Description

Increase breeding device for shellfish attached to intertidal zone of island on outer side

Technical Field

The invention relates to the field of marine shellfish culture, in particular to a shellfish proliferation and culture method and a shellfish proliferation and culture device for an intertidal zone of an outside island reef.

Background

The intertidal zone of the island reef area outside the coastal region of southeast China mainly comprises three types of lithofacies, mud facies and sand facies substrates. According to the preliminary investigation, the lithofacies substrate intertidal zone shoreline accounts for more than 60% and the area accounts for more than 50% of the whole intertidal zone. In the several types of intertidal zones, the sand phase and mud phase substrate intertidal zones are basically saturated or supersaturated at present, and the rock phase intertidal zones are almost blank for artificial propagation besides artificial collection resources.

A large number of attached shellfish exist on lithofacies, which are dominant biological groups in low-tide areas in intertidal zones of the reef areas at the outer sides, the attached shellfish are large in reproduction quantity, rapid in growth, strong in adaptability and wide in ecological range, are fixed on an object by bybyssus, cannot move for a lifetime, and are very suitable for cultivation. The shellfish utilizes the gills to filter food such as plankton, organic debris and microorganism in water, and has remarkable clustering phenomenon. For years, along with the cognition of people on the edible value of various attached shellfish, a large amount of attached shellfish resources in the island reef area outside are collected, so that the supplement capability of the attached shellfish resources is lost, and the ecological environment of the attached shellfish is seriously damaged.
