Abstract

The present hatchery for raising and keeping crustaceans and fishes has highly modular and compact features, is structurally based on forming a plurality of rectangular and longitudinally juxtaposed modules (1), provided with tight compartments (5), independent to each other, designed to house specimens. The water serving these compartments (5) is continually or periodically renewed, purified and oxygenated, due to the existence of independent ducts for water adduction, oxygen injection and individual channels for residues and organic dejections drainage, allowing thus a complete insulation of waste from each specimen relating to the other ones, in any operational condition, said hatchery further having a moveable feeding device (36), totally independent of the specimen's raising structure, providing, through its insertion into said raising hatchery, a rational provision of nutrients and food to all specimens housed in compartments (5) constituting said hatchery.

Description

Title:HATCHERY FOR RAISING AND KEEPING CRUSTACEANS AND FISHES
The present specification relates to a patent of invention concerning a hatchery for raisins and keeping crustaceans and fishes consisting of compartments independent to each other, wherein each specimen is raised and grown alone until the fattening phase inclusively Concerning this matter the following documents are know.
United States Patent n⍜ A 198.924, which comprises a hatchery provided with several circular basckets. one for each specimen, stacked up and attached to each other through a vertical rod, the basckets being provided with side openings and bottom orifices, the whole assembly being mounted within a vertically cilindrical tank provided with a tubular device designed to control water temperature, PH and flow.
United States Patent n⍜ 3.815.540, which consists of a transparent vertical cilindrical tank having internal racks wich delimit the compartments wherein each specimen will be grown and which are preforated and attached by an axially vertical rod, the whole assembly being provided with a flow system also controlling the water temperature inside the tank,
United States Patente n⍜ 3.916.833, which comprises an aquarium consisting of a tank provided with internal compartments interconnected through orifices located on their side surfaces, wherein a system allows for water flow through the compartments by means of gravity, making the food able to pass through the compartments where the specimens are located, the wastes setting on the aquarium's bottom and being digested by fishes found there; United States Patent n⍛ 4 ∅∅7 7∅9 , which comprises a hatchery consisting of several superposed trays, attached by a central guide, each tray being subdivided in centrally converging compartiments whose walls and floor are provided with orifices that allow for water adduction m these compartments water being neither renewed nor oxygenated.
United States Patent n⍛ 918.B85. which describes an aquarium consisting of a tank provided with cells for housing the specimens, a device for food delivery. an apparatus for oxygen injection and a filter for water cleaning.
United States Patent n⍛ 4 279 218 , which consists of a reservoir provided with several boxes subdivided in four compartiments, one for each specimen, the boxes being stacked up and attached by a vertical rod, there being additionally provided a water flow system along the compartments, and
United States Patent n⍛ 4.559 9∅2, which comprises a reservoir p rovided with tubings and valves to control the hydraulic flow and oxygenation, wherein horizontal plates provided with orifices are disposed, these plates having walls to delimit compartments for housing the specimens
The apparatuses and systems in the above mentioned patents aim the raising of specimens is isolated compartments, however, they present inconvenients that hamper and in-pair the development of said raising, the following being cited.
Although the specimens are kept alone in each compartment, water flowing through several compartments is always the same, bringing about a greater probability of propagating infections which could decimate the raising,
The apparatuses characterised in the above mentioned patents have a low modular structure, especially concerning the housing of specimens, making difficult their handling and access,
Poor visibility of what is happening inside tne compartments, avoiding an easy observation of the specimens behavior and development,
Poor food and nutrients supply, since the same are admitted in a nonhomogeneous way through the compartments, favouring specimes closer to the feeding points and depriving those farther from theses points, net supplying many specimens, and
High amount of man-hour for tasks such as supplying the specimens and maintenance of equipments, rousing operatrional costs and times not feasible in large scale production
In order to eliminate these incovenients, the Patent of Invention entitled Hatchery For Raising and Keeping Crustaceans and Fishes provides a higly modular and compact functional equipment, adapted to large scale production and keeping of specimens, provided with a simple and rapid operation and presenting a high degree of efficiency
This invention intends to eliminate the risk of propagating infections since, besides the water being continually or periodically renewed, purified and oxygenated, organic residues and waste water are prevented from being transfered among the compartments, in view of the compartments tight character An object of the present invention consists of the equipment versatility which makes possible an easy adaptation of modules, increasing the number of compartments and evidently production increases
Another object of the present invention is that it does not need specific installations nor an appropriate ambient to mount the equipment, since the same might be installed in open or closed spaces, sheds and even at home
The invention also provides an easy access to any individual compartment, either for handling or feeding, not needing to displace or move the compartment structure.
It is also an object minimising operational costs and times, making the raising of crustaceans a simple and economical activity, adapted to microprodution on large scale production and providing a price fall in the fish, crustacean and especially prawn market
