Generating fishery monitoring and data analysis for clams and tripe

The collection of fisheries data is one of the commitments acquired when there is a right of access to the resource, as well as when working under a sustainable fisheries scheme. In order to demonstrate that the fishery is developing its activities under this scheme, data and information are obtained by implementing a fishery monitoring system.

The clam and tripe fishery had been characterized by a sustainable fishery, however, there was no data systematically captured to document the activities carried out in the long term. To address this need, COBI and community partners jointly implemented a fishery monitoring program. With the fishermen and fisherwomen, a logbook was designed with data such as date, time, boat, diver, target species, fishing site, number of organisms, size of organisms collected, income and expenditure. All the members of the cooperatives and fishing technicians were trained to fill out the fishing logs and one person per fishing cooperative was responsible for recording the data.

  1. Adapt, with the fishing communities, the design of fishery monitoring based on community and fishery conditions, e.g., agree with fishermen whether it will be conducted on board the vessel or on land.
  2. Train fishermen and fisherwomen in data collection for logbooks, including clam and callus lengths, as well as database management.
  1. Coordination with fishermen and fisherwomen for the design and implementation of fishery monitoring is essential for the information recorded to be effective and for them to be related to the logbook format.
  2. It is recommended to include the authorities in the design of fishery monitoring, since this information is required as part of the duties derived from the permits or concessions; it is also very valuable to know the state of the fisheries.
  3. It is important that fishermen and fisherwomen know the results generated with the analysis of the data recorded in the fishing logs. This reinforces the importance of generating information.
Designing and implementing harvesting strategies for clams and calluses

A harvest strategy is a set of formally or traditionally agreed tools used to ensure good resource utilization. In clam and tripe fisheries, harvest strategies are defined based on the best available information. However, sometimes the strategies and rules are not applicable with the same recipe throughout the country due to variations in the biological, environmental and social conditions of each region. This lack of information at the local level poses a challenge to define strategies according to the local characteristics of the fishery and to evaluate its performance. To address this need, we have worked together with all the stakeholders involved (fishing communities, government, academia and civil society organizations), generating information through fishing logs to ensure that fishing is carried out in accordance with the strategies implemented. By incorporating the knowledge of the communities to the information recorded, it is possible to generate new participatory strategies, better adapted to local conditions.

  1. Combine scientific and traditional knowledge as a baseline for designing sustainable harvesting strategies.
  2. Socialize the strategies agreed upon by the government sector with clam and tripe fishermen and fisherwomen.
  3. It is important that, once fishermen and fisherwomen are aware of the harvesting strategies, they adopt and respect them.
  1. The use of logbooks promotes better management of the resource and contributes to the sustainability of the fishery. Logbooks should document biological, ecological and fisheries information on the species caught.
  2. The effective participation of fishing communities in generating useful information for management allows for a more robust analysis of fisheries, particularly important in fisheries with little data, as well as maximizing fishery utilization.
  3. The results obtained from harvesting strategies should be documented, with the intention of being able to analyze their effectiveness over time, making adjustments and allowing them to be scalable. This evidence helps to publicly demonstrate the commitments made towards fisheries sustainability.
Integrated management zones: a tool for restoring clam and tripe fisheries

Integrated management zones (IMZ) are an innovative approach for the management and recovery of bivalves, applied in the clam and callus fisheries in Mexico. To implement this tool, the following was done: 1) the work area was defined and delimited; 2) areas with suitable characteristics for bivalve culture were identified with the communities; 3) biological (measurements and weight of the organisms) and ecological (abundance, diversity, richness and distribution of the species) information was generated for the proposed area, and it was submitted to a vote among the users for its establishment as IMZ; and, 5) systematic monitoring was implemented to identify long-term changes.

This story began with a cooperative that wanted to recover the populations of callo de hacha. It was later replicated by a cooperative of young commercial divers and later by a group of women who consolidated as a cooperative to recover the estuarine clam population. The results have been positive; e.g., the population of callo went from 0 to 13,000 individuals in five years in an area of 25 hectares, collecting seeds from the natural environment.

  1. The adaptive capacity of the communities to transition from artisanal fishing to an artisanal aquaculture and mariculture scheme.
  2. Technical and financial support from the government sector, academia and civil society organizations.
  3. Integrate traditional, technical and biological knowledge about the target species when designing the IMZ.
  4. Present progress and results periodically to the government sector, to promote institutional interest in supporting these innovative work schemes.
  1. The communities' capacities were strengthened in clam and callus biology, aquaculture and mariculture theory and practice (stages of cultivation), and monitoring.
  2. Collaboration with the government sector and academic experts in cultivation is of utmost importance for the implementation of this activity and the collection of larvae for fattening.
  3. The recovery of a clam and callus bank for use can take three to five years, depending on the species, which can discourage producers. It is important to have this information beforehand, so as not to generate false expectations of immediate recovery.
  4. The integrated management of resources with exclusive access rights promotes the empowerment and co-responsibility of fishermen and fisherwomen.
  5. The successful management of a callos IMZ led to the replication of the tool by a women's cooperative, which developed a similar project for the recovery of estuarine clams.
Sustainable conservation and management approaches for large sites

The nature of Herculaneum’s burial 2000 years ago meant that open-air excavation in the early 20th c. revealed an extraordinary level of preservation of the Roman town but had to be accompanied by the stabilization of these multistorey ruins, and the reinstatement of roads and drainage systems. The site today requires conservation of the archaeological fabric but also of these aging restoration interventions, and at an urban scale.

However, efforts at Herculaneum in the late 20th c. approached the site as a series of individual elements. This was partly due to limited access to interdisciplinary expertise and steady funding sources – sporadic capital funding for one-off localised projects predominated.

With the turn of the millennium, a new approach was taken that mapped conservation issues and interdependencies between them across the entire site, and acted on them. Initial efforts focused on resolving situations in areas at risk of collapse or with vulnerable decorative features. Over time the focus shifted to long-term strategies for reducing the causes of decay and developing site-wide maintenance cycles sustainable by the public authority alone so that the site would not revert back. With these now entirely sustained by the public partner the overarching objective has been achieved.

Developments in Italian legal frameworks in 2004 allowed the private partner to contract conservation works directly and ‘donate’ concrete results, instead of financial support only. This allowed the partnership to constitute genuine operational enhancement of the existing management system.

Further legal reforms for cultural heritage in the period 2014-2016 then enhanced the public partners’ flexibility and responsiveness to the site’s needs.

  • Interdisciplinary analysis and decision-making for large heritage sites can be enhanced through the use of user-led data management tools. Integrating interdisciplinary IT tools in conservation planning, implementation and monitoring was crucial to greater effectiveness in the use of limited resources; human, financial and intellectual.
  • The long timeframes available for the partnership and the year-round presence of an interdisciplinary team allowed the development of a comprehensive and nuanced understanding of the site’s needs, and extensive testing of long-term strategies to address them, before handing over maintenance regimes to the public heritage authority.
  • Extensive and problematic 20th c. restoration interventions are a challenge faced by a lot of built heritage where more knowledge sharing is desirable.
  • The Covid-19 pandemic has exposed the financial vulnerability of the institutional model in the absence of ticketing income and uncertainties regarding the capacity of the public partner to sustain the improvements to site conservation and maintenance in the long term.
Stewardship Planning Process

A Local Stewardship Council (LSC) is the main representative of a World Surfing Reserve and is in charge of implementing the Local Stewardship Plan. The LSC works together with Save The Waves Coalition to Protect, Steward, and Defend their surf ecosystem.

 

LSC members work on the ground and with the local community to carry out activities that result in the long-term conservation of the reserve as well as celebrate and honor the tradition of surfing and ocean recreation.  The Stewardship Planning Process brings together the LSC and important community members to map out the the critical threats to the region and come up with long term goals and objectives for permanent protection.  

 

The Stewardship Planning Process generally follows the outline in "Measures of Success" that includes building a Conceptual Model, developing a management plan that identifies goals, objectives, actions and timelines based on the threats to address.

Enabling Factors include:

 

  • A well developed Local Stewardship Council
  • Support from the local government or municipality
  • Maps of the region and coastline
  • A well developed inventory of threats to the environment
  • A comfortable physical meeting space

Our lessons learned from this project include:

 

  • Relationship building between the stakeholders is key
Surfonomics

“Surfonomics” aims to document surfing’s economic contributions to local and regional economies. Through Surfonomics research, we determine the economic value of a wave and surfing to local communities to help decision makers make better choices to protect their coastal resources and waves.

 

Using a beach survey of surfers in San Miguel, Ensenada, we were able to quantify that an average tourist spends approximately $111 US dollars a day. As the average surfer spends 10 days per year in the area, it is calculated that a visiting surfer spends $1,151 US dollars a year in Ensenada. 

 

These figures show that surfing helps drive the local economy of Ensenada and that decision-makers must take into account the importance of the surf zone in terms of coastal management.

  • Volunteers to carry out the survey instrument
  • Partnerships with academic institutions 
  • A broad coalition of stakeholders is needed to carry out a rigorous academic study like Surfonomics. Relationships and trust must be built with local hotels and rental agencies, business owners, tourism agencies, surf shops and businesses, and most importantly, the surf community itself.  All of these stakeholders must share information and participate in the study in order to get an accurate picture of the economy of surf tourism in a given area.

Key lessons include:

 

  • Understanding the economic contribution of surfing is key to getting stakeholders to agree on conservation initiatives.
  • Running a surfonomics study can help practitioners understand the attitudes and perspectives of visitors to the area.
  • Surfers spend a significant amount of time and money traveling and bring big economic contributions to local communities.
Advanced technologies enhance surveillance

Investment in a radar tracking system for broader monitoring of the area. The radar tracking system is real-time monitoring speed, and directional heading of the boat in the marine protected area's vicinity. The radar information can infer the type of activity of the boat is likely to be engaged in the sea. For example, a fish trawler boat that is trawling tends to move at a slower speed of 7-10 kph than a passing trawler that usually travels at a speed of 16 – 20 kph. Furthermore, five blast detectors were installed to monitor and analyse blast fishing activities within SIMCA. The blast detector's information enables the Reef Guardian enforcement team to do strategic sea patrol to increase enforcement presence in the hot spot where illegal fish bombing often occurred.

  • Investment from a partner organization (Conservation International Philippine) on a radar tracking system in 2009.
  • Joint partnership with Reef Defender from Hong Kong since 2014 in the mission to reduce fish bombing in the region.
  • Information from the radar reduces operational cost (boat fuel) where the team show enforcement presence on the hot spot areas, instead of patrolling the entire marine protected area.  
  • Radar information is best for night enforcement activities. The information giving a higher chance to intercept illegal fishing activities on the spot which lead to higher success on detection and detention rates.
Generating fishery monitoring and information analysis for fish

One of the most immediate challenges facing fish fisheries on their path to fishery sustainability is the implementation of fishery monitoring. This gathers all the information needed to understand how the fishery functions, including its economic and ecological components, allowing better management decisions to be made. To achieve this in the fish fishery, fishermen and fisherwomen were trained on the importance of monitoring their fisheries and how to carry it out. Together with the fishing communities, the government sector, academia and civil society organizations, a fishing logbook format was designed and approved by the government.

Subsequently, the logbooks were implemented in four fishing communities, adapting the process according to local needs. 2021 marked four years since the communities began monitoring their fisheries (specifically for different species of fish), which has allowed them to make inferences on the behavior of the fishery, plan their activities, monitor their income, etc.

  1. Design the logbook with all the actors involved in the fishery (fishermen, government sector, academia, market and civil society organizations).
  2. Place a section in the logbook to record lengths and weights of fish caught.
  3. Ensure that fishermen have the necessary equipment to carry out fishery monitoring.
  4. Train fishermen on how to take parameters (e.g. fish lengths) for biological and fishery monitoring.
  1. It is important to define how the fishers will be recording the logbooks. The process should be adapted to local conditions (the fishery, the internal organization of the cooperative and community), and maintain a standardized data collection methodology. It is possible for each person to do his or her logbook when returning from fishing or for only one person to be in charge (e.g. in the product reception area).
  2. Due to bycatch of certain species, it is important that fishermen and fisherwomen are trained to take photographs and to identify morphological characteristics and coloration patterns of bycatch species in order to identify them.
  3. The results of the analysis of the logbook information have been used to define management strategies, such as increasing the mesh size of the traps used or modifying the number of hooks to avoid catching smaller organisms.
Co-investment for sustainable fisheries

To achieve success in the sustainability of fishery resources, there must be active participation of diverse stakeholders (fishing communities, government sector, academia, civil society organizations and the market). In 2018, COBI began monitoring the costs (economic and in-kind) associated with the implementation and development of fishery improvement projects. From this exercise, it was documented that generally at the beginning of the projects, philanthropy makes the largest economic investment through CSOs, while fishing communities make it in-kind (e.g. making their boats available for activities), and other actors also participate (e.g. government bodies or academia). The objective of community co-investment is to ensure that, over time, the fishing communities become organized and committed to continue paying the costs associated with this type of project, and to achieve greater financial autonomy. COBI and the fishing communities jointly developed a written strategy with a five-year term, in which the communities commit to maintain a gradual percentage of economic contributions to achieve co-responsibility and manage the project on their own.

1. Stakeholders are aware of the project's costs and have a gradual financial strategy for co-investment.

2. Stakeholders have transparent and accountable processes in place to build trust, and thus sustain fishery improvement projects in the long term.

  1. Mapping the stakeholders in the co-management of the fishery from the beginning. This makes it possible to make visible all those who can/should participate in the financial contributions of improvement practices and project monitoring.
  2. Integrating and training all actors involved in the value chain on the importance and benefits of being co-investors in fishery improvements.
  3. Consider financial and in-kind contributions (e.g. human capital, time invested, data/information generation, infrastructure-meeting space). This allows valuing, recognizing, and making visible the contributions and commitment to sustainable fisheries from each sector.
  4. Achieving co-investment is not a simple process, as it involves financial issues. For this reason, it is necessary to train participants and make them recognize its importance.
Visioning for the future of the Denali region

The purpose of visioning for the future of the Denali region is to evaluate stakeholder preferences and trade-offs they are willing to make when thinking about the future of the region. Identifying distinct visions for the future is important in places like Interior Alaska where impacts from climate change are magnified and anticipated to rapidly transform the social-ecological landscape. This information can inform decision-makers about priorities for the future across a gamut of stakeholders and serve as a foundation for participatory planning. This study evaluated visions as part of a mixed mode household survey administered to residents across the Denali region.

 

To identify preferences and trade-offs for future conditions, a discrete choice experiment that evaluated the strengths of preferences and trade-offs for future conditions of the Denali region was included. Survey data were used to understand preferences for attributes including wildlife populations, off-season tourism, and fire management, as well as the cost of maintaining current conditions of these attributes. Results showed that all of these factors influenced preferences for the future, and that the range of environmental attitudes held by stakeholder groups accounted for variation in the strength of preferences reported by survey respondents.

Previous work that qualitatively evaluated residents’ perceptions of landscape change and knowledge were instrumental in the success of this building block. In particular, an in-depth understanding of relevant landscape features was built prior to developing the parameters in our discrete choice experiment. The collection of pilot testing data was also important to refine the language used in our survey and range of changes that were considered realistic future conditions in the region. 

Evaluating residents’ preferences for future landscape conditions and trade-offs they are willing to make when thinking about the future yielded important insights about residents’ priorities. This is crucial information for decision-makers to more effectively meet the needs of their constituencies. The development of this building block also taught lessons about the value of creative, mixed-mode strategies for data collection that would increase the likelihood of diverse perspectives being reflected in the final sample. Overall, working with local stakeholders to understand visions for the future was useful for generating empirical evidence that showed the relative importance of features that describe the Denali landscape. Results are also useful for anticipating resident support or resistance to changes in visions for the future in ways that can help decision-makers understand distinct stakeholders' viewpoints.
