Popis:	Summary A major problem for the fish farming industry is to find reliable indicators of bone condition that could help to prevent vertebral abnormalities. Here, we summarize the main results of two recent studies aiming to assess the variation of two vertebral bone variables (bone mineralization and vertebral total bone area) during rainbow trout grow-out in several French farms. We provide evidence for a wide range of variation for these parameters and for the occurrence of vertebral bone abnormalities, and new data on vertebral structure in trout reared either in various fish farms (influence of rearing conditions) or at different temperatures (influence of various growth rates). Although further experiments are needed to understand bone metabolism in trout, these findings increase our knowledge on growth and modelling of vertebrae, and provide valuable data that will enable comparisons in the future.
