“…This causes a negative effect on fish productivity due to the morphological alterations reached at commercialization stage. Finally, the economic value of the final product decreased (Boglione et al;Fernández et al, 2008). This paper describes, for the first time, the development of the vertebral column and caudal skeleton in sabalo larvae under culture conditions as being similar to that described in other teleostean fishes with some peculiarities that differentiate it from other groups (Hernández et al, 2012).…”

“…Under culture conditions previously fixed in this work, a range of 35 to 38 vertebrae was counted, in comparison to that (37 and 38 vertebrae) reported by Roberts (1973) in Prochilodus specimens. According to Boglione et al (2001), the meristic features present high variability in hatcheries when compared to those in wild groups. This difference can be attributed to the high variability of osteological development stages that presented fish as result of the interaction between genetic and environmental factors (Boglione et al;Cardoso et al, 2004).…”

SUMMARY:For successful fish larviculture thorough studies describing the development of fish in different morphological aspects are required, as they are crucial for larval survival and growth. The present study described in Prochilodus lineatus larvae the osteological development of the vertebral column and caudal skeleton 30 days after hatching (dah). Larvae were obtained by artificial induction of adults. The beginning of formation of the spine occurs between 10 to 12 dah (8.3 mm standard length, SL) simultaneously to the first neural and hemal processes and the pre-caudal vertebral bodies. The ossification of the vertebral column occurred in craniocaudal direction and was completed at 28 dah (22.6 mm SL). The development of the caudal skeleton elements started between 6 and 8 dah with the formation of the hypurals (H), the parahipural (PH) and the primary and secondary caudal rays. H 1 to H 3 were formed as cartilaginous primordia on the ventral side of the distal portion of the notochord, while the PH and H 4 to H 6 were formed subsequently. The first rays of the caudal fin were observed in correspondence with the formation of H 2 and H 3, while complete formation of the caudal fin was observed at 28 dah. The epurals, three in number, were evident as cartilaginous elements located both dorsal and distal in the notochord. Central ural complex (CUC) was formed by the fusion of three structures, the center preural 1 and urals 1 and 2. Development of the vertebral column and the caudal skeleton in P. lineatus larvae showed similar patterns to those described for other teleosts.

“…Differences occur in many cases. In addition, several studies suggest that frequency of abnormalities tends to be higher in hatchery-reared organisms than in wild individuals (Ellis et al, 1997;Boglione et al, 2000;Mana and Kawamura, 2002). Some of these differences and abnormalities potentially lead to survivorship advantages or disadvantages relative to wild organisms, while others may not.…”

“…VCD exhibits major deviations in the column curvature (Gavaia et al, 2001;Silverstone & Hammell, 2002;Lewis et al, 2004;Sullivan et al, 2007) and morphological anomalies in the vertebral bodies (Witten et al, 2006;Fjelldal et al, 2007), lower weight, lower survival, faulty swimming, decreased body length and increased susceptibility to other stressors and diseases (Boglione et al, 2001., Gjerde et al) VCD was first reported in 1981 (McKay & Gjerde, 1986), and associated to economic loss in the mid '90s. (Vagsholm & Djupvik, 1998), but its etiopathogeny is not yet understood (Fjelldal et al).…”

CASTRO, S. R.; BUSTOS OBREGON, E. & ROJAS, R. M. Vertebral column deformity and hypoxia in SUMMARY:Vertebral Column Deformity (VCD) is a common pathology in Chilean salmon farms, lowering the quality and commercialization of the product. Hypoxia has been related to other musculoskeletal deformities, but not to VCD. This work analyzes the morphology of the vertebral column of Salmo salar alevins, cultured under hypoxic conditions (60% O2 saturation in the water tanks) for different time periods after hatching (2, 4, 6 and 8 days). They are compared with their normoxic controls (100% O2 saturation). Using histological (H/E), and morphometric techniques, it was found that the time of exposure to hypoxia is inversely proportional to the body length, notochordal diameter and thickness of its sheath. The organic response to hypoxia was quantified by immunohistochemistry for HIF-1a as the sensor of hypoxia. Its expression increased significantly (p<0.05) in the experimental groups that exhibit VCD. Although etiology for VCD is probably multifactorial, this study allows for the conclusion that hypoxia by itself, produces VCD.
