Shellfish farmers make their production decisions in an environment characterized by multiple
uncertainty. As shellfish farming is done in an open area, producers face a large number of risks:
e.g. biological, environmental, pollution or climatic risks. Historically, this sector has been
affected by several crisis; the last ones were the...
Aquaculture investments in virgin situations are subject to a large number
of variables and range in values. This is even more so when considering
investments in open ocean aquaculture.
The paper presents the key factors and results obtained for a proposed
large-scale open ocean aquaculture development in Western Australia with...
The Mediterranean finfish aquaculture is strongly represented from the successful industrial development of the mass production of the Mediterranean seabass (Dicentrarchus labrax) and seabream (Spaurus aurata), with Greece as the major producer country, contributing with approximately 57% of the global farmed production of both species. Despite the difficulty to obtain...
The aquaculture industry in the UK has experienced substantial growth in
the past two decades. The productivity and competitiveness of the sector to
a great extent depends on the favourable health status that the sector enjoys
relative to other major salmon producing countries in Europe. Currently the
UK is subject...
The present study uses normalized profit function and adaptive expectation approaches to analyze U.S. catfish farm supply. Empirical estimations give short-run supply elasticity of 0.25 and 0.26 and long-run supply elasticity of 0.47 and 2.1 in each of the two approaches, respectively. Technological improvement is attributed for only 9.8% out...
Mussel farming as an aquaculture activity based on the natural primary productivity, faces risks similar to those of the agriculture sector. Consequently, much theoretical risk research has been applied to aquaculture as in agriculture, livestock, forestry, conservation and its management. Nevertheless, limited studies have so far focused on risk perceptions...
Australia’s western rock lobster fishery is its most valuable and hence from a biological perspective most tightly managed major commercial fishery, yet it has been beset by problems of miniscule recruitment over the past 3 years. This coming year 2010-11 is little better. It was the joint first Marine Stewardship...
A major simplification in bioeconomic models is that the model parameters
and functional forms are assumed known. In fisheries, the failure to capture
model uncertainty can easily cause overconfidence in model outputs and
resultant policy recommendations. Although fisheries modelers regularly
assume rather complete knowledge of the systems they study, in...
It is implicitly several economists point out that there is a relation between
remuneration system and the economic performance. However, in my
knowledge, none of them examines how these payments affect on the
economic performance of fisheries. This study is an empirical study
analyses the impact of remuneration system on...
