& 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. ...
Efforts are on the way on the Swedish West Coast to develop the capacity for cultivation of marine resources, notably of kelps. Given that this is a region of great natural and national heritage, public opposition to marine developments has been identified as a possible risk factor. This survey thus sought to shed light on awareness levels, perceptions of different types of aquaculture and on r...
Abstract This paper focuses on the effect of porosity nets flow field inside deep-sea aquaculture cage. Based CFD method, 2D fields and surrounding cage from different views are simulated. The effects certain net variable with configurations fishability area, efficiency benefit investigated. results showed that suitable in vertical direction can increase area change be conducive to improving fi...
15 The influence of sea-cage aquaculture on wildfish assemblages has received little attention 16 outside of Europe. Sea-cage aquaculture of finfish is a major focus in South Australia, and 17 while the main species farmed is southern bluefin tuna (Thunnus maccoyii), there is also an 18 important yellowtail kingfish (Seriola lalandi) industry. Yellowtail kingfish aquaculture did 19 not appear t...
Aquaculture management authorities require the ability to identify the farm of origin for escaped fish. Physical tagging is routinely conducted for domesticated animals (e.g. sheep and cattle); however, there are considerable logistical, animal welfare and economic issues that challenge the feasibility of physically tagging all farmed fish. A ‘DNA stand-by method’ for identification of escaped ...
The double-crested cormorant (Phalacrocorax auritus) has undergone population expansion throughout much of its historical range since the 1970s, resulting in increased pressure on foraging habitats including real and perceived competition with commercial and sport fisheries and impacts on the aquaculture industry. The specific objectives of this study were to determine the stable isotope ratios...

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...
