Raft frame device set for sea area breeding of sargassum fusiforme embryos

Abstract

The invention provides a raft frame device set for sea area breeding of sargassum fusiforme embryos. The raft frame device set comprises two channel cables, at least two raft poles and at least one culture medium group, the raft poles which are fixedly arranged side by side are located between the channel cables, the culture medium groups are connected between the neighboring raft poles, and the raft poles are closed pipes which are elastic, tough and capable of floating on the surface of the sea area; fixing fittings for connecting a plurality of culture medium cotton tapes integrally are respectively arranged at two ends of each culture medium group, a connecting cotton tape is arranged between the fixing fittings and the raft poles and are circumferentially rotatably arranged relative to the raft poles, the connecting cotton tapes are arranged in two sections and include the first connecting cotton tape and the second connecting cotton tape, corresponding ends of the first and second connecting cotton tapes are connected through cotton tape connectors, and the cotton tape connectors include the first cotton tape connector and the second cotton tape connector which are respectively detachably connected at the ends of the first connecting cotton tape and the second connecting cotton tape. The raft frame device set is suitable for multiple sea areas so as to meet modern breeding of the sargassum fusiforme embryos.

Description

technical field [0001] The invention relates to a raft frame device set for mariculture. The raft frame device set is used for stocking the embryos of large seaweed (such as hijiki and sagebrush) in seawater culture. Background technique [0002] Raft culture is generally used in mariculture on the culture medium of hijiki, sargassum and other algal plants. Hijiki is a dioecious algae. According to its developmental stages of life history, the order is: gametes , embryo, young sporophyte, sporophyte and mature sporophyte, after artificial seedling, the hijiki at the embryo stage is placed on the sea surface in the form of a medium tape, and after a period of stocking, a corresponding formation is formed on the medium. Young sporophytes are then transferred to the next growth environment until they become mature sporophytes. [0003] The raft frame device in the prior art is too primitive, including at least two bamboo poles fixed side by side on the channel cable, and the t...

Problems solved by technology

[0003] The raft frame device in the prior art is too primitive, including at least two bamboo poles fixed side by side on the navigation cable, and the two ends of each bamboo pole are respectively fixedly connected to the fixed navigation cable in the sea area, so as to realize the fixing of the bamboo poles. A culture medium group is set between two adjacent bamboo poles, and the culture medium group includes multiple culture medium cloth belts arranged side by side, on which are the hijiki embryos. Otherwise, the hijiki embryo will die due to the lack of sunlight; the two ends of the medium cloth belts arranged side by side are connected by rods to form a medium group, and the two ends of the medium group are connected to the Bamboo poles, in the production process, each culture medium cloth tape is first tied to the pole-shaped object, and then the cloth tapes are tied to the bamboo poles so that the culture medium group is fixedly connected to the bamboo poles, but in the process of artificially tying the cloth tapes, there will be The connection between each medium group and the bamboo poles is inconsistent, resulting in uneven stress. When encountering wind and waves, the tightly connected cloth belts are prone to breakage

In addition, bamboo poles are soaked in seawater for a long time, which is easy to rot and break, which is not conducive to recycling
