“…In artificial juveniles, the number of total vertebrae was fewer than that in wild fish (Hosoya & Kawamura, 1997). More than 13% reared flounder had deformed vertebrae, and no deformed vertebra was found in the wild ones (Lv et al, 2015). In this study, the rate of skeletal abnormalities in diploids was 33.3%, and the triploids showed a significantly higher incidence (60.0%, p < 0.05).…”

Growth, skeletal structure and muscle composition of cold-shock-induced triploid olive flounder Paralichthys olivaceus were investigated. The average values of total length and total weight of triploids were higher than those of diploids from 5 to 11 months posthatch (mph). The growth difference disappeared after 11 mph. The skeletal structure of flounder at 11 mph was observed by X-ray imaging method. There are four kinds of vertebral deformity including vertebrae fusion, one-sided compression, two-sided compression and vertically shifted. The trunk region (V8-18) and tailing end of the vertebral column were the predominant locations of deformity. In general, the frequencies of vertebral deformities in triploids (60.0%) were higher than those in diploids (33.3%, p < 0.05). Both the number of fish with deformed vertebrae and the average frequencies of deformed vertebrae in triploids were significantly higher than those in diploids (p < 0.05). The muscle tissues of diploid and triploid flounder at 11 mph contain the same types of fatty acid and free amino acid profiles. The number of fatty acids with significant higher contents in diploids and triploids was one and ten, respectively (p < 0.05). The contents of free amino acids showed no difference between triploid and diploid fish.

“…Unfavourable temperature conditions, inflammation and damage or rupture to the intervertebral ligaments resulting from rearing conditions were suggested causes of vertebral deformities in reared Japanese flounder (LÜ et al ., 2015). Fish exposed to high temperatures show not only rapid growth performance but also a significantly incidence of anomalies in vertebral column when compared with other fish at low temperatures ( Ytteborg et al, 2010 ) .…”

Skeletal deformities in fish are abnormal transformations of normal bony and/or cartilaginous structures into abnormal skeletal structures that are histologically and anatomically different from their normal prototype. Such deformities are diverse in their location, morphology and impact. The three main topographic regions of a fish (head, trunk and tail) could be affected by several types of deformities with various degrees of severity depending on the cause, age and histology of the affected tissue, regardless of whether it is bony or cartilaginous. The degree of skeletal deformity could impact physiological processes, including swimming, reproduction, growth, resistance to diseases and susceptibility to predation, as well as being the direct or indirect cause of low body weight gain or even death in young fish. Skeletal deformities are commonly recorded from wild and cultured fish, with high incidence in fish hatcheries. Skeletal deformities are responsible for considerable economic damage to the sector of aquaculture by making fish unsightly and affected fish consequently remain unsold. Such deformities are also proposed as biological indicators of aquatic environmental pollution and defaults in aquaculture management. Several diagnostic techniques, such as radiography, ultrasonography and magnetic resonance imaging, have been used for detecting and defining skeletal deformities in fish. Here, the present review summarizes the incidence, classification, aetiological factors, diagnostic procedures and prevention of the most common skeletal deformities in fish.

“…Skeletal and opercular deformities, often reported in fish reared in intensive systems, can seriously affect efficient culture (Koumoundouros, Oran, Divanach, Stefanakis, & Kentouri, ; Policar et al., ), negatively affecting fish physiology and welfare, growth performance, and quality and value of product (Fjelldal et al., ). The aetiology, frequency of occurrence and biological significance of deformities vary among fish species (Chin, Loh, Hong, & Gibson‐Kueh, ; Georgakopoulou, Katharios, Divanach, & Koumoundouros, ; Lü et al., ; Nguyen, Whatmore, Miller, & Knibb, ). The aim of this study was to record the frequency of vertebral, opercular and fin deformities in intensively reared peled Coregonus peled (Gmelin 1879).…”

“…The consequences of vertebral deformities for body shape depended on position along the vertebral column (Figure ). Frequency of spinal deformities varies among cultured fish species, with reports ranging from 7.7% in barramundi Lates calcarifer to 19% in Atlantic salmon (Fraser, Anderson, & de Nys, ; Fraser, Hansen, Fleming, & Fjelldal, ; Lü et al., ).…”
