Definitions

  • This invention refers to an apparatus for fish counting, specifically a modular device being adaptable to several tank sizes for counting fish at different growth stages.
  • Patent US8651057B1 describes a photographic counter for photographing, counting and recording the date and time of any small aquatic animal passing therethrough, including invertebrates, amphibians, reptiles and small mammals, using an aquatic animal passage system, in clear or turbid water storage dams.
  • a drawback associated to this type of devices for fish counting is that, although these solve the problem of the manual capture, the photographs taken in turbid water may not be clear, interfering with the animal identification and body size estimations, which directly affects counting thereof.
  • our invention allows realizing a fish counting in water bodies, since optical sensors are not employed, the performance of which are affected by the water turbidity.
  • the present invention refers to a device for counting fish in the water, being either transparent or turbid, by means of a modular mesh capable of adapting to different tank sizes and shapes.
  • This mesh comprises a great number of windows being adjustable to different fish sizes.

  • FIG.1 shows a fish counting module (1 ) capable of recording, automatically, the number of fish passing therethrough. It has modularity characteristics with the purpose of interconnecting to other modules and thus adapting to different tank dimensions and shapes.
  • the structure (2) of the module is made of an insulating type material that allows insulating the different electric connection comprising: it also has a connector (3) that allows energizing the electric circuits and obtaining the recorded counting data.
  • Each counting module (1 ) comprises several windows (4) capable of counting the fish when these go therethrough, by using ultrasound sensors (4a) installed in each of the windows.
  • interchangeable meshes (5) are used having different sizes and which can be embedded into the fish counting module.
  • the device can be adapted to multiple tank relieves, by using fins (6a, 6b, 6c) placed at the side and bottom ends of the structure (2).
  • the device of the invention uses a control sub-module (7), receiving the data from each ultrasound sensor (4a) located at each window (4) of the fish counting module (1 ), by means of a power and data communication cable (8).
  • This control sub-module (7) is interconnected with a computer so as to send the collected data thereto.
  • FIG. 2 shows some interchangeable mesh (5) models. These mesh models (5a, 5b, 5c) may have several window sizes (9a, 9b, 9c) according to the maximum size of the fish intended to be counted.
  • FIG.3 shows a fish counting module (1 ) working inside a tank (10). In this application the device moves through the tank using a rail (1 1 a) and bearings (1 1 b) system. The fish are forced to pass from one end of the tank to the other, through each window (4) of the counting module (1 ).
  • FIG. 4 shows one of the windows with fish counting sensors.
  • Each window (4) is provided with an ultrasound sensor (4a) that sends an ultrasound wave being reflected by each fish passing through the window, and thus its passage therethrough is computed.
  • These windows (4) are electrically interconnected by means of pipelines (12), embedded in the structure of the device (1 ).
  • FIG. 5 shows possible interconnections of the fish counting modules 1 .
  • These modules (1 ) can be interconnected in several ways: one next to the other (13a) and also one above the other (13b). In this way, the coverage area may be widened both horizontally and vertically, so as to satisfy several sizes of the water bodies.
  • FIG. 6 shows a circular tank. It shows the fish counting module (1 ) working in a circular-shaped tank (14). A central axis (15) allows the module (1 ) to move in a circular movement. The retaining wall (16) is used so as not to allow double counting of the fish.

Abstract

L'invention concerne un dispositif de comptage de poissons à différents stades de croissance, dans des réservoirs de tailles et de formes différentes. Ce dispositif est formé par un maillage modulaire adaptable à différentes tailles de réservoir. Ce maillage comprend un grand nombre de fenêtres et peut effectuer un mouvement linéaire ou circulaire, en fonction de la forme du réservoir. Des capteurs à ultrasons sont agencés dans chaque fenêtre, enregistrant et communiquant avec une station centrale chaque fois qu'un poisson passe à travers la fenêtre, ce qui permet de compter le nombre de poissons.
