This paper reported the pollutant removal performances of a hybrid wetland system for the treatment of aquaculture wastewater. The system consisted of two treatment stages: a subsurface vertical flow (VF) wetland, followed by a horizontal flow (HF). The aquaculture wastewater with the different concentrations such as eutrophy and mesotrophy was treated using hybrid constructed wetland. The expe...

In Prince Edward Island (PEI), shellfish (bivalves comprised of mussel and oyster) aquaculture production occurs in sheltered, generally shallow bays. The productive capacity of a bay for shellfish aquaculture is determined by many factors including the hydrodynamics of the bay and input of nutrients. There is considered to be a limit to the production (biomass) that can be extracted from an ar...

Aquaculture is the fastest growing food-producing sector accounting for almost 43% of the world’s food fish. There is however a need to increase aquaculture production in the next two decades in order to satisfy the minimum protein requirement for human nutrition. There are many constraints that limit the maximum production in aquaculture systems such as water quality and adequate live feeds. W...

In Bangladesh, black tiger shrimp (Penaeus monodon; Fabricius, 1798) aquaculture has come to be one of the most important sectors in both the rural and national economies. Likewise, organic shrimp aquaculture has emerged as an alternative farming enterprise for farmers especially in the southwestern districts of Bangladesh. The present study aims to show key performance characteristics of organ...

Aquaculture ranks among the most dynamic food production industries in the world, with an annual growth rate of 9.2% since 1970 [1]. Both the fisheries and aquaculture sectors are facing strengthened regulations, with an emphasis on improving sustainable growth and environmental protection. The New Earth Observation Markets for Fisheries and Aquaculture (NEMA) project has established a number o...

Marine aquaculture is expanding into deeper offshore environments in response to growing consumer demand for seafood, improved technology, and limited potential to increase wild fisheries catches. Sustainable development of aquaculture will require quantification and minimization of its impacts on other ocean-based activities and the environment through scientifically informed spatial planning....

Risk based design uncertainty analysis has also been used on system that use fill materials from seabed, hills, deep underground excavations, and even construction debris, engineers are able to create relatively vast and valuable land from the sea. Aaquaculture industry is one of the fastest growing sectors in the world. Considerable interest exists in developing open ocean aquaculture in respo...

A significant problem hindering the emergence or the continued growth of aquaculture in many marine areas is the conflict that arises among it and other ocean uses. We develop a framework to clarify the choice of the optimal scale of aquaculture when that use impacts a commercial fishery. We identify a range of potential impacts, both positive and negative, and analyze how one or more might aff...

ronmental issues. Despite oversight by U.S. federal and state regulatory agencies and despite sustainability efforts within the aquaculture industry, advocacy groups and the public are concerned about the effects of aquaculture on the environment. Specific concerns include the effects of effluents and nutrient-loading; water, land and energy use; feed composition; drugs and chemicals; and food ...
