Coastal zone sea area oyster larva enhancement and releasing adhesive substrate device and building method

Abstract

The invention relates to a coastal zone sea area oyster larva enhancement and releasing adhesive substrate device and building method. The building method comprises the combined adhesive substrate material selection and manufacturing method, the adhesive substrate seed-adhering technology, the building method of an adhesive substrate suspension breeding device, and the like. The method is characterized in that the rubber tire and oyster shell combined adhesive substrate which is portable, resistant to corrosion and low in cost is developed, and a manufacturing and building method of the adhesive substrate suspension breeding device which can resist stormy waves and improve the survival rate of oyster larvae is provided. The coastal zone sea area oyster larva enhancement and releasing adhesive substrate device and building method are successfully applied in enhancement and releasing of the high-suspended-sediment coastal zone sea area at Yangtze Estuary, the survival rate and adhesive rate of the oyster larvae are improved, the adhesive substrate and the suspension breeding device can resist large stormy waves, and the maintenance cost is low. The coastal zone sea area oyster larva enhancement and releasing adhesive substrate device and building method have the advantages of being easy and convenient to operate, popular and easy to understand, good in effect and the like, can improve the yield of oysters, also achieve the functions of water purification and biological diversity of the conservation water area, have good generalizability, and also have high feasibility in enhancement and releasing of other oyster varieties.

Description

technical field [0001] The invention belongs to the technical field of proliferation and release of oyster larvae, and in particular relates to a fixation base device and construction method for proliferation and release of oyster larvae in coastal sea areas. Background technique [0002] Oyster is a plankton-eating benthic animal, which is attached and lives in groups. The oyster reef ecosystem formed by it has important ecological functions and values. It plays a very important role in the substrate and the promotion of nutrient circulation, and is a good release species in the field of proliferation and release and ecological restoration. With human activities seriously destroying the original oyster reef system in the coastal zone, the oyster reef habitat in coastal zones or bays in China and the world has been gradually subsided by environmental pollution, reclamation and other engineering activities to varying degrees, thus making the estuary or coast The degree of eu...

Problems solved by technology

Generally, in the estuary or coastal zone, the sediment deposition rate is relatively high. If the suspended sediment in the water deposits on the oyster anchorage base, it will bury the oyster larvae so that they cannot grow and breathe normally, resulting in the death of the oyster. Therefore, it is necessary to design a new Oyster larva fixation base device and multiplication release construction method to solve this problem

In addition, the traditional trellis hanging oyster technology is generally carried out in the low tide area of ​​the intertidal zone, it is difficult to reproduce and release in the deep water area of ​​the subtidal zone, and the cost is relatively high
