Formations of rocks, gravel, or sand created by current, wind, and weather form a compressed and lifted seabed, which provides fish with optimal conditions. There is often a huge water flow on these reefs. The depth is often greater on the sides of a reef, which means that the current will often be stronger there. Shoals of smaller fish roam in proximity to reefs in order to hunt, since the small food options are whirled around in the current. In their wake, the sea trout and other predatory fish follow. Reefs are useful spots year round, and they are optimal stops for sea trout when they migrate. Spending more time than usual on such a spot can easily be worth it.
When the coastline makes a dramatic turn and/or forms a kind of reef or isthmus, we call it a point. Similarly to a reef, points will often experience a more significant current, since the waters are here being pressed by. This yields great water circulation and is thus a good indicator of a sea trout spot. The water surrounding a point can be very deep, which means fishing for more species becomes an option, particularly during the warm months when the water temperature is high.
Along with the eelgrass, bladder wrack is the most prevalent aquatic plant along the Danish shores. This seaweed attaches itself to smooth surfaces such as rocks, gravel, and other variations on the bottom. The bladder wrack is a good hiding place for food options and fish. Bottom conditions with bladder wrack are good indicators of fish being nearby.
This aquatic plant functions as a brilliant hiding place for the small food options, and simultaneously they oxidize the water around them, which provides small fish, shrimp, and sand hoppers with good living conditions. The eelgrass is also used as a resting place for the sea trout when it migrates along the coasts and particularly in late fall when the trout are headed for the river.
The coastal sandbar is characterized by shifting water depths, where the bars are often made of sand that gathers between the deeper parts. These types of coasts can be exciting to explore, especially when great variations in the tide occur. The deep parts between the bars are called rip channels, and depending on the water level, the predatory fish will migrate over the bars and both in and along the rip channels. In spring, when the water temperature is rising, you can experience some fascinating sea trout fishing between these bars.
A rip channel is a deeper area between coast and bar, or an underwater groove of a significant depth. A rip channel usually has a dark bottom shaped by rocks and bladder wrack, but it can also consist of pure sand or gravel. You can’t avoid finding these rip channels on the coast, since they are some of the most common bottom conditions in Danish waters. The size of a rip channel varies greatly. Even the smallest rip channels, only a few meters wide, can contain many fish. The sea trout swims around these rip channels to hunt for food. In line with the tide, the fish cross the bars to reach the rip channel that’s closest to land, since that often contains the most food options.
