Abstract This study characterizes the gill net fishery at Colônia de Pescadores Z13 (CPZ13), in Copacabana, Rio de Janeiro, and its relationship with the marine protected area ‘Monumento Natural do Arquipélago das Ilhas Cagarras – MoNa Cagarras’, describing the fleet and fishing gears, identifying fishing spots, species and their associations by gillnet type. From June 2012 to May 2013, every Tuesday to Sunday, gill net landings were monitored and fishers interviewed regarding their catch. Small boats (dory whaleboats) are used to set three types of gillnets: “Corvineira” (target species – whitemouth croaker), “linguadeira” (target species – flounders) and “rede-alta” (target species – bluefish). Fifty-nine species within 37 families were captured at 14 fishing spots, showing association with bottom type and distance from shore. The use of fisher’s local ecological knowledge defines gear placement at specific sites targeting fisheries resources. All fishing sites are not within the limits of MoNa Cagarras but would benefit from management plans including an MPA buffering zone.

In The Beginning

An understanding of the effects of fishing on marine ecosystems relies on information about the conserved state of these environments. Non-conventional approaches such as the use of historical data and local ecological knowledge can provide information and help adjust our references of changes in the environment. Also, the combination of different types of data can indicate a fisheries trend that would be undetectable when evaluated separately. Here we investigated changes in fisher’s perceptions regarding overexploited and new target species in artisanal fisheries in a secular fishing village of the subtropical, southeastern Brazilian coast. We identified temporal changes in landings and in the mean trophic level (MTL) of high trophic level species (≥ 3.5 and >4) over 16 years. Fishers’ knowledge revealed shifts in perception associated with years of fishing practice. More experienced fishers recognized a greater number of overexploited and new target species than fishers in the beginning of their careers. Landing data has revealed declining trends of 72% for five mesopredators species. Due to the overfishing of mesopredators, there was a shift in target species, towards fish that were previously discarded. Temporal changes in landings and in the MTL metric are concordant with previous reports on the overexploitation of species caught by local fishers. Our work reveals that multiple sources of information can be combined to establish historical baselines and improve the detection of change in marine ecosystems.

New Perspective

This study aims at evaluating the environmental education (EE) and communication intervention for the valorization of migratory fish resources in an estuary of northern Portugal. The EE component intervention was implemented among Middle School pupils of that region. Students’ knowledge was quantitatively evaluated with an experimental approach of pre-testing and post-testing, on the ocean and estuarine literacy (OEL) and biology of migratory species, such as sea lamprey. This study also analyzes the communication component developed via social media. Results of the EE component show an evident increment of OEL (p < 0.05). It is also highlighted that students had previous knowledge on issues that are not covered in the curriculum. Social media has shown to be an effective communication tool mostly among the scientific community (e.g., Ethnobiology). The research has various implications to OEL since it brings a new perspective towards the integration of ocean literacy in formal education; as well as the valorization of Students’ local ecological knowledge and of inter-generational dynamics. This study contributed to promoting local biodiversity, OEL, and participatory local governance of these ecosystems.

AbstractDue to global change and the migration crisis both needing rapid attention, there has been growing debate about the drivers of change in the diet of migrants. Our study aimed to evaluate the consequences of forced resettlement on local ecological knowledge related to wild food plants among forcefully resettled Yaghnobi people in Tajikistan. We conducted 49 semi-structured in-depth interviews and recorded 27 wild food taxa and five unidentified folk taxa used by Yaghnobis and Tajiks in the villages surrounding Yaghnob Valley (including families ressetteled from Yaghnob Valley) in central Tajikitsan. The comparision between the two considered groups showed a high level of Tajikisation among Yaghnobis, both those who live alongside Tajiks as well as those living separately. The few families that still have distinct Yaghnobi plant uses are the ones which were given the opportunity to choose the spot in which to relocate and still visit the Yaghnob Valley regularly. On the basis of our study, we suggest that affording a choice of where to relocate is better than no choice, as the loss of motivation also affects the use of wild food plants. Given the pressure of the possible relocation of many groups of people in the light of global change, we suggest focusing efforts on studying similar cases in order to minimize the damage caused to people by relocation. The trauma of forced relocation, even just a few kilometers away, directly or indirectly affects wild food plant use and with this the food security of the community.
