Description

COMPOSITE ARTIFICIAL FISH ROE COLLECTOR

TECHNICAL FIELD

The invention relates to the technical field of artificial fish roe collectors, in particular to a composite artificial fish roe collector.

BACKGROUND

Any discussion of the prior art throughout the specification should in no way be considered as an admission that such prior art is widely known or forms part of common general knowledge in the field.

In recent years, due to problems such as human overfishing, implementation of hydropower and water conservancy projects and serious pollution discharges, China's coastal ecosystems have been damaged to different degrees, resulting in a serious decline in the number of fish. In view of this, China has adopted a series of fish proliferation and release activities to maintain ecological balance. However, in the process of practice, it is found that artificial proliferation has certain ecological risks, and it is difficult to ensure the survival of fish that originally survive in nature and after changing the environment of the fish and breeding them in enclosures, and thus the survival probability is very small. Artificial fish roe collectors can provide imitative-ecological spawning conditions for fishes of which the spawning grounds have been distorted, which makes up for the lack of artificial proliferation. However, the existing artificial fish roe collectors are almost exclusively set for fishes laying grass-adhered roes, and the soft adhesive medium needs to be subjected to a series of treatments such as disinfection and soaking in advance, which results in the problems of complicated production and short service life.

Therefore, based on these problems, it is advantageous to provide a composite artificial fish roe collector to overcome or ameliorate at least one of the disadvantages of the existing artificial fish roe collectors designed only for fishes laying
