Embodiment Construction

[0031] In order to make the present invention more comprehensible, preferred embodiments are described in detail below with accompanying drawings.

[0032] Such as figure 1 and image 3 Shown, the present invention a kind of catamaran movable farming workboat, comprises the first hull 1 and the second hull 2 ​​that provide main buoyancy with power system and propulsion system, and the number of parallel middle bodies that are arranged between two hulls 3 lifting net cages; the two hulls are connected through the middle deck 41 of the bow, the middle deck 42 of the tail and several truss connection structures 5 in the midship area; the closed circulating water factory culture of small-sized fish is carried out in the two hulls , Relay large-scale adult fish wild farming in lifting cages.

[0033] On the main deck of the first hull 1 and the second hull 2, an external transfer crane 71 and a net cage auxiliary operation crane 72 are installed, all arranged at a position close ...

Abstract

The invention discloses a double-body movable culture work ship. The ship is characterized by comprising a first ship body, a second ship body and a plurality of lifting net cages, wherein the first ship body and the second ship body are oppositely arranged at the side faces of the ship and used for providing main buoyancy, and the lifting net cages are arranged between the first ship body and thesecond ship body and connected with the two ship bodies; and closed circulating water industrial aquaculture of small-size fishes is carried out in the two ship bodies, and wild aquaculture of large-size adult fishes is carried out in the lifting type net cages in a relaying manner. According to the ship, the advantages of a closed culture mode and an open culture mode are organically integrated,and offshore wild culture from the small fries to the adult fishes is achieved. Compared with open type net cage culture, marine culture can be started from the small-specification fish fries, the pressure of land or near-shore net cage culture on the environment is reduced, and meanwhile the marine transportation cost of large-specification fishes is reduced; and compared with full-closed type culture, the ship has the advantages that low-density open type wild culture is adopted in later-stage culture, and the quality and selling price of bred fishes are higher.

Description

technical field [0001] The invention relates to a double-body movable breeding workboat, which belongs to the technical field of aquaculture and marine engineering. Background technique [0002] Affected by the deterioration of the external water environment and the deterioration of internal water quality, the inland and coastal aquaculture space has been squeezed, and problems such as excessive mariculture density, frequent disease occurrence, and environmental degradation have become increasingly prominent. Major aquatic countries in the world are vigorously developing far-reaching Mariculture industry and equipment. At present, deep-sea aquaculture is mainly divided into two modes: open cage aquaculture and closed ship-borne cabin aquaculture. Typical large-scale aquaculture equipment includes "OceanFarm1" semi-submersible cages, Norwegian "Havfarm1" breeding workboats, "Dark Blue 1" "No. 1" full-submersible cage, "Channel No. 1" single-column cage, etc. [0003] Due to...
