Recommended culture conditions for the improvement of skin colour

There is an interesting potential for aquaculture as the results of the project have provided a way to solve the principal difficulty for the industrial commercialisation of red porgy, i.e., the maintenance of the natural colour.

This consists in two aspects:
- Specific adapted feeds supplemented with carotenoids.

- Recommendations regarding husbandry conditions.

Therefore, it is recommended:
- To culture fish in stocking densities up to 10 kg/m³.

- To use grey or light blue background weaning, pre-growing or on-growing (in the case of indoor close systems) tanks.

- To use (in the case of indoor close systems) low light intensities and blue lighting spectrum.

- To avoid water temperatures above 21°C. Optimum rearing temperature 17-19°C.

- To use shadow nets (in the case of sea-cages) to decrease the sun light intensity.

- To use feeds supplemented with appropriate carotenoids. Different formula feeds have been developed to improve the colour appearance

- To use the adequate formula feed between 2 to 3 months before harvesting of the fish.
