European perch

There is currently no specialized feed for European perch. Therefore, the feed used for commercial salmon is used, with a high content of fish oil. It takes 3 kilos of wild fish to grow 1 kilo of perch. The feed is not always sustainable because it may contain ingredients that are not caught or produced in a sustainable way. For this reason, the source usage scores orange.

The advantage of growing perch in recirculation systems or in flow-through systems with waste purification, is that a number of possible negative effects on the environment are limited. In addition, the system makes it possible to reduce water use. The impact on the environment is low, giving this section a green score.

The management plan for perch farmed in recirculation systems is very effective. For this reason, the management also scores green.

The final assessment for this species is green. This fish is a good choice and you can eat it without hesitation.

Fish in Season

This assessment concerns farmed fish. Therefore, the season is not important.

There is no regular stock estimation for perch as the species is not seriously threatened. This species is relatively unaffected by fishing pressure. The section fish stock and fishing pressure receives an orange score.

The use of traps and demersal gillnets has no negative impact on the ecosystem. There is however incidental bycatchBycatch:
Species caught next to species targeted for fishery. By-catches can consist of non-commercial species and species that are too small, and can be kept (this part is sometimes called by-product) or thrown back into the sea (discards).   of the critically endangered European eel. For that reason, the section ecosystem effects receives an orange score.

The management plan is considered partially effective and therefore receives an orange score.

The final assessment for this species is orange. This fish is a good alternative for species with a red score, but is not the best choice.

Fish in season

Fish in season is the best quality at that time because the spawning period is over.
