Farming remarks

Hippoglossus hippoglossus
Li0  ❘  Po0  ❘  Ce5

Hippoglossus hippoglossus is a slow growing, cold water flatfish that can reach up to nearly 5 m and over 300 kg. It is endangered due to overfishing. It has a high market value, hence it has been in the focus of the aquaculture industry. However, its particular biology and life history makes this species inadequate to be farmed in welfare. Namely, its home and depth ranges are far greater than any method can satisfy, its reproduction is still largely dependent on invasive induction, it displays aggressive behaviour, requires specific shelter and substrate, and is very sensitive to common farming procedures. In addition due to its slow growth it requires many years of investment, and the metamorphosis in early stages demands extra good rearing conditions in order to produce healthy individuals. Potential for improvement lies principally in providing better conditions for non-induced spawning and proper feeding regimes to avoid aggression.
