    DESCRIPTION
    System and procedure for octopus culture.
    Object of the invention
    The present invention belongs to the aquaculture sector. In particular, the present invention relates to a system for the cultivation of octopuses as well as to the corresponding culture procedure in said system.
    Background of the invention
    Although octopus (Octopus vulgaris) systems are known for systems in tanks on land, in particular referred to the fattening phase (juvenile to adult culture phase), the results obtained to date through such systems are not fully satisfactory , the design of systems that, in combination with non-technical aspects, improves the productivity of said crops being desirable. The present invention, which refers to both a technically improved system with respect to the systems that make up the state of the art, and a culture procedure associated with said system, responds to said desire or need.
    Description of the invention
    The invention relates to a system for the cultivation of octopus (Octopus vulgaris), particularly referring to the fattening phase (juvenile culture phase, less than one kilogram in size, to adults who can achieve a weight of 3 kilograms or more), which it comprises a preferably circular tank of large dimensions and optimal design for the recirculation of water in which modules are introduced in which octopuses in culture take refuge and from which said octopuses remain most of the time as a result of the cultivation procedure, in particular of the process of feeding them, so that a constant and quality growth is obtained thanks to the high energy conversion that the octopuses obtain from said feeding is mainly destined to their growth avoiding their wastage, for example, in the food search even if they maintain a territorial interaction with other octopuses.
    The tank maintains conditions and has characteristics very similar to the marine environment, particularly in regard to salinity, water temperature, oxygen concentration in water, and light intensity, for which the system comprises a hydraulic system that controls the recirculation of the water, an aeration system, preferably fine bubble diffusers, and a structure, for example a shade mesh, to reduce both the luminosity and the temperature of the tank subjected, for example, to the direct incidence of sunlight, avoiding in all possible factors that could generate stress in animals
    Therefore, a first object of the present invention relates to a system for the cultivation of octopus (Octopus vulgaris) comprising a tank, preferably circular, inside which, preferably in the perimeter wall thereof, shelter modules are located (whose proportion must be greater than the number or density of octopuses in the tank), a hydraulic water recirculation system, a water aeration and oxygenation system, and a structure or upper cover for regulating the luminosity and water temperature. In a particular embodiment of said first object of the invention, the tank is circular. In a particular embodiment of said first object of the invention, the shelter modules are made of concrete or similar material and are double,

    that is, two shelters per module shelter. In a particular embodiment of said first object of the invention, the aeration and oxygenation system consists of fine bubble diffusers. In a particular embodiment of said first object of the invention, the upper structure for regulating the luminosity and water temperature is either a shade mesh with a density of 100% (that is, it does not let the light in) with an opening or several upper zenithal openings that let the light through and in turn allow the circulation of air between the interior and the exterior, thereby regulating the temperature of the tank and the water contained in it, either a shade mesh with a density less than 100% without opening or additional openings.
    The invention also relates to the process for the cultivation of octopuses in a system such as that which constitutes the first object of the invention, said procedure based, among others, on an adequate management of the feed (which is carried out in a controlled manner, animal to animal) of the animals and the maintenance and cleaning of the system.
    In this way, once the animals have been transported to the system for cultivation from the place of capture, prior to their release in the tank, release that is preferably carried out individually to individual, acclimatization is performed, even within the transport system, generally a large cubic container, which implies the progressive change of the water of the transport system by water, preferably filtered marine water, from the culture tank or by water of characteristics (salinity, oxygen concentration, temperature) similar to those of the water of the culture tank. As indicated, it is after such acclimatization that the animals are released, preferably from individual to individual. The release of individuals also meets the total density of individuals in the tank, a maximum density of one animal per cubic meter being ideal. Likewise, said density also serves the number of shelter modules located in the tank, with a minimum density of one animal per three shelters being ideal (in the case of double shelter modules, that is, comprising two shelters per module, the ideal density It is two animals for every three shelter modules).
    Once the animals are released in the culture tank, both the individual feeding of the animals and the cleaning of the tank are carried out daily. Preferably, the feeding of the animals is done morningly and includes white fish, without head or tail to minimize the accumulation of debris in the tank. More preferably, the amount of white fish with which each animal is fed corresponds to a maximum weight equivalent to 20% of the octopus's weight. Even more preferably, the feeding with white fish is complemented with crabs.
    Therefore, a second object of the present invention relates to a process for the cultivation of octopus (Octopus vulgaris) comprising the following stages: acclimatization of the animals prior to their release, individualized release and controlled density of the animals once acclimatized, daily and individualized feeding of the animals in culture, and daily cleaning of the culture tank.
    In a particular embodiment of said second object, the acclimatization is carried out even within the transport system and implies the progressive change of the water of the transport system by water of the culture tank or by water of characteristics (salinity, oxygen concentration, temperature) similar to the water in the culture tank. In a more particular embodiment, the water with which the water in the transport system is progressively replaced is filtered seawater.

    In a particular embodiment of said second object, the individualized release is carried out so that the density of animals with respect to the volume of culture is at most 1 animal per cubic meter, and so that the density of animals with respect to the number of shelters located in the culture tank, it is a minimum of 3 shelters per animal.
    In a particular embodiment of said second object, the feeding is carried out morningly and comprises white fish without head or tail. In a more particular embodiment, the amount of white fish with which each animal is fed corresponds to a weight of white fish equivalent to a maximum of 20% of the octopus weight. In an even more particular realization, feeding with white fish is complemented with crabs.
    Other advantages and characteristics of the invention will be apparent in view of the description.
