Freshwater species are the most threatened group to be assessed to date by the IUCN. Freshwater fish has enormous importance as animal protein supplies for human, and it is estimated that 6% of the world annual animal protein supplies come from freshwater fishes. Barcoding projects have been initiated all over the world and the field is constantly growing. In Malaysia however, the field has not been deeply investigated and not many barcoding projects have been undertaken especially for freshwater fishes. The aim of our study is to support the progress of DNA barcode project, especially for inland reservoirs like Tasik Raban, Perak. A Standard methodology using Cytochrome c oxidase subunit 1 (COI) marker was developed to ensure native fishes are barcoded taxonomically and molecularly and ready to be accessed through online databases. Such public references can help increase awareness on local fish diversity management. Information on taxonomy and molecular characterization can be used to plan further conservation programmed especially for depleted, unrecognized, and cryptic native species.

Assessment And Monitoring

In this study, we provide a first estimation of the molecular diversity of the freshwater fishes of Georgia. In addition to field collections, we integrated DNA barcode data obtained from recent works and public databases (BOLD and NCBI GenBank). Currently, the DNA barcode reference library for freshwater fishes of Georgia comprises 352 DNA barcodes for 50 species, 36 genera and 15 families (52% of total Georgian freshwater fish diversity), from which 162 DNA barcodes belonging to 41 species were newly generated as part of this study. A total of 22 species are reported from the Caspian Sea basin and 31 from the Black Sea basin. Amongst the studied taxa, seven species were found with large interspecific divergences (> 2%) while 11 species were found to share DNA barcodes within our dataset. In the course of the study, we found the first evidence of the existence of Gymnocephalus cernua (Linnaeus, 1758) and also confirm the second occurrence of invasive Rhinogobius lindbergi (Berg, 1933) in Georgia. Based on the evaluation of currently-available barcode data for Georgian fishes, we highlighted major gaps and research needs to further progress DNA-based biodiversity studies in Georgia. Though this study lays a solid base for DNA, based biodiversity assessment and monitoring approaches, further efforts within the recently started CaBOL (Caucasus Barcode Of Life) project are needed to obtain reference data for the species still lacking DNA barcodes.

AbstractWith 1172 native species, the Indonesian ichthyofauna is among the world’s most speciose. Despite that the inventory of the Indonesian ichthyofauna started during the eighteen century, the numerous species descriptions during the last decades highlight that the taxonomic knowledge is still fragmentary. Meanwhile, the fast increase of anthropogenic perturbations during the last decades is posing serious threats to Indonesian biodiversity. Indonesia, however, is one of the major sources of export for the international ornamental trade and home of several species of high value in aquaculture. The development of new tools for species identification is urgently needed to improve the sustainability of the exploitation of the Indonesian ichthyofauna. With the aim to build comprehensive DNA barcode libraries, the co-authors have started a collective effort to DNA barcode all Indonesian freshwater fishes. The aims of this review are: (1) to produce an overview of the ichthyological researches conducted so far in Indonesia, (2) to present an updated checklist of the freshwater fishes reported to date from Indonesia’s inland waters, (3) to highlight the challenges associated with its conservation and management, (4) to present the benefits of developing comprehensive DNA barcode reference libraries for the conservation of the Indonesian ichthyofauna.

Close Relatives

We used phylogenetically based comparative analyses to test for associations between extinction risk in European freshwater fishes and a variety of life history, ecological, and biogeographical traits. Based on the World Conservation Union classification scheme, a total of 47% of Europe's 287 native species are classified as threatened with extinction. Threatened species are significantly smaller than less-threatened species in the same genera when analyses are restricted to fully freshwater species. This trend is reversed when anadromous genera are included. These comprise many large-bodied species in which fishing has often played a greater role in declines than in other taxa. Threatened species did not differ significantly in their habitats, although they tended to occupy a narrower variety of habitats biased toward streams and rivers. Threatened species occupy much narrower latitudinal ranges than close relatives that are less threatened, and they also have more southerly distributions where pressures on habitats are intense. This study suggests that links between life histories and threat status of freshwater fishes are not as clearcut as for marine species. For fish restricted entirely to freshwater, small-bodied species are most at risk owing to their naturally small ranges, which may put them in a more precarious position when their habitats are impacted by humans.

The Impact

Delighting consumers has been one of the most important goals for marketing stakeholders but the effect of historical nostalgia on tourists delight at the world cultural heritage sites has rarely been examined. This study examines the impact of historical nostalgia on the heritage tourists' delight, their satisfaction and destination loyalty intention. The survey for the study was conducted at the world cultural heritage site of Mahabalipuram, India. The hypotheses were tested through the structural equation modelling technique. The results indicated positive and significant effect of historical nostalgia on tourists' delight, satisfaction and destination loyalty intention. The study makes contribution to the tourism studies by examining the role of historical nostalgia in delighting the tourists at the cultural heritage sites and instructs the managers to evoke such experiences to keep the heritage tourists delighted and thereby enhance their loyalty.

Abstract The South America ichthyofauna encompasses the highest diversity of the world, however is highly threatened by anthropogenic actions. The fish fauna of nine low-order streams, tributaries of the Piquiri River and impacted by aquaculture, agriculture and urbanization were sampled in the present study. Samplings were done quarterly from December 2017 to September 2018 at three sites in each stream, using a portable electric fishing device in 50-meter segments. A total of 14,507 individuals were collected, belonging to six orders, 20 families, 46 genera, and 70 species. The highest richness and abundance were found for the orders Characiformes and Siluriformes. In this study, nine species that had not been recorded were found, totaling 163 for the basin. In addition, 14 non-native species were captured. The presented list of species contributes to the existing database of ichthyofauna distribution in Neotropical streams, denoting that it is underestimated in the region, mainly in low-order tributaries. The present study reinforces the importance of inventories and monitoring in environments with high biodiversity and sensitive to anthropogenic actions.
