Embodiment

[0018] Example: refer to Figure 1 to Figure 3 Man's needleless squid net cage cultivation special net cage device, including a floating frame 1 composed of an inner floating frame 11, an outer floating frame 12, a handrail 13 and a connecting bracket 14 and a net clothing 2 arranged on the floating frame 1. The feature is: the inner floating frame 11 is provided with a rope 3; the rope 3 is provided with an attachment rope 31 in the gap. With this structure, in natural sea areas, even if no large algae or filter-feeding shellfish are artificially arranged on the attachment rope 31, since the attachment rope 31 is soaked in water, the surface will naturally adhere to the attachment organisms such as barnacles, mussels, and enteromorpha. Make the attachment rope 31 produce a kind of function similar to the artificial fishing reef, which can adjust the micro-ecological environment inside the net cage.

[0019] The ropes 3 can be arranged radially or reticularly or in parallel. ...

Abstract

The invention discloses a method for culturing sepiella maindroni in a mesh cage and a special mesh cage device thereof. The device comprises a floating frame consisting of an internal floating frame, an external floating frame, a handrail and a link bearing, and a floating web arranged on the floating frame. A boom rope is arranged on the internal floating frame; and attached ropes are alternately arranged on the boom rope. The method comprises the following steps: adopting the sepiella maindroni special mesh cage device as a culture device to culture sepiella maindroni; and placing macroscopic algae or filter food shells on the attached ropes so as to shade the light and improve the internal ecological environment of the mesh cage. The method and the special mesh cage device thereof have reasonable structure, convenient operation and high economical efficiency, bring about the good culture water body ecological environment and facilitate the growth of sepiella maindroni. The method and the device solve the problems of low product quality, worse taste and high culture cost.

Description

technical field [0001] The invention relates to a method for cultivating aquatic products and special cultivation equipment thereof, in particular to a method for cultivating needleless cuttlefish in a cage and a special cage device thereof. Background technique [0002] Mansoni squid was once one of the four major fisheries in my country's fishing grounds. It has strong adaptability to temperature and is widely distributed in my country's coastal areas. It is a traditional fishery species with high economic value. Due to overfishing and ecological deterioration, since the 1970s, there have been declines. At present, the number is very small, and it is only used as bycatch. What prior art mainly takes is factory culture to the squid of mansoni. The factory farming method can make full use of the breeding space, and raise a large number of squid in a short period of time to meet the market's demand for squid, thereby obtaining higher economic benefits. However, because thes...
