The sea cucumber (Apostichopus japonicus) is becoming one of the most important fishery resources in Asia. The smooth and gulf cordgrasses have a single spike for its inflorescence, whereas the marshhay cordgrass has 3-5 spikes set off at a 45° from the stem. Spartina alterniflora, smooth cordgrass is a perennial deciduous grass, which is found in intertidal wetlands. Ecosystems , … https://doi.org/10.1016/j.aquaculture.2020.735863. Varieties of plants and animal species live, breed, and forage in the wetlands. A new way for the utilization of the invasive species Spartina alterniflora is proposed. The biodiversity and total density of benthic macrofauna did not change after the restoration of Spartina wetlands with native mangrove species. The response of deposit-feeding animals to plant invasions is still unclear, because their food sources are often difficult to identify.

The higher assimilation of S. alternifl-ora by A. latericea compared with C. larßillierti is The community structure and diet of benthic macrofauna in a Spartina alterniflora wetland and restored native Kandelia obovata mangrove forests of different ages were compared in Zhangjiangkou estuary, China. This study investigated the effects of the addition of S. alterniflora in the diet of juvenile A. japonicus on growth performance, digestive enzyme activity, non-specific immunity and gut microbiota. The results showed that specific growth rates (SGRs) improved with the addition of S. alterniflora, but did not increased with the increasing proportion of S. alterniflora. Some studies have shown that the organic detritus of S. alterniflora can be used by benthic animals. By continuing you agree to the use of cookies. Gao, X.; Wang, M.; Wu, H.; Wang, W., and Tu, Z., 2018. The results of this study indicated that S. alterniflora could be a potential food source for A. japonicus and might be beneficial to A. japonicus growth. January 1994; Marine Biology 118:109-114; Authors: Felix Baerlocher. The cellulase activity was highest in P20 group, which is a mixture of 20% S. alterniflora, 20% S. polycystum and 60% muddy sediment. The addition of Spartina alterniflora is beneficial to the gut microbiota and growth of sea cucumbers. Thus, our results suggested that Père David's deer gut microorganisms potentially coevolved with host diet, and reflected the local adaptation of translocated population in the new environment (e.g., new dietary plants: Spartina alterniflora). Non-specific immune enzyme activity was not altered by the addition of S. alterniflora. Invasive plants strongly affect physical and biotic environments of native ecosystems. In July 2010, an area occupied by S. alterniflora (6.7 hm2) was identified, and subsequently, this inva-sive species were cleared by cutting and waterlogging and replaced Each cow was randomly offered one of the four maintenance rations formulated to incorporate different amounts of S. alterniflora in the diet: 0% (0% SA, control diet), 5% (5% SA), 15% (15% SA), or 25% (25% SA) with S. alterniflora as forage proportionally replacing an equal amount of conventional maize silage and Chinese wildrye hay. The increase in the ratio of S. alterniflora also improved the food conversion efficiency (FCE) of A. japonicus. Spartina alterniflora is native to the eastern coast of North America. Powdered S. alterniflora and Sargassum polycystum were mixed in five proportions (0,100, 25,75; 50:50; 75:25; 100:0) along with muddy sediment (60% of total food) to create five different experimental diets for sea cucumbers.
