After his death, Ms. Ui Aodha bought a trawler and took to the sea again. She assumed she would sell the boat when she retired, but things had been difficult for years, and decommissioning felt like her only option. Her boat was scrapped in late April.

“The saddest thing really is to see how, all around the coast, indigenous fishing people like me become extinct, we’re just not going to be there,” she said, rattling off the names of longtime fishing families. “All these names are disappearing.”

But she also spoke with hopeful resilience about what comes next. The restaurant will be called Iasc, or fish in Irish. Photos of Ms. Ui Aodha’s father with his boat adorn the wall, she pointed out, as she walked through the unfinished space.

“I’ve done what I can and we’ve changed now, and this is just something new,” she said, reflecting on her years of fishing. “So I am bringing my world in here.”
