“…The incidence of all deformity types was recorded. The classification of cranial malformation was performed according to [6,9]. The types of deformities were as follows: shortened lower jaw, shortened upper jaw, elongated lower jaw, open mouth, and short operculum.…”

“…Among the many different types of malformation described, the most severe are jaw deformities, which are present during the larval phase of cultured fishes [4]. Jaw deformities are manifested in several forms such as shortening, twisting and bending of the upper or lower jaw among other phenotypes [5][6][7][8][9].…”

“…However, craniofacial development begins at early stages of embryonic development when a cell population named neural crest is induced and differentiates into craniofacial cartilage which develop later into the pharyngeal bones and skull [29]. S. lalandi deformed larvae have been observed before first feeding (4 dph), suggesting that both nutritional factors present in the embryonic yolk and broodstock diets needs to be studied as possible causative factors of deformities [6,9].…”

Jaw malformations imply an important problem during the commercial production of Seriola lalandi larvae and juvenile fish in Chile and New Zealand. Since the rate of malformations in other fish species has been associated with the content of long-chain PUFA (LC-PUFA) in neutral lipids of the diet, the relationship between body LC-PUFA and the rate of malformations, together with a transcriptomic analysis of genes related to the metabolism and transport of lipids in commercially produced S. lalandi larvae have been investigated in the present work. A total of 10 batches of S. lalandi larvae were obtained and cultured at about 22 °C following the protocols of a Chilean commercial hatchery during the spawning season. There were three larval batches that were collected in August (austral winter), three batches that were obtained in October (spring), and finally four spawning events that were obtained in December-January (spring-summer). The rate and type of jaw malformations, the profile of long-chain PUFA (LC-PUFA) of total lipids during larval culture, and the distribution of LC-PUFA were analyzed. Additionally, a transcriptome analysis related to lipid metabolism in 40-day-old larvae was performed. As a result, a decrease in the rate of malformations was recorded from August to December. DHA showed a steep decrease between days 1 and 10 of culture, probably due to the consumption of yolk sac lipids, but a higher proportional change was noted in larvae that hatched during August. The DHA content in polar lipids (PL) and neutral lipids (NL) of 40-day-old larvae increased from August to December, so that the abundance of DHA was higher in PL in larvae that hatched in December, but it was higher in NL in those larvae that hatched in October. In conclusion, the rate of jaw malformations was associated with the rapid decline in DHA during early larval life and the highest abundance of DHA in neutral lipids at the end of the larval life.

“…For fish in the wild, skeletal anomalies, which can occur at any stage of the fish life cycle, can cause complications, for example in protecting their territories (Sato 2006;Majeed et al 2018), competing for a mate (Sato 2006), and reduction in fisheries production (Noble et al 2012). In aquaculture facilities, such deformities may affect animals by reducing their growth rates (Hansen et al 2010), impairing their feeding ability (López-Olmeda et al 2012;Okamura et al 2018), increasing the risk of infection (Janakiram et al 2018) and increasing mortality rates (Jara et al 2017). Furthermore, these undesirable effects of skeletal aberrations will result in economic decline of fish farms (Boglione 2013;Yıldırım et al 2014).…”

In this study, skeletal anomalies such as vertebral centra deformation, lordosis (ventral curvature), and consecutive repetition of lordosis and kyphosis were examined in specimens of Barbus xanthos (Güçlü, Kalaycı, Küçük & Turan, 2020) collected from the Dalaman River, southwestern Turkey. Abnormalities of the vertebral column were observed in both thoracic and caudal vertebrae. Cases of lordosis and consecutive repetition of lordosis and kyphosis showed varying degrees of severity. Specimens with consecutive repetition of lordosis showed the most acute deformities among the cases studied, as they revealed complicated incidences of skeletal anomalies. None of the cases were fatal as they occurred in adult individuals. This study discusses the possible causes of such deformities and the usefulness of this type of study in environmental monitoring.

“…In wild fish, skeletal deformities that occur in any life stage of fish can cause them difficulties such as defending their territory (Sato, 2006;Majeed et al, 2018), competing for a mate (Sato, 2006), and decreasing production performance (Noble et al, 2012). In farmed fish, these injuries can affect the organism by reducing growth (Hansen et al, 2010), limiting their feeding ability (López-Olmeda et al, 2012;Okamura et al, 2018), increasing the infection (Janakiram et al, 2018) and mortality rate (Jara et al, 2017). Moreover, these negative effects of the skeletal deformities inevitably cause reasonable economic loss in the fish farms (Boglione, 2013a;Yıldırım et al, 2014).…”

Skeletal deformities are relatively well described in both cultured and wild fish. These diseases are observed in many fish species and occur due to environmental and genetic factors. It negatively affects the biological performance and commercial value of fish. For this reason, this study attempts to quantify and identify kyphosis in the natural populations of Barbus pergamonensis Karaman, 1971 collected from Dalaman Stream (Gölhisar/Burdur) and tends to find a possible relationship between these anomalies and several types of pollutants present in the environment. The current study found that the environmental pollutants may represent a potential risk to induce kyphosis in the natural populations of B. pergamonensis.
