St Andrews Bay Fishery


St Andrews Bay is sandwiched between the estuaries of the river Tay and Forth.  It's a fairly shallow piece of water with sand in the North thinning out to rocks in the South. The lobster fishery is mainly in the rocky South in depths of up to 20m.

St Andrews-A bay of 3 Rivers

On the map the Forth looks very impressive, but the river Tay is actually the largest river in Britain in terms of flow rate and the longest river in Scotland.  The flow of the Tay can hit over 1000m3 every second at Ballathie.

Even in flood the River Forth only manages about a 10th of that at around 114m3/sec at Carnforth. So whilst it looks impressive the Forth is outclassed by it's more Northerly neighbor.

St Andrews Bay itself has only one significant river which is gauged by SEPA The River Eden is a very modest affair with a mean flow rate of 4m3/sec.

So the major freshwater influence on the Bay is the River Tay at the Northern edge of the Bay. This brings a plume of freshwater and sediment swinging down into the bay from the North. Maintaining sandy bottom conditions in the Northern part of the Bay.

St Andrews Bay-A Special Place

St Andrews Bay is a very well protected environment. No mobile or active fishing gear is allowed in the Bay. That means no trawling for fish or prawns, no seine nets, no dredging for clams etc and no drift nets . For all practical purposes the only fishing allowed is creel fishing for Lobster and Crabs. Creel fishing uses static gear which is placed on the seabed and doesn't move; the advantage of this is that it causes very little damage to the seabed and has minimal by-catch.
