Endangered Species
FEATURE: ENDANGERED SPECIES Conservation Status of Imperiled North American Freshwater and Diadromous Fishes ABSTRACT: This is the third compilation of imperiled (i.e., endangered, threatened, vulnerable) plus extinct freshwater and diadromous fishes of North America prepared by the American Fisheries Society’s Endangered Species Committee. Since the last revision in 1989, imperilment of inland fishes has increased substantially. This list includes 700 extant taxa representing 133 genera and 36 families, a 92% increase over the 364 listed in 1989. The increase reflects the addition of distinct populations, previously non-imperiled fishes, and recently described or discovered taxa. Approximately 39% of described fish species of the continent are imperiled. There are 230 vulnerable, 190 threatened, and 280 endangered extant taxa, and 61 taxa presumed extinct or extirpated from nature. Of those that were imperiled in 1989, most (89%) are the same or worse in conservation status; only 6% have improved in status, and 5% were delisted for various reasons. Habitat degradation and nonindigenous species are the main threats to at-risk fishes, many of which are restricted to small ranges. Documenting the diversity and status of rare fishes is a critical step in identifying and implementing appropriate actions necessary for their protection and management. Howard L.

E-mail: [email protected] Abstract The phylogenetic or evolutionary relationships of species of Cypriniformes, as well as their classification, is in a era of flux. For the first time ever, the Order, and constituent Families are being examined for relationships within a phylogenetic context. Relevant findings as to sister-group relationships are largely being inferred from analyses of both mitochondrial and nuclear DNA sequences. Like the vast majority of Cypriniformes, due to an overall lack of any phylogenetic investigation of these fishes since Hennig’s transformation of the discipline, changes in hypotheses of relationships and a natural classification of the species should not be of surprise to anyone. Basically, for most taxa no properly supported phylogenetic hypothesis has ever been done; and this includes relationships with reasonable taxon and character sampling of even families and subfamilies. -

Proceedings of the International Academy of Ecology and Environmental Sciences, 2020, 10(4): 131-143 Article Ichthyofaunal diversity and conservation status in rivers of Khyber Pakhtunkhwa, Pakistan Mukhtiar Ahmad1, Abbas Hussain Shah2, Zahid Maqbool1, Awais Khalid3, Khalid Rasheed Khan2, 2 Muhammad Farooq 1Department of Zoology, Govt. Post Graduate College, Mansehra, Pakistan 2Department of Botany, Govt. Post Graduate College, Mansehra, Pakistan 3Department of Zoology, Govt. Degree College, Oghi, Pakistan E-mail: [email protected] Received 12 August 2020; Accepted 20 September 2020; Published 1 December 2020 Abstract Ichthyofaunal composition is the most important and essential biotic component of an aquatic ecosystem. There is worldwide distribution of fresh water fishes. Pakistan is blessed with a diversity of fishes owing to streams, rivers, dams and ocean. In freshwater bodies of the country about 193 fish species were recorded. There are about 30 species of fish which are commercially exploited for good source of proteins and vitamins. The fish marketing has great socio economic value in the country. Unfortunately, fish fauna is declining at alarming rate due to water pollution, over fishing, pesticide use and other anthropogenic activities. Therefore, about 20 percent of fish population is threatened as endangered or extinct. All Mashers are ‘endangered’, notably Tor putitora, which is also included in the Red List Category of International Union for Conservation of Nature (IUCN) as Endangered. Mashers (Tor species) are distributed in Southeast Asian and Himalayan regions including trans-Himalayan countries like Pakistan and India. The heavy flood of July, 2010 resulted in the minimizing of Tor putitora species Khyber Pakhtunkhwa and the fish is now found extinct from river Swat. -

Rhode Co-supervisor: Dr R. Slabbert Department of Genetics December 2020 Stellenbosch University https://scholar.sun.ac.za Declaration: By submitting this thesis electronically, I declare that the entirety of the work contained therein is my own, original work, that I am the sole author thereof (save to the extent explicitly otherwise stated), that reproduction and publication thereof by Stellenbosch University will not infringe any third party rights and that I have not previously in its entirety or in part submitted it for obtaining any qualification. Date: December 2020 Copyright © 2020 Stellenbosch University All Rights Reserved i Stellenbosch University https://scholar.sun.ac.za Abstract: Labeo spp. are large freshwater fish found throughout southern Asia, the Middle East and Africa. The genus is characterised by specialised structures around the mouth and lips making it adapted to herbivorous feeding (algae and detritus). Clanwilliam sandfish (Labeo seeberi) was once widespread throughout its natural habitat (Olifants-Doring River system), but significant decreases in population size have seen them become absent in the Olifants River and retreat to the headwaters in the tributaries of the Doring River. Currently sandfish are confined to three populations namely the Oorlogskloof Nature Reserve (OKNR), Rietkuil (Riet) and Bos, with OKNR being the largest of the three and deemed the species sanctuary. -

Introduction Contribution of Indigenous Fish in Total Production Is
Workshop Proceedings on Indigenous Fish Stock and Livelihood in Nepal 1 Introduction Contribution of indigenous fish in total production is declining worldwide as most fresh and marine fishes have been over fished (FAO 2008). Previously, many such over fished waters were introduced with non-native fish for providing immediate reliance to fishers through enhancing capture fisheries; and protection of native fish being over exploitation by diverting fisher to non-indigenous species. Details of scientific review might need either those strategies could be fruitful or not. However, recently, more focus has been given to develop the technologies of native fish species for enhancing their fishery and aquaculture from biodiversity perspectives. Knowledge and information on native species from the present perspective has seldom been synthesized and analyzed. Therefore, it is essential to collect the scattered data and prioritize the strategies for sustainable technological generation of these species in the country. The current proposal for organizing a workshop on such a crucial subject would be highly fruitful to give the direction of future research in development of fisheries and aquaculture technologies prioritizing values of indigenous fishes and re-positioning the fisheries and aquaculture to more rewarding, environment friendly, socially acceptable and economically profitable activity. The overall objective of the workshop is aquaculture development of native fish species for biodiversity and aquaculture practices. The symposium would attract the scientific attention on review, cross interaction, situation analysis, planning focused research, intervention program to make fisheries and aquaculture technology of indigenous fishes more competitive and advantageous. To address these issues, technical sessions are planned in following major themes: A. -

Checklist of Fishes of Thunder Bay District, Ontario
Thunder Bay Field Naturalists Checklist of Fish es of Thunder Bay District , Ontario 31 December 2019 Introduction This first edition of Checklist of Fishes of Thunder Bay District adds to existing checklists prepared by members of the Thunder Bay Field Naturalists (TBFN) covering other vertebrate taxa (mammals, birds, reptiles & amphibians), as well vascular plants, butterflies, and odonates. As with these other checklists, it covers the official judicial District of Thunder Bay (Figure 1). The District extends from the eastern border of Quetico Provincial Park east to White River, and from the international border north to Lake St. Joseph and the Albany River. Much of the District (60%) is within the Great Lakes watershed, with the remaining draining into the Arctic Ocean either north via the Hudson Bay Lowlands, or west via Rainy Lake/Lake of the Woods and the Nelson River watershed. Figure 1. Judicial District of Thunder Bay with primary watersheds and protected areas. 2 The fish species of the Thunder Bay District mostly reflect post-glacial colonization, modified by more recent ecological and anthropogenic influences. The Wisconsinan ice mass began to retreat north of Lake Superior circa 10,700 BP (Farrand and Drexler 1985), allowing fish to initially colonize the Thunder Bay area (Momot and Stephenson 1996). The Marquette advance circa 9900 BP likely wiped out these early colonizers, but its retreat around 9700 BP allowed many species access from glacial refugia in the Mississippi River basin to the south (Mandrak and Crossman 1992b; Stephenson and Momot 1994). Some species invaded from the east via the outlet of Lake Minong and Lake Superiors’ other post-glacial predecessors.
