Even though walking around on rocks along the coast may feel annoying, it’s often a good indicator of the presence of optimal bottom conditions for the sea trout and its food options. Everything from pebble to huge chunks of granite provides cover for sand hoppers, shrimp, and small fish. If there are waves, these food options are easily whirled up into the water column. A rocky bottom can be good all year round, but especially so during the cold months with few food options in the deeper water. A rocky bottom at a good depth also attracts other predatory fish such as cod and garfish.
In many fishing spots, large areas of the bottom are covered in sand, and often the coastal angler will skip these areas since they don’t seem like much. However, it’s worth considering that many small fish like sand eel and sprat often migrate across the sand bottom, and they have sea trout and other predatory fish chasing them. On days with waves, unclear water, or dimmed lighting, you’ll likely find predatory fish in these areas. The sandy areas along the deeper water or close to dark areas can be true sea trout magnets.
In deep water fishing spots, variety abounds – both in terms of fish and types of fishing. In summer, the deep water can be several degrees colder than the shallow, coastal water. This may attract predatory fish that prefer the cold water. In winter, a similar situation is in play, since the deep water is warmer than the surface water.
