Abstract

Die Erfindung betrifft ein insbesondere fuer Gewaesserabsperrungen vorgesehenes stationaeres Fanggeraet, das an ueber die gesamte Gewaesserbreite wirkenden Absperrungen in der Binnenfischerei und auch in der Kuestenfischerei eingesetzt wird. Der Erfindung liegt die Aufgabe zugrunde, mit Hilfe des vorgeschlagenen stationaeren Fanggeraetes die aus den abgesperrten Gewaessern ein- und auswandernden Fische getrennt zu erfassen. Das in der Art einer Kummreuse gestaltete stationaere Fanggeraet ist erfindungsgemaess dadurch gekennzeichnet, dass die parallel zu der als Leitwehr dienenden Gewaesserabsperrung angeordneten Kumms aus einer mit einem dreieckigen Querschnitt versehenen Fangkammer und einer Vorkammer bestehen. An den Kummseiten ist die durch eine Seitenwand der Fangkammer und die Gewaesserabsperrung gebildete Vorkammer mit einer Schuerze versehen. Zwischen der Vorkammer und der Fangkammer ist eine Kehle angeordnet, wodurch das Entweichen der Fische aus der Fangkammer vermieden wird. Eine Vorkehle, die aus einem an der Schuerze befestigten und sich in Richtung der Gewaesserabsperrung erstreckenden Netzstreifen besteht, verhindert das Entweichen der Fische aus der Vorkammer.The invention relates to a particular intended for Gewaesserabsperrungen stationary Fanggeraet that is used on over the entire Gewaesserbreite acting barriers in inland fishing and also in coastal fishing. The invention is based on the object with the help of the proposed stationary Fanggeraetes the in and out of the enclosed waters emigrate fish separately. The designed in the manner of a Kummreuse stationary Fanggeraet is erfindaess characterized in that the arranged parallel to the serving as a Leitwehr Gewaesserabsperrung Kumms consist of a provided with a triangular cross-section trap chamber and an antechamber. At the Kummseiten the antechamber formed by a side wall of the catching chamber and the Gewaesserabsperrung is provided with a Schuerze. Between the antechamber and the catching chamber, a throat is arranged, whereby the escape of the fish from the catching chamber is avoided. A pre-throat consisting of a net strip attached to the apron and extending in the direction of the water barrier prevents the escape of the fish from the antechamber.

Description

embodiments The invention will be explained below with reference to the embodiment shown in the drawings. Show it: Fig. 1: perspective view of the stationary gear Fig. 2: Front view of the fishing gear during the fishing process (a) and when lifting the catching chamber (b).

Entsprechend Fig. 1 gelangen die Fische, von der jeweiligen Gewässerseite kommend, an die Gewässerabsperrung 1. Beim Entlangschwimmen an der Sperre treffen sie auf das Fanggerät. Die Schürze 4 bildet mit dem Pfahl 3 eine schlitzförmige Öffnung, an die sich die Vorkehle 10 anschließt. Das Entweichen aus der Vorkammer 11 ist durch diese Vorkehlen erschwert. Über eine Kehle 5 gelangen die Fische in die Fangkammer 2. Die Unterkante der Fangkammer 2 Ist mit einem Spreizbaum versehen, an dem eine Hahnepot 7 befestigt ist. Zum Besehen der Fangkammer (Fig.2) werden die Niederholer 9 gelöst, und die Fangkammerunterkante wird mit dem Hahnopot 7 gehoben. Die Enden des Hahnepots sind verschieden lang, so daß beim Anheben die gefangenen Fische in Richtung der Entnahmeöffnungen 8 verdichtet werden und boim weiteren Anheben aus diesen herausgleiten.According to Fig. 1, the fish, coming from the respective side of the water, get to the water barrier 1. When swimming along the barrier they meet the fishing gear. The skirt 4 forms with the pile 3 a slot-shaped opening, to which the pre-throat 10 is connected. The escape from the prechamber 11 is complicated by these pre-grooves. The fish enter the catching chamber 2 via a throat 5. The lower edge of the catching chamber 2 is provided with a spreader tree to which a cockpit 7 is fastened. To see the catching chamber (Figure 2), the downhaulers 9 are released, and the Fangkammerunterkante is lifted with the Hahnopot 7. The ends of the Hahnepots are of different lengths, so that when lifting the caught fish are compressed in the direction of the removal openings 8 and boim further lifting out of these.

Das Hebezeug für die Hahnepot 7 kann stationär an einem entsprechend langen Pfahl 3 für beide Fangkammern angebracht sein, so daß ein Besehen des Fanggerätes mit kleinen Booten möglich ist.The hoist for Hahnepot 7 may be stationarily mounted on a correspondingly long pile 3 for both fishing chambers, so that a view of the fishing gear with small boats is possible.

Claims

-1-? 70 Claims:

3. Stationary fishing gear according to claim 1, characterized in that between the antechamber (11) and the catching chamber (2) has a throat (5) is arranged.

4. Stationary fishing gear according to claim 1, characterized in that the lower edge of the catching chamber (2) is provided with an actuatable by a Hahnepot (7) Spreizbaum (6).

5. Stationary fishing gear according to claim 2, characterized in that one of the apron (4) and fixed in the direction of the water barrier (1) extending net strip forms the pre-throat (10).

6. Stationary fishing gear according to claim 1, characterized in that the catching chamber (2) is provided with removal openings (8) for the fish.

Field of application of the invention

The invention relates to a stationary fishing gear provided in particular for water barriers, which is used on inland fisheries as well as in inshore fisheries over the entire width of the water.

Characteristic of the known technical solutions

Stationary trapping gear are known in Forrvvon Bügel and Kummreusen. Upright lintels, which ensure their catchability over the entire depth of the water, require a high technical outlay in terms of their hanger size. Accordingly, the effort in the production and catch extraction. Conventional Kummreusen require a high material usage. For their relief and Abfisu. ^ Ng larger vehicles are needed. Since the Kummboden can flow in rivers by pollution load, a large amount of work is needed to lift. Known types of reindeer are not easy to build on existing barriers. If the guardrail is used as a barrier, the fish migrating out of the blocked waters mix with the dinwandernden in the catching chamber.

Object of the invention

The invention aims to reduce the technical-economic effort to erect stationary fishing gear at water barriers and catch extraction.

Explanation of the essence of the invention

The invention is based on the object to provide a stationary fishing gear in which the incoming and out of the closed waters fish are detected separately. The fixed in the manner of a crawler stationary fishing gear according to the invention is characterized in that the arranged parallel to the serving as Loitwehr Wasserässerabsperrung Kumms consist of a provided with a triangular cross-section trap chamber and an antechamber. At the Kummseiten the antechamber formed by a side wall of the catching chamber and the river barrier is provided with an apron. Between the antechamber and the catching chamber, a throat is arranged, whereby the escape of the fish from the catching chamber is avoided. In order to prevent escape of the fish from the antechamber, a pre-throat is provided, which is formed from an attached to the apron and extending in the direction of the waters barrier Netzstreifen.

Another feature of the invention is that the lower edge of the catching chamber is provided with a Spreizbaum on which a provided with different lengths end Hahnepot is attached. When lifting the catching chamber with the help of Hahnepot the caught fish slide through the removal openings in corresponding transport container.
