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 ...
An overview of the current scientific knowledge available on climate change implications for fisheries and aquaculture is provided through three technical papers that were presented and discussed during the Expert Workshop on Climate Change Implications for Fisheries and Aquaculture (Rome, 7–9 April 2008). A summary of the workshop outcomes as well as key messages on impacts of climate change o...
In this report we present a comparative study realized on different aquaculture water samples collected from several fish farms in Tunisia. For each water sample, significant physiochemical parameters such as conductivity, pH, NH4 + , Na + , Ca 2+ , F and NO3 were determined using a potentiometric multi-sensor system named "electronic tongue". Experimental analysis data were standardized and su...
Alterations to the structure of the fisheries industry have become necessary in Japan due to low levels of capture fisheries production, an aging population, environmental concerns, and increased worldwide demand for marine food products. In accordance with these developments, the Fisheries Agency, Ministry of Agriculture, Forestry, and Fisheries, established the new Basic Plan for Fisheries in...
