TABLE OF CONTENTS Conference information 2 Campeche Convention Center XXI 4 Program at a Glance 5 Program 6 Abstracts Plenary Conferences 15 Theme 1: Assessment of Fisheries Impact 23 Theme 2: Environmental Dynamics 51 Theme 3: Biological and Ecological Indicators 73 Theme 4: Models as Tools for Fisheries Management 95 Theme 5: Integrated Management 109 Author´s index 131 ICCE 2006 About the Conference Conference Infromation Throughout the world there is a growing commitment to the conservation of coastal ecosystems, such as bay systems, lagoons and estuaries, because of their widely recognized social, cultural, economic and ecological importance. Most of these systems have been degraded, however, through pollution, fi shery and habitat destruction, and it is imperative to fi nd ways for their sustainable use, conservation and/or restoration. Fisheries development has until recently focused on the technical improvement of fi shing gears and vessels, fi sh detection and positioning systems as well as on fi sh processing. In most cases the effective fi shing power has increased and stocks are being pushed beyond their optimal harvest levels. Overfi shing is not the only threat to these ecosystems, however. Climate variation and global warming together with extreme weather events (hurricanes, heavy rains) are additional factors impacting these ecosystems and their resources. Economic factors (market prices for fi shing targets, subsidies given to the fi shermen by the government among others) as well as regional management policies such as quota, closed seasons, no take areas, communal management regulations etc.) add to the complexity of the issue of sustainable management of these systems. It thus clearly appears that we need more integration and to move towards an ecosystem approach for fi sheries (EAF). We need to elaborate operational frameworks, to develop integrative approaches at the ecosystem level, and to defi ne innovative reference points to bridge scientifi c results with society’s needs. The conference will contribute to: • Present scientifi c evidence of recent trends and impacts of EAF on estuarine, coastal lagoon and shallow bay fi sheries management. • Review existing knowledge and quantitative tools to further develop integrative approaches for the assessment of the exploitation level and health status of coastal ecosystems. • Evaluation of current management measures of living aquatic resources, considering the impacts of natural changes and human activities on these. Themes 1. Assessment of fi sheries impact. Assessment of the impacts of fi shing on exploited and unex- ploited components of the ecosystems based on the analyses of fi sheries parameters (fi shing effort, CPUE, yield ) 2. Environmental dynamics. Linkages between environmental processes (tidal fl ow, river discharge, etc.) and fi sh resources with a quantifi cation of climate change or environmental variability and their biotic effects, (e.g. regime shifts) as well as the quantifi cation of habitat modifi cation in- duced by fi sheries and/or other anthropogenic sources. 2 Campeche, Campeche. Mexico. June 26 - 29, 2006 About the Conference ICCE 2006 3. Biological and ecological indicators. Selection or building of integrative indicators in order to evaluate and monitor the “integrity” of coastal environments, at the population, community or ecosystem levels. Special attention will be paid on indicators synthesizing the structure and the functioning of these ecosystems over time and space. Comparative approaches will be particularly considered, as will be the effects of different factors on these indicators (e.g. fi sheries vs pollution or fi sheries vs climate or a combination). The session will consider how the indicators have been or should be applied to different types of littoral ecosystems or fi sheries. This could be addressed from a population to a community level approach. 4. Models as tools for fi sheries management. Application of fi sh-based models to estuarine and coastal lagoon fi sheries management issues. IBMs and ecosystem-based models will be used for testing ecological theories in this particular context. The session will also consider suitable what approaches would be suitable for the validation of models. 5. Integrated management. Strategies and measures to be developed to mitigate the threats and to avoid environmental crisis. This includes policy options for a better conservation of aquatic biodiversity, management and conservation, parks and protected areas, legislation to review or reinforce, technical solutions including marketing and business, awareness, public education. ORAL PRESENTATION. The language of the symposium is English, however oral presentations could be in English or Spanish. Inerpreters service (English to Spanish and viceversa) wil be ofered during all oral presentations.

  • REVIEW of the ATLANTIC STATES MARINE FISHERIES COMMISSION's INTERSTATE FISHERY MANAGEMENT PLAN for SPINY DOGFISH (Squalus Acanthias)
    REVIEW OF THE ATLANTIC STATES MARINE FISHERIES COMMISSION'S INTERSTATE FISHERY MANAGEMENT PLAN FOR SPINY DOGFISH (Squalus acanthias) May 2004 – April 2005 FISHING YEAR Board Approved: February 2006 Prepared by the Spiny Dogfish Plan Review Team: Ruth Christiansen, ASMFC, Chair I. Status of the Fishery Management Plan Date of FMP Approval: November 2002 Date of Addendum I Approval: November 2005 Management Unit: Entire coastwide distribution of the resource from the estuaries eastward to the inshore boundary of the EEZ States With Declared Interest: Maine - Florida Active Boards/Committees: Spiny Dogfish and Coastal Shark Management Board, Advisory Panel, Technical Committee, Stock Assessment Subcommittee, and Plan Review Team In April 1998, the National Marine Fisheries Service (NMFS) declared spiny dogfish overfished. The Mid-Atlantic and New England Fishery Management Councils jointly manage the federal spiny dogfish fishery. NMFS partially approved the federal FMP in September 1999, but implementation did not begin until the May 2000, the start of the 2000-2001 fishing year. The federal FMP uses a target fishing mortality to specify a coastwide commercial quota and splits this quota into two seasonal periods (Period 1: May 1 to October 31 and Period 2: November 1 to April 30). The seasonal periods also have separate possession limits that are specified on an annual basis. In August 2000, ASMFC took emergency action to close state waters to the commercial harvest, landing, and possession of spiny dogfish when federal waters closed because the quota was fully harvested. With the emergency action in place, the Commission had time to develop an interstate FMP, which prevented the undermining of the federal FMP and prevented further overharvest of the coastwide spiny dogfish population.

  • Acipenser Brevirostrum
    AR-405 BIOLOGICAL ASSESSMENT OF SHORTNOSE STURGEON Acipenser brevirostrum Prepared by the Shortnose Sturgeon Status Review Team for the National Marine Fisheries Service National Oceanic and Atmospheric Administration November 1, 2010 Acknowledgements i The biological review of shortnose sturgeon was conducted by a team of scientists from state and Federal natural resource agencies that manage and conduct research on shortnose sturgeon along their range of the United States east coast. This review was dependent on the expertise of this status review team and from information obtained from scientific literature and data provided by various other state and Federal agencies and individuals. In addition to the biologists who contributed to this report (noted below), the Shortnose Stugeon Status Review Team would like to acknowledge the contributions of Mary Colligan, Julie Crocker, Michael Dadswell, Kim Damon-Randall, Michael Erwin, Amanda Frick, Jeff Guyon, Robert Hoffman, Kristen Koyama, Christine Lipsky, Sarah Laporte, Sean McDermott, Steve Mierzykowski, Wesley Patrick, Pat Scida, Tim Sheehan, and Mary Tshikaya. The Status Review Team would also like to thank the peer reviewers, Dr. Mark Bain, Dr. Matthew Litvak, Dr. David Secor, and Dr. John Waldman for their helpful comments and suggestions. Finally, the SRT is indebted to Jessica Pruden who greatly assisted the team in finding the energy to finalize the review – her continued support and encouragement was invaluable. Due to some of the similarities between shortnose and Atlantic sturgeon life history strategies, this document includes text that was taken directly from the 2007 Atlantic Sturgeon Status Review Report (ASSRT 2007), with consent from the authors, to expedite the writing process.

  • The Use of Marine Reserves for Inshore Fisheries
    Managing fisheries without restricting catch or effort : the use of marine reserves for inshore fisheries Daniel S. Holland11[a]1 Department of Environmental & Resource Economics University of Rhode Island Abstract Although widely accepted, management systems that directly restrict catch or effort are neither efficient nor desirable for many fisheries, and have failed to conserve fishery stocks in many cases. Fisheries scientists have suggested that closing part of the fishery with marine reserves may sustain or increase harvest. These marine reserves act as natural hatcheries and nurseries in which reproduction and growth are not impeded, and supplement the surrounding fishery. Empirical studies of marine reserves have focused on the conservation benefits only inside the reserves. I develop a dynamic model and numerical simulation of a fishery for which a marine reserve is introduced. Net present value of fish harvests are maximized as a function of reserve size with total effort assumed constant. Unlike previous models, the time path of harvests and fish stocks prior to reaching a new steady-state is determined. This is important because the full impact of the reserve may not be realized for several years. The model suggests that reserves may increase the net present value of the fishery when total effort is high and can not be regulated directly. Higher discount rates reduce the optimal size of reserves. Introduction Conventional methods of regulating commercial fisheries including licenses, catch quotas, taxes on catch or effort, gear restrictions and closed seasons restrict catch by limiting either the quantity or efficiency of fishing effort, or by putting direct limits on total catch (Cunningham 1983).

  • Columbia Basin White Sturgeon Planning Framework
    Review Draft Review Draft Columbia Basin White Sturgeon Planning Framework Prepared for The Northwest Power & Conservation Council February 2013 Review Draft PREFACE This document was prepared at the direction of the Northwest Power and Conservation Council to address comments by the Independent Scientific Review Panel (ISRP) in their 2010 review of Bonneville Power Administration research, monitoring, and evaluation projects regarding sturgeon in the lower Columbia River. The ISRP provided a favorable review of specific sturgeon projects but noted that an effective basin-wide management plan for white sturgeon is lacking and is the most important need for planning future research and restoration. The Council recommended that a comprehensive sturgeon management plan be developed through a collaborative effort involving currently funded projects. Hatchery planning projects by the Columbia River Inter-Tribal Fish Commission (2007-155-00) and the Yakama Nation (2008-455-00) were specifically tasked with leading or assisting with the comprehensive management plan. The lower Columbia sturgeon monitoring and mitigation project (1986-050-00) sponsored by the Oregon and Washington Departments of Fish and Wildlife and the Inter-Tribal Fish Commission also agreed to collaborate on this effort and work with the Council on the plan. The Council directed that scope of the planning area include from the mouth of the Columbia upstream to Priest Rapids on the mainstem and up to Lower Granite Dam on the Snake River. The plan was also to include summary information for sturgeon areas above Priest Rapids and Lower Granite. A planning group was convened of representatives of the designated projects. Development also involved collaboration with representatives of other agencies and tribes involved in related sturgeon projects throughout the region.

  • On the Economics of Harvesting Age-​Structured Fish Populations
    On the economics of harvesting age-structured fish populations* Olli Tahvonen∗∗ Fishery and Environmental Management Group, FEM University of Helsinki, Department of Biological and Environmental Sciences November 2007 Abstract A generic discrete time age-structured population model is integrated with fishery economics to derive analytical results for maximizing present value re- turns net of effort cost. The simplest case is obtained by assuming two age classes. Given knife-edge selectivity and no harvesting cost, the optimal steady state is a unique (local) saddle point. When fishing gear is nonselective, optimal harvesting may converge toward a stationary cycle that represents pulse fish- ing. Optimal steady states differ from those obtained by the aggregate biomass models. This implies that optimal extinction results depend on age structured information. Given a low rate of interest and knife-edge selectivity, the optimal harvesting is shown to converge toward a unique (local) saddle point indepen- dently of the number of age classes. Keywords: Fishery economics, optimal harvesting, age-structured popula- tions This paper has been presented in International Workshop on Structured Models∗ in Population and Economics Dynamics, Vienna November, 2007. Permanent address: Finnish Forest Research Institute, Unioninkatu 40 A, 00170∗∗ Helsinki, Finland. E-mail: olli.tahvonen@metla.fi 1 1 Introduction Optimal harvesting of biologically renewable populations (such as fish and trees) is among the classical problems of resource economics. One line of research that dates back to Baranov (1918) aims to utilize information on the population age-structure in searching desirable levels of harvesting effort, or as is possible in some cases, the age class to which the harvesting activity should be targeted.

KEY WORDS: benthic invertebrates, density dependence, limitation, population dynamics, reef fishes, regulation, settlement ABSTRACT The majority of marine populations are demographically open; their replenish- ment is largely or exclusively dependent on a supply of juveniles from the plank- ton. In spite of much recent research, no consensus has yet been reached regarding the importance of recruitment relative to other demographic processes in deter- mining local population densities. We argue 1. that demographic theory suggests that, except under restrictive and unlikely conditions, recruitment must influence local population density to some extent. Therefore, 2. the question as to whether the size of a particular population is limited by recruitment is misguided. Finally, 3. the effect of recruitment on population size can be difficult to detect but is nonetheless real. A major weakness of most existing studies is a lack of attention by University of North Carolina - Wilmington on 08/03/09. For personal use only. to the survival of recruits over appropriate scales of time and space. Acknowl- Annu.

  • Eulachon (Thaleichthys Pacificus) Marine Ecology: Applying Ocean Ecosystem Indicators from Salmon to Develop a Multi-Year Model of Freshwater Abundance
    Eulachon (Thaleichthys pacificus) marine ecology: applying ocean ecosystem indicators from salmon to develop a multi-year model of freshwater abundance Sarah A. Montgomery A thesis submitted in partial fulfillment of the requirements for the degree of Master of Marine Affairs University of Washington 2020 Committee: Cleo Woelfle-Erskine Robert Anderson Program Authorized to Offer Degree: Marine and Environmental Affairs © Copyright 2020 Sarah A. Montgomery Abstract Eulachon (Thaleichthys pacificus) marine ecology: applying ocean ecosystem indicators from salmon to develop a multi-year model of freshwater abundance Sarah A. Montgomery Chair of the Supervisory Committee: Dr. Cleo Woelfle-Erskine School of Marine and Environmental Affairs Complex ecological processes determine whether and how fish species survive in the ocean. For some fishes such as Pacific salmon (Oncorhynchus spp.), these processes are thoroughly studied and modeled. For eulachon (Thaleichthys pacificus), however, these processes are more mysterious despite their trophic link to salmon and similar anadromous life history. The ocean ecology of eulachon was identified by the National Oceanic and Atmospheric Administration (NOAA) as a key knowledge gap and research priority for eulachon, which were listed under the Endangered Species Act as a threatened species in 2010 after suffering significant declines throughout the southern portion of their range. Eulachon are a culturally and historically important species for Native nations, as well as a critical component of freshwater, estuarine, and marine food webs. So, a decline in their abundance has motivated researchers to better understand what drives fluctuations in their populations, despite a lack of data in the marine environment. The marine ecology of eulachon may be relatively understudied, but data collected and compiled for salmon can partially fill this gap.
