Maidenhead Aquatics Datasheet Lake
Maidenhead Aquatics Datasheet Lake Tanganyika Cichlids Lake Tanganyika is the deepest lake in Africa, and holds a very different assemblage of species to both Lake Malawi and Lake Victoria. There are many sub-groups of fish in this lake, all with different behaviour, environments and overall appearance. Tanganyikan cichlids also need hard, alkaline water with a pH around 8.0. They are usually must less aggressive and do not need to be overcrowded. However, they are not suitable for keeping in a community tank, and should not be mixed with the more boisterous Malawi's and Victorian's. Many species are small, so they can easily be kept in very small tanks, providing the water is kept free of pollution. SHELL DWELLERS Some species, such as many Neolamprologus species breed and take shelter in the shells of large aquatic snails. Many of these fish are fully grown at sizes of around 4cm (1%M), and can be kept alongside other larger species. For their size they are very aggressive and when breeding will often bite hands entering the tank for cleaning purposes. CAVE SPAWNERS Julidochromis, Variabilichromis, Altolamprologus and some Neolamprologus species spawn in crevices between rocks or in caves. Many of these form strong pair bonds, and have protracted parental care. Some species, for example, lay around 300 eggs. The young fry are guarded not only by both parents, but also by the previous generation of fry (older brothers and sisters). MOUTH BROODERS Some species, such as Tropheus and Xenotilapia are mouth brooders. Tropheus lay around 30 eggs which are kept in the female's mouth for around 30 days. -
Eco-Ethology of Shell-Dwelling Cichlids in Lake Tanganyika
ECO-ETHOLOGY OF SHELL-DWELLING CICHLIDS IN LAKE TANGANYIKA THESIS Submitted in Fulfilment of the Requirements for the Degree of MASTER OF SCIENCE of Rhodes University by IAN ROGER BILLS February 1996 'The more we get to know about the two greatest of the African Rift Valley Lakes, Tanganyika and Malawi, the more interesting and exciting they become.' L.C. Beadle (1974). A male Lamprologus ocel/alus displaying at a heterospecific intruder. ACKNOWLEDGMENTS The field work for this study was conducted part time whilst gworking for Chris and Jeane Blignaut, Cape Kachese Fisheries, Zambia. I am indebted to them for allowing me time off from work, fuel, boats, diving staff and equipment and their friendship through out this period. This study could not have been occured without their support. I also thank all the members of Cape Kachese Fisheries who helped with field work, in particular: Lackson Kachali, Hanold Musonda, Evans Chingambo, Luka Musonda, Whichway Mazimba, Rogers Mazimba and Mathew Chama. Chris and Jeane Blignaut provided funds for travel to South Africa and partially supported my work in Grahamstown. The permit for fish collection was granted by the Director of Fisheries, Mr. H.D.Mudenda. Many discussions were held with Mr. Martin Pearce, then the Chief Fisheries Officer at Mpulungu, my thanks to them both. The staff of the JLB Smith Institute and DIFS (Rhodes University) are thanked for help in many fields: Ms. Daksha Naran helped with computing and organisation of many tables and graphs; Mrs. S.E. Radloff (Statistics Department, Rhodes University) and Dr. Horst Kaiser gave advice on statistics; Mrs Nikki Kohly, Mrs Elaine Heemstra and Mr. -

May Atyid Shrimps Act As Potential Vectors of Crayfish Plague?

NeoBiota 51: 65–80. https://doi.org/10.3897/neobiota.51.37718 Abstract The causative agent of crayfish plague, Aphanomyces astaci Schikora, was long considered to be a specialist pathogen whose host range is limited to freshwater crayfish. Recent studies, however, provided evidence that this parasite does not only grow within the tissues of freshwater-inhabiting crabs but can also be successfully transmitted by them to European crayfish species. The potential to act as alternative A. astaci hosts was also indicated for freshwater shrimps. We experimentally tested resistance of two freshwater atyid shrimps: Aty- opsis moluccensis (De Haan, 1849) and Atya gabonensis Giebel, 1875. They were infected with the A. -

Abstract Background: The tribe Lamprologini is the major substrate breeding lineage of Lake Tanganyika's cichlid species flock. Among several different life history strategies found in lamprologines, the adaptation to live and breed in empty gastropod shells is probably the most peculiar. -

Volume 64, Issue 8 November, 2020 London Aquaria Society www.londonaquariasociety.com I Have a Monster in my Aquarium. What is it? www.thenakedscientists.com/forum/index.php?topic=35468.0 A monster's moved itself into my house and I've not even shagged it. I have a small indoor heated aquarium which fits within a picture frame and hangs on the wall of my living room. The tank is about 2.5 foot long by about 18 inches high by about 2 or 3 inches deep and is fully enclosed in a wooden frame. It contains guppies and a lot of weed and snails. A couple of weeks ago I saw what I thought was a spider drowning, thrashing/swimming in the tank. I tried to fish it out but it buried itself in the gravel and I lost it. A few hours later I was amazed to see it sitting in the weed. Upon closer examination I could see it has six legs, clearly has a head, abdomen and thorax, has a laterally flattened body and it’s abdomen was pulsating, presumably to facilitate breathing. It was then about 10mm long but is now about 15. No fish seem to be disappearing and I have a number of baby guppies which are smaller than it is. But I suspect it is eating snails. I assume it is an insect larva and was probably introduced on the weed, possibly as an egg. But since it is a tropical tank I have no idea whether the weed is of native or foreign origin. -

Alloparental care in clownfishes Binu Varghese Marine Products Exports Development Authority, Kochi, India Parental care in clownfishes is well known, mouthing and fanning are the important behaviours apart from defending eggs from predators. They fan the egg mass using pectoral and caudal fins and thus provide necessary water movement to the densely packed clutch and thus help in faster removal of metabolic wastes (Figure 1). Clownfishes also remove unfertilized and unhealthy eggs from the clutch (egg batch). -

The Wednesday Reader December 9, 2020 MCEE Teacher Talks & Topics for December 9 and January 13 As promised when the Montana Council on Economic Education (MCEE) convened their first group of teachers for our online professional development this summer, they wanted to adapt and offer programing that added value and evolved based on feedback. MCEE has received encouragement to continue the monthly check-in opportunities, but to focus on different topics that could be more relevant to different classroom experiences. For December, MCEE invites teachers to join and share the best technology tools in teaching business they have found. This conversation will be led by teachers and will be an honest and candid review on the available tools. There will be an opportunity to share successes or gaps in the tools out there. Business - Wednesday, December 9 from 4 p.m. to 5 p.m. In January, MCEE will bring the focus to our teachers working in Economics and the best tools/methods in delivering economic fundamentals either in person or remotely in today's C19 environment and the uncertainties of attendance. Economics - Wednesday, January 13 from 4 p.m. to 5 p.m. Click the links above to register. If you have topics you want highlighted for February, March or April, please email Dax Schieffer at [email protected]. Jump$tart Announces Free Online Professional Development via J$FFE Online The Jump$tart Coalition for Personal Financial Literacy is excited to announce a new professional development opportunity—Jump$tart Financial Foundations for Educators Online, or J$FFE Online. J$FFE is a comprehensive, content-based professional development program for teachers, designed to improve their own financial knowledge and confidence – and help them make smart consumer decisions of their own – before taking that knowledge into classrooms at all grade levels. -
