. Hematological, serum biochemical, histological, and scanning electron microscopic studies were performed on normal and infected hosts to study the effects caused by the nematode. Results:The mean values of red blood corpuscle [RBC] ) were significantly higher (P<0.01) than those in noninfected fish. Significant differences were also observed in total protein and glucose levels between the infected and noninfected fish. Histological and scanning electron microscopic studies of the host tissues revealed a series of pathological changes and mechanical damage. Conclusion: It can be concluded that Eustrongylides sp. has a significant impact on its host and thus the parameters outlined in the present paper may be employed as tools in monitoring the health status of fish in culture practices.

Konak dokuların histolojik ve taramalı elektron mikroskobu çalışmaları bir seri mekanik zarar ve patolojik değişiklikleri açığa çıkarmıştır. Sonuç: Bu çalışmadan Eustrongylides sp.'nin konağı üzerine anlamlı etkiye sahip olduğu sonucu çıkarılabilir ve, bu bulgular, yetiştiriciliği yapılan balıkların sağlık durumlarını izlemede araç olarak kullanılabilir.

“…In the present study, the lowest glucose or lactate concentrations in these months are associated with changes in hepatic parameters related to glucose or lactic acid metabolism (see below), and could indicate a reduction in the hepatic capacity to produce these metabolites, focusing these resources into somatic growth (Foster andMoon 1991, Sala-Rabanal et al 2003). In addition, in spring (April) plasmatic levels of proteins, triglycerides (TAG) and liver glycogen increased, while HSI decreased (probably due to hepatic TAG mobilization), followed by a depletion in plasma glucose, proteins and TAG as well as liver glycogen (May-July), which may also be related to an acceleration in the growth of the animals (Gallardo et al 2003, Ibarz et al 2005, Vargas-Chacoff et al 2009a. In winter (November), metabolic pathways have to confront a critical situation due to lower temperatures (Somero 2004).…”

Summary:Metabolic modifications associated with natural environmental conditions were assessed in the meagre Argyrosomus regius cultured in earthen ponds under natural photoperiod and temperature. Juvenile specimens (90-100 g initial weight) were sampled (plasma, liver and muscle) every two months for 18 months (between December 2004 and May 2006). Specimens showed seasonal variations in growth rate, with the highest values in spring and summer. Plasmatic, hepatic and muscular metabolite levels and hepatic and muscular metabolic enzymes also showed significant variations throughout the year. Enzymatic activity related to carbohydrate metabolism in the liver (HK, FBPase and G6PDH) showed great modifications in summer, increasing glycogenogenic pathways, while amino acid metabolism (GDH and GOT activity) was enhanced in spring and summer. However lipid-related (G3PDH activity) metabolic enzymes did not show a clear seasonal pattern. In muscle, enzymatic activity related to amino acid, lipid and lactate metabolism (LDH-O activity), but not carbohydrate metabolism, showed seasonal changes in parallel with changes in growth rate. Thus A. regius specimens showed a trend to grow in summer months and mobilize their energy reserves in winter. Differences in the hepatic level were observed between the first and the second year of the study, suggesting the possible existence of metabolic changes related to specimen age or size. Our results indicate that growth and metabolic responses in A. regius are environmentally dependent and that this species is a very good candidate for diversification in aquaculture.Keywords: Argyrosomus regius; energy; growth; metabolic parameters; ponds; seasons. Crecimiento y cambios metabólicos anuales en corvina Argyrosomus regius cultivada en esterosResumen: Modificaciones metabólicas asociadas a condiciones ambientales temporales fueron evaluadas en la corvina Argyrosomus regius, cultivadas en esteros con fotoperiodo y temperatura natural. Ejemplares juveniles (90-100 g de peso inicial) fueron muestreados (plasma, hígado y músculo) cada dos meses durante 18 meses (entre diciembre de 2004 y mayo de 2006). Las muestras mostraron variaciones estacionales en la tasa de crecimiento, con valores más altos durante la primavera y el verano. Niveles de metabolitos plasmáticos, hepáticos y musculares, así como las actividades de enzimas metabólicas hepáticas y musculares también presentaron variaciones significativas a lo largo del año. La actividad enzimática relacionada con el metabolismo de carbohidratos en el hígado (HK, FBPasa y G6PDH) mostró altas modificaciones en el verano, el aumento de las vías glucogenogénicas, mientras el metabolismo de aminoácidos (actividades de GDH y GOT) se incrementó en temporadas de primavera y verano. Sin embargo la actividad de G3PDH (enzima metabólica relacionada con los lípidos) no mostró un claro patrón estacional. En el músculo, la actividad enzimática respecto a los aminoácidos, lípidos y el metabolismo del lactato (LDH-O) presentó cambios estacionales en paral...

“…Because of its poor tolerance of low temperatures, Sparus aurata suffers from a 'winter syndrome', with a threshold temperature at 12°C, that causes a cessation of feeding, stress, and lethargy (Gallardo et al 2003). This syndrome is consistent with S. aurata overwintering in the sea (Audouin 1962, Ibarz et al 2007, as water temperature in the Mediterranean never falls under this critical value, unlike in the lagoons (IFREMER 2008(IFREMER , 2009).…”

Precise knowledge of lifetime migrations is vital in exploited fish species, since all essential habitats must be protected to maintain sustainable stock levels. The present study used multi-element otolith fingerprints of the gilthead sea bream Sparus aurata (L.) to discriminate its main juvenile and adult habitats in the Languedoc-Roussillon region (Gulf of Lions, northwest Mediterranean) and infer the lifetime migrations of 12 individuals from the area (11 from the present day and 1 from the Roman era). This allowed for the first time the identification of key habitats for the successful completion of the species' life cycle in the Gulf of Lions, and the connectivity between them. Our results revealed that lagoon use by S. aurata is probably ancient (> 2500 yr) and confirmed its current commonness. Yet, although most observed migration patterns were in accordance with the migratory behavior previously described for the species, strong inter-individual variations and new patterns in habitat use were detected. At the juvenile stage, a preference for shallow lagoons with low salinities was evidenced. Nevertheless, the first year of life can also be successfully completed in marine conditions. At the adult stage, lagoon use was shown to occur until at least age 4 yr, with periods of lagoon residency of up to 11 mo in a year, often including winter months. Because overwintering in the lagoons was previously thought to be impossible for S. aurata due to low temperatures, this finding has important implications for future stock management, especially since the species breeds in winter.
