Abstract
An enclosure construction for fish breeding which comprises two rows of rectangular fish enclosure frames (10) coupled together, which are each constructed of longitudinal and transverse frame members (11-14) and mutually connected to each other via horizontal pivot bearings by way of certain of the frame members which are common to two or more frames (10). A central longitudinal frame member (11) which is common to frames (10) adjoining in pairs is connected at the ends to a joint point-forming frame member (14) which in addition to fastening the central longitudinal frame member or a pair of central, longitudinal frame members (11) also forms a fastening for transverse frame members (13) at a distance outside the central, longitudinal frame member (11). The joint point-forming frame member (14) is in addition to being fastened to the central, longitudinal frame member (11) via a horizontal pivot bearing connected to the central, longitudinal frame member (11) lock at the outer end of a framework (22) at a distance laterally outside length sides of the joint point-forming frame member (14).
