Farming remarks

Seriola lalandi is a member of the family Carangidae. It is a PELAGIC, gregarious species that can be found in temperate and subtropical waters of the Southern Hemisphere. While being a popular target for recreational fisheries, it is not considered at conservation risk. Commercial farming is well-established in Australia and expanding to New Zealand, Chile, Peru, and Northern Europe. Reasons for this development are the fast growth of up to 3 kg per year and easy reproduction – although currently, some farmers still rely on wild-caught breeders. Rearing consists of a hatchery stage until FINGERLINGS size and then transfer to tanks or sea cages where the IND are grown out for 12 up to 32 months.

Despite growing interest in S. lalandi for aquaculture, its ecology during the early life stages and its migratory patterns are not fully understood. Having a carnivorous diet means an unsustainable feed in farms and makes a complete replacement with feed alternatives impossible.

The WelfareScore is low due to higher spatial needs than captivity is able to provide, manipulations during reproduction, high stocking densities, aggression, missing substrate, handling stress, and high malformation rates. Non-assisted reproduction in captivity is possible. We need further knowledge whether high densities are compatible with a schooling species, keeping in mind that ADULTS in the wild can be solitary. Although S. lalandi is considered PELAGIC, it has been found over reefs or at fish-aggregating devices. Further research should show whether substrate in farms can be beneficial. A protocol for humane killing is available and applied – we need further knowledge whether it is the standard worldwide.

2025-07-08: Update WelfareCheck | farm: Seriola lalandi

We gave the WelfareCheck | farm of Seriola lalandi, the Yellowtail amberjack, an extensive update. Since its creation in 2017, we have adjusted the way we do entries and the way we score. This is now reflected in the updated profile which ended up with a lower WelfareScore than before.

Seriola lalandi is an ocean-dwelling species from the Southern hemisphere, praised for its excellently tasting meat which is used raw for Sushi. This manager of a fish farm, who abandoned Salmo salar in favour of Seriola lalandi, stresses the lower electricity bills, as the water does not have to be cooled anymore (for Salmo salar) but instead heated – which costs less. Does this make Seriola lalandi a good candidate for aquaculture?

There are numerous issues – on spatial needs, aggression, malformations, etc. – and the species is carnivorous which makes replacement of fish meal and fish oil hard. In the worst case, breeders are taken from the wild and manipulated to spawn, especially adults may suffer from high densities as they can live solitary in the wild, it is unclear whether the species would benefit from adding substrate, and we cannot be certain that ethical stunning is accepted as a standard worldwide. These were formely positively scored criteria that we downgraded.

Even though there are farming facilities that overlap with the wild needs, and there are proposals for mitigation measures for some of the issues, this was not enough to assume a good welfare in most of the criteria. All in all, the WelfareScore is low. To know more, explore the profile of Seriola lalandi and see the justifications for the scores in the WelfareCheck.
