Cod fishing remained dominant but sealing also became important after 1820, as specially designed ships sailed each spring to intercept the great herds of seals on their annual southern migrations. The northern outports grew in importance ("outport" is used for all fishing ports except St. John's). By the 1850s new formed local banks became a source of credit, replacing the haphazard system of credit from local merchants. Prosperity brought immigration, especially Catholics from Ireland who soon comprised 40% of the residents. | Cod fishing remained dominant but sealing also became important after 1820, as specially designed ships sailed each spring to intercept the great herds of seals on their annual southern migrations.
