Coating with chitosan film of sea bream (Sparus aurata) fillets: determining shelf life in refrigerator conditions Ciênc. Tecnol. Aliment.
İZCİ,Levent; EKİCİ,Furkan; GÜNLÜ,Ali.
Abstract In the investigate, we objectived to assess the effect of coating with chitosan film on the shelf life. To this end, skinless sea bream fillets were separated as control group (C), vacuum packed (VP) and coated with chitosan film and vacuum packed (CF+VP). Samples of each group were periodically analyzed for microbiological [Total mesophilic aerobic count (TMAc) and Total psychrophilic aerobic count (TPAc)] and physicochemical [pH, Total volatile basic nitrogen (TVB-N), Thiobarbituric acid (TBA) and Trimethylamine nitrogen (TMA-N)] in storage time. It was determined that CF+VP had the highest shelf life among the sample groups. The findings of the study showed that covering sea bream fillets with chitosan film and vacuum packaging significantly...

Determination of some quality properties of marinated sea bream (Sparus Aurata L., 1758) during cold storage Ciênc. Tecnol. Aliment.
Kaya,Gülderen Kurt; Baştürk,Özden.
In this study, it was aimed to determine the effect of sea bream (Sparus aurata) marinated some quality properties during cold storage. The fillets of fish were immersed into brine including 3.5% acetic acid 11% salt in the ratio of 1: 1.5 (fish: marinate brine) for marination process. After the process of ripening, samples were grouped into two and packed in plastic containers; one being plain (in sunflower oil) and the other being sauced (sauced prepared with sunflower oil). During storage, sensory, crude protein, lipid, dry matter and crude ash, TBA, TVB-N, TMA-N and peroxide analyses were done periodically. According to results of 200 days of storage, TVB-N values of sea bream marinates packaged as plain and sauced were 15.86/14.89 mg/100g, TBA...

Etude de la qualité des eaux d'alimentation de l'écloserie de la Ferme Marine de Douhet (FMD), pour une amélioration de la survie larvaire de la daurade royale (Sparus aurata) ArchiMer
Hussenot, Jerome; Mornet, Francoise; Le Moine, Olivier; Geairon, Philippe; Guesdon, Stephane.
This study aimed to analyse the quality of the sea water flowing into the marine farm of Douhet, a gilthead bream hatchery, from the marsh-seawater reservoir to the entrance of the hatchery. The basin-seawater reservoir is not stratified in the pumping area. As a consequence, the measurements carried out at the surface to the right of the pumping dock give a good evaluation of the quality of the seawater pumped in depth. The high sensitivity of gilthead bream larvae to the water PH during the first two weeks of their larval life, and the values measured in the circuit seem to be an explanatory parameter to the observed mortalities. The water flowing into the hatchery retains, after pre-treatment, a nycthemeral PH variability, with maxima, at the end of the...

La pisciculture marine : un secteur industriel en émergence ArchiMer
Paquotte, Philippe; Harache, Yves.
In a general context of low progression, European aquaculture has been characterized by the development of intensive fish farming. The most notable fact is the recent increase in intensive salmonid farming, with a turnover of almost two million ECU. More recently, the intensive farming of sea bass and sea bream has increased very rapidly in the Mediterranean Basin, although on a more reduced extent. Although research has started as soon as the seventies with a strong public incentive both for salmon, sea bass and sea bream, the development of these different types of aquaculture has not been done at the same pace. Some elements of sectorial dynamics are analysed such as research planning and financing, organization of the production and public policy. For...

Natural abundance of N-15 and C-13 in fish tissues and the use of stable isotopes as dietary protein tracers in rainbow trout and gilthead sea bream ArchiMer
Beltran, M.; Fernandez-borras, J.; Medale, Francoise; Perez-sanchez, J.; Kaushik, Sadasivam; Blasco, J..
For developing efficient diets, two sets of experiments examined whether the use and allocation of dietary protein can be traced by labelling with stable isotopes (N-15 and C-13) in two culture fish (Oncorhynchus mykiss and Sparus aurata). In the first experiment, natural abundance and tissue distribution of these isotopes were determined, by measuring the delta C-13 and delta N-15 values by isotopic ratio mass spectrometry, in fingerlings (14-17 g) adapted to diets differing in the percentage of fish meal replacement by plant protein sources. For both species, delta N-15 and delta C-13 were greater in tissues with higher protein and lower lipid content. Delta N-15 of diets and tissues decreased as replacement increased, suggesting delta N-15 can be used...

Seasonal variation of physical, chemical and sensory characteristics of sea bream (Sparus aurata) reared under intensive conditions in Southern Europe ArchiMer
Cardinal, Mireille; Cornet, Josiane; Donnay-moreno, Claire; Gouygou, Jean-paul; Berge, Jean-pascal; Rocha, E.; Soares, S.; Escorcio, C.; Borges, P.; Valente, L. M. P..
This study describes the variability of important quality traits in gilthead sea bream produced under intensive conditions in Southern Europe and purchased in a French market (Nantes). Chemical, sensory and histological characteristics were performed on 18 samples delivered over a year. All fish presented far lower dioxin and DL-PCBs or heavy metals concentrations than the maximum limit level set by EC Regulation, being totally safe for human consumption. Fat content and nutritional values reflected by n-3 and n-6 polyunsaturated fatty acids (PUFA) levels were parameters with high variability according to the season or the fish farm. Values of n-3 PUFA ranged from 0.9% to 8.6% and those of n-6 PUFA from 9.3% to 16.6%, corresponding to a respective...

The effect of nucleic acids on growth, ureagenesis and nitrogen excretion of gilthead sea bream Sparus aurata juveniles ArchiMer
Oliva Teles, A; Guedes, M; Vachot, Christianne; Kaushik, Sadasivam.
The aim of this trial was to evaluate the effect of dietary nucleic acids on ureagenesis and nitrogen balance in gilthead sea bream juveniles. For that purpose, 5 isonitrogenous (7.25% N) diets were formulated based on fish meal as protein source (FM-control diet) and to partially replace the fish meal nitrogen with two levels of nucleic acids (diets RNA1 and RNA2) or brewers yeast (diets BY1 and BY2). Each diet was fed for 10 weeks, to apparent visual satiety, to triplicate groups of 50 fish each with an average body weight of 12.7 g. Inclusion of nucleic acid N either as brewers yeast or RNA led to significant improvement of feed intake and growth, except for fish fed diet RNA2. There were no differences in final weight between groups fed the yeast-...

Tri d'alevins de loup et de dorade au stade juvénile (0,2 - 12 g) ArchiMer
Lemarie, Gilles; Gasset, Eric.
The authors present the necessary to sort catfish and sea bream fries in order to limit cannibalism, to constitute homogeneous groups. In the same time they studied different sorters (bars sorter, grating sorter and the conception of an experimental sorter) and their effects on the juveniles (behaviour). Introduction: In hatchery, early sorting of Sea Bass or Sea Bream fry after weaning can become necessary for several reasons: a) To obtain homogeneous batches thus simplifying growing management by better controlling: - Specific water flow for precise ranges of size or weight, - Food distribution granularity, - Daily feeding rate. b) To limit cannibalism which can become high when population dispersion is spread out. This dispersion greatly increases...
