonstration of periprandial variations in CCK mRNA expression levels (Peyon et al, 1999). Subsequently, a number of studies have characterized CCK in several fish, including other Cypriniformes (e.g., common carp Zhong et al, 2013; zebrafish Koven and Schulte, 2012; Tian et al, 2015; grass carp; blunt snout bream Ping et al, 2013; Ji et al, 2015), Characiformes (e.g., cavefish Wall and Volkoff, 2013, dourado Pereira et al, 2015; Volkoff et al, 2016, thin dogfish Oligosarcus hepsetus Vieira-Lopes et al, 2013, pirapitinga Volkoff, 2015a, red-bellied piranha Volkoff, 2014a, pacu Volkoff et al, 2017), Salmoniformes (e.g., Atlantic salmon Valen et al, 2011), Gadiformes (Atlantic cod Tillner et al, 2013), Perciformes [e.g., yellowtail (Furutani et al, 2013; Hosomi et al, 2014); Astatotilapia burtoni (Grone et al, 2012); cunner (Babichuk and Volkoff, 2013; Hayes and Volkoff, 2014); sea bass (Tillner et al, 2014); yellow croaker ( Larimichthys crocea ) (Cai et al, 2015); white sea bream, Diplodus sargus (Micale et al, 2012, 2014)], Pleuronectiformes (e.g., winter flounder (MacDonald and Volkoff, 2009a), Atlantic halibut Kamisaka et al, 2001, olive flounder Kurokawa et al, 2000) and Siluriformes (channel catfish Peterson et al, 2012). …”

The Neuroendocrine Regulation of Food Intake in Fish: A Review of Current Knowledge

Fish are the most diversified group of vertebrates and, although progress has been made in the past years, only relatively few fish species have been examined to date, with regards to the endocrine regulation of feeding in fish. In fish, as in mammals, feeding behavior is ultimately regulated by central effectors within feeding centers of the brain, which receive and process information from endocrine signals from both brain and peripheral tissues. Although basic endocrine mechanisms regulating feeding appear to be conserved among vertebrates, major physiological differences between fish and mammals and the diversity of fish, in particular in regard to feeding habits, digestive tract anatomy and physiology, suggest the existence of fish- and species-specific regulating mechanisms. This review provides an overview of hormones known to regulate food intake in fish, emphasizing on major hormones and the main fish groups studied to date.

“…The larvae were kept in the dark until first feeding at 7 dph and under a natural photoperiod regime (16L:8D) thereafter. For further details, see Tillner, Rønnestad, Dhert and Uebersch€ ar (2014). The sea bass larvae were fed on rotifers (Brachionus plicatilis) from 7 dph on.…”

Immunostimulatory effects of dietary poly-β-hydroxybutyrate in European sea bass postlarvae

et al. 2017

View full text Add to dashboard Cite

The stable production of high‐quality fry in marine aquaculture is still hampered by unpredictable mortality caused by infectious diseases during larval rearing. Consequently, the development of new biocontrol agents is crucial for a viable aquaculture industry. The bacterial energy storage compound poly‐β‐hydroxybutyrate (PHB) has been shown to exhibit beneficial properties on aquatic organisms such as enhanced survival, growth, disease resistance and a controlling effect on the gastrointestinal microbiota. However, the effect of PHB on the developing immune system of fish larvae has so far not been investigated. In this study, the effect of feeding PHB‐enriched Artemia nauplii on survival, growth and immune response in European sea bass (Dicentrarchus labrax) postlarvae was examined. Amorphous PHB was administered to 28‐day‐old sea bass postlarvae over a period of 10 days. The survival and growth performance were monitored, and the expression of 29 genes involved in immunity, growth, metabolism and stress‐response was measured. While the expression of the insulin‐like growth factor 1 (igf1), an indicator of relative growth, was upregulated in response to feeding PHB, the larval survival and growth performance remained unaffected. After 10 days of PHB treatment, the expression of the antimicrobial peptides dicentracin (dic) and hepcidin (hep) as well as mhc class IIa and mhc class IIb was elevated in the PHB fed postlarvae. This indicates that PHB is capable of stimulating the immune system of fish early life stages, which may be the cause of the increased resistance to diseases and robustness observed in previous studies.

“…Effects of live feed properties (size, availability, quality) were addressed for turbot (P erez Benavente & Gatesoupe 1988;Gatesoupe 1990;Cunha & Planas 1999), sea bass (Infante et al 1996;Georgalas et al 2007), halibut (Gulbrandsen 1991(Gulbrandsen , 1993Olsen et al 1999) and cod (Puvanendran & Brown 1999;Puvanendran et al , 2004Folkvord et al 2010). Fine-tuning of feeding protocols (first feeding, diet transitions, weaning) was reported for turbot (Bromley 1978), sea bass (Barahona-Fernandes & Girin 1976;Barnab e & Guissi 1993;Cahu & Infante 1994;Barahona-Suzer et al 2011;Tillner et al 2014), halibut Naess et al 2001;Murray et al 2010) and cod (Baskerville-Bridges & Kling 2000b;Callan et al 2003;Shields et al 2003;Fletcher et al 2007;van der Meeren et al 2007). Light (intensity, spectrum, photoperiod) was a focus in 17 studies, four of which reported behavioural effects from light, in turbot (Champalbert & Le Direach-Boursier 1998), sea bass (Villamizar et al 2011b) and halibut (Gulbrandsen 1996;Karlsen & Mangor-Jensen 2001), respectively.…”

The aim of this review was to examine practices in academic research focusing on production of larvae of European marine fish species. The literature spanned peer‐reviewed articles over the years 1977–2014 for the main commercially produced marine species: Atlantic cod, halibut, sea bream, sea bass and turbot. Search hits were categorized into the main themes basic biology, natural habitat studies and aquaculture, and the latter theme further subdivided into nutrition, health, reproduction and production factor studies. In total, 74 of the production factor studies were thoroughly examined in terms of overall research structure, study designs, methods, analyses and reporting practices. A picture of a fragmented whole with many isolated contributors and limited cooperation appeared, and despite the multivariate nature and high complexity of the area, isolated and low replicated studies focusing on one variable at the time dominated. Randomization and blinding procedures were rarely accounted for, and a need to standardize practical conduct of research in terms of physical infrastructure, biological material used, control of tank environment, sampling, tank tending and response measurements appeared. Issues of statistical analysis were also apparent, spanning the choice of main techniques and follow‐up contrast procedures and Pseudoreplication. Additionally, the reporting of designs, analyses and results was often incomplete. Consequences of the different issues are discussed, and possible remedies proposed. The findings are in accordance with conclusions from contemporary studies addressing scientific quality and methodological issues at other areas of research.
