- Determinism and causative factors for morphological anomalies in reared European fishesPublication . Boglione, C.; Fontagné, Stéphanie; Gavaia, Paulo J.; Gisbert, Enric; Kjorsvik, E.; Koumoundouros, Giorgos; Moren, M.; Moutou, K. A.; Witten, PaulThe presence of sublethal morphological deformities represents one of the main bottleneck of the industrial finfish hatchery production, resulting in major economic loss due to reduced growth and marketing ability of the final product, that has to be transformed (filets) or sold for fish flour. Furthermore, the elimination of deformed fishes from the productive cycle needs for periodic selections at present carried out by manual sorting. This represents an additional economic cost, and a stress for fishes.
- Skeletal anomalies in reared European fish larvae and juveniles. Part 1: normal and anomalous skeletogenic processesPublication . Boglione, Clara; Gavaia, Paulo; Koumoundouros, Giorgos; Gisbert, Enric; Moren, Mari; Fontagne, Stephanie; Witten, Paul EckhardThis critical review summarizes the knowledge about fish skeletal tissues and inherent normal and anomalous development. Particular emphasis is given to existing literature on reared European fishes. The aim was to identify the main gaps of knowledge that require to be filled, in order to precociously identify anomalous developmental patterns that lead to skeletal anomalies in reared finfish larvae and juveniles. The review also aims to extend our knowledge about the factors that are possibly involved in the onset of skeletal anomalies. The final goal is the optimization of the morphological quality of farmed juvenile fish.

Boglione, C.; Gavaia, Paulo J.; Koumoundouros, Giorgos; Gisbert, Enric; Moren, M.; Fontagné, Stéphanie; Witten, PaulThis critical review summarises the knowledge about fish skeletal tissues and inherent normal and anomalous development. Particular emphasis is given to existing literature on reared European fishes. The aim was to identify the main gaps of knowledge that require to be fulfilled, in order to precociously identify anomalous developmental patterns that lead to skeletal anomalies in reared finfish larvae and juveniles. The review also aims at to extending our knowledge about the factors that are possibly be involved in the onset of skeletal anomalies. The long period goal is the optimization of the morphological quality of farmed juvenile fish.
- Skeletal anomalies in reared European fish larvae and juveniles. Part 2: main typologies, occurrences and causative factorsPublication . Boglione, Clara; Gisbert, Enric; Gavaia, Paulo; Witten, Paul E.; Moren, Mori; Fontagne, Stephanie; Koumoundouros, GiorgosThe presence of skeletal anomalies in farmed teleost fish is currently a major problem in aquaculture, entailing economical, biological and ethical issues. The common occurrence of skeletal abnormalities in farmed fish and the absence of effective solutions for avoiding their onset or definitely culling out the affected individuals as early as possible from the productive cycle, highlight the need to improve our knowledge on the basic processes regulating fish skeletogenesis and skeletal tissues differentiation, modelling and remodelling. Severe skeletal anomalies may actually occur throughout the entire life cycle of fish, but their development often begins with slight aberrations of the internal elements. Comprehensive investigation efforts conducted on reared larvae and juveniles could provide a great contribution in filling the gap in knowledge, as skeletogenesis and skeletal tissue differentiation occur during these early life stages. The aim of this review is to provide a synthetic but comprehensive picture of the actual knowledge on the ontogeny, typologies and occurrence of skeletal anomalies, and on the proposed causative factors for their onset in larvae and juveniles of European farmed fish. The state-of-art of knowledge of these issues is analysed critically intending to individualize the main gaps of knowledge that require to be filled, in order to optimize the morphological quality of farmed juveniles.
