“…This size-related effect may be explained by difference in mouth structure and dentition pattern with seabream age; the anterior elongated teeth of larger individuals (140 and 200 mm TL) likely allow them to better hold or grasp hard prey (Elgendy et al 2016), including bivalves, thus ac counting for the fish's trophic shift with increasing size (Tancioni et al 2003). In contrast to smaller sea bream, the dentition of larger sea bream is probably better adapted to feed on mussels and oysters with their round and flattened posterior teeth able to crush shells, as described in Berkovitz & Shellis (2017). These results corroborate observations by Šegvić-Bubić et al (2011), who noted a high abundance of large (280 to 480 mm, 304 to 1485 g) gilthead seabream in a mussel farm in Marina Bay, central Adriatic Sea.…”

Bivalve predation by seabream has been observed worldwide and is a major concern for bivalve farmers. Farmed bivalve-seabream interactions must be better understood to ensure the sustainability of bivalve aquaculture. The objectives of this study were to characterize gilthead seabream Sparus aurata presence in a bivalve farm in Prevost Lagoon (Mediterranean Sea) using acoustic telemetry and to evaluate monthly losses of mussels Mytilus galloprovincialis and oysters Crassostrea gigas due to seabream predation over an 18 mo period inside the farm and at an unprotected experimental platform. Large (281 to 499 mm TL) seabream were more commonly detected in the bivalve farm than were small (200 to 280 mm TL) seabream. In contrast to small seabream, 90% of large seabream returned to and spent extended periods in the study area the following year, suggesting inter-annual site fidelity for large fish that used the bivalve farm as a feeding site. Signs of predation were observed on mussels and oysters throughout the year at the unprotected experimental platform. Farmers noted losses in the farm from April to September. Maximal losses (90 to 100%) were observed post-oyster ‘sticking’ and mussel socking. Despite the deployment of nets as mechanical protection to reduce predation, oyster losses represented 28% of the annual value of oysters sold while mussel losses were estimated at ca. 1%. These results suggest that bivalves must be protected by nets throughout the year to avoid predation, particularly post-handling. A collaboration between shellfish farmers and fishermen could be a sustainable solution for bivalve farming, by regularly fishing for seabream in farms, between tables and inside protective nets.

“…The present study showed that the urostyle ossifies as a single structure, placing C. dimerus in the first category. Regarding the development of the hypuralia, three variations of fusion have been described: five hypurals develop separately, but hypurals 1–2 fuse during ontogeny to form the lower hypural plate, and hypurals 3–5 show different degrees of fusion in some Atherinomorpha, clinids, mugilids, and pomacentrids; the lower and upper plates develop without a separate hypural precursor in blennids; and none of the five hypurals fuse during development in cichlids (Berkovitz & Shellis, 2017; Thieme et al, 2021; Woltering et al, 2018). Similar to other cichlids, C. dimerus did not evidence hypural fusion at least for the age and size range examined in the current study.…”

“…At this stage, mainly the bones from the jaws, the ceratobranchial arches with their gill rakers and the pharyngobranchial and ceratobranchial toothplates, and the opercular complex evidenced some degree of ossification. Particularly, in cichlids, it has been proposed that the pharyngeal jaws are involved in food processing, whereas the oral jaws are more involved in food capture (Berkovitz & Shellis, 2017; Conith & Albertson, 2021). Thus, in resemblance to other teleost fishes, the first structures to start ossification in the cranial region belong to the splanchnocranium, whereas most of the bones from the neurocranium tend to ossify later and more slowly (Vandewalle et al, 1992, 1995; Wagemans & Vandewalle, 2001).…”

The identification of skeletal elements, the analysis of their developmental sequence, and the time of their appearance during larval development are essential to broaden the knowledge of each fish species and to recognize skeletal abnormalities that may affect further fish performance. Therefore, this study aimed to provide a general description of the development of the entire skeleton highlighting its variability in Cichlasoma dimerus. Larvae of C. dimersus were stained with alcian blue and alizarin red from hatching to 25 days posthatching. Skeletogenesis began with the endoskeletal disk and some cartilage structures from the caudal fin and the splachnocranium, while the first bony structure observed was the cleithrum. When larvae reached the free‐swimming and exogenous feeding stage, mostly bones from the jaws, the branchial arches, and the opercle series evidenced some degree of ossification, suggesting that the ossification sequence of C. dimerus adjusts to physiological demands such as feeding and ventilation. The caudal region was the most variable regarding meristic counts and evidenced higher incidence of bone deformities. In conclusion, this work provides an overview of C. dimerus skeletogenesis and lays the groundwork for further studies on diverse topics, like developmental plasticity, rearing conditions, or phylogenetic relationships.

“…In these main lines, the dentition of † Sorbinicharax verraesi resembles certain cichlids or centrarchids for instance. These fish have a relatively flexible diet, ranging from snails and bivalves to omnivory [ 24 ]. Notwithstanding, the authors noted also a variable response of their teeth to their diet, from more delicate and pointed morphologies to crushing dentition.…”

†Sorbinicharax verraesi: An unexpected case of a benthic fish outside Acanthomorpha in the Upper Cretaceous of the Tethyan Sea

†Sorbinicharax verraesi is a marine teleostean fish from the Upper Cretaceous of Nardò (Italy). It was first attributed to the otophysan order Characiformes, which represents potential evidence for the controversial marine origin of the clade. Through a review of all the available material, we demonstrate that this species is not an otophysan since it lacks key structures that would allow for its inclusion in this group. †Sorbinicharax has a body shape that recalls ground fishes classically assigned to Acanthomorpha. However, no unambiguous feature allows us to relate it to this clade. In fact, the presence of cellular bony tissue supports its exclusion from Eurypterygii. Since no feature permits the definitive attribution of †Sorbinicharax to any teleost group, it remains as Teleostei incertae sedis. We infer that the morphology of †Sorbinicharax indicates a benthic ecology. It displays: an anteriorly wide body with enlarged ribs; large pectoral fins, while anal and dorsal fins are reduced; a large head measuring ¼ of the total body length; and a mouth opening dorsally in a high position. Such morphology was so far undescribed in Nardo. It is surprisingly displayed by a non-eurypterygian teleost fish which means by a fish which does not belong to the clades that diversify since the upper Cretaceous and include the extant families that show ground ecomorphologies.
