The concept behind both is to raise money for the aquarium. If one does not have funds to donate, items can be offered up for raffle/auction to raise funds. This way everyone has an opportunity to participate.
For the raffle, tickets are bought and drawn from a hat. people can buy one or many tickets.
For auction items, bidding will continue until the highest price is reached at that moment.
A third option would be to donate $ directly which is fine too.
What one does with their winnings is their decision. If they wish to barter or divvy to others, that's their choice. This would also imply one should not bid on items of no interest.
