Oyster Reefs at Risk and Recommendations for Conservation, Restoration, and Management
Native oyster reefs once dominated many estuaries, ecologically and economically. Centuries of resource extraction exacerbated by coastal degradation have pushed oyster reefs to the brink of functional extinction worldwide. We examined the condition of oyster reefs across 144 bays and 44 ecoregions; our comparisons of past with present abundances indicate that more than 90% of them have been lo...
متن کاملGenetic characterization of great sturgeon brood stocks- recommendations for the conservation management and aquaculture
The great sturgeon, Huso huso, is one of the most important cultured sturgeon species in Iran, which effective management of aquaculture production of this species requires knowledge of broodstock structure, mating patterns, and genetic diversity of broodstock. The aim of the present study was the application of microsatellite DNA analysis for genetic diversity assessment in the first generatio...
متن کاملIndigenous knowledge of flood management and floodwater spreading in Qazvin traditional garden; deserves a new look at conservation and restoration
In arid and semi-arid regions of the world including Iran, floodwaters are the main resource to supply irrigation water. Floodwater spreading also plays an effective role in replenishing groundwater, stabilization of alluvial soil, and vegetation restoration. Qazvin traditional garden is an example of such floodwater spreading mechanism, dating back to over a thousand years ago, according to hi...
متن کاملAn ecosystem approach for oyster restoration and management
In addition to supporting a harvest, the eastern oyster (Crassostrea virginica) in Chesapeake Bay provides ecosystem services such as removing seston, enhancing water clarity and creating benthic habitat. Our objective was to create a flexible ecosystem-based decisionmaking tool to support oyster restoration and management. This Oyster Restoration Optimization model (ORO) incorporates predictio...
متن کاملOyster Demographics in Harvested Reefs vs. No-Take Reserves: Implications for Larval Spillover and Restoration Success
Fishery species that reside in no-take, marine reserves often show striking increases in size and abundance relative to harvested areas, with the potential for larval spillover to harvested populations. The benefits of spillover, however, may not be realized if the populations or habitats outside of reserves are too degraded. We quantified oyster population density and demographics such as recr...
