Meeting adjourned for supper at 10.17. vc~ _ B ILAPIA BUTT~KOFERI by Kevin Sorensen When these fish first arrived on the market friends were able to purchase 3 youngsters of what is believed to be the original twenty fish. The young Tilapia were housed in a standard six foot aquarium with other African and American cichlids of similar size. Feeding was not a problem as they ate everything and anything offered, without showing signs of aggressiveness towards the other tank inhabitants other than not allowing them the necessity of eating. Future visits showed that the Buttikoferi were growing at a staggering rate and were now three to four times the size of the other fish, it was becoming very obvious that the continued housing of the Tilapia with the others was no longer viable. They were offered to me for housing in my fish room as more space and larger tanks were available. The offer was quickly accepted and the Tilapia netted and removed before any change of mind could occur. Searches for information in Aquarium publications shed very little light on breeding or their natural environment. What was available showed that Tilapia Buttikorferi is a medium substrate spa~ler with bronze and black vertical barring, irridescent blue lips and body length white pelvic fins. Natural diet consisting almost exclusively of water snails. They are found on the ivory coast of West Africa, inhabiting river systems such as the Aantje River River in Sierra Leone and St. Paul's River, conditions are started at hardness of 50-80 PPM, temperatures of 24 to 25°C and pH ranging between 6.5 - 6.8, with sizes in aquaria of 12" in males and 10" in females being common. Six months and a great deal of food later two of the Butt ikoferi began showing signs of forming a pair. Over the following few weeks the two proceeded to stake out a territory in the centre of the 6 x 2 x 2 tank they were housed in and both constantly harrassed the remaining third Buttikoferi while paying little attention to the other inhabitants except for the usual sparring and gill flaring. 6 Both fish began to clean and excavate a cave between two rocks, the ~ale seemed to lose interest with the preparatioT}s and preferred harrassing the remaining -Buttikoferi, the female would continue digging and cleaning, onlv leaving the ~hosen site to retrieve the male who continued to show less interest in the nrePArAtions. These events continued for two weeks during which time the temperature was increased to 29°e to try and induce the spa~ning. The Tilapia spent more time together but sti11 no sign of the females breeding tube. Unfortunately "~or the remainder of the inhabitants the increase in temperature caused the spawning of a pari of Dovii and Synspilum on either side of the Buttikoferi site, leaving fewer remaining places where peace could be found. One week later with the addition of Epsom salts and cooking salts the Buttikoferi female laid approximately l50 200 tan coloured eggs. The male became a model parent, patroling the site and relieving the female with the fanning of the eggs. Many of the eggs showed signs of being infertile after 48 hours except for a small patch of 25 or 30 of which the eyes of the developing fry could be seen. The rock and developing eggs were removed and placed in a smaller tank, hatching occurred in a further 24 hours at 27°e and pH of 7.4 with hardness at 90 ppm the fry became free swimming in a further 4 days at which time they eagerly accepted microworms and newly hatched brine shrimp. The fry continued to put on size quickly on a diet of grindleworms and prepared foods at f our weeks mosqui toe lavae and white worms could be accepted as well, the young reaching a size of 1 to 1 1/4 inches in 8 to g weeks. Future spawns increased in size and fertility and the adult pair were rehoused in a 48 x 18 x 18 inch tank, filtration was supplied by a side drop filter with twin air uplifts. vc 7 While attending spawns the male would change colour to a sooty black with the light barri~g becoming less noticeable and the checking pattern of t~e dorsal fin became more apparent. The female hecame a brilliant white and black fish which would violently attack the front glass of the tank when anyone approached.

  • Depth Segregation and Diet Disparity Revealed by Stable Isotope Analyses
    Hata et al. Zoological Letters (2015) 1:15 DOI 10.1186/s40851-015-0016-1 RESEARCH ARTICLE Open Access Depth segregation and diet disparity revealed by stable isotope analyses in sympatric herbivorous cichlids in Lake Tanganyika Hiroki Hata1*, Jyunya Shibata2,3, Koji Omori2, Masanori Kohda4 and Michio Hori5 Abstract Background: Lake Tanganyika in the African Great Rift Valley is known as a site of adaptive radiation in cichlid fishes. Diverse herbivorous fishes coexist on a rocky littoral of the lake. Herbivorous cichlids have acquired multiple feeding ecomorphs, including grazer, browser, scraper, and scooper, and are segregated by dietary niche. Within each ecomorph, however, multiple species apparently coexist sympatrically on a rocky slope. Previous observations of their behavior show that these cichlid species inhabit discrete depths separated by only a few meters. In this paper, using carbon (C) and nitrogen (N) stable isotope ratios as markers, we followed the nutritional uptake of cichlid fishes from periphyton in their feeding territories at various depths. Results: δ15N of fish muscles varied among cichlid ecomorphs; this was significantly lower in grazers than in browsers and scoopers, although δ15N levels in periphyton within territories did not differ among territorial species. This suggests that grazers depend more directly on primary production of periphyton, while others ingest animal matter from higher trophic levels. With respect to δ13C, only plankton eaters exhibited lower values, suggesting that these fishes depend on production of phytoplankton, while the others depend on production of periphyton. Irrespective of cichlid ecomorph, δ13C of periphyton correlated significantly with habitat depth, and decreased as habitat depth became deeper.

  • Testing the Potential of Environmental DNA Methods for Surveying Lake Tanganyika's Highly Diverse Fish Communities Christopher J
    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.

Therefore, understanding contest behaviour can help to elucidate the trade- offs of living in differing social systems and shed light on the evolution of social behaviour. In the current study, we compared contest behaviour in two closely related species of Lamprologine cichlid fish. Neolamprologus pulcher and Telmatochromis temporalis are both pair-breeding cich- lids, but N. pulcher are highly social, group-living fish, while T. temporalis display no grouping behaviour. To examine how competition varies by species, sex and familiarity, we staged same-sex conspecific contests over a shelter, a resource that is highly valued by both species, where contes- tants were either familiar or unfamiliar to one another. When we examined tactical and strategic components of these contests, we found that the highly social species had shorter contests and engaged in fewer costly aggressive acts than did the non-social species. Individuals of the highly social species were also more likely to resolve conflicts through the use of submissive displays, while individuals of the non-social species were more likely to flee from conflict.

  • A Revised Synonymy of Telmatochromis Temporalis (Teleostei, Cichlidae) from Lake Tanganyika (East Africa)
    Journal of Fish Biology (2001) 58, 639–655 doi:10.1006/jfbi.2000.1475, available online at http://www.idealibrary.com on REGULAR PAPERS A revised synonymy of Telmatochromis temporalis (Teleostei, Cichlidae) from Lake Tanganyika (East Africa) M. H* J. S Africa Museum, Vertebrate Section, Ichthyology, Cichlid Research Unit, Leuvensesteenweg, 13, B-3080 Tervuren, Belgium (Received 4 July 2000, Accepted 13 October 2000) The taxonomic status of the nominal species Telmatochromis temporalis, T. lestradei, T. burgeoni and Julidochromis macrolepis has been reviewed. The synonymy of T. lestradei with T. temporalis is confirmed. A comparison of Telmatochromis burgeoni with Telmatochromis temporalis revealed no significant differences either. Hence T. burgeoni is considered synony- mous with T. temporalis. Examination of the type of Julidochromis macrolepis showed it to be conspecific with Telmatochromis dhonti and not with T. temporalis, as had been suggested. 2001 The Fisheries Society of the British Isles Key words: Telmatochromis; Lake Tanganyika; cichlids; synonymy; taxonomy. INTRODUCTION The systematics of the cichlids of the East African Lakes are very complicated and at present taxonomic knowledge is still poor (Fryer & Iles, 1972; Coulter et al., 1986; Greenwood, 1991; Rossiter, 1995; Snoeks, 2000). Even for the relatively well-known Lake Tanganyika, taxa with a supposedly stable taxonomy turn out to be problematic when a revision is made (Verheyen et al., 1996; Hanssens et al., 1999; Ru¨ber et al., 1999). As a result of an ongoing study on the taxonomy and distribution patterns of the lamprologine cichlids from Lake Tanganyika (Snoeks et al., 1994) several problems were encountered within the genus Telmatochromis Boulenger, 1898.

  • Mapping of Quantitative Trait Loci Underlying a Magic Trait in Ongoing Ecological Speciation Tetsumi Takahashi1,2*, Atsushi J
    Takahashi et al. BMC Genomics (2021) 22:615 https://doi.org/10.1186/s12864-021-07908-4 RESEARCH Open Access Mapping of quantitative trait loci underlying a magic trait in ongoing ecological speciation Tetsumi Takahashi1,2*, Atsushi J. Nagano3 and Teiji Sota4 Abstract Background: Telmatochromis temporalis is a cichlid fish endemic to Lake Tanganyika. The normal and dwarf morphs of this fish are a clear example of ongoing ecological speciation, and body size plays an important role in this speciation event as a magic trait. However, the genetic basis underlying this trait has not been studied. Results: Based on double-digested restriction-site associated DNA (ddRAD) sequencing of a hybrid cross between the morphs that includes F0 male, F0 female, and 206 F2 individuals, we obtained a linkage map consisting of 708 ddRAD markers in 22 linkage groups, which corresponded to the previously reported Oreochromis niloticus chromosomes, and identified one significant and five suggestive quantitative trait loci (QTL) for body size. From the body-size distribution pattern, the significant and three of the five suggestive QTL are possibly associated with genes responsible for the difference in body size between the morphs. Conclusions: The QTL analysis presented here suggests that multiple genes, rather than a single gene, control morph-specific body size. The present results provide further insights about the genes underlying the morph specific body size and evolution of the magic trait during ecological speciation. Keywords: Body size, Cichlid fish, Lake Tanganyika, Polygenic inheritance, Telmatochromis temporalis Background [4–6]. This suggests that body size could be a candidate Ecological speciation is the process by which barriers to magic trait.

E-mail: [email protected], [email protected] 2African Diving Ltd, P. O. Box 7095, Dar es Salaam, Tanzania. E-mail: [email protected] Abstract Chalinochromis cyanophleps is described from nine specimens, the largest 129 mm SL, from Namansi. It differs from other species of Chalinochromis in plain trunk colouration, absence of black stripes on the head, relatively narrow lips, presence of tricuspid jaw teeth, and presence of five rather than four dentary lateralis foramina. The blue iridescent stripe below the eye is shared with other lamprologin cichlids, but is broader and more conspicuous in C. cyanophleps. Chal- inochromis cyanophleps occurs at depths between 6 and 45 m in rocky habitats along the Tanzanian coast of Lake Tang- anyika, from Mvuna Island south to Kalala Island, a stretch of about 90 km. Field observations were made of specimens up to 18 cm total length. The COI DNA barcode sequence differs by 1.8% from that of C. popelini. Key words: DNA Barcode, endemism, meristics, morphometry, taxonomy Introduction The endemic Lake Tanganyika cichlid genus Chalinochromis Poll (1974) presently includes two species characterized by steep head profile and thick papillose lips.

Here, we provide a current inventory of the cichlid fish Communicated by Björn Stelbrink fauna of Lake Tanganyika, providing a complete list of all valid 208 Tanganyikan cichlid species, and discuss the taxonomic status of more than 50 undescribed taxa on the basis of the available literature as well as our Keywords: own observations and collections around the lake. This leads us to conclude that there are at least 241 cichlid spe- Biodiversity cies present in Lake Tanganyika, all but two are endemic to the basin. We finally summarize some of the major Ichthyodiversity taxonomic challenges regarding Lake Tanganyika's cichlid fauna.
