John Lucas introduces aquaculture, the cultivation of aquatic organisms and its role in human food production for a sustainable future.
This article analyzes spatial and temporal changes of aquaculture land use in Yunlin County, Taiwan, and discusses the driving forces for these changes. Digital land-use maps and satellite imagery for 1982, 1988, 1994, and 2002 were used to extract aquaculture areas. A geographic information system was used to derive changes in aquaculture areas and to compute the spatial clustering statistics ...
Twelve per cent of the world’s population is currently securing their livelihood partly, or fully, through the fisheries and aquaculture sector (FAO Fisheries and Aquaculture Department, 2016). Most people occupied in this sector rely on wild catches; however, fish stocks are becoming depleted with 90% of stocks being fully or overexploited (FAO Fisheries and Aquaculture Department, 2016). A mo...
In the 21 century, aquaculture developers will need to spend as much time on technological advances coming to the field as they do in designing ecological approaches that clearly exhibit stewardship of the environment and coastal societies. The degraded state of aquatic ecosystems worldwide, combined with public concerns about adding new sources of pollution to already overburdened aquatic ecos...
most specialists in the field of foreign language teachingconsiderreading skill as an interactive process between the reader’s prior knowledge and the text.accordingly, the activation of prior knowledge for an effective comprehension is very important. it is generally agreed that the pre-reading phase is the stage where this type of interaction and activation may be enhanced throughcertain stra...
Aquaculture is one of the fastest growing food production sectors and has great potential for security livelihoods. However, it generates concerning consequences environment, including chemical biological pollution, disease outbreaks, unsustainable feeds competition coastal space. Recent investigations are focusing on sustainable techniques (e.g., polyculture, offshore facilities) to improve re...
The growing consumption of aquaculture products requires always new techniques to increase the production yield. Generally, the intensification of aquaculture practices is associated with a stress level rise of bred fishes. Sensitivity to stress, leading to disease, reduced growth and mortality, is higher in larvae than in adult fish. The stress induced effects can be reduced acting on opioid r...
Infectious diseases are economically detrimental to aquaculture, and with continued expansion and intensification of aquaculture, the importance of managing infectious diseases will likely increase in the future. Here, we use evolution of virulence theory, along with examples, to identify aquaculture practices that might lead to the evolution of increased pathogen virulence. We identify eight p...
Aquaculture is the fastest growing food-producing sector in the World, especially, in P. R. China. In the ongoing process of Internet growth, a new development is on its way, namely the evolution from a network of interconnected computers to a network of interconnected objects that is called the Internet of Things (IoT). Constructing an affordable, easy-to-use, aquaculture information system ba...
& This study presents a framework for analyzing the interactions between aquaculture and capture fisheries in the context of ecosystem-based management. We extends a model of the economic and ecological systems in coastal New England by incorporating an aquaculture sector in a computable general equilibrium (CGE) model and by examining the forage fish and aquaculture link in a marine food web. ...
