Fish movement is usually associated with reproduction, feeding, escaping predators or dispersing to new habitats. This occurs between marine and freshwater habitats, and wholly within freshwater. Obstacles to this movement, such as stream crossings, can severely deplete fish populations, including recreational and commercial species such as barramundi, mullet, Mary River cod, silver perch, golden perch, sooty grunter and Australian bass. Many Queensland streams are ephemeral (they may flow only during the wet season), and therefore crossings must be designed for both flood and drought conditions.

Saifullah Bin Aziz a, Neaz A. Hasan b, Md. Mostafizur Rahman Mondol a, Md. Mehedi Alam b, Mohammad Mahfujul Haque b,* a Department of Fisheries, University of Rajshahi, Rajshahi, Bangladesh b Department of Aquaculture, Bangladesh Agricultural University, Mymensingh, Bangladesh ARTICLE INFO ABSTRACT Keywords: This study evaluates changes in fish species diversity over time in Hakaluki Haor, an ecologically critical wetland Haor in Bangladesh, and the factors affecting this diversity. Fish species diversity data were collected from fishers using Fish species diversity participatory rural appraisal tools and the change in the fish species diversity was determined using Shannon- Fishers Wiener, Margalef's Richness and Pielou's Evenness indices. Principal component analysis (PCA) was conducted Principal component analysis with a dataset of 150 fishers survey to characterize the major factors responsible for the reduction of fish species Climate change fi Anthropogenic activity diversity. Out of 63 sh species, 83% of them were under the available category in 2008 which decreased to 51% in 2018. Fish species diversity indices for all 12 taxonomic orders in 2008 declined remarkably in 2018. The first PCA (climatic change) responsible for the reduced fish species diversity explained 24.05% of the variance and consisted of erratic rainfall (positive correlation coefficient 0.680), heavy rainfall (À0.544), temperature fluctu- ation (0.561), and beel siltation (0.503). The second PCA was anthropogenic activity, including the use of harmful fishing gear (0.702), application of urea to harvest fish (0.673), drying beels annually (0.531), and overfishing (0.513).

  • Systematic Taxonomy and Biogeography of Widespread
    Systematics and Biogeography of Three Widespread Australian Freshwater Fish Species. by Bernadette Mary Bostock B.Sc. (Hons) Submitted in fulfilment of the requirements for the degree of Doctor of Philosophy Deakin University February 2014 i ABSTRACT The variation within populations of three widespread and little studied Australian freshwater fish species was investigated using molecular genetic techniques. The three species that form the focus of this study are Leiopotherapon unicolor, Nematalosa erebi and Neosilurus hyrtlii, commonly recognised as the three most widespread Australian freshwater fish species, all are found in most of the major Australian drainage basins with habitats ranging from clear running water to near stagnant pools. This combination of a wide distribution and tolerance of a wide range of ecological conditions means that these species are ideally suited for use in investigating phylogenetic structure within and amongst Australian drainage basins. Furthermore, the combination of increasing aridity of the Australian continent and its diverse freshwater habitats is likely to promote population differentiation within freshwater species through the restriction of dispersal opportunities and localised adaptation. A combination of allozyme and mtDNA sequence data were employed to test the null hypothesis that Leiopotherapon unicolor represents a single widespread species. Conventional approaches to the delineation and identification of species and populations using allozyme data and a lineage-based approach using mitochondrial 16S rRNA sequences were employed. Apart from addressing the specific question of cryptic speciation versus high colonisation potential in widespread inland fishes, the unique status of L. unicolor as both Australia’s most widespread inland fish and most common desert fish also makes this a useful species to test the generality of current biogeographic hypotheses relating to the regionalisation of the Australian freshwater fish fauna.

The earliest observation occurred in 1974 and the last observation occurred in 1984. From Nico and Neilson (2018): “Failed in Florida.” This species is in trade in the United States.

  • Molecular Phylogeny of Philippine Tigerperches (Perciformes: Terapontidae) Based on Mitochondrial Genes
    Philippine Journal of Science 148 (S1): 251-261, Special Issue on Genomics ISSN 0031 - 7683 Date Received: 18 Mar 2019 Molecular Phylogeny of Philippine Tigerperches (Perciformes: Terapontidae) Based on Mitochondrial Genes Reynand Jay C. Canoy1,2,3, Ian Kendrich C. Fontanilla1,2, and Jonas P. Quilang1,2* 1Natural Sciences Research Institute, University of the Philippines Diliman, Quezon City 1101 Philippines 2Institute of Biology, College of Science, University of the Philippines Diliman, Quezon City 1101 Philippines 3Institute of Human Genetics, National Institutes of Health University of the Philippines Manila, 625 Pedro Gil St., Ermita, Manila 1000 Philippines The molecular phylogeny of the Philippine tigerperches is first described in this study. Eight species were analyzed: these include one endemic species (Leiopotherapon plumbeus); one introduced species (Bidyanus bidyanus); and six native species (Terapon jarbua, Terapon puta, Terapon theraps, Pelates quadrilineatus, Helotes sexlineatus, and Mesopristes cancellatus). Primers were designed to amplify and sequence the 12S rRNA (12S), cytochrome c oxidase subunit I (COI), and cytochrome b (CytB) genes. The concatenated 12S, COI, and CytB sequences (3529 bp) were used to construct the phylogeny of the tigerperches using Maximum Parsimony (MP), Neighbor Joining (NJ), Maximum Likelihood (ML), and Bayesian Inference (BI) analyses. All four analyses supported the monophyly of tigerperches. Except for the MP tree, all phylogenetic trees showed that Terapon jarbua was the first to have diverged from the rest of the tigerperch species examined. The congeneric T. jarbua, T. puta and T. theraps did not group together, suggesting their non-monophyly. However, SH test on the unconstrained (actual observation) and constrained (the three congeneric species were forced to group together) NJ trees showed no significant difference (p = 0.55).

The major forces behind the loss of biodiversity in freshwater are habitat degradation and fragmentation, increased sedimentation, exotic Naresh Lavudya species introduction, water abstraction, over-harvesting, pollution, and global climate change impacts. College of Fisheries Science, The diversity of Freshwater fish in the River Narmada and its tributaries in the central state of Madhya Junagadh Agricultural Pradesh has been reviewed. A total of 176 species from fresh water habitats out of which 13 orders, 46 University, Veraval, Gujarat, families, 107 genera, and 176 species. The order Cypriniformes represented the highest diversity with 79 India species followed by Perciformes (35 species), Siluriformes (32 species), Clupeiformes (11 species), etc. This review presents up-to-date information on freshwater fish diversity of the River Narmada. Freshwater fish diversity information could also provide a baseline for future more complex ecological studies, and planning the conservation and sustainable use of inshore inland water resources. Keywords: Freshwater diversity, Major issues, River Narmada Introduction All over India, freshwater fish diversity is on a decline.
