FOR DECADES, HAWAII HAS played an essential role in the U.S. aquarium trade. Its well-studied, regulated fisheries are now in limbo — causing ripple effects that pet retailers nationwide are feeling firsthand. It also serves as a cautionary tale about how activist-driven litigation and regulatory gridlock can disrupt the pet industry, even when the underlying science is clear.
Sustainability in Place
Hawaii’s aquarium fish are sourced from renewable, natural resources and managed under strict state oversight. The West Hawaii fishery, for example, is backed by decades of population data, species-specific catch limits, protected marine areas and ongoing scientific monitoring. Popular species such as yellow tangs and kole tangs have been closely studied for decades. Management measures implemented in the late ‘90s showed populations responding as expected under regulated harvest, with broader population fluctuations driven primarily by natural climate cycles — not aquarium collection.
Management in West Hawaii has focused on protecting adult breeding populations while allowing limited, regulated collection of juveniles — an approach supported by long-term monitoring and commonly used in sustainable fisheries. This balance allowed the fishery to operate responsibly while maintaining healthy populations over time.
Litigation Stalls Collection
Despite a strong sustainability record, legal challenges brought by groups opposed to aquarium collection have led to a protracted permitting stalemate, effectively halting operations even as scientific evidence supports continued sustainable fishing.
In 2017, litigation forced Hawaii’s aquarium fisheries to undergo an environmental impact statement (EIS) process despite that the state’s environmental law was never written to apply to fisheries. After years of delay, extensive analysis and significant costs, the West Hawaii fishery completed the EIS, addressed concerns and ultimately received approval. Under the state’s own rules, that approval cleared the way for permits to be issued.
Yet, as of today, no permits have been released. The Board of Land and Natural Resources (BLNR) approved the proposed rules by the State Division of Aquatic Resources to re-open the fishery. The rules are moving through the rulemaking process, and will be back before the BLNR in early summer after public procedural meetings for a final decision. Retailers will also have the opportunity to participate by submitting testimony.

Impact on the Industry
For retailers, the effects on this permitting stalemate have been real — fewer fish, higher prices, longer lead times and reduced species diversity — and will continue to grow until the issue is resolved. That matters not just to fish retailers but also to product suppliers who rely on healthy aquarium traffic to sell tanks, filters, food and accessories. When live fish disappear from stores, entire product categories suffer alongside them.
Hawaii is uniquely difficult to replace. Many marine species cannot be sourced elsewhere in the world. While captive breeding plays an important role, breeding saltwater species at scale remains challenging. Responsibly harvested wild fish are often healthier, more resilient and better adapted to aquarium life — outcomes that benefit both animals and consumers.
What is often misunderstood is that responsible aquarium fisheries are not the enemy of conservation. In Hawaii, it was the fishers themselves who helped build sustainability standards, supported scientific monitoring and operated within protected reef systems. These fisheries have survived scrutiny for decades because the data consistently support their practices.
The takeaway for the broader retail community is straightforward: This is not just a Hawaii issue. It reflects a wider pattern in which lawful, regulated supply chains can be disrupted by process rather than science. When one of the most well-studied and sustainably managed aquarium fisheries in the world cannot clear today’s regulatory hurdles, retailers across the country feel the consequences — from limited availability and higher costs to reduced product diversity and fewer customers coming through their store doors.
