Female Social Dominance Does Not Establish Mating Priority in Nile Tilapia
Revista de Etologia 2004, Vol.6, N°1,Social 33-37 dominance and mating in the Nile tilapia Female Social Dominance does not Establish Mating Priority in Nile Tilapia ELIANE GONÇALVES-DE-FREITAS AND ALINE CHIMELLO FERREIRA Universidade Estadual Paulista, São José do Rio Preto Female dominance and size are important features for mating choices in fishes. As dominants are also the largest females in some species, we tested whether dominance per se favours mating priority in Nile tilapia females. Three matched-size adult females (n = 13) were grouped in a 140 l-aquarium during 3 days for hierarchical settlement. On the 4th day a male larger than the females was introduced in the group and kept there for 12 consecutive days until reproduction. Spawning occurred in 8 out of 13 replicates, and the alpha female was the first to mate in only 50% of the cases. Males may thus choose females according to size and not according to rank, as occurs in other cichlid species. As confrontations and the establishment of hierarchical dominance involve high energetic expenditure in Nile tilapias, the reason why females invest in such behaviors is still a question to be elucidated. Index terms: Reproductive behavior. Mate choice. Nile tilapias. Oreochromis niloticus. A dominância social da fêmea não promove prioridade de acasalamento em fêmeas de tilápia-do-Nilo. A dominância e o tamanho da fêmea são características importantes para a escolha do parceiro sexual em peixes. Como as fêmeas dominantes também são as maiores em várias espécies, procuramos verificar se a dominância em si promove a prioridade de acasalamento em fêmeas de tilápia-do-Nilo. -

The new species differs from its congeners by having more branched rays in anal fin (9 /2 vs. 7-8 /2 1 in T. micagemmae and 8 /2 in T. albonubes and T. thacbaensis). Morphological and genetic characters suggest it to be closer related to T. micagemmae, the only other species of Tanichthys known from Central Vietnam. Tanichthys kuehnei differs from T. micagemmae by having a white anal-fin margin (vs. red). Introduction genus Tanichthys inhabit moderately large to very small streams, with populations frequently being Cyprinid fishes of the genus Tanichthys are small restricted to very small geographic areas and are (maximum 33 mm SL) but colourful and well- often found only very locally (Freyhof & Herder, liked by ornamental fish hobbyists. The genus is 2001), leading to strong isolation effects between characterised by confluent narial openings that are the populations. This isolation was demonstrated not separated by a skin wall and by males bear- in a genetic study by Luo et al. (2015) where each ing cornified tubercles on the snout posterior to of six analysed wild populations of T. albonubes premaxilla (Freyhof & Herder, 2001). -

Of these seven, only Ictalurus furcatus (blue catfish), Leuciscus idus (ide), Morone saxatilis (striped bass) and Silurus glanis (Wels catfish) were identified as likely to have a high impact.

Testing the potential of environmental DNA methods for surveying Lake Tanganyika's highly diverse fish communities Christopher James Doble A thesis submitted for the degree of Doctor of Philosophy Department of Genetics, Evolution and Environment University College London April 2020 1 Declaration I, Christopher James Doble, confirm the work presented in this thesis is my own. Where information has been derived from other sources, I confirm this has been indicated in the thesis. Christopher James Doble Date: 27/04/2020 2 Statement of authorship I planned and undertook fieldwork to the Kigoma region of Lake Tanganyika, Tanzania in 2016 and 2017. This included obtaining research permits, collecting environmental DNA samples and undertaking fish community visual survey data used in Chapters three and four. For Chapter two, cichlid reference database sequences were sequenced by Walter Salzburger’s research group at the University of Basel. I extracted required regions from mitochondrial genome alignments during a visit to Walter’s research group. Other reference sequences were obtained by Sanger sequencing. I undertook the DNA extractions and PCR amplifications for all samples, with the clean-up and sequencing undertaken by the UCL Sequencing facility. I undertook the method development, DNA extractions, PCR amplifications and library preparations for each of the next generation sequencing runs in Chapters three and four at the NERC Biomolecular Analysis Facility Sheffield. Following training by Helen Hipperson at the NERC Biomolecular Analysis Facility in Sheffield, I undertook the bioinformatic analysis of sequence data in Chapters three and four. I also carried out all the data analysis within each chapter. Chapters two, three and parts of four have formed a manuscript recently published in Environmental DNA (Doble et al. -
