Managing overcapacity in small-scale fisheries in Southeast Asia

It is now almost universally accepted that most of the nearshore fisheries in Southeast Asia are overfished. It is also accepted that overcapacity is one of the leading causes of this overfishing. The problem of addressing overcapacity in small-scale fisheries in Southeast Asia is much more complex than that of reducing overcapacity in industrial fleets. In order to manage capacity, managers need to measure and understand how much capacity currently exists in the fishery and what is the desirable level of capacity that best meets the set of management objectives. The only feasible solution to overcapacity may be based on a coordinated and integrated approach involving a mixed strategy of resource management, resource restoration and conservation, livelihoods and economic and community development, and restructured governance arrangements. The reduction of overcapacity implies an increased focus on people-related solutions and on communities.     

Interdecadal variability of anchoveta abundance and overcapacity of the fishery in Peru

Paleontological and historical stock abundance estimates indicate that pelagic fish populations inhabiting upwelling ecosystems undergo large interdecadal variations in abundance with amplitudes equal to, if not larger than, the interannual variability. The interdecadal variability is characterized by periods of high and low abundance, termed “pseudo-cycles”, because of their irregular periodicity. Fisheries targeting small pelagic fish suffer from overall overcapitalization, like many other fisheries, but also from an additional overcapitalization problem: a phase displacement between rapid fish population decreases and a slower disinvestment which follows. This lag produces economic hardship.Here we document the fish:fishery relationship for the Peruvian anchoveta. Anchoveta pseudo-cycles of 20 to >100 years are observed, with the present stock abundance most likely located near upper part of the cycle. Fleet overcapacity expressed as the proportion of unused present capacity is estimated at 72% and processing overcapacity at 89%. A simple bio-economic model demonstrates the risks associated with the pseudo-periodicity in fish stock abundance in conjunction with fishery investment, open access, and overcapacity: a timing bomb for the fishing sector. The lag between disinvestment and decrease in fish abundance is quantified. A reduction of the fishing and processing capacity and measures to decrease the investment lag are recommended to limit the social, economical and political tensions that will result from the expected decrease in stock abundance. Finally, some management options to reduce these risks are discussed.     

An economic analysis of illegal, unreported and unregulated (IUU) fishing: Key drivers and possible solutions

The fight against illegal, unreported and unregulated (IUU) fishing activities has recently become a high priority in the international fisheries management agenda. While a number of academic contributions have sought to improve the understanding of the problem, most remain limited in scope. To help policy makers obtain a more comprehensive picture of the situation, the OECD Committee for Fisheries recently completed a study addressing the full economic dimensions of IUU fishing in an integrated manner. This paper presents the analytical framework developed by the OECD as well as some of the key results of the study regarding the causes of and the potential solutions to this widespread problem.     

Estimating the effects of technological efficiency on the European fishing fleet

By comparing the real reductions in fishing capacity of the European Union (EU) and the effects of technological efficiency, this paper presents the first comprehensive analysis since the creation of the Common Fisheries Policy (CFP). Using a standard methodology and a conservative value of ±4.4% for annual technological progress, the results obtained for tonnage indicated that the EU-13 fleet's fishing capacity was reduced by >4% for only three years (1991, 2004, and 2006) in the 1987–2006 period.     

Managing fishing capacity in tuna regional fisheries management organisations (RFMOs): Development and state of the art

Overcapacity is a major threat to the sustainability of tuna resources. Diverse actions are being carried out by tuna RFMOs to counteract this problem. This paper reviews and analyses both the historical development of fishing capacity management in tuna RFMOs and their state of the art practices. Despite the fact, that thus far, management measures have not yielded the expected results for capacity reduction, they provide a good basis for improved management of capacity at regional and global levels.
