“…23 Since RA was used for enrichment of Artemia in our previous study, it is not possible to compare these results directly with the present results. However, similar observations showed two peaks for RA at 6 and 18 h after enrichment in Artemia enriched with both RA 24 and VAp. Thus, there is a 12-h interval in increase in RA content in Artemia when they are enriched with either RA or RA precursor.…”

The dynamics of vitamin A (VA) compounds in live food during enrichment were examined under different light conditions. Rotifers Brachionus plicatilis and Artemia nauplii (Artemia) were enriched with or without 10 mg VA palmitate (VAp) in 1 L of culture medium for 24 h under either bright (2000 lx), or dark (<1 lx) conditions. VAp, retinol (ROH), retinal (RAL) and retinoic acid (RA) contents were analyzed at 0 h (before enrichment) and at 3, 6, 12, 18 and 24 h after the onset of enrichment. Retinoid content in rotifers enriched in darkness was always higher than that enriched under light. VAp content showed two peaks at 3 and 18 h in rotifers enriched in darkness, but it showed one peak at 3 h in rotifers enriched under light. ROH and RA contents increased over the 24-h period in rotifers enriched in darkness, whereas they decreased 12 h onward in rotifers enriched under light. In Artemia, VAp and ROH contents were always higher than when enriched under the bright condition, but their dynamics showed a similar pattern in Artemia enriched under dark and bright conditions.

“…Unlike in immersion studies where larvae are continuously exposed to a consistent concentration of vitamin A, in feeding studies larvae shown a clear sharp increase and decrease in vitamin A content that reflects the dietary intake of vitamin A and its subsequent absorption and metabolism. This is supported by the observation that the concentration of alltrans retinoic acid peaks 3 h after flounder larvae are fed Artemia enriched with all-trans retinoic acid, before declining to about one-third of the peak concentration 24 h after feeding [59].…”

Progress on larval and juvenile nutrition to improve the quality and health of seawater fish: a review

In seedling production of seawater fish, providing appropriate nutrition is a necessity for successful production of quality larvae and juveniles. Mass-produced live prey organisms, such as the rotifer Brachionus plicatilis species complex and brine shrimp Artemia spp., alone do not provide sufficient nutrition to the larvae and juveniles of seawater animals. This inadequacy has led to various problems related to fish quality and health, including increased incidence of morphological and behavioral abnormalities and mass mortalities. It is, therefore, important to identify the factors associated with these problems to improve seedling production techniques. This review collates the efforts made during the past two decades in larval nutrition-focusing on advances made in the use of certain nutrients, such as docosahexaenoic acid, vitamin A derivatives, and taurine that are important for the mass production of seawater fish larvae and juveniles-with an aim to improve the quality and health of fish.

“…); however, there are still important gaps of knowledge regarding the nutritional requirements for vitamins in fish larvae, and several studies seemed to indicate that the level of incorporation of vitamins in diets for fish larvae exceeds their nutritional needs, resulting in reduced growth, delayed maturation of the digestive system and a high incidence of skeletal anomalies (Haga et al . ,b; Villeneuve et al . ; Mazurais et al .…”

“…Regarding fish larvae and early juveniles, very few studies exist of the role of this vitamin on the development of skeletal anomalies. Haga et al (2004b) reported that early juveniles of Japanese flounder fed a dietary excess of vitamin D 3 (21 vs. 1.8 IU g À1 from the control diet) showed an increase in skeletal disorders mostly consisting in the winding of the vertebral bodies caused by abnormal calcification and impairment of their rigidity. In a recent study of European seabass fed microdiets containing graded levels of vitamin D 3 (11, 28, 42 and 140 IU g À1 diet), Darias et al (2010) found an impact of dietary vitamin D 3 on the European seabass digestive system ontogenesis that consequently conditioned the ossification process and skeletogenesis.…”

The presence of skeletal anomalies in farmed teleost fish is currently a major problem in aquaculture, entailing economical, biological and ethical issues. The common occurrence of skeletal abnormalities in farmed fish and the absence of effective solutions for avoiding their onset or definitely culling out the affected individuals as early as possible from the productive cycle, highlight the need to improve our knowledge on the basic processes regulating fish skeletogenesis and skeletal tissues differentiation, modelling and remodelling. Severe skeletal anomalies may actually occur throughout the entire life cycle of fish, but their development often begins with slight aberrations of the internal elements. Comprehensive investigation efforts conducted on reared larvae and juveniles could provide a great contribution in filling the gap in knowledge, as skeletogenesis and skeletal tissue differentiation occur during these early life stages. The aim of this review is to provide a synthetic but comprehensive picture of the actual knowledge on the ontogeny, typologies and occurrence of skeletal anomalies, and on the proposed causative factors for their onset in larvae and juveniles of European farmed fish. The state-of-art of knowledge of these issues is analysed critically intending to individualize the main gaps of knowledge that require to be filled, in order to optimize the morphological quality of farmed juveniles.
