“…Large variations in ingestion rates are observed in feeding experiments, and, in some cases, first-feeding marine fish larvae ingest artificial feed but fail to grow. Advances in this area have produced better results (9,13,29,31,34), but, in most species, problems arising from the use of formulated feeds at the onset of exogenous feeding still persist. The larvae of gilthead sea bream hatch from pelagic eggs, and full development of the digestive system only occurs at metamorphosis (40).…”

Sarropoulou, Elena, Georgios Kotoulas, Deborah M. Power, and Robert Geisler. Gene expression profiling of gilthead sea bream during early development and detection of stress-related genes by the application of cDNA microarray technology. Physiol Genomics 23: 182-191, 2005. First published July 26, 2005 doi:10.1152/physiolgenomics.00139.2005.-Large-scale gene expression studies were performed for one of the main European aquaculture species, the gilthead sea bream Sparus auratus L. For this purpose, a cDNA microarray containing 10,176 clones from a cDNA library of mixed embryonic and larval stages was constructed. In addition to its importance for aquaculture, the taxonomic position and the relatively small genome size of sea bream makes it a prospective model for evolutionary biology and comparative genomics. However, so far, no large-scale analysis of gene expression exists for this species. In the present study, gene expression was analyzed in gilthead sea bream during early development, a significant period in the determination of quantitative traits and therefore of considerable interest for aquaculture. Synexpression groups expressed primarily early and late in development were determined and were composed of both known and novel genes. Furthermore, it was possible to identify stress response genes induced by cortisol injections using the cDNA microarray generated. The creation of gene expression profiles for sea bream by microarray hybridization will accelerate identification of candidate genes involved in multifactorial traits and certain regulatory pathways and will also contribute to a better understanding of the genetic background of fish physiology, which may help to improve aquaculture practices. Sparus auratus; stress responseIN RECENT YEARS, much effort has been invested in developing genome resources. Continuous improvements in technology have allowed rapid progress in the functional interpretation of sequencing data and the investigation of gene expression. The development of technology in model species has paved the way for high-throughput studies at a molecular level of nonmodel organisms of evolutionary, environmental, or economic interest.The gilthead sea bream Sparus auratus is an organism of both economic and evolutionary interest, and it is one of the main European aquaculture species along with the Atlantic salmon (Salmo salar), rainbow trout (Oncorhynkus mykiss), oyster (Crassostrea gigas), and sea bass (Dicentrax labrax). In addition to a basic understanding of the biology and reproductive physiology of this species, well-characterized culture methodologies for its reproduction and rearing also exist. From an evolutionary viewpoint, the gilthead sea bream is of interest as it belongs to the Perciformes, an order that underwent an explosive radiation 60 million years ago and contains a large number of other teleost taxa.

“…This is of special relevance to the goal of significant replacement of live feed by inert diets, which can be designed to satisfy specific nutritional requirements. Artificial diets are usually associated with reduced growth, malformations and higher stress susceptibility in feeding larvae due to low diet acceptance, combined with poor ingestion, digestion and assimilation, and lack of essential micronutrients (Koven et al, 2001;Cahu et al, 2003). The use of stable isotopes is a safe and useful technique that has been applied to determine nutrient incorporation from different dietary items in aquatic larval organisms (Schlechtriem et al, 2004;Jomori et al, 2008;Gamboa-Delgado et al, 2008;Le Vay and Gamboa-Delgado, 2010).…”

Larvae of sichel Pelecus cultratus (L.) were reared up on natural food (Artemia sp. nauplii), after a certain time replaced by dry feed (Perla -Skretting). The rearing was conducted in aquaria of the capacity of 50 dm 3 each working in a closed, water recirculation system. The sichel larvae were reared up for 21 days in five nutrition groups: P21 -dry feed only, A4P17 -4 days of Artemia larvae followed by 17 days of dry feed; A8P13 -8 days of Artemia nauplii followed by 13 days of dry feed; A12P9 -12 days of Artemia larvae followed by 9 days of dry feed, and A21-Artemia nauplii throughout the whole experiment. The assessment of the effect of substituting natural food with feed was based on the size reached by larvae, survivability, relative growth rate of individual fish larvae and body condition. The larvae fed on the dry feed and the ones which first received Artemia nauplii for the first 4 to 8 days presented the smallest gain, which suggests that natural food should be given to sichel larvae for at least the first 12 days of rearing
