Fish close to the geological structure
Fish close to the bottom, such as: six-line fish, Xu flat catfish, black sea bream, sea bass, they react dexterously and are good at surprising weak targets, so they need habitat requirements. There are obstacles to hiding your tracks. However, waters with obstacles actually include: landforms with numerous grooves and reefs, as well as zones of intersection of salt and fresh water established at the mouth of the Yellow River and the Yellow River, offshore inland bays with deep-water reef provinces and large and medium-sized reef groups connected to beach areas, shingle beaches with sparse seaweed in the intertidal zone, culverts for water diversion and drainage pipes for agriculture on tidal plains, harbor breakwater roots and shipping routes. ,etc. The more "dirty, messy and worse" this landform is, the better it will be, because the ocean currents flow slowly there, and there are many marine animals adhering to it, and the weak baitfish must congregate here, so it is l The place where fish live and feed. However, it should be noted that on fine sand seabeds, there are very few fish near the bottom. Even though there are individual freshwater fish, they are very small.
Pelagic fishesPelagic fishes have relatively loose requirements for the geological environment of the seafloor. As long as the water body is clean and the depth of the water level is qualified, their shadow will appear. In particular, mackerel and small mandarin fish are very fond of this type of marine area and often live there in groups. The difference is that mackerel is a fish with very obvious migration patterns and seasons, while squid is more alert andreacts very immediately to changes in weather factors.
If the sea area where they live is about to become windy, they will disappear without a sound. Therefore, when fishermen choose fishing grounds, they must not only consider the season, but also the habitat habits of the main fishing species. Of course, water quality testing standards, meteorological factors and the regularity of tides and flooding cannot be ignored.
In coastal areas, we often find marine areas covered with aquatic plants and algae. Some zooplankton will grow in this kind of marine plants, hiding some small fish and shrimp, and at the same time, it can also reduce the impact of strong winds and waves to a certain extent. The head-throwing fish can not only catch some small fish, shrimp and other microorganisms, buts also swim towards algae and aquatic plants anytime and anywhere to avoid enemies and ensure their own safety. Therefore, many fishing enthusiasts often fish here and get good results every time.
