Description

Multifunctional reef squid egg collector

technical field

The utility model relates to a multifunctional artificial fish reef, in particular to a multifunctional fish reef type squid egg collector.

Background technique

Since 2006, the deep-water cage culture of Sepiella maindroni de Rochebrune, one of the “Four Seafoods”, has been carried out along the coast of Zhejiang Province. The direction of development has broad prospects. However, the survival rate of cultured squid is low, less than 50%. The rough methods of recapturing squid make it impossible to supply a large amount of live squid to the market, which has become the main factor hindering the large-scale process of squid farming. At this stage, the squid breeding target is the needleless squid, which has great potential for development, but problems such as low survival rate and low-level recapture technology plague farmers, resulting in loss of wealth. From a biological point of view, in the natural sea area, it lives in the bottom habitat like most cephalopods, likes caves, is prone to inkjet death when frightened, and has strict requirements on the breeding environment. At present, farmers use sunshade nets to cover the breeding water surface to reduce disturbing factors such as sunlight stimulation and seabird attacks. When fishing, they use traditional fishing nets to catch, but the effect is not good. When the water is exchanged in the breeding area, the squid lacks protection and the water flow Factors such as stimulation lead to inkjet, resulting in a high mortality rate. The extensive operation during fishing makes the success rate of live catches low. Most of the cuttlefish supplied to the market are frozen individuals after death, which seriously affects the selling price. At present, squid roe has become a nutritious dish with high market demand, but it is necessary to specially arrange squid spawning attachment reefs to collect squid roe. The above-mentioned problems that perplex the squid aquaculture industry need to be solved urgently.
