Would it be possible to have a shellfish population without a fish population? I need the islanders to have some protein source should I decide not to go with wild pigs but don’t want an abundant source

Yes. But that doesn’t mean the shellfish will be easy to catch. Sandy of rocky shores may host some barnacle like critters on rocks, and an occasional crab or similar creature in shallow water, but the more abundant critters will be in deep water around protective structures like coral reef or just plain rock. They could easily be at depths unattainable for most people even if they some snorkeling gear. If there was a healthy coral reef around this island there would be finned fish in the water already.

On the other hand there may be a substantial number of land crabs available for food.

Could they be trapped instead, like lobsters (the ones that move, that is – clearly it’s difficult to lure barnacles into a trap)?

Turtles or birds would be an option. Both would probably be seasonal in nature, but you’d have nests to raid as well as adults. Of course, I don’t know my south Pacific wildlife well enough to know if any real species would fit the bill.

Wild pigs don’t need to be abundant. Even if they’re domesticated, they might not be abundant. Pigs need food of their own and if the islanders don’t have an excess of grain (or coconuts or whatever) then pigs are an inefficient use of their limited food supply.

I suppose so. Fish traps should work as well. But most of the life on reefs is in the corals and other fixed or slow moving invertebrates that wouldn’t enter a trap. You could probably pick up some reef shrimp that way, but you’re unlikely to be catching any oxymoronic jumbo shrimp. It keeps coming back to the same problem, sea shore life lives where there are nutrients and protection. When that’s available there will be food to catch. When it’s not available the potential food supply dwindles and becomes more difficult to catch.

There also needs to be sufficiently protected water to protect the fishing boats.

Note also the island could be fished out, like the first Survivor epi: It was set in the South China Sea on the remote Malaysian island of Tiga in the state of Sabah. Listed as being “overfished”. (and confirmed during the show).

The first Maori brought both chickens and pigs to New Zealand. Both species were allowed to become extinct in very short order. That may have had something to do with the difficulty in growing tropical Polynesian crops in temperate new Zealand, but the fact that pigs survive quite fine in NZ with no care whatsoever suggests that every last pig was actively slaughtered, rather than dying from neglect.

The evidence suggests that this was because of the overabundance of large, delicious and completely naive birds, frogs and reptiles that covered New Zealand. People saw no need to waste time tending to chickens and pigs when they could literally kills thousands of frogs or dozens of Moa each morning. So the pigs and chickens were slaughtered once it became clear there was no reason to keep them alive.

Within 500 years people in New Zealand were slaughtering and eating each other because of desperate shortage of protein.

This article sez they did not bring chickens or pigs.

The Polynesian dog and rat came with the early arrivals, but the domestic pigs and chickens of the islands did not, for reasons not fully understood.

It is hard to see rodents as a viable protein source-there is so little meat on them, and preparing them would be a lot of work. It makes much more sense to gather shellfish-blue mussels are common around here-you can gather several pounds in a few minutes.

Indeed you can. But then they take 7 years or so to grow back to full size.

It’s probably not much work if you leave the bones in. How hard can tiny mouse bones be, really? Crunchy, like raw celery, I’m guessing\*. Skin and gut and pop 'em in the pot…surely no more work than cleaning shrimp.

Bigger rodents, like guinea pigs, are well enjoyed by many. I can buy them (cleaned and frozen) at my local Ethnic Market (but I don’t, because they’re $20 each!)

\*We’ll have to wait for Mangetout’s answer to be sure.

Goat’s cheese (and the occasional goat; you can’t kill them all and eat them if you need the milk & hair).

Sure, but I said “land mammal protein.”

When the Maoris arrived, the islands were teeming with many species of moas and several other kinds of flightless birds. But most of these were rapidly overhunted to extinction. A few varieties of flightless birds survived, but aside from kiwis and weka rails, were mostly pretty rare or confined to remote mountains.

The Maoris could also use marine mammals like seals and sea lions, dolphins, and the occasional beached whale. But the only native land mammals were a few species of bats.

Um, I doubt a rabbit would eat _me_?

As a rule, herbivores are more tasty than carnivores.

But mostly I think it’s that rats have bad press agents. The whole “vermin” classification, hundreds of years of folks saying they spread disease, living in trash. Rats just seem disgusting.
