Golden grey mullet (lat. Liza aurata) is a fish of the Mugilidae family. It is grey in colour with silver-white belly and large scales on its body. Its head is large and wide with a blunt tip and eyes close to the small mouth with protruded upper lip. Golden grey mullet can be easily recognized by its prominent golden spot on the gill covers, the yellowest compared to other species of the Mugilidae family with the similar spot. It loves brackish waters and can be found at the river mouths, even deep in the rivers. It is also common on other grounds along the coast.

Ćokalica is a small fish that lives in a layer of brackish water between the top layer of fresh water of the Krka River and the lower layer of salty sea water.

European Seabass (Lubin) is a fish that can grow up to 1 meter in length, and 14 kg in weight. Characterised by its predator appearance, it is strong and robust, but at the same time elegant due to its elongated body features. It swims very quickly. Its head is medium in size with a disproportionately large mouth and slightly protruding lower lip. European Seabass does not have large teeth, but they are numerous and very sharp. There are several pointed spines on the gill covers. Its body is covered with small scales, and it is of light lead-grey colour with silver-grey sides, silver-white belly and a black spot above the gill covers. The young, as well as some adults, have black dots at the top and along the sides.
It can be found along the entire Adriatic coast, regardless of the bottom composition, in the muddy and brackish, and also clear, salty sea. It mostly occupies the river mouths and bays with the presence of fresh water from underwater springs. It resides near the coast, mostly at small depths of 2 to 5 meters, although it can reach up to 80 meters deep and can be found deep in the river streams.

Eel The appearance of the eel is snake-like, it has a long, elongated body, its dorsal fin starts far behind the head, its tail ends striped, with a connection of the dorsal and ventral fin. Its lower jaw is slightly more elongated than the upper one, and the eyes are located at the very top of the head, immediately above the mouth. The colour of the eel is greenish or greyish-brown, with yellowish lower part. It is covered in a layer of mucus which allows it to pass through dense river vegetation, as well as creeping along the coast and through the muck at low water level.
