Farming remarks

Dicentrachus labrax
Li0  ❘  Po3  ❘  Ce5

Dicentrarchus labrax is a valuable species for aquaculture. However many aspects of its biology are not taken into consideration in farming conditions, especially in intensive culture. Despite recent advances in nutrition, there is still dependence on unsustainable feed sources such as fish meal and oil. Many behavioural aspects are yet to be fully understood, namely on reproduction, where courtship processes are unknown and spawning has largely to be artificially induced. Spatial needs are also an issue, since farming conditions are generally too restrictive of natural movement. This species is known to be highly sensible to stressors at all life stages, although good practices can greatly reduce stress effects. A proper culture system, providing shelter and substrate, reducing densities based on natural numbers and increasing space are measures that should contribute to better farming practices.
