Mariculture in China is currently mainly focused on tidal flats, estuaries and shallow sea areas outside the bay. The excessive development of offshore mariculture has led to resource environment bearing capacity reaching or approaching the upper limit, and the eutrophication of the bay water quality, more sediment and more biological pollution in some areas are serious. Therefore, the development of deep-open sea culture is taken as an important means for constructing a modern marine industry system in many areas, the requirement for expanding the deep-open sea culture space is increasingly strong, the development of mariculture from offshore to offshore is promoted by means of modern engineering technology and information technology, offshore deep-water storm-resistant cage culture is developed, and a batch of deep-water cage culture bases are constructed. Thus, offshore areas will develop deep-open sea farming as an important means of constructing modern marine industry systems.
In the current offshore cage culture mode, a Norway cylinder mould is mainly adopted, and the structure of the Norway cylinder mould is an opening on the floating sea surface. The feeding mode is manual or mechanical air throwing, the feed is sprayed to the water surface from the air and gradually sinks, and the fish shoals gather on the surface water surface to eat. The feeding method brings two problems that one is that the method is only suitable for a full-floating net cage floating on the sea surface, and cannot be suitable for a semi-submersible or base net cage resistant to wind and waves. Secondly, even if the net cage is in a full-floating working condition, the shoal of fish is expected to stay in a deeper water area as much as possible, so that the waste of feed is reduced, the risk of infection of the shoal of fish with harmful microorganisms and parasites is reduced, the problem that birds fight for feed is avoided, and the bird prevention net is not needed to be additionally arranged.
In view of the above, it is highly desirable to design a multifunctional underwater feeding device for three kinds of net cages, namely full-floating, semi-submersible and bottom-sitting, which is matched with an intelligent feeding system to realize intelligent and full-automatic deep-open sea net cage feeding.
