Change, transformation and adaptation in recreational fisheries

Change constitutes a fundamental property of all recreational fisheries; it is inevitable. To maintain and continuously develop recreational fisheries adaptation is pertinent. This involves adapting to ecological as well as social, economic or policy changes. What are the conditions that help a recreational fishery to successfully adapt to change? What are the factors that constrain or impede change? This conference is meant, above all, to provide the scientific and practical experience to answer change and adaptation-related questions, both from a social and natural scientific perspective. Such knowledge is particularly relevant for countries in economic development where rapid increase in recreational fisheries is expected to meet with substantial ecological and social changes on short time scales.


The main purpose of the 7WRFC is to foster productive dialogue among all stakeholders envolved with recreational fishing in order to promote sustainability science all over the world. To carry out that dialogue, the organizers emphasize and assume the following scientific principles: holistic/integrative approaches to investigate the problems related to recreational fisheries; interdisciplinarity to analyse phenomena related to recreational fishing; and apropriate communication and information to facilitate the understanding of scientific outcomes among professionals and recreational fishermen.

I. Social and environmental changes and its impacts in recreational fisheries
Recreational fisheries as integrated systems. Fish populations of today’s world. Climate change. Preservation and renewal of stocks. Fish vulnerabilities. Measures to combat environmental harms and hazards (rehabilitation policies and actions; harvest regulations). Place of recreational fishing amongst competing demands.

II. Transformation and maximization of social and economic benefits generated by recreational fishery activities
Economic valuation. Societal benefits: poverty alleviation and livelihoods. New technologies. Communication networks among practitioners. Policies and regulations. Management approaches to sustain recreational fishing. Angling tourism.

III. Recreational fisherman’s attitudes to cope with the impacts of change
Environmental and aquatic stewardship. Conservation and enhancement of aquatic systems and biodiversity. Ethical conducts; codes of conducts. Responsible fishing. Angler’s behaviors towards ecological sustainability.


IV. Technological innovations in the recreational fishing area

V. Catch-and-release practices: novel insights

VI. Innovative management and governance methods in the recreational fishing area

VII. Research on angling diversity around the world

VIII. Minimum and maximum size for catches: policies and regulations


IX. Southern Hemisphere Recreational Salmonids Fisheries

Coordination – Michel Dedual, New Zealand
E-mail – mdedual@doc.govt.nz

Angling is a way of life for millions of Kiwis, Australians, Chileans, Argentineans, and South Africans. Recreational and subsistence salmonid fisheries are big business in these countries where angling tourism is the economic backbone in many regions. Trout and salmon were introduced in Southern Hemisphere waters during the last two centuries and now provide angling opportunities, many among the best in the world. Given the effects of the current global economy landscape and climate change, Southern Hemisphere salmonid fisheries, like their counterparts worldwide, are facing a long list of major threats. Freshwater fisheries are exposed to increasing water demand, pollution, exclusive capture, aquaculture, introduction of exotic species, impacts on native species, and animal extremist movements. The positioning of Brazil in the Southern Hemisphere provides a unique opportunity for encouraging Chilean and Argentinean fisheries professionals to attend this workshop. This will enable us all to learn and share our experiences, and serves as an opportunity to develop a solid network of contacts.

Potential sub-themes:

  • Communication between scientists, managers, and anglers
  • Angling tourism, transfer of invasive species
  • Sharing fairly with commercial fishing/aquaculture
  • Recreational and subsistence fishing: same management?
  • Put-and-take v. self-sustained recreational fisheries
  • Trophy fisheries
  • Catch-and-release
  • Fish welfare
  • Water use/allocation and fisheries protection 



Coordinator: Dr. Agostinho Carlos Catella (Doctor in Freshwater Biology and Inland Fisheries from INPA/UFAM, Manaus – Brazil)

Fishery resources are renewable and can be used without harming the environment, respecting the capacity of stock replenishment. It is a very delicate ethical matter to decide on the use of fishing resources, since society has not invested in its production, not making sense favoring some sectors over others. The best ethical attitude, and that better competes for the conservation, is the enjoyment of the plural of fish resources by different sectors of society. This workshop intends to describe and to deepen, through research results and discussions, those resources.


Morning period: presentation of oral communications that will be submitted for the theme the workshop. The time allotted for each presentation will depend on the number of submissions, not to exceed, however, 20 minutes each.

Afternoon period: Roundtable on the theme of the workshop, including the coordinator plus three guests, having 30 minutes for each presentation, plus 30 minutes for the debate.

Product of the Workshop: preparation of a final document containing a summary and recommendations on the subject.

XI – Assessment of the Economic Importance of Recreational Fisheries

Coordinator – Dr. Kátia de Meirelles Felizola Freire (Federal University of Sergipe, Brazil)

The objective of this workshop is to provide an opportunity for all attendees to learn about initiatives worldwide on the assessment of the economic importance of recreational fisheries and share experiences on successes and challenges observed during the process. We hope this workshop inspires scientists from economies in transition to work on this very important issue and discuss some strategies that allow for future comparison among countries using similar methodologies but at the same time respecting local needs.

XII – Sustainability Sport Fishing of Billfish off Southwestern Atlantic

Coordinators – Dr. Alberto Amorim (Instituto de Pesca, SP) and Dr. Eduardo Pimenta (Universidade Veiga de Almeida-UVA)

Concerned with the decline of billfish catch per unit of effort-CPUE anglers of yacht clubs and the marlin project coordinators, created the Environmental Preservation Campaign of Billfish, in January 2010, in Iate Clube do Rio de Janeiro in Cabo Frio, RJ. The main lines followed were: diagnosis of sport and commercial catches; rescue of CPUE historical commercial and sport fishing; research reproduction, growth and migration; environmental education for children of commercial fishermen; and explanation of the prohibition on sale of blue and white marlin. The ONG Vivamar was chosen to manage the resources received from donations and the sale of the book “Billfish of the Atlantic”. Every year the group of researchers holds meetings to present the progress and discuss the future of the project.

Two-hour presentation (5 guests), followed by debate.
