Abstract:
... Zeuxapta seriolae (Monogenea: Heteraxinidae) infection was associated with important mortalities of amberjacks (Seriola dumerili) reared in tanks in the experimental facilities of the Spanish Institute of Oceanography (Western Mediterranean) during the period 1998-2000. Fish infested by this parasite presented characteristics similar to those described for Seriola quinqueradiata parasitized by Het ...
... The objective of the current study was to examine the possibility of maturing Mediterranean greater amberjack (Seriola dumerili) in culture at two different facilities in Greece and inducing spawning using gonadotropin releasing-hormone agonist (GnRHa) implants. Males in both stocks (n=8) were in spermiating condition in mid June, though sperm motility was low ranging between 5% and 30%, while mot ...

Abstract:
... Species diversification is considered a major approach for the sustainable development of aquaculture. The greater amberjack (Seriola dumerili) has particular characteristics-advantages making it an appropriate candidate: high growth rate, large size, and established worldwide market. In the present study, the mesocosm method for larval rearing was applied, since it has been shown to be effective ...

Abstract:
... The availability of defatted soybean meal as a substitute for fish meal was evaluated in juvenile (450 g on average) yellowtail fed diets containing several levels of soybean meal (from 20 to 50%). After 153 days, liveweight averages were 980, 925, 795 and 670 g for fish fed diets in which fish meal was partially substituted with 20, 30, 40 and 50% soybean meal, and feed conversion ratios were 2.7 ...

Abstract:
... This paper describes results on sexual maturation and natural spawning of Seriola dumerili kept in captivity on Tenerife (Canary Islands). Wild fish captured at an average weight of 8 kg, spawned naturally and reaching an average weight of 25 kg, after 6 years in captivity in 500 m3 raceway tanks, under natural conditions of light and temperature and fed on low-value fish. Spawning took place betw ...

Abstract:
... A study was conducted to determine optimum dietary digestible protein (DP) and digestible energy (DE) levels and DP DE⁻¹ ratio for growth of greater amberjack Seriola dumerili fingerlings. A 3 x 3 factorial design with duplication was used in this study. Nine experimental diets were formulated to contain three levels of crude protein (CP; 420, 470 and 530 g kg⁻¹) and three levels of crude lipid (C ...

Abstract:
... Eighteen nuclear-encoded microsatellites from a genomic DNA library of greater amberjack, Seriola dumerili, were isolated and characterized. The microsatellites include 13 perfect (five tetranucleotide and eight trinucleotide) and five imperfect (three tetranucleotide, one trinucleotide and one combination dinucleotide/trinucleotide) repeat motifs. The number of alleles at the 18 microsatellites a ...
... A study on fish assemblage associated with fish aggregating devices (FADs) in Sicily was carried out between January 2000 and January 2001. With a fortnightly periodicity, 156 experimental hauls were carried out by means of a purse seine in a FAD-containing marine section banned to commercial fishing. A total of 14 229 fish specimens belonging to six families and 10 species was found. These specie ...
... FADs are fish aggregating devices applied worldwide over the centuries to increase fish catch. However, the utilisation of such floating devices can influence dispersion patterns of some fish species. At present it is still not clear if FADs play a role in the shoreward migrations of juvenile fish of reef associated species, such as the greater amberjack Seriola dumerili. In this study, we hypothe ...
... Thirteen nuclear-encoded dinucleotide microsatellites were characterized from a genomic DNA library of greater amberjack, Seriola dumerili. The microsatellites include 12 perfect-repeat motifs and one imperfect-repeat motif. The number of alleles at the 13 microsatellites among a sample of 29 fish ranged from 3 to 25; gene diversity (expected heterozygosity) ranged from 0.296 to 0.948, while obser ...
... Yellowtails weighing 490 g were fed five experimental diets with different protein/energy ratios, 24.6, 26.9, 28.9, 31.8 and 35.8 g MJ⁻¹, for 152 days. The energy content was similar in all the diets and the protein and lipid levels were 40/26, 45/26, 50/18, 50/26 and 55/18 %CP/%CL respectively. The final weight and SGR were lower in fish fed diets with a lower PD/ED ratio (24.6 and 26.9 g MJ⁻¹), ...
... The phenotypic and genetic characterizations of 58 isolates of the fish pathogen Nocardia seriolae, from amberjack, Seriolae dumerili, yellowtail, Seriola quinqueradiata, Japanese flounder, Paralichthys olivaceus, and chub mackerel, Scomber japonicus, in Japan from 1970-2005, were examined to investigate the epidemiological relationship between isolates. The phenotypic and genetic characterization ...
... To improve the nutritional quality of live foods and dry feeds ordinarily used for the seed production of amberjack Seriola dumerili, the nutrient contents of rotifers, Artemia nauplii and commercial feeds used in two larval production stations were evaluated. For comparison of the nutrient contents, artificially produced larvae, wild-caught juveniles and wild zooplankton samples were also analyze ...
... This study investigated: 1) susceptibility differences to infection by Neobenedenia girellae (Capsalidae) between amberjack Seriola dumerili (Carangidae), yellowtail S. quinqueradiata and Japanese flounder Paralichthys olivaceus (Paralichthyidae); 2) growth and egg production of N. girellae on each fish species; 3) acquired protection of each fish species against this parasite. The number of N. gi ...
... The weaning of greater amberjack (Seriola dumerilii Risso 1810) to a dry diet was studied in two consecutive experiments. The experimental fish were hatchery-produced and grown to their initial size on a soft pellet containing 50% trash fish and 50% commercial dry pellet. In the first experiment, three homogenous groups of greater amberjacks (n = 153, mean weight: 374 ± 43 g), initially adapted fo ...

Abstract:
... High mortality following transfer of early juvenile Pacific bluefin tuna (PBT) aged around 30 days post hatching (about 5 cm total length) from hatchery tanks to sea net cage, particularly during the first few days, is a major problem inhibiting development of large-scale culture operations. Survival rate of the fish after stocking from land tank to a small sea cage was dropped to about 50% or les ...

Abstract:
... This study presents a description of the developmental stages of a new sanguinicolid disease agent (Paradeontacylix ibericus) of cultured Seriola dumerili (greater amberjack) in the Mediterranean, and investigates parasite habitat selection in the definitive host and the development of sanguinicolidosis in experimental, inshore cultures of S. dumerili. Two experimental surveys were carried out usi ...
... This study was designed to investigate: 1) the distribution of Neobenedenia girellae (Capsalidae) on host amberjack Seriola dumerili (Carangidae) and growth of the parasite during infection; 2) the influence of different N. girellae exposure levels on S. dumerili growth; and 3) the histopathological skin changes of S. dumerili infected with N. girellae at the different parasite densities. N. girel ...
