Maximum Body

Megafishes are important to people and ecosystems worldwide. These fishes attain a maximum body weight of ≥30 kg. Global population declines highlight the need for more information about megafishes’ conservation status to inform management and conservation. The northern Cambodian Mekong River and its major tributaries are considered one of the last refugia for Mekong megafishes. We collected data on population abundance and body size trends for eight megafishes in this region to better understand their conservation statuses. Data were collected in June 2018 using a local ecological knowledge survey of 96 fishers in 12 villages. Fishers reported that, over 20 years, most megafishes changed from common to uncommon, rare, or locally extirpated. The most common and rarest species had mean last capture dates of 4.5 and 95 months before the survey, respectively. All species had declined greatly in body size. Maximum body weights reported by fishers ranged from 11–88% of their recorded maxima. Fishers identified 10 threats to megafishes, seven of which were types of illegal fishing. Electrofishing was the most prevalent. Results confirm that Mekong megafishes are severely endangered. Species Conservation Strategies should be developed and must address pervasive illegal fishing activities, alongside habitat degradation and blocked migrations, to recover declining populations.

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.

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.
