“…Nevertheless, growth enhancement with temperature might also present some disadvantages, because faster larval growth was accompanied by an increase in the incidence of skeletal deformities. Indeed, temperature is known to be one of the most important environmental factors that can induce morphological deformities during fish development (Aritaki and Seikai, 2004;Georgakopoulou et al, 2010;Dionísio et al, 2012). Additionally, pH may also affect the prevalence of fish skeletal deformities (Lall and Lewis-McCrea, 2007).…”

Early life stages of many marine organisms are being challenged by rising seawater temperature and CO 2 concentrations, but their physiological responses to these environmental changes still remain unclear. In the present study, we show that future predictions of ocean warming (+4°C) and acidification (ΔpH=0.5 units) may compromise the development of early life stages of a highly commercial teleost fish, Solea senegalensis. Exposure to future conditions caused a decline in hatching success and larval survival. Growth, metabolic rates and thermal tolerance increased with temperature but decreased under acidified conditions. Hypercapnia and warming amplified the incidence of deformities by 31.5% (including severe deformities such as lordosis, scoliosis and kyphosis), while promoting the occurrence of oversized otoliths (109.3% increase). Smaller larvae with greater skeletal deformities and larger otoliths may face major ecophysiological challenges, which might potentiate substantial declines in adult fish populations, putting in jeopardy the species' fitness under a changing ocean.

“…The development of these skeletal deformities is not well understood and may be related to nutritional, environmental and genetic factors (Fernández et al, 2008;Boglione et al, 2014). Many researchers have proposed a variety of abiotic factors, such as environmental temperature, high swimming activity, photoperiod, tank colour, water temperature (Tandler et al, 1995;Kihara et al, 2002;Trotter et al, 2003;Sfakianakis et al, 2006;Cobcroft and Battaglene, 2009;Georgakopoulou et al, 2010;Prestinicola et al, the skeletal deformities downgrade the biological performance of the reared fish and the image of the final product, both negatively affecting the production cost and the market value (Divanach et al, 1996;Boglione et al, 2014). A 50% reduction of skeletal anomalies could save European aquaculture D 25,000,000 per year, while the estimated minimum annual loss due to skeletal anomalies is more than D 50,000,000 (Hough, 2009;Boglione et al, 2013a).…”

“…Furthermore, deformation can negatively impact fish growth, survival, swimming, food conversion, and susceptibility to stress and pathogens (Andrades et al 1996;Koumoundourous et al 1997;Boglione et al 2001). Though the rearing environment (e.g., temperature, salinity, water current, dissolved oxygen, and tank color) (Koumoundouros et al 1999(Koumoundouros et al , 2001Hattori et al 2004;Sfakianakis et al 2004;Okamoto et al 2009;Georgakopoulou et al 2010;Owen et al 2012), genetic factors (Ferguson and Danzmann 1998;Castro et al 2007;Ma et al 2014c), parasites and pesticides (Kusuda and Sugiyama 1981;Liang et al 2012;Liu et al 2012) can affect fish bone development, more and more evidence has demonstrated that nutritional factors during larval fish rearing can directly cause fish deformity (Andrades et al 1996;Afonso et al 2000;Cahu et al 2003a;Sandel et al 2010).…”

The retinoid X receptors (RXRs) are involved in the skeletal development and other biological process such as blood vessel formation and metabolism. Partial sequences of RXRα and β genes were obtained, and their expressions were quantified on golden pompano Trachinotus ovatus at 28 days post hatching (DPH) to explore the molecular response to nutritional manipulation in fish larvae. As live food, Artemia nauplii were separately enriched with Nannochloropsis and Algamac 3080 and non-enriched Artemia nauplii (control) for fish feeding. The expressions of RXRs were detected in the embryos and fish larvae at early stages, suggesting that the skeletal development in golden pompano initiated before yolk re-sorption completion. Fish fed non-enriched Artemia nauplii ended up with higher jaw malformation. The highest specific growth rate was obtained when fish were fed with the Artemia nauplii enriched with Algamac 3080, and the lowest growth rate was observed when fish were fed with unenriched Artemia nauplii. The highest survival was obtained when fish were fed with non-enriched or Nannochloropsis-enriched Artemia nauplii. This study indicates that the use of enriched formula for Artemia nauplii can significantly affect the expression levels of RXRs and jaw malformation of golden pompano larvae, but there is no clear correlation between RXRs expressions and malformation rates when fish are subjected to nutrient challenge.
