The localization STELLINGEN 1. Er zijn geen argumenten voor de veronderstelling dat bij juveniele en adul­ te maagloze vissen de eiwitvertering in het darmlurnen minder effektief zou zijn dan bij maaghoudende soorten. Dit proefschrift. 2. De opvatting van Trevisan, dat vooral het caudale deel van de graskarper- darm betrokken is bij de resorptie van nutriënten, is onjuist en komt voort uit het trekken van voorbarige konklusies uit alleen morfologische informatie. Trevisan, P. : Anat. Anz. 145, 237-248 (1979). 3. Het voorstel van Green & Phillips, graanmutanten te kweken met verminderde feedbackinhibitie van aspartaatkinase door lysine en threonine, om zo het ge­ halte aan één of meer aminozuren uit de aspartaat-familie te vergroten, verdient stellig waardering maar lijkt geen praktische bijdrage tot de oplossing van het wereldvoedselvraagstuk te kunnen leveren. Green, CE. &Phillips , R.L. : Crop Science 14, 827-829 (1974). 4. De circadische fluktuaties in gevoeligheid van diverse weefsels voor bepaal­ de hormonen suggereert dat hormoonreceptoren een korte levensduur hebben. Meier, A.H. ; John, T.M. &Joseph , M.M. : Comp. Biochem. Physiol. 40A, 459-465 (1971). Meier, A.H. ; Trobec, T.N. ; Joseph, M.M. &John , T.M. : Proc. Soc. Exp. Biol. and Med. 37, 408-415 (1971). 5. De isolatie van zowel één glycoproteinerijk- als één glycoproteinearm gona- idotroop hormoon uit hypofyses van beenvissen ondersteunt de opvatting dat "glo­ bulaire" en "vesiculaire" P.A.S.- positieve gonadotrope cellen tot hetzelfde (celtype behoren, maar sluit niet uit dat er een tweede gonadotroop celtype, mo­ gelijk niet P.A.S.- positief, aanwezig is.

Ueda, H. : Bull. Fac. Fish. Hokkaido Univ. 31, 1-15 (1980). 6. Het zou van groot belang voor de wereldvrede kunnen zijn, onderzoek te ver­ richten naar de oorzaken van het verschijnsel dat achteruitgang van de levens­ standaard veelal leidt tot toename van onredelijk vijand-denken en stijgende wa- penproduktie, en in dit verband onder andere aandacht te schenken aan de moge­ lijke rol van het "Militair Industrieë'el Komplex" . 7. De boycot van de Olympische Spelen in Moskou, waarvoor de verschillende re­ denen op zichzelf terecht werden aangevoerd, doet vermoeden dat wij, wester­ lingen, het restant van de boterberg die aan de Sovjetunie is verkocht op ons hoofd hebben gesmeerd in plaats van ook onszelf boter op het brood te geven. 8. De "vertrossing" van de omroepen leidt er toe dat de afleiding die wordt gebracht de bevolking afleidt van de meest wezenlijke problemen van onze samen­ leving. 9. Het feit, dat de vervoersorganisaties bezwaar maken tegen het gebruik van "hun" belastinggelden ten behoeve van de aanleg van fietspaden betekent dat de wegvervoerders te weinig oog hebben voor de fietsende medemens en onderstreept derhalve de noodzaak van genoemde wielerpaden. 10.De "brede maatschappelijke discussie" over kernenergie zal, wanneer het ka­ binet zich niet onthoudt van voorbarige uitspraken, vergelijkbaar blijken met een golfstroom : oeverloos en met voorspelbare bestemming.

  • Adaptive Modification of Lip and Its Associated Structures of Hill- Stream Fish Schizothorax Richardsonii (Cypriniformes: Cyprinidae)
    IOSR Journal of Pharmacy and Biological Sciences (IOSR-JPBS) e-ISSN: 2278-3008. Volume 5, Issue 4 (Mar. – Apr. 2013), PP 59-65 www.iosrjournals.org Adaptive modification of lip and its associated structures of Hill- stream fish Schizothorax richardsonii (Cypriniformes: Cyprinidae). Hoshiyar Singh1, S.C. Joshi2, Ila Bisht1 and S.K. Agarwal1 1. Department of Zoology, S.S.J. Campus Almora, Kumaun University Nainital, 263601, India. 2. Department of Zoology, Surajmal Agarwal Girls, P.G. College Kichha, K.U. Nainital, 263145. Abstract: The lips and associated structures, in different groups of fishes, are greatly modified in relation to the characteristic mode of feeding, food preference and the mode of life exhibited by the fish. The successful maintenance of fish populations in challenging environments requires responsive adjustments in their behaviour, morphology and physiology and these have been reflected by modifications at the level of their organ systems, organs and tissues. The lips are no exception to this. The importance of food in daily life of a fish is obvious and is reflected in the form of the mouth, lips, jaw and so on. These structures present more diverse modifications than any other organ of the body. The functional aspects of the lips and associated structures in family Gobiidae, Cobitidae, Belontiidae and few species of Cyprinidae show considerable variation and exhibit unique morphological modifications associated with their lips and other structures around the mouth regarding information on the level of surface architecture as seen under SEM in relation to various food and feeding habits and ecological niches. Key words: Cyprinidae, fishes, lip and morphology.

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.

  • Genetic Diversity, Evolutionary Relationships and Conservation of Southern African Labeo Fishes in Relation To
    Genetic diversity, evolutionary relationships and conservation of southern African Labeo fishes in relation to water management A thesis submitted in fulfilment of the requirements for the degree of DOCTOR OF PHILOSOPHY of RHODES UNIVERSITY by MPHO RAMOEJANE October 2016 ABSTRACT Labeo spp. are large, herbivorous fishes that are important components of aquatic ecosystems and are a high conservation priority in South Africa. This thesis contributes to determination of conservation priorities for Labeo umbratus (Smith 1841) by resolving the taxonomic status of this species in the evolutionary context of southern African Labeo spp., assessing the presence of unique lineages in historically isolated river basins, and assessing the threat of intra- and interspecific hybridisation associated with introductions. Phylogenetic analyses of five DNA sequence data sets (cytochrome c oxidase subunit I gene [COI], cytochrome b gene [Cyt b], Recombination activating gene 1 [Rag1], COI+Rag1 and COI+Cyt b+Rag1) showed that the Labeo umbratus group (sensu Reid, 1985), which comprises the species Labeo umbratus, Labeo capensis (Smith 1841), Labeo seeberi Gilchrist and Thompson 1911 and Labeo rubromaculatus Gilchrist and Thompson 1913, is monophyletic, morphologically distinct and geographically disjunct from other African Labeo spp. groups except in the Tugela River system were L. rubromaculatus co-occurs with Labeo molybdinus Du Plessis 1963. Phylogeographic analysis of mitochondrial DNA (Cyt b) sequence data demonstrated that the populations of the L. umbratus from the Orange and the southward-flowing river systems are reciprocally monophyletic and were identified as evolutionary significant units. The populations in the southward-flowing river systems were further divided into southwestern (Gourits and Gamtoos) and southeastern (Sundays, Bushmans, Great Fish, Keiskamma, Buffalo and Nahoon) polyp hyletic sublineages.

Box 1176, Addis Ababa, Ethiopia OPEN ACCESS 3 Agriculture and Environment Division (AED), Inter-Governmental Authority on Development (IGAD), Djibouti A) 1 [email protected] (corresponding author), 2 [email protected], 3 [email protected] Abstract: The reproductive biology of Garra regressus and Garra tana was investigated by collecting monthly samples (January to December 2006) from the southern Gulf of Lake Tana, where these species are endemic. Garra regressus has an extended breeding time from April to October while G. tana breeds throughout the year with a peak from March to July. The mean size at maturity in both the species was not significantly different between the sexes, but G. tana had a significantly lower mean size at maturity than G. regressus in female specimens. Absolute fecundity estimates for G. regressus ranged from 580.8–1800, while those for G. tana ranged from 538.9–2968. Egg size frequency distribution revealed thatG. regressus is a multiple spawner, whileG. tana is a single spawner. The sex ratio in the total catch of G. regressus was found to be skewed in favour of females (Chi-square, P< 0.05), while those for G.
