Focus groups were combined with surveys to inform policy making regarding precautionary measures to protect cold water coral (CWC). CWC represent complex environmental public goods involving irreversibility and uncertainty. Respondents believe CWC is valuable and should be protected. Use-values, particularly habitat for fish, dominated the focus group discussions, whereas non-use...
This paper develops a count data model of target species and bycatch
production for an arbitrary number of species that handles correlation
between species and over time. The model is applied to a large observer
dataset for fishing trips taken from 1990 to 2008 for roughly 150 vessels
participating in...
Existing research on the effectiveness of marine protected areas narrowly focuses on developing sets of management
indicators tied to outcomes described in management plans or on the achievement of a single objective such as an
increase in the size or number of older, more fecund female fish in a protected...
The aquaculture sector is uniquely placed to complement production from the stagnating capture fisheries sector and it has advantages in terms of controllable production characteristics. However, aquaculture poses undeniable economic, environmental and social challenges that may be poorly evaluated or inadequately addressed within current policy frameworks. In such cases, the...
Combinations of 7 remarkably similar factors have led to the (partial)
failure of recent efforts to address five global or national crises. The paper
analyzes the global financial crisis, climate change, the US health care
crisis, the blue fin tuna collapse in the Atlantic Ocean and the collapse of
fish...
In 1996, the US New England Fishery Management Council formed a
technical team (PDT) to develop a new plan for Atlantic Herring (Clupea
harengus harengus). The inshore stock was close to fully exploited while
the offshore stock was underexploited. There were few full-time herring
harvesters and very few processors. Fresh...
Indian Ocean Tuna fisheries after a rapid development period from
seventies to the end of the last century are faced with challenges including:
the fishing capacity control, the profitability improvement, and the
limitation of impacts on high seas biodiversity. In this area, tuna species
are exploited by coastal states as...
The Pacific sardine fishery is shared but independently managed by three nations: Canada, USA and Mexico. As a result, potential conflict scenarios may arise. A stochastic optimal control methodology is presented to analyze potential conflict scenarios by first considering a deterministic logistic stock growth function and adding a stochastic term,...
Vietnam’s policy is to shift the fishing pressure from onshore to offshore water since the coastal resource has been overexploited, and a programme for investing in offshore vessels has thus been implemented since 1997. The question raised is whether the offshore fishing fleet is profitable and efficient or not? This...
In most of the coastal countries, the fisheries enable to satisfy multiple socio-economic needs such as food safety, public receipts, employment and so on. It is especially true in many coastal developing countries where fisheries constitute a considerable source of food and incomes. However, the strong pressure on the fisheries...
