A head port from 1710 to 1827, since then a creek or sub-port of Kirkcaldy, Anstruther possesses a harbour of its own, enclosed by two piers; but, this being found too small, the Union Harbour was commenced at Cellardyke in 1866. With a western breakwater and eastern pier, both built of concrete, and the latter 1200 yards long, it has an area of 7 acres, and, owing to frequent interruptions from storms, was only completed in 1877, at a total cost of over £80,000. Its revenue was £616 in 1880; and Anstruther is head of all the fishery district between Leith and Montrose, in which during 1879 there were cured 9119½ barrels of white herrings, besides 127,705 cod, ling, and hake-taken by 775 boats of 8839 tons; the persons employed being 3175 fishermen and boys, 38 fish-curers, 80 coopers, and 2460 others, and the total value of boats, nets, and lines being estimated at £123,488. In the year ending 31 March 1881, the herring catch alone was 17,100 crans, against 8630 in the twelve months before. Anstruther-Easter was made a royal burgh in 1583, and Anstruther-Wester in 1587, but the latter lost its municipal status in 1852, not to regain it till 1869.
