In recent years, stock enhancement in Shandong province has been carried out in two ways. One is to release hatchery-reared juvenile . The other is to provide suitable spawning substrates made of salt cedar branches or sweet wormwood branches. The materials for the spawning substrates are cheap, and the substrates are also appropriate for conservation and enhancement. However, the materials can't be reused and are easily damaged on transportation and deployment. Furthermore, successive cuttings of salt cedar and sweet wormwood significantly damage the two terrestrial plant species. Therefore, in order to improve stock enhancement and to further expand the stock enhancement scale, identification of environment-friendly spawning substrates has become an important issue. A study on different types of spawning substrates for oosperm adhesion was conducted in an indoor spawning pool. Additionally, the adhesion of oosperms to the spawning substrates was also examined in the field. The results of the indoor experiment showed that the adhesion of the oosperms on salt cedar branches was the best, followed by that on the cruciform spawning substrates, with that on the sea cucumber frame being the worst. The adhesion of oosperms on the white cruciform spawning substrates was significantly better than on the black ones (<0.05). Attaching salt cedar branches to the cruciform spawning substrates significantly increased oosperm adhesion. In addition, oosperm adhesion on the cruciform spawning substrates, which were placed at the pool bottom, was significantly better than those hung in the upper water (<0.01). In the field experiment, the results showed that oosperm adhesion to the cruciform spawning substrates was good in both 2015 and 2016, with highest oosperm adhesion rates being 82.14% and 56.72%, respectively. Oosperm adhesion was not significantly different between the black and the white cruciform spawning substrates (>0.05). Oosperm adhesion to cruciform spawning substrates that were hung at the sea bottom was significantly better than on those hung near the sea bottom (S. esculenta, resource enhancement and comprehensive protection of the spawning population can be achieved effectively by deploying artificial cruciform and collapsible spawning substrates at the sea bottom in its spawning grounds and in the main enhancement and releasing areas of slack water with depths of 15-20 m.
