This research investigates local ecological knowledge of fishers in communities along a latitudinal gradient in the coast of the Santa Catarina State, regarding the life cycle of mullets Mugil liza (migration, feeding, and reproductive behavior). Our sampling encompassed eight Santa Catarina coastal cities (nine artisanal fishing sites) and engaged 45 key informants (28- 86 years of age) through semi-structured interviews from August/2011 to March/2012. This fish species feeds and grows in lagoon and estuarine systems, migrating to the sea for reproduction, and spawning. Fishers acknowledged the Patos Lagoon and the Plata River as the main source of mullet schools. Migration occurs from South to North and the routes vary according to climatic and oceanographic conditions (e.g., low temperatures, south winds, rainfall, currents, salinity). These conditions influence the abundance of mullets (and therefore fisheries success), their migration and stops in locations such as beaches, rocky shores, and islands. According to fishers, mullet spawning occurs throughout the coast of the Santa Catarina State and they feed in lagoons and riverine systems but also out at sea during migration. In conclusion, fishers possess a detailed knowledge about mullet life cycle and they identify intra and interannual variations in migration routes, a pattern that should be considered in managing the fishery.

Abstract Background The capture of ornamental fish is one of the main economic activities of riverine families in the Amazon. However, studies regarding the local ecological knowledge of workers in this activity are still incipient. In view of this, we have studied and explored the local ecological knowledge of artisanal fishers who specialize in the capture of fish for the aquarium trade in the middle part of the Negro River basin and investigated issues related to the ecological aspects of the fish species that are targeted by this trade in the region. Methods Therefore, we conducted semi-structured interviews and applied questionnaires to artisanal fishers of ornamental fish (N = 89), from the municipality of Barcelos, from January to April 2016. Results In total, 41 popular names were cited, which correspond to four ethnocategories and 10 families. The main species were Paracheirodon axelrodi (12.5%), Hemigrammus bleheri (8.3%), Ancistrus dolichopterus (6.4%), Symphysodon discus (5.3%), and Potamotrygon motoro (3.8%). According to the fishers, the species of fish known in the region as “piabas” have a preference for living in clusters (28.9%) and carry out migratory movements (26.1%). The diet of local fish species reported by fisheries is diverse, though mainly based on periphyton (42.2%), and the reproductive cycle directly influenced by the period of flooding of rivers in the region (37.6%) Conclusion Our study revealed that the fishers possess information on the ecological aspects of local ornamental fish species, many of which are consistent with scientific literature. The information presented may assist in the decision-making process for the management of local fishery resources and contribute to the resumption of growth and sustainability in the capture of ornamental fish.

Goliath Grouper

The goliath grouper Epinephelus itajara is a large sized (> 400 kg) and critically endangered marine fish, which is protected in many countries, including Brazil. Through the application of semi-structured interviews, we investigated the local ecological knowledge of seven fishermen specialist on catching E. itajara from the Babitonga bay, Santa Catarina, Brazil. Local long-line fisheries for E. itajara seemed to be a disappearing tradition in the studied site, with a detailed inherent local ecological knowledge system, which is also being lost. Our study also showed that fishermen engaged in recent fisheries, such as spear-fishing, can also possess a detailed local ecological knowledge system. Through the analysis of fishermen local ecological knowledge, several aspects of E. itajara life history were registered. This species is found in the inner and outer Babitonga bay, from saline waters to areas with a large input of freshwater, and inhabits submerged wooden substrates and artificial reefs such as shipwrecks, mooring pillars and cargo containers. It is known to spawn in December and subsequent summer months in the studied area. Spawning aggregations are usually seen in December (during full moon), being also eventually observed in January and February by our informants. While lobsters, spadefishes and octopuses seem to constitute the most important food items of inner bay E. itajara, outer bay individuals may feed on catfishes, crustaceans and other fish species. The goliath grouper is regarded as pacific and curious fish, but frequently display agonistic behavior in the presence of divers. Based on the perception of well experienced spear fishermen, we hypothesize that E. itajara undertakes seasonal migrations from the inner to the outer bay during summer, and that the studied population is suffering from growth over-fishing. Our data provides a practical evidence of how joining scientific and local ecological knowledge will likely benefit E. itajara local conservation and management practices by adding important new biological data into the decision-making process.

Silage has been widely used in dairy production. However, little is known about its use at production level. The goal of this study was to characterize production and usage of silage for the dairy farming in Western Santa Catarina state. Thirty farms were selected randomly by their geographical location, in 11 municipalities of the West of Santa Catarina state, and they were invited to participate in the research. Out of these 30 farms, 6 did not have any dairy activity, and 2 preferred not to participate in the research, thus were not included. Semi-structured interviews and on-site visits were then performed. All data were analyzed with the software R version 3.2.2. 95% of the farmers produced and fed silage to animals. Out of the 22 farmers participating in the study, 82% provided silage for dairy cows during the whole year; in 86% of these farms, the silage was fed right after milking, in an average amount of 6.06 ± 0.63 kg DM (dry matter) AU-1 (animal unit, 500 kg) day-1. The average area used for maize production was 8.46 ha, representing 59% of the area destined to dairy farming. The average silage production was 8.8 and 7.6 t ha-1 year-1 in the season and off-season crop respectively, without significant differences. In most silage production areas, the no-tillage system is adopted, with the use of pesticides, chemical fertilization and transgenic seeds, without soil covering or crop rotation. Farms that fertilized maize based on soil analysis had the greatest silage yield, compared to the ones that fertilized without relying on soil analysis. The use of different types of pesticides and fertilizer quantities was not correlated to the silage production volume. Overall the production systems and the quantity of silage produced and fed to the cows do not follow technical criteria; thus silage yield and use could be improved if following strategies to better allocate crop inputs.

Abstract The presence of catfish of the Ariidae family in the list of endangered species of Rio Grande do Sul (RS), as from 2014, led to forbidding fishing two species of this family. Thus, artisanal fisherfolk lost a significant part of their income, causing conflicts between them and the fishing authorities in RS. This work aims mainly to understand the Local Ecological Knowledge (LEK) of the artisanal fisherfolk of the North Coast of RS regarding the ecology and taxonomy of catfish of the Ariidae family, seeking to relate it to the establishment of the fishing regulations in force in the State. 33 semi-structured interviews were made with artisanal fisherfolk. The interviewees perceive differences among the region ethnospecies; hardly ever are they consulted during the fishing regulations establishment process. Considering the aforementioned aspects, the artisanal fisherfolk LEK on catfish can be an important tool in the participatory management of catfish fishing.

AbstractSeveral coastal communities rely heavily on wild-caught fish for personal consumption and their livelihoods, thus being sensitive to the rapid global change affecting fish availability. However, in the last century, aquaculture has been increasingly adopted. To understand the uses and changes of wild-caught fish, we conducted 30 semi-structured interviews with fishers of Laguna Lake, Philippines. Fishermen, with up to 60 years’ experience, reported catching 31 fish species as a staple food. The taxa with the greatest variety of food uses were the farmed Oreochromis aureus, and the wild Channa striata and Cyprinus carpio. Fish was boiled, fried, grilled and dried, and over 20 different local dishes were reported. Fishers reported that local communities previously relied more on wild fish, while today a greater proportion of consumed fish comes from aquaculture fish species such as Oreochromis aureus and Hypophthalmichthys nobilis. Wild fish remains a crucial aspect of local gastronomic diversity, underpinning the biodiversity of the Laguna Lake, while also representing an important element for food sovereignty. The study stresses the need to sustain local ecological knowledge to ensure the ecological, social and economic sustainability of the communities.

Abstract BackgroundThe use of plants in rituals is a little explored corner of biocultural diversity which has developed through time within a complex socio-ecological system. Indeed, rituals are complex interactions between humans and biodiversity shaped by history, culture and ethnic belonging. Yet, in Western Ukraine, such rituals were forbidden for over 50 years (1939-1991). The current revival of rituals by rural inhabitants is an untapped reservoir of local ecological knowledge. The aim of the present study was to identify the ritual use of wild and cultivated plants in two regions of Western Ukraine, Bukovina and Roztochya, and to compare the findings with historical data. Moreover, we analyzed attitudes toward the ritual use of plants and interactions with the local environment. MethodsWe conducted 31 in-depth semi-structured interviews among Orthodox Hutsuls of Bukovina and 16 interviews among Greek Catholic rural inhabitants of Roztochya during summer 2018 focusing on the ritual uses of plants. ResultsWe documented 26 plant taxa among Bukovinian Hutsuls and 58 plant taxa among inhabitants in Roztockya that were used in 7 religious festivals (of which two were celebrated differently in the two communities). Plants were mainly used in bouquets, but also for decorating churches and houses or in fruit baskets. In both communities, almost 25% of the interviewees could not name the plants they collected for bouquets, but rather referred to “just beautiful green herbs” one can get in meadows, forests and gardens. Comparison with historical data shows a smaller number of taxa currently used (wild taxa have been lost), yet the persistence of 18 taxa used both now and a century ago. ConclusionsContemporary practices concerning the use of plants in Christian rituals in Bukovina and Roztochya can be contextualized in the broader phenomenon of the revitalization of traditional environmental knowledge and practices that have characterized Europe over the past thirty years and in particular Eastern Europe after socialism. The current religious use of plants is to a certain extent the revitalization of historical rituals supported by various internal (knowledge from older generations) and external (church authorities and fashion in the region) drivers. Further research should address changes in regions with longer and more severe prohibition of religious practices and their revival.

Abstract BackgroundInitiatives for the promotion and intensification of beekeeping through the introduction of modern beehives are taking place in East Africa and elsewhere where beekeeping has been a long-standing livelihood practice. When innovations are introduced into people’s livelihoods and culture, they can trigger multiple changes, aligned or not with the original intentions. We carried out fieldwork in the Eastern part of the Mau Forest Complex, focusing on beekeeping activities among Ogiek beekeepers involved in a project aimed at promoting honey production through the modernization of the apiculture sector. The main aim of the study was to explore the relationships, tensions and complementarity of traditional and modern knowledge and practices and the ways in which they are employed in beekeeping strategies among the Ogiek, as well as to reflect on the changes that this intensification process triggers in the livelihoods of the Ogiek and in their relationship with Mau ForestMethodsWe conducted semi-structured interviews and free listing exercises with 30 Ogiek beekeepers. Other methods included guided field walks in apiaries and participant observation. We collected ethnobotanical data about the flora used in beekeeping and ethnographic information on traditional practices of apiary management and honey harvesting and storing.Results We report 66 species that are important for beekeeping purposes in 6 main use categories, namely melliferous species, and species used for making hives, placing hives, attracting bees, harvesting and storing honey. Our study reveals that the Ogiek still possess detailed knowledge of the forest’s flora and its importance and uses. At the same time, they have moved beekeeping out of the forest into open areas of pasture and crop fields, adopting modern beekeeping techniques. The two beekeeping systems have complementary roles in the livelihoods of the Ogiek and rely on different paths of knowledge transmission and on different plant species. We highlight that modern and traditional beekeeping respond to the challenges and requirements of different ecological settings.ConclusionsOur study indicates a complementarity of traditional and modern beekeeping and associated knowledge and practices within the livelihoods of the Ogiek, but it also suggests that the process of honey production intensification, by decoupling beekeeping from the forest, may weaken the relationship between the Ogiek and the forest, thus impairing the Ogiek’s role as guardians of the forest, and eroding beekeeping-associated TEK. Further studies should target the promotion of forest beekeeping via the intensification of log hive production and valorisation of forest honey and associated TEK as well as floristic diversity.

The invasion of marine species is a threat to local and global biodiversity and can have many ecological, economic and social impacts. The bivalve Isognomon bicolor has invaded the rocky shores of Brazil and spread along the coast, occurring from Rio Grande do Norte to the Santa Catarina State. The present study evaluated the distribution of I. bicolor on different rocky shores of Arvoredo Island (Santa Catarina State) and its relationship with other taxa. A high density of I. bicolor was found on the exposed shore, which was associated with the occurrence of articulated calcareous macroalgae. In addition, I. bicolor was also found in empty shells of the barnacles Tetraclita stalactifera and Megabalanus spp. The physical structure of these habitats probably plays an important role in the success of I. bicolor invasion. For these reasons, I. bicolor evidences an alteration on the benthic community of the rocky shores and its potential consequences become a threat to local species.

European immigrants —and those mixed with native people called caboclos— keep in Southern Brazil therapeutic peculiarities derived from the experience with the biodiversity present in highland fields ecosystems, associated with araucaria forests. The study systematized the popular knowledge about herbal medicine practices adopted by family farmers in the South Plateau of Santa Catarina State. Semi-structured interviews were adopted for the collection of information. Also, indices were adopted as estimates. The knowledge of medicinal plants shared by family farmers of the region appears as a sociocultural heritage, which is still present in rural communities in spite of land changes and alterations in land use.
