“…Survival rates of the spotted rose snapper larvae during the rearing period were improved in this study, compared to those of previous trials conducted in 600‐L cylindrical fiberglass tanks (Garcia‐Ortega et al 2005; Abdo‐de la Parra et al 2010), and the average survival rate achieved for this species in Costa Rica (Boza‐Abarca et al 2008; Herrera‐Ulloa et al 2010). High mortality occurred during two critical periods: at the start of the exogenous feeding phase, as reported for spotted rose snapper by Boza‐Abarca et al (2008) and for other snapper species (Lim et al 1985; Emata et al 1994; Duray et al 1996; Tucker 1998); and during metamorphosis, which in itself is a stressor in fish larvae (Kraul et al 1993).…”

“…These trials resulted in the production of only a few juveniles (Alvarez‐Lajonchère et al 2010). In 2005, a captive broodstock population was established at the CIAD Mazatlan facility, and the first larvae obtained through hormone induction (Ibarra‐Castro and Alvarez‐Lajonchère 2009) enabled the conduction of small‐scale experiments to improve larviculture techniques (Abdo‐de la Parra et al 2010). Afterward, natural spawning of high‐quality eggs from the captive broodstock (Ibarra‐Castro and Alvarez‐Lajonchère 2011) enabled scaling‐up using experimental larval rearing technology (Abdo‐de la Parra et al 2010) to a new pilot‐scale plant (Alvarez‐Lajonchère et al 2007).…”

The scale‐up of spotted rose snapper, Lutjanus guttatus, larval rearing is described. Fertilized eggs (480,000) were obtained from a 1‐d harvest of a natural spawning captive broodstock acclimatized for 1 yr and 6 mo in two fiberglass tanks (18 m3). Fourteen hours after spawning, 89.6% of the collected eggs were floating, of which 96.2% were transparent with live embryos. Incubation at 25–26 C lasted 21 h, with 90.2 ± 2.1% hatching percentage of normal larvae. The percentage of viable larvae at 48 h after hatching was 79.7 ± 1.9%. Initial stocking density was 10.4 ± 1.0 larvae/L 2 days after hatching (d.p.h.). A total of 22,600 juveniles (1256 ± 170 juveniles/m3) were harvested from six 3‐m3 cylindrical fiberglass tanks. Average survival was 12.1 ± 1.1%. Final mean length and weight were 5.5 ± 0.05 cm and 2.24 ± 0.04 g, respectively. Growth expressed in total length was TL = 2.1476e0.0543t (R2 = 0.9911). Final mean biomass and condition factor were 2.8 kg/m3, 12.3% and 1.346. General length‐weight ratio was W = 0.05460 LT2.2306.

Osteological development of the vertebral column and caudal complex of Lutjanus guttatus (Perciformes: Lutjanidae) larvae under rearing conditions. The spotted rose snapper (Lutjanus guttatus) is an important commercial species in Mexico with good culture potential. The osteological study at early stages in this species is an important tool to confirm normal bone structure and for the detection of malformations that may occur during early development. This study was carried out in order to evaluate and describe the normal osteological development of the vertebral column and caudal complex of this species grown under controlled conditions. For this, a total of 540 larvae of L. guttatus, between 2.1 and 17.5mm of total length (TL), were cultured during 36 days; culture conditions were 28ºC, 5.74mg/L oxygen and 32.2ups salinity with standard feeding rates. To detect growth changes, a sample of 15 organisms was daily taken from day one until day 36 of post-hatch (DPH). Samples were processed following standard techniques of clearing, and cartilage (alcian blue) and bone staining (alizarin red). Results showed that the vertebral column is composed of ten vertebrae in the abdominal region, and 14 vertebrae including the urostyle in the caudal region. The development of the axial skeleton starts with the neural arches and haemal arches at 3.8mm TL. Caudal elements such as the hypurals and parahypural began to develop at 4.1mm TL. Pre-flexion and flexion of the notochord and the formation of all hypurals were observed between 5.3 and 5.8mm TL. Ossification of the vertebrae in the abdominal region and in some neural arches initiated at 9.5mm TL. In the caudal region, all the neural and haemal arches ossified at 10.2mm TL. All the abdominal vertebrae and their respective neural arches and parapophyses ossified at 11.2mm TL, while the elements of the caudal complex that ossified were the hypurals, parahypurals and modified haemal spines. All caudal fin rays, 12 neural spines and 3 haemal arches were ossified by 15.5mm. The complete ossification process of this specie under laboratory culture conditions was observed when larvae reached 17.3mm TL on 36 DPH. Detailed analysis of the osteological structures will allow a reference description to evaluate and detect malformations that may occur during the larval culture of the spotted rose snapper. Rev. Biol. Trop. 63 (1): 155-164. Epub 2015 March 01.

In this study, the developmental expression pattern of myostatin (mstn) in the spotted rose snapper Lutjanus guttatus under culture conditions is presented. The full coding sequence of mstn from L. guttatus was isolated from muscle tissue, obtaining 1134 nucleotides which encode a peptide of 377 amino acids. The phylogenetic analysis indicated that this sequence corresponds to mstn-1. mstn expression was detected in embryonic stages, and maintained at low levels until 28 days post-hatch, when it showed a significant increase, coinciding with the onset of metamorphosis. After that, expression was fluctuating, coinciding probably with periods of rapid and slow muscle growth or individual growth rates. mstn expression was also analysed by body mass with higher levels detected in smaller animals, irrespective of age. mstn was also expressed in other tissues from L. guttatus, presenting higher levels in brain, eye and gill. In brain for instance, two variants of mstn were isolated, both coding sequences were identical to muscle, except that one of them contained a 75 nucleotide deletion in exon 1, maintaining the reading frame but deleting two conserved cysteine residues. Phylogenetic analysis indicated that this brain variant was also mstn-1. The function of this variant is not clear and needs further investigation. These results indicate that mstn-1 participates in different physiological processes other than muscle growth in fishes.
