We analyzed fishermen's local ecological knowledge (LEK) about the feeding habits, trophic interactions, habitats, fishing grounds, migration, and reproduction of nine coastal fishes in Búzios Island, southeastern Brazilian coast. We interviewed 39 fishermen using standardized questionnaires. Fishermen's LEK on habitat use and trophic interactions for the studied fishes agreed with the scientific literature, allowing the organization of reef and pelagic food webs. The interviewed fishermen mentioned that submerged rock formations would be important habitats for some large commercial fishes, such as Seriola spp., Caranx latus and Epinephelus marginatus. In some instances there was no scientific data to be compared with fishermen's LEK, and thus this kind of knowledge would be the only available source of information, such as for reproduction and migration of most of the studied fishes. We suggest herein ways to apply fishermen's LEK to develop and improve fisheries management measures, such as zoning of marine space, marine protected areas, and closed fishing seasons. Fishermen's LEK may be an important and feasible support to fisheries management and co-management.

Abstract BackgroundLocal ecological knowledge (LEK) in fishing communities is generated through interactions between fishers and the exploited resources. It is transmitted through social networks, interdisciplinary structures that drives the dynamics of socio-ecological systems (SES). LEK variability is supposed to depend on the quality and quantity of ecological information flow among different stakeholders. To assess what is driving LEK themes, we hypothesized that the formation of LEK clusters among fishers is determined by network articulation, fisher experience and the commercial value of the exploited species. MethodsThe study area comprises three fishing communities in the Western South Atlantic, in the tropical coastal zone of Brazil where artisanal shrimp fisheries (on Penaeus schmitti, P. subtilis and Xiphopenaeus kroyeri) are a major activity. Data collection took place between March, April, and November 2019. To test our hypothesis, linear regression and bipartite network analyses were performed to visualize the interactions between fishermen groups and LEK themes. The connectivity, nesting, modularity, and centrality parameters in this social network were calculated to test the hypothesis. ResultsOur results indicate that experienced fishers enhance LEK in their networks on the themes of food, mortality, and growth. Furthermore, there are subgroups of fishers with dissimilar knowledge about the exploited shrimp species, one old on the fishery with wide knowledge, other less experienced, just knowing about reproduction and migration themes. ConclusionWe conclude that there is a spatial similarity in the connectivity of fisher’s LEK, mainly concerning the reproductive and migratory dynamics of the target species, but also differences permeated by fishers’ experience and local interests. Managers initiating co-management agreements using reproduction and migration referential variables as benchmarks will be more successful if they incorporate LEK into decision-making. Regional knowledge similarities favor the implementation of management policies at a regional scale potentially reducing conflicts within fishing communities and increasing resource use efficiency.

Abstract Indicators represent the link between objectives and action in management. The identification of ecosystem indicators must therefore be embedded in the decision-making process. Fisheries management can only be effective if the measures are considered legitimate by stakeholders. The choice of indicators to guide management should not be evaluated from a technical perspective alone, but also in relation to their effectiveness in communicating knowledge. More specifically, indicators should serve as a communication bridge between different knowledge discourses. Reference is often made to “local ecological knowledge” as a source that should be integrated in the process for management to be legitimate. However, while extensive studies have been made on local ecological knowledge per se, few have addressed the issue of its integration into co-management institutions with research-based knowledge. The challenge is consequently to identify indicators that have both research-based validity and reflect features that correspond to stakeholder knowledge, while relating to shared understandings of objectives and actions. This challenge is discussed from a developing-countries perspective. Problems and possible ways forward are illustrated on the basis of experiences from a range of case studies of knowledge discourses regarding living aquatic resources in southeast Asia and southern Africa. The studies have shown that the different knowledge discourses, and candidate indicators therein, relating to a specific ecosystem may be identified and characterized. Often, however, such indicators will have very little in common across knowledge discourses, and the differences cannot be overcome through a simple translation process. The perspectives of formal research-based knowledge and of fishers differ systemically, reflecting the different interests and scales of observation between the two parties. Also, fishers focus on a wider agenda than research alone, on allocation problems and conflicts among users. Allocation/access issues must therefore be addressed as an integral aspect of an ecosystem approach if management is to be effective.
