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 muddy and soft bottoms are often found in inlets, fjords, and brackish areas where outflow from rivers or drainage canals has transported sediment for many years. At the right times of year, these areas offer some fantastic fishing. From late fall till spring, the soft bottoms tend to be where the sea trout, for instance, can easily find food such as bristle worm, goby, and shrimp, since this type of bottom is a good heat insulator during winter.
When mussels fix themselves to the seabed, it often occurs in places with current and good water flow, so nutrients and food options will come to them. Mussels are good indicators of life, and it’s often near them you’ll find hunting sea trout. Besides creating banks and reefs that provide other fish with conditions of life, the mussels also clean the water, and that has a huge impact on coastal water quality and fauna.
