“…Almost all research and commercial culture activities are based on wild-caught juveniles or eggs produced from hormoneinduced mature breeders obtained from the wild (Tachihara et al 1993;Jover et al 1999;Nakada 2000;Lazzari et al 2000;Mazzola et al 2000;Pastor et al 2000). However, successful maturation and spawning has been achieved more recently with the use of gonadotropin-releasing hormone agonist (GnRHa) loaded into controlled-release devices (Mylonas et al 2004). In addition, larval rearing was successfully achieved by mesocosm technology (Papandroulakis et al 2005).…”

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 for a period of 30 days to a diet with a 40% moisture content, were fed on commercial pellets containing three different levels of dietary moisture (7, 20 and 40%, respectively) for 126 days. We found that fish needed a month to adapt to the 7%-and 20%-moisture diets and that moisture content of the diet had a significant effect on fish growth in terms of increasing feed consumption and lowering feed conversion ratio. The group fed on the 20%-moisture diet not only compensated for the initial adaptation period but presented the higher growth rate and best feed conversion ratio. In the second experiment, all groups of experiment 1 were fed the same commercial diet with a 7% moisture content for 72 days. The group that had been previously fed on the 20%-moisture diet showed the best growth performance. The implication of the above results for the weaning of greater amberjack to dry diets is discussed in terms of the digestion process and physiology.

“…Bone description, followed the terminology suggested by different authors [41][42][43], and their abbreviations, and are illustrated in the Table 1. The angles of the spine from the surface to internal bone layers (Figures 2A and 2B), whereas in the haemal (with Hs) and caudal region (Ns and Hs modified to support caudal fin complex) the mineralization pattern proceeds in both directions dorsal and ventrally (Ce [11][12][13][14][15][16][17][18][19][20][21] and Ce 22-23 respectively), joining in the middle of the centra ( Figure 2C). Exceptionally, in Ce 9 and Ce 10 , the mineralization of the vertebral bodies differed from other vertebral structures of the prehaemal region, proceeding dorsally first and ventrally later on.…”

“…In S. aurata [30] and D. sargus [47], two centra mineral deposition models occur the first one takes place in a D-V direction from the Ce 1 to Ce 21 and the second one in a V-D direction in Ce 22 and Ce 23 . In S. rivoliana, the mineralization expands in a D-V direction from Ce 1 to Ce 23 , following the same pattern as S. dumerili between the Ce 1 -Ce 19 [28].…”

“…Even though S. rivoliana is commercially produced [3], studies about its biology are scarce and only few reports on larval rearing have been conducted in Ecuador [4][5][6], Hawaii [7] and more recently in the Canary Islands [8]. In contrast, numerous studies of the genus Seriola have been published related to the feeding requirements and nutrition [9][10][11][12][13][14][15][16][17], reproduction biology [2,[18][19][20][21] and culture needs [8,[22][23][24][25][26].…”

Bone and fins development in Seriola rivoliana were studied from cleared and stained specimens from 3 to 33 days after hatching. The vertebral column began to mineralize in the neural arches at 4.40 ± 0.14 mm Standard Length (SL), continued with the haemal arches and centrums following a cranial-caudal direction. Mineralization of the caudal fin structures started with the caudal rays by 5.12 ± 0.11 mm SL, at the same time that the notochord flexion occurs. The first dorsal and anal fin structures were the hard spines (S), and lepidotrichium (R) by 8.01 ± 0.26 mm SL. The metamorphosis was completed by 11.82 ± 0.4 mm SL. Finally, the fin supports (pterygiophores) and the caudal fins were completely mineralized by 16.1 ± 0.89 mm SL. In addition, the meristic data of 23 structures were provided. Results from the present study might be used as a practical guide for future studies on this field with S. rivoliana or in related species.

“…Actualmente, la tendencia más utilizada es la administración de hormonas liberadoras de gonadotropinas (GnRH) y sus análogos potenciados (Marino et al, 2003;Mylonas et al, 2004;Vermeirssen et al, 2004;Arabaci et al, 2004a;Levavi-Sivan et al, 2004;Dorafshan & Heyrati, 2006;Ronyai, 2007), ya que actúan al más alto nivel del eje hipotálamo-pituitaria-gónada, promoviendo un adecuado balance de la cascada hormonal reproductiva y desencadenando el desove y espermiación .…”
