Abstract

System for the individual maintenance of live aquatic organisms. The aquariums are placed in a larger tank with a drain connected to a reservoir of water that contains the filtration system and maintenance of the physical-chemical conditions. A pump linked to the filtration system recirculates the water through a hose that, connected to a piece type "T", joins a closed circuit with another hose. The water pressure is equalized within the circuit, allowing a homogeneous flow in the multiple outputs that it presents. From these hoses are born that feed the aquariums with filtered water independently. With this invention, the visual, physical or chemical independence of organisms is achieved with each other, at the same time that they are offered an individual space suited to their needs. It can operate in closed or semi-open circuit. (Machine-translation by Google Translate, not legally binding)

Description

DESCRIPTION

Individual maintenance system of live aquatic organisms.

Sector of the technique

Technology related to the maintenance of several live aquatic organisms individually. It can be used in applications of aquaculture, research, teaching or transport of organisms.

State of the art

The present invention refers to a system for the individual maintenance of living aquatic organisms, such as octopuses or crustaceans, which allows their maintenance indefinitely without physical, chemical or visual contact with other organisms maintained in the same system.

The consumption of aquatic organisms, such as octopuses and crustaceans, has grown in recent years (Conners and Levine, 2017. Characteristics and discard mortality of Octopus bycatch in Alaska groundfish fisheries, Fisheries Research 185, 169-175). On the contrary, the catches in the middle are being reduced by diverse problems of anthropic origin. One of the solutions to continue producing this type of animal is to do it in controlled conditions of aquaculture (Food and Agriculture Organization of the United Nations).

Some of the problems to maintain these species in reduced environments are usually intraspecific aggression, cannibalism and competition for space.

The experience of cephalopod culture (where octopuses are framed) is scarce (Fiorito et al., 2015. Guidelines for the care and welfare of cephalopods in research-a consensus based on an initiative by CephRes.) FELASA and the Boyd Group, Laboratory Animals 49, 1-90). On the other hand, the cultivation of some species of crustaceans appreciated by the market has not yet been carried out, so that their consumption depends exclusively on the captures in the wild (Mehault, Morandeau and Kopp, 2016. Survival of discarded Nephrops norvegicus after trawling in the Bay of Biscay, Fisheries Research 183, 396-400).

Current systems for the maintenance of organisms such as octopuses comprise community structures where animals share the same volume of water (Garrido et al., 2017. Assessment of stress and nutritional biomarkers in cultured Octopus vulgaris paralarvae: Effects of geographical origin and dietary regime Aquaculture 468, 558-568), although physical barriers are established for their separation (ES 2121700, Hebberecht and Perez Homem de Almeida, 01.12.1998, JP 2017006054A, Masami et al., 12.1.2017). The options for the individual maintenance of the octopuses include designs where the animal is enclosed in a pot with holes and a screw cap inside a tank with other boats that contain more animals (CN 205802644 U. Zhang, 25.01.2017). The designs for transporting these live animals include their individual distribution in closed structures with holes, allowing the exchange of water with the outside, inside tanks maintained under conditions of regulated salinity and temperature, together with other structures with more individuals (CN 102124970A, Zheng et al., 20.07.2011). Until now, all the technology and methods available for the maintenance or transport of octopuses require systems where, although individuals are physically separated to avoid intraspecific aggressions, water is shared by several animals so chemical communication between them is inevitable.

Something similar happens with crustaceans, where several individuals are kept in the same volume of water (WO 03/037077, Mann, Asakawa and Pizzutto, 08.05.2003, US 4228762, Kemp, 21. 10.1980). The transport of these organisms is currently carried out in tanks with several animals inside, even in dry conditions, without enough water for the proper development of normal life activities in these organisms (US 5555845, Flynn, 09.17.1996).

It is known that certain metabolic residues and hormones produced by aquatic animals can affect other individuals, either by contamination of water with nitrogen compounds or by endocrine control (Deane and Woo, 2007. Impact of nitrite exposure on endocrine, osmoregulatory and cytoprotective functions in the marine teleost Sparus sarba, Aquatic Toxicology 82, 85-93). This endocrine control by hormones dissolved in water can cause changes in the state of sexual maturation (Phuc Thuong et al., 2017. The hormone 17B-estradiol promotes feminization of juveniles protandrous hermaphrodite false clownfish (Marine and Freshwater Behavior and Aquarium ). Physiology DOI: 10.1080 / 10236244.2017.1361788), in behavior (Saraiva et al., 2017. Chemical diplomacy in male tilapia: Urinary signal increases sex hormone and decreases aggression, Scientific Reports 7, 7636) or even produce responses due to a stress situation (Furtbauer and Heistermann, 2016. Cortisol coregulation in fish, Scientific Reports 6, 30334).

Stress responses can be divided into primary, secondary and tertiary (Barton, 2002. Stress in fishes: a diversity of responses with particular reference to changes in circulating corticosteroids, Integrative and Comparative Biology 42, 517-525). The primaries include the activation of the sympathetic nervous system, releasing catecholamine hormones from the chromaffin tissue (Reid et al., 1998. The adrenergic stress response in fish: control of catecholamine storage and release Comparative Biochemistry and Physiology C 120, 1-27), and the stimulation of the interrenal axis, which releases corticosteroid hormones into the circulatory system (Wendelaar Bonga, 1997. The stress response in fish, Physiological Reviews 77, 591-625). Secondary responses are defined as those actions produced by these hormones (Mommsen et al., 1999. Cortisol in Teleosts: Dynamics, Mechanisms of Action, and Metabolic Regulation, Reviews in Fish Biology and Fisheries 9, 211-268), summarized in liberation of energetic metabolites to the plasma, increase of the respiratory frequency to favor the availability of oxygen, and increase of the cardiac frequency to mobilize these substrates throughout the organism. Tertiary responses extend to the organism and population level (Wedemeyer et al., 1990. Stress and acclimation, in Methods of Fish Biology, Schreck and Moyle, eds, American Fisheries Society, Bethesda MD, USA, pp 451-489), affecting the performance of the animal (growth, reproduction and behavior), even reaching the death of the individual.

The nature of the hormones released and the secondary responses of these can vary between taxonomic groups and others. Thus, it is known that the primary responses correspond to the release of cortisol in teleost fish (Mommsen et al., 1999). of 1-hydroxycorticosterone in elasmobranchs (Hazon and Balment, 1998. Endocrinology, in The Physiology of Fishes , Evans, CRC Press, Boca Raton FL, USA, pp 441-464) and hyperglycemic hormone in crustaceans (Lorenzon et al., 1997). Lipopolysaccharide-induced hyperglycemia is mediated by CHH release in crustaceans, General and Comparative Endocrinology 108, 395-405).

The recovery process after a stress situation includes recovering the body's homeostasis to sustainable levels, either by returning to the basal state or by establishing an alostatic state (McEwen and Wingfield, 2003. The concept of allostasis in biology and biomedicine. Hormones and Behavior 43, 2-15).

Some scientific experiments have been carried out to evaluate the survival rates of octopuses (Conners and Levine, 2017. Characteristics and discard mortality of Octopus bycatch in Alaska groundfish fisheries, Fisheries Research 185, 169-175) and crustaceans (Mehault, Morandeau and Kopp, 2016. Survival of discarded Nephrops norvegicus after trawling in the Bay of Biscay. Fisheries Research 183, 396-400). However, all work has been done with the animals kept in the same volume of water, even if it were in structures that physically separated one from the other. This fact, as explained in the previous paragraph, can cause undesired metabolic responses as a result of chemical communication between individuals.

Therefore, to carry out studies of survival and recovery of aquatic organisms, such as octopuses and crustaceans, or to keep these animals in non-stressful or limiting conditions, and not to have problems derived from the communication between animals, a system of individual isolation. This system must also maintain adequate water quality conditions for the organisms it contains.

Description of the invention

The present invention has for its object a system for the maintenance of living aquatic organisms, such as octopuses or crustaceans, by means of which the animals are handled individually within the system, for an indefinite time and without physical, chemical or visual contact with other organisms. maintained in the same system, in closed or semi-open circuit.

According to the system of the invention, the animals are kept in separate aquariums that prevent the animals from leaving, but allow the water to be renewed from these compartments. These aquariums have opaque walls, avoiding the visual contact of the different animals, allowing the grouping of several aquariums in adjacent spaces.

The system allows the management of the aquariums independently, being able to be extracted from the system for cleaning or manipulation without altering the organisms of the adjacent aquariums.

The aquariums are grouped into modules with an independent filtering system for each module. These modules can be arranged on board ships or in fixed or mobile installations on land.

The general operation of the invention requires a water circulation system. This system can be closed or semi-open depending on the availability of clean water and / or the needs of the moment.

The clean water enters the aquariums through a hole in the lid of the aquarium, and is carried to the bottom of the aquarium. Ahl creates an upward current and exits by overflowing through holes in the top of the aquarium. Aquariums should pay special attention to possible escape routes of the organisms they contain. To this end, the invention includes the closing of the covers by suitable systems (pressure bands, flanges, clamps, wires, ropes, etc.), as well as the size adjustment of any entry / exit hole to the aquariums to avoid the escape of organisms through them.

The water that comes out of the aquariums is collected in a structure where the aquariums are kept, which has an outlet drain. This water is carried, by gravity and without the need for automation, to a water reserve container.

The water reservoir in turn allows the entry of a clean water conduit to adapt the system to a semi-open circuit regime. In this mode of action, the excess water in the system exits by overflowing from this reservoir.

The amount of oxygen in the water is maintained at adequate levels for aquarium animals by the inclusion of an air / oxygen diffusion system within the water reservoir.

The temperature of the water, another relevant factor for the correct maintenance of the animals can be controlled by the incorporation of heating / cooling systems in the water reservoir.

Within the reservoir the invention includes a filtration system suitable for maintaining the water conditions of the aquariums sufficiently clean. This includes the elimination of nitrogenous waste, waste substances, residual molecules resulting from the metabolism of organisms, as well as hormones or other substances produced by animals that could reach other individuals and provoke responses to them.

The filtration system is the most variable part of the invention, since its composition depends on the water conditions that are needed at each moment, which depend on the animal species, the size, the number of individuals and their metabolic state. . The filter includes filtering material such as perlon and sponges for the retention of the coarsest material. Other materials may also be included, depending on the needs of the organisms, such as materials with a high surface-volume ratio, to favor the establishment of microorganisms capable of converting metabolic (toxic) residues into substances that are harmless to animals. The use of materials such as active carbon, capable of eliminating hormones and some metals, is necessary.

A system for the elimination of proteins and nitrogen compounds can be incorporated into the filter or the reservoir, either by formation of micelles, ozonation or any other means.

The invention describes a filtration system of easy cleaning and handling, with good accessibility to be able to operate on any of the elements included at any time.

The flow of water is forced to pass through the filtering materials by means of a water pump included in the filtration system. This pump sends the filtered water to the aquarium system, which is above the water reservoir. The flow of water will depend on the needs of the system: number of aquariums, animal species, and size of the organisms.

The mill admits the possibility of installing more than one filtration and water pumping system to ensure the operation of the invention in continuous, being able to perform cleaning or manipulation of one of the systems while the mill remains active.

The distribution of the filtered water, coming from the water pump, will be done by coupling the outlet pipe to a distribution piece type "T." Next, a flexible pipe with its two ends coupled to the two outputs is included. free of that piece type "T", leaving the system as a circular pipe, without edges. This closed system allows the maintenance of a homogeneous pressure inside the pipe. The water outlet is produced through several holes, all of the same size to maintain the same output flow for each of them, made on this pipe. The exit diameter of these holes and that of the hoses coupled to them, must be substantially smaller than the pipe from which they arise.

The number of hoses is equal to or greater than the number of aquariums. Valves can be used to regulate the output of these hoses and even stop it, in order to control the water from each individual aquarium Each of these hoses is introduced through the hole in the lid of an aquarium, providing filtered water to the animal inside it.

All the elements of the modular system of the invention are capable of scaling, both in number and in size, to adapt to the characteristics of the organisms to be maintained. The use of common materials, with the premise that they are innocuous for organisms, allows to build a modular structure quickly and with low economic cost.

MODE OF CARRYING OUT THE INVENTION

The system for the maintenance of living aquatic organisms proposed includes:

a) One or more aquariums (1) intended to contain living organisms indefinitely and without physical, chemical or visual contact with other organisms maintained in the same system.

b) A support tank (7) to contain them, which channels the water leaving them to a water reservoir (10).

c) A water reservoir (10) located below the base line of the aquariums (1). d) One or more systems of filtration and maintenance of the physicochemical conditions of water.

e) One or more water pumps (12) that allows to distribute the filtered water and bring it to the level of the aquariums.

f) Water pipes through a system of pipes and hoses to the aquariums individually.

The system can operate in closed or semi-open circuit.

The size and shape of the different elements are optimized to keep several animals at the same time, without hindering access to any part of the system at any time.

a) Aquariums

Each aquarium (1), intended to contain a living organism is independent of the others, and will be placed vertically on the surface of the support tank (7), with the lid up. Each aquarium (1) must be of impermeable material and harmless to organisms. Its walls must be opaque or painted / covered with dark color with ink / safe materials for organisms. The darkening of the aquarium avoids the animal's visual contact with the outside of it. Their measures can be variable depending on the organism to maintain.

The access to the animals inside the aquariums is done by removing the lid (2) of the same. Each aquarium will have a transparent cover (2) to observe the organisms inside the aquarium without having to open the lid.

The opening of the lids (2) allows introducing / removing animals, performing cleaning tasks, feeding, or any other necessary action. On the other hand, this lid (2) must seal the aquarium sufficiently to prevent the animal housed inside escaping. It can be fixed to the body of the aquarium (1) by clamps, flanges, tapes, rope, wire or any other element of union. The cover (2) can also be covered with some type of opaque material that prevents the entry of light into the aquarium.

The cover (2) has a hole (3) for introduction of the water inlet pipe (19).

The cover (2) also has another hole (4) to introduce air / oxygen into the aquarium (1). The aquarium (1) also has water overflow holes (5), located in the upper part of the aquarium. These holes should have a diameter small enough to prevent the escape of organisms.

The aquariums are extracted manually by means of a handle (6) coupled to its upper part, being able to carry out the pertinent manipulations in a more propitious area. The handle (6) fixed to the body of the aquarium allows to lift and move the aquariums (1) independently and comfortably.

b) Support tank

The support tank (7) must be made of waterproof material and harmless to organisms. It will have a variable size depending on the number of aquariums (1) that you wish to incorporate into the system and its structure will be robust enough to support the weight of aquariums filled with water.

The tank (7) has a drain (8) that collects the water that overflows from the aquariums (1), which passes through a pipe (9) that connects the drain (8) with the water reservoir (10).

c) Water reservoir

The reservoir of water (10) is located below the level of the support tank (7) and its size can vary depending on the number of aquariums (1) comprising the system.

This reservoir (10) incorporates elements of filtration and maintenance of the physical-chemical conditions of the water (11).

The system can operate both in closed or semi-open circuit by means of the adaptation of a clean water inlet (17) coupled to the water reservoir (10). In this case, the excess water of the system leaves by overflow (18) of the tank (10), having to take into account this fact to optimize the waste disposal system of the organisms.

d) System / s of filtration and maintenance of the physical-chemical conditions of the water.

The filtration system (11) must contain elements that eliminate water impurities such as traces of animal metabolism (nitrogen waste, hormones, etc.). It can include a skimmer or separator of proteins, an ozonizer, or eliminate the residues susceptible to create micelles with the air through an overflow system (18) (for this last it will be necessary that the complete system is in semi-open circuit , with continuous supply of clean water). The incorporation of materials such as active carbon that remove hormones produced by organisms is necessary. Other filtration materials can be included in this filtration system (11) such as perlon, sponges or materials with a high volume surface ratio (such as arlite or fired clay, among others) to facilitate the establishment of microorganism colonies and convert toxic residues in innocuous elements for aquarium organisms. The size of the filtration system varies according to the number of aquariums and the size / metabolism of the organisms to be maintained. The levels of oxygen are kept high by means of a diffusing stone (16) or element similar, connected to an air pump or oxygen circuit, to facilitate the diffusion of oxygen in the water.

e) Water pump / s

The flow rate of the water pump (12) will depend on the number of aquariums (1) and the needs of the organisms to be contained therein.

The system can be complemented with the duplication of the filtration and water pumping systems, which allows the manipulation and cleaning of one of the duplicates, while the other remains active, without affecting the activity of the system.

f) Set of water pipes

The set of clean water inlet pipes to the system includes:

- A filtered water outlet pipe (13) from the pump (12).

- A piece "T" type (14) to divide the outlet connection of the water pump (12) in two - A pipe or hose (15) that joins the two outputs of the piece type "T" ( 14), whose function is to maintain the pressure of the water along its entire length and has holes equal to each other along its surface for the exit of water from the water pump, which allows to obtain equal flow rates in all the Departures. The number of holes is given by the number of aquariums present.

- Water outlet pipes (19) from the hose (15) to the aquariums (1). Its number is given by the number of holes of exit in (15), as well as by the number of aquariums (1). Its diameter must be substantially less than the size of the hose (15) and slightly lower than the hole in the lid (2) of the aquariums, thus allowing its introduction into the aquarium (1). At some point of these tubes (19) is placed a valve that controls the flow of water output.

Industrial application

This invention allows the maintenance of several aquatic organisms independently of each other, without visual, physical or chemical contact, for an indefinite time.

It allows a scaling of the number and size of aquariums that will depend on the needs of the user and the accompanying scaling of the rest of the elements presented in this invention. It can therefore be applied to the aquaculture industry, whether for maintenance, fattening, or transport of live animals, as well as used in research or education organizations. It is not considered necessary to make this description more extensive to understand the scope of the invention and the advantages derived therefrom.

The materials, shape, size and disposition of the elements will be susceptible to variation, provided that this does not imply an alteration to the essence of the invention.

The terms in which this report has been described should always be taken in a broad and non-limiting manner.
