Hoki Oil vs Salmon Oil: What’s Actually Better for Your Pet?

Fish oil is one of the most commonly used supplements for dogs and cats — but not all fish oils are the same.

Differences in fish species, sourcing, and environmental impact can significantly influence both sustainability outcomes and how pet owners feel about the choices they make.

Two of the most discussed options are hoki oil and salmon oil. Understanding how they differ helps pet owners make more informed, responsible decisions.

Why Fish Species Matters in Pet Supplements

Fish oils vary widely depending on:

Species

Habitat

Population pressure

Harvest methods

Long-term ecosystem management

While many fish oils provide omega-3 fatty acids, the context in which the fish is sourced plays a major role in environmental responsibility.

This is where comparisons between hoki and salmon become important.

Hoki: A Sustainability-Led Fishery

Hoki (Blue Grenadier) is harvested primarily from New Zealand waters under one of the most tightly regulated fisheries management systems in the world.

Key characteristics of hoki fisheries include:

1. Science-based quota systems
2. Long-term stock management
3. Independent sustainability certification
4. Ongoing ecosystem monitoring

Hoki was also the first species globally to receive Marine Stewardship Council (MSC) certification, setting a benchmark for responsible fishing practices.

Salmon: A More Complex Sustainability Picture

Salmon oil is widely available and commonly used, but sustainability can vary depending on:

• Whether the salmon is wild-caught or farmed
• Feed sources used in aquaculture
• Local environmental pressures
• Waste and water-quality management

Some salmon fisheries and farms operate responsibly, while others face challenges related to overfishing, habitat impact, or ecosystem strain. This variability makes it harder for pet owners to assess sustainability at a glance.

Omega-3 Profiles: Similar Goals, Different Paths

Both hoki oil and salmon oil provide omega-3 fatty acids that are commonly included in pet nutrition.

However, omega content alone does not tell the full story.

Factors such as:

• Species consistency
• Harvest timing
• Processing care
• Traceability

all influence the final product. Oils sourced from well-managed fisheries tend to offer greater consistency and transparency — qualities that matter to increasingly informed pet owners.

Environmental Impact Beyond the Bottle

When choosing a fish oil, environmental considerations extend beyond the supplement itself.

Sustainably managed fisheries help:

1. Maintain healthy fish populations
2. Protect marine ecosystems
3. Reduce pressure on vulnerable species
4. Support long-term food security

Pet products sourced from responsibly managed fisheries allow owners to align daily care with broader environmental values.

Why Transparency Matters

As pet owners become more conscious consumers, transparency plays a growing role in trust.

Clear sourcing information, traceability, and independent certification make it easier to understand how a product fits into a sustainable future — not just a supplement routine.

For Newflands, this has never just been a “which fish oil has omega-3?” question. I chose hoki because source, traceability, sustainability, and practical daily use all matter. After using hoki oil with my own dogs, I wanted a fish oil that made sense for pets, owners, and the environment — not just something that looked good on a label.

Making Informed Choices for Pets and the Planet

Fish oil can be part of a thoughtful pet-care routine, but sustainability should always be part of the conversation.

By looking beyond the label and understanding how different fish oils are sourced, pet owners can make choices that reflect both care for their animals and respect for the marine environments those ingredients come from.

Looking Forward

The future of pet nutrition depends on responsible sourcing, transparency, and long-term thinking.

Comparing options like hoki and salmon oil isn’t about declaring one universal solution — it’s about understanding impact, sustainability, and the values behind the products we choose.

Common Questions About Hoki Oil vs Salmon Oil

Is hoki oil better than salmon oil for pets?

Hoki oil and salmon oil can both provide marine omega-3 support, but they are not identical. Hoki oil may be a better choice for pet owners who want a New Zealand-sourced oil, strong traceability, a milder smell, and a sustainability-led fishery. The best choice depends on your pet, their tolerance, and the quality of the oil.

Is salmon oil bad for pets?

No. Salmon oil is not automatically bad for pets. A good-quality salmon oil can provide omega-3 EPA and DHA. The issue is that salmon oil quality can vary depending on sourcing, farming or wild-caught status, freshness, processing, storage, and sustainability. Pet owners should look beyond the fish name and check the quality behind the oil.

Why does sustainability matter when choosing fish oil?

Sustainability matters because fish oil comes from marine resources, and those resources need to be managed responsibly. Choosing a traceable, well-managed fish oil helps support healthier oceans, long-term fish populations, and more responsible pet wellness choices. At Newflands, this is part of our Love of Land and Sea philosophy.

Does hoki oil smell different from salmon oil?

It can. Hoki oil is often milder in smell and taste than some stronger fish oils, which can make it easier for dogs and cats to take consistently. Smell can also be affected by freshness, storage, packaging, and how carefully the oil has been handled, so a mild oil from a traceable source can be easier for pet owners to use daily.

Which fish oil is best for sensitive pets?

Sensitive pets may do better with a mild, traceable, single-source fish oil that is easy to add to food and accepted consistently. Newflands uses New Zealand hoki oil because it is a gentle marine source of omega-3 EPA and DHA, with a milder smell and strong traceability. If your pet has allergies, medical issues, or is on medication, check with your vet before changing supplements.
