Silent auctions for aquariums, set up in minutes

Written for an organization that has spent years telling its audience what to buy — and now has to publish a catalogue.

Free for up to 20 items Unlimited bidders No credit card required

Your catalogue is read as advice

An aquarium is a conservation-messaging organization before it is an attraction. It publishes seafood guidance, runs plastics campaigns, tells school groups which species are in trouble and asks visitors to change what they buy.

That is the asset and it is the constraint. A supporter browsing your auction reads it as an extension of that advice, which means an item that contradicts your own published position is not a small inconsistency — it is the organization saying two things at once, in public, with its name on both.

The items this catches are ordinary ones a zoo would list without a thought:

  • A seafood dinner or a restaurant certificate, where the restaurant's sourcing is unknown or contradicts your guidance
  • A fishing charter, which is a common and popular donated item in coastal towns
  • Coral, shell, tortoiseshell or mother-of-pearl in jewellery or decor, including antique pieces
  • Aquarium-trade fish, tanks or livestock, where the trade's collection practices are part of what you campaign on
  • Single-use plastic in a gift basket, from an organization running a plastics campaign
  • A cruise or a flight-heavy trip, if your climate messaging is prominent

None of these is automatically disqualifying. All of them need a decision made in advance, by someone who knows the organization's positions, rather than by a volunteer sorting donations in week three.

Write the screen before you solicit

One page, agreed with the conservation or education side, listing what is accepted, what is accepted with conditions, and what is declined. Then give it to everyone asking for donations.

Doing it first solves the problem that has no good ending: a generous donor offers a fishing charter publicly, and you either accept something that contradicts your own campaign or decline in a way that reads as ungrateful. A screen written in advance lets a solicitor say "we can't take that one, but we'd love X" in the first conversation.

The corporate version of the same problem: conservation sponsorship.

Welfare policy still governs the animal items

Everything the zoo guide says about curatorial control applies here — the husbandry and veterinary teams decide what encounters, feeds, dives and back-of-house access are possible, and an agreed substitute is needed for every one of them. Aquatic systems add their own: water chemistry, quarantine and life-support work can close an area at no notice.

The mechanics are the same and are not repeated here: scoping an encounter. What differs for aquariums is on experience packages.

Sizing an ask against a membership that visits in winter

Working it out from membership and divers

An aquarium has one audience nobody else can reach and one ceiling set by operations.

  • Members, segmented by recent visit
  • The local dive community — shops, clubs and certification schools
  • Two average-bid figures: one for the family audience, one for in-water items

Full breakdown: how much can an aquarium raise?

When an auction is the wrong instrument

If the ask is an exhibit build or a life-support system replacement, that is capital and an auction will not reach it. If a rescue and rehabilitation programme is mid-event — a stranding, a cold-stun, an oil response — the husbandry team has no capacity for encounter items, and an emergency appeal is the instrument that moment calls for. And if your organization has a live campaign asking supporters to change their buying behaviour, launching a catalogue in the same fortnight puts the two messages side by side.

What an aquarium audience bids on

In-water and back-of-house experiences carry the bidding — an aquarium has access nothing else can offer, including a zoo. Everything else fills the catalogue and every item passes the screen.

Bundling a day, and writing the ask

Baskets work as a family day: membership, parking, lunch, and one behind-the-scenes stop. Where the organization runs field programmes, a bundle around a beach cleanup or a citizen-science survey is on message and costs nothing.

For the ask, name the thing in animal or programme terms — a season of a rescue programme, the water quality equipment, the school transport fund, a field partner's specific project. It is the honest description of where the money goes and it also gives the catalogue a purpose consistent with the screen.

Husbandry colleagues, then a screened outside list

Most of the catalogue comes from inside — husbandry, dive operations, veterinary, education, facilities. Outside donors are the smaller half and are the half the screen exists for.

Reaching the membership, and the divers

Channel order: the membership list, segmented by recent visit; the donor list; adopt-a-species and sponsorship participants; the local dive community, which is an audience an aquarium can reach and almost nobody else in fundraising can; education programme and camp families; corporate members; and local media, which will run an underwater photograph.

One move worth building in: the dive community. Local dive shops, clubs and certification schools have members who will bid hard on an in-water experience and who mostly do not know the aquarium runs one. Two conversations opens that channel.

General mechanics: how to promote a silent auction and marketing templates.

Who receipts

Aquariums sit in the same structures as zoos — a society or foundation alongside a municipal, university or authority-operated facility. Establish which entity receives, what a donor may claim, and whether a gift needs formal acceptance before the auction page goes live.

And ask the displacement question once: does a donated item add to the operating line or replace it? A donor who funded a life-support pump that the budget then stopped covering has not funded a pump.

Twelve weeks, and two meetings before any asking

  • Week 12 — husbandry, dive operations and veterinary on the experience list: what is possible, how many can be supported, and the substitute for each
  • Week 12 — conservation or education, to write the donation screen. One hour, one page, and it is the meeting that prevents a public problem
  • Week 11 — which entity receives, whether a gift needs formal acceptance, and the displacement question answered before a goal is named
  • Week 10 — other departments; membership and retail coordination
  • Week 8 — dive shops and clubs, corporate members, field partners
  • Week 6 — the membership list and local business, screen in the solicitor's hand rather than in someone's inbox
  • Week 3 — catalogue closed. Every in-water item carries its certification level, medical requirement, transferability and alternative on the item page
  • Week 2-0 — bidding live. Dive community and recent-visit members mailed separately
  • Close + 1 week — book every experience through one person; report what each programme raised

Four jobs, and one is a screening job

  • Experience items — owns the husbandry and dive relationship, the capacity number, the conditions and the substitutes
  • Screening and procurement — holds the donation screen and applies it in the first conversation, not after an item is offered publicly
  • Promotion — membership segmentation, the dive community, media
  • Booking and fulfilment — one person books every in-water item so no diver fields calls

Where aquarium auctions go wrong

  • An item that contradicts your own guidance. A seafood dinner or a fishing charter listed without a decision, then pulled after bidding opens — which costs more than the item was worth
  • A dive item with no stated certification requirement, won by someone who cannot use it and cannot transfer it
  • Overcommitting dive operations because bidding suggested you could sell more. Raises more this year, loses the item next year
  • A description implying more than happens — "dive with sharks" sold to an expectation the actual experience does not meet
  • No substitute for a closed system. Life support, quarantine and rescue response close areas at no notice and none of it is the winner's fault
  • A sponsor whose record nobody checked, whose logo now sits beside your conservation message

What it costs, and the honest net

The direct cost is close to nothing — the catalogue is access and expertise the institution already has. The real cost is dive and husbandry time, which is why the capacity number is agreed in week twelve and treated as a ceiling rather than a target.

Worth naming for a board: the screen will decline some donated value. That is a real cost and it is smaller than the cost of the alternative, which is an organization publishing advice and a contradicting catalogue in the same week.

After it closes, and the second year

  • Book every in-water item immediately, through the one named person, with the alternative recorded
  • Keep the donation screen with the reasoning, so next year's solicitors inherit a policy rather than a set of remembered decisions
  • Keep the dive community contacts — shops, clubs and schools renew themselves as an audience
  • Ask winners for a photograph with specific permission; an underwater photo sells next year
  • Tell husbandry and dive what their items raised and what it funded

Aquariums silent auction FAQ

Can we auction a seafood dinner?

Only if the restaurant's sourcing is consistent with the guidance your own organization publishes. Your catalogue is read as an extension of your advice, so this is a decision to make in advance rather than when a donor offers one.

What should the donation screen cover?

One page agreed with the conservation or education side: what is accepted, what is accepted with conditions, and what is declined. Seafood, fishing charters, coral and shell, aquarium-trade livestock, single-use plastic and flight-heavy travel are the categories that need a position.

Why write the screen before soliciting?

Because the alternative has no good ending. A donor offers a fishing charter publicly and you either accept something that contradicts your campaign or decline in a way that reads as ungrateful. A screen lets a solicitor redirect in the first conversation.

What sells best at an aquarium auction?

In-water and back-of-house experiences — a dive in an exhibit, a feed, the life-support gallery, an animal health round. An aquarium has access nothing else can offer, including a zoo.

Do the zoo encounter rules apply to us?

Yes, in full — husbandry and veterinary decide what is possible and every experience needs an agreed substitute. Aquatic systems add water chemistry, quarantine and life-support work, which can close an area at no notice.

Which outside audience are we most likely to be missing?

The local dive community — shops, clubs and certification schools. Their members will bid hard on an in-water experience and mostly do not know you offer one.

What should the auction fund?

Something in programme terms: a season of the rescue programme, water quality equipment, the school transport fund, a named field partner project. It describes where the money actually goes and keeps the catalogue's purpose consistent with the screen.

Who receipts the bidders?

Usually a society or foundation alongside a municipal, university or authority-operated facility. Settle it before the page goes live, and ask whether a gift needs formal acceptance.
