MARINE (S,M and L) is a soft food in the form of sinking granules (S size) or sinking chips (M and L) for omnivorous marine fish. It contains herring and insect larvae which provide high-quality protein and Omega-3, Omega-6 and Omega-9 fatty acids. It contains crustaceans and molluscs (krill 10.5%, squid 6%, calanus 1.7%) and algae (Spirulina platensis 12%, Ascophyllum nodosum 3%, Laminaria digitata 1.8%, Chlorella vulgaris 8%), which are the source of protein, carotenoids, minerals, prebiotics and other. It improves fish’s immunity and intensifies their coloration thanks to the high content of carotenoids from krill, calanus and red pepper.
