“…In Comoro, our key participants were predominately young and literate (some with university education) with access to television and internet, which they drew on and referenced in our discussions. While our study took a broad, exploratory, inclusive approach, factors such as age, experience and background have been shown in previous studies to have important implications for investigations into local knowledge and fisher knowledge (Johannes et al, 2000;Berkström et al, 2019).…”

“…Such knowledge is increasingly recognized as part of the 'best available information' for scientists and fisheries managers (Stephenson et al, 2016), and can be the only source of information on the diverse fisheries resources of many tropical developing countries. A growing body of literature has investigated fishers' local knowledge of fishes' habitat preferences, spawning behavior, migrations and habitat connectivity, abundance trends over time and other topics, and sought to combine local knowledge with western scientific knowledge (Johannes, 1978;Ruddle and Hickey, 2008;Lavides et al, 2010;Silvano and Begossi, 2012;Berkström et al, 2019).…”

Tropical sardines (Family Clupeidae) are an important component of many marine fisheries in the Indo-West Pacific region. In Timor-Leste, a small, less-developed country within this region, ‘sardiña’ are some of the more commonly caught and consumed fish. Yet there is little published information from Timor-Leste about the species composition of these fisheries, nor their biology or ecology. We document the knowledge of Timorese fishers on nine locally distinguished sardine types that contribute to fisheries, and relate these to at least nine species: four species of ‘Flat-bodied Sardinellas’ (Sardinella subg. Clupeonia spp.), one species of ‘Round-bodied Sardinella’ (Sardinella subg. Sardinella lemuru), two species of ‘Tropical Pilchards’ (Amblygaster spp.) and a ‘Tropical Herring’ species (Herklotsichthys quadrimaculatus), all from the Clupeidae family; and one Dussumieria species from the Dussumieriidae family. We record variations in local sardine names across the country and document aspects of fishers’ knowledge relevant to understanding and managing the fisheries, including local sardine species’ seasonality, habitat, movements, interannual variation, as well as post-harvest characteristics in relation to perishability. In general, local names relate more closely with groups of species than individual species, although some names also distinguish fish size within species-groups. The local knowledge identified in this study has immediate application to inform fisheries monitoring and management, and to identify areas for future research. Notably, Timorese fishers recognize and make use of the strong association between some sardine species-groups and seasonally turbid river plumes. While further research is required to understand the underlying mechanisms of this association, this emphasizes the need to consider coastal fisheries and fisher livelihood impacts when assessing any plans or proposals that may alter river flow or water quality. Fishers also recognize migratory behavior of some sardine species, in particular the Flat bodied Sardinellas (S. gibbosa and others) along the north-west coast of Timor-Leste and across the border into Indonesian West Timor. Such insights complicate and need to be accounted for in initiatives for co-management or community-based management of Timor-Leste’s coastal waters and their fisheries.

“…Knowledge network strength is also an essential feature of complex SES, considering that the ability of social actors to use and spread information is key in structuring an equitable social structure to support participatory deliberative processes [15], promoting a qualitatively critical basis for management initiatives [16,17]. Collaborative networks are potential multipliers of information relevant to decisionmaking by social groups [13,18], including those related to artisanal shing [19,20]. Speci cally, multiplication potential can be in uenced by attributes such as the amount of interactions and the degree of cohesion of the network [21], the position of individuals in the network [22], and the presence of central informants [23,24] and subgroups in a community [25].…”

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.

“…Other locations' lack of records may be a more accurate representation of a gap in academic knowledge. Africa's west and eastern coasts are known to be understudied ecosystems, and so the missing research here is likely not just untranslated (Berkström et al, 2019). As in other ecological inquiries, the expansion of Local Ecological Knowledge into the study of gelatinous zooplankton should be considered, as fishermen and coastal communities often have a deep knowledge of organisms and their associations (Berkström et al, 2019).…”

As in other ecological inquiries, the expansion of Local Ecological Knowledge into the study of gelatinous zooplankton should be considered, as fishermen and coastal communities often have a deep knowledge of organisms and their associations (Berkström et al, 2019). Fishermen are often well acquainted with specific gelatinous zooplankton species and know their harms, and may have knowledge of symbionts living upon or within them (Al-Rubiay et al, 2009).…”
