Management, Governance, Scientific and Socio-economic Attributes Driving Successes or Failures in Meeting Fishery Objectives

Fisheries vary along a wide range of attributes, which may influence the extent to which numerous fishery objectives are met. Some attributes may enable some objectives to be met while others may impose barriers. The variability in attribute profiles between fisheries makes it challenging to identify strong influences of specific attributes and achieve success across multiple objectives. In this session, we bring together different approaches used to evaluate the potential influence of broad fishery attributes on meeting fishery objectives and strengthening fisheries management. To achieve this, we invite presentations that address fishery objectives, expert survey or data synthesis studies across multiple fisheries, decision-support tools that may help to identify promising actions to take, and seafood certification and ratings systems that specify criteria related to both fishery attributes and specific objectives. Presenters will each place their findings within the session’s aims of better understanding linkages between fishery attributes and objectives.

Management of Recreational Fisheries Accounting for Social Benefits, Economic Value, and Biological Sustainability

Recreational fisheries can represent a significant source of fishing mortality, have impact on ecosystems, and interact with commercial fisheries and other users of the marine environment. However, the evidence needed to manage these fisheries is often limited and difficult to collect. This theme session is an opportunity to share experiences and critically examine approaches developed across the globe. Participants will verify the role of recreational fisheries, identify how to incorporate recreational fisheries survey data into assessment to improve scientific advice, discuss effective engagement and co-management approaches, and explore different models for management of recreational fisheries considering biological, economic, and social goals.

Making a Case for Ending Bottom Trawling

Bottom trawling is a very common and highly destructive type of fishing gear, imposing significant ecological, social and economic costs. Decisions on trawl fisheries management pose notable policy challenges. During this symposium, we report on our biological, socio-economic and policy research into bottom trawling. We present an analysis of the bias in trawl studies by spaces and species. Our biological studies probe (i) how many fish species are caught and (ii) how trawling affects threatened species. Our socio-economic studies investigate (iii) what brings people into bottom trawling, why they stay, and what makes them leave and (iv) probes the costs and benefits to different actors in bottom trawl fisheries and associated industries. Our management and policy studies examine (v) what happens in areas where bottom trawling is excluded and (vi) how bottom trawling undermines global agreements.  We invite colleagues to consider how our research influences the agenda for bottom trawling.

Looking to the Past to Anticipate the Future of Freshwater Fishes in a Changing World

Global environmental changes such as habitat loss, pollution, climate change and invasive species are eroding the biogeography of fishes across marine, transitional, and fresh waters, with important consequences for the stability of aquatic ecosystems and provisioning of ecosystem services. In this special session we aim to look back at the past and evaluate current and future risks to fish diversity at the species, community, and ecosystem level. We will particularly focus on novel approaches to document, predict and mediate biodiversity changes and build a sustainable future for aquatic ecosystems. We expect contributions on topics including (but not limited to) population genomics to detect evolutionary impacts, compilation of historical information to track biodiversity changes across centuries, time series analysis using data generated by citizen science groups or national monitoring networks to unveil the response mechanisms to past and current pressures, and predictive modelling aiming to guide conservation decision-making.

Leveraging Fishery-dependent Data in Stock Assessments and Fisheries Management: Working at the Interface of Observer and Electronic Monitoring Data

Fishery-dependent data is used to inform fisheries managers and stock assessments across the globe; however, the types of data collected and the structure of monitoring programs is diverse and best practices for incorporating these data into stock assessments is a topic of broad interest and discussion. In particular, the expansion of electronic monitoring (EM) creates challenges for incorporating data from both observer and EM data streams in stock assessments. This session will focus on optimizing the incorporation of EM data with observer data in stock assessments. Through a mix of formal research presentations, breakout groups, and expert panel discussions, this session will explore how to effectively integrate multiple data types into stock assessment processes and other analyses to support management.

Learning from Each Other to Build Effective Networks for Innovative and Effective Governance to Sustain Iconic Diadromous Fishes

The complex life history strategies of diadromous fishes, using both ocean and freshwater habitats and often crossing political borders makes them particularly vulnerable to anthropogenic activities. The development of successful governance models acceptable to all stakeholders poses a challenge but it remains a priority for sustaining these often-iconic species. This session will present a range of examples of existing multi-user collaborations in the assessment and management of diadromous species from around the world. This would be the starting point for a post-session review describing and discussing the species- or situation-specific challenges and commonalities of multilateral collaborations for diadromous species. Thus the session will leverage the collective knowledge to identify, plan, and initiate select case studies to establish knowledge exchange frameworks to support multilateral collaboration and the conservation of diadromous species.

Innovations in On-Demand Fishing

This full-day session will focus on the latest advancements, obstacles, and problem-solving pertaining to on-demand fishing. On-demand, or “ropeless,” systems eliminate static rope in the water column compared to fishing with traditional pot/trap gear designs. In traditional methods, gear is tied to a rope that is attached to a buoy at the surface of the water. The main characteristic of on-demand gear is that it doesn’t need this tether between gear and buoy. The presentations in this session will give attendees relevant background information about on-demand technologies, its purpose, as well as implementation and testing-related challenges. Through additional formal presentations, the session will also provide an overview of specific global case studies of on-demand fishing. After the presentations, there will be roundtable conversations where attendees and presenters may explore the innovations of on-demand fishing and what is necessary to increase success in the future.

Indigenous Stories and Relationships with Fish, Water, and Energy

Indigenous peoples have lived with and developed relationships with other species/beings (e.g. water, fishes) for thousands of years. During this time, lessons were learned, stories were told, songs were sung, norms developed that shaped how these indigenous people used, respected, and cared for these other beings. Many of the ways in which indigenous people learned about their environments remain important today and help to guide relationships. We encourage presentations that speak to the relationship indigenous people have developed with species/beings especially as to how these relationships affect water and foods. We also encourage topics that explore how indigenous knowledge can be incorporated into relationship/management plans to build social-ecological resilience and adaptation to a changing environment.  Presentation length can be from 5-20 minutes in length.

Indigenous People and Local Community-led Fisheries Management

This session elevates the contribution of Indigenous people and local communities (IPLCs) in global fisheries as users, managers and leaders in defining and driving conservation and sustainable fisheries management.

Indigenous people and local communities comprise most fishers globally by numbers, often participating in mixed activities for nutrition and livelihood. In doing so, they also act as resource managers and stewards through formal and informal rules. Integrating the vision and existing governance of these fishery actors, through community-based and co-management approaches, is challenging yet necessary.

A global range of presentations are invited to highlight the diverse roles and contributions of IPLCs in fisheries and explore pathways increasing their critical contribution to fish conservation and fisheries management.

Incorporation of Ecosystem Information into Fisheries Management Decisions

Failure to translate ecosystem science into management action can result when information is not conveyed to the appropriate management body or because of the nature of the information or the quality of the communication. We welcome contributions on products and processes that have been used to improve the conveyance of ecosystem information into the fisheries management process, especially those that have been used to inform tactical fisheries management decisions. We encourage studies that propose and/or compare products, processes, timing, visualization, and targeted audiences, as part of the management cycle. The end goal is to identify decision points, tools, and types of information that maximize uptake into fisheries management decisions and to identify the scales and contexts in which the various approaches work best. The formal presentations will be followed by a roundtable discussion among fisheries managers and policymakers to discuss the possibilities and challenges of applying the work presented.
