摘要:
Die Fischreuse ist insbesondere für den Aal- und Krebsfang anwendbar. Es soll bei geringem Material-, Herstellungs- und Wartungsaufwand, reduziertem Transportvolumen, leichter Handhabung und verbesserter Fängigkeit, ein geringer Strömungswiderstand, eine ununterbrochene Spannung des Netzes und ein einfacher Aufbau gewährleistet werden. Erfindungsgemäß wird das dadurch erreicht, daß das Netz ein zylindrischer Quadrat- oder Wabenmaschen aufweisender mittels der ringförmigen Einlaß-, Kehlen- und Stertb-Ogel (1,2,3) sowie Spreizstangen (4), spannbarer Netzschlauch (10) ist, wobei zwischen dem Einlaßbügel (1) und dem Kehlenbügel (2) eine trichterförmige Vorderkehle (8), und zwischen dem Kehlenbügel (2) und dem Stertbügel (3) eine trichterförmige Hinterkehle (2) angeordnet ist und der Ösen (5) aufweisende Einlaßbügel (1) an den Spreizstangen (4) einhängbar ist und der Kehlenbügel (2) und der Stertbügel (3) über Ringe verschiebbar auf den in einem Spreizstangenkreuz (7) zusammengeführten Spreizstangen (4) angeordnet ist, wobei der Netzschlauch (10) an seinem mit einer Stertschnur (6) verschlossenen Ende in dem Kreuzungspunkt des Spreizstangenkreuzes (7) ununterbrochen gespannt gehalten ist.

The invention relates to structure of the collapsible fishing trap (A) that consists of several parts connected with mesh. The collapsible fishing trap consists of the frame made of at least four loosely connected arms. The trap may consists of the frame (B) or the frame (C) . The frame (B) has the main arm (3) with the thread (4) over which there are pulled the loops (2) of the arms (1) , fixed with the nuts (5) . The frame (C) consists of arms with loops that are pulled over bolts and fixed with nuts. The collapsible fishing trap frame is, when unfolded, covered with mesh over all its sides except one opening in the narrower lateral side. In the free opening, the mesh covers lateral sides of the adjacent arms, but leaving the opening (11) in the middle of the frame, through which the fish will enter the trap. When the collapsible fishing trap is unfolded, two arms in the upper The invention relates to structure of the collapsible fishing trap (A) that consists of several parts connected with mash.

The present invention concerns a box-like fish-trap (1) comprising a frame, which is foldable, involved by a net, characterised in that it consists of: - A metallic upper body (2), which floats; - A metallic lower body (3); - Flexible cables (4) to fix the upper body (2) to the lower body (3); - Flexible side nets which connect the lower body (3) to the upper body (2); - Frames (6, 7) that hold the nets of the fish entrance openings (5) and which are arranged so as to let the fish come in but make it difficult for it to get out; and - One bottom (16) formed by a frame and net fixed in an articulated manner to one of the tops of the lower body and closed at the opposite top, which will make it possible to collect the captured fish.
摘要:
The aim of the invention is to establish a colony of and harvest vagile benthic animals, in particular crabs, including on structured and inaccessible beds of bodies of water. To that end, the device (01) according to the invention has either side of a central hinge (06) two auxiliary hinges (11) by means of which frames (03) can be positioned at different opening angles (Θ) of the device (01) such that it can also be adapted to structured beds of bodies of water (02). The device (01) is hoisted and lowered in the collapsed or folded form, and is laid out in the folded or fully open form. Tubular components (15) improve drift and are particularly attractive as a habitat for crabs. The device (01) according to the invention can thus be used as an artificial reef to establish a colony and as a trap for effectively harvesting crabs in the immediate surroundings of wind turbines in offshore areas.
