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. -

Imaobong Emmanuel Ekpo Department of Fisheries and Aquatic Environmental Management, University of Uyo, P. M. B. 1017, UYO – 520001, Akwa Ibom State – Nigeria. Corresponding address: [email protected] ; +234-8026073996. Abstract Fish species were investigated for 12 calendar months from March 2009 – February 2010 forthnightly using traps, gillnets and cast nets from three sampling stations in Ikpa River. Ornamental fish species were sorted out from the pooled samples. The findings revealed that of the 2307 fish specimens sampled, 1074 specimens made up of 38 species and 19 families were of indigenous ornamental fish. The highest contributing family in terms of number of species is Cichlidae (10 species) whereas Schilbeidae (593 specimens; 55.21%) is the highest contributor in terms of total number of specimens sampled. This is followed by Mochokidae and Mormyridae with 4 species each and Cichlidae with 158 specimens (14.70%). At the species level, the highest contributor is Physalia pellucida (577 specimens; 53.72%) and is followed by Erpetoichthys calabaricus (60 specimens; 5.59%). The least contributors were Heterobranchus bidorsalis, Periophthalmus barbarus and Pelvicachromis pulcher (1 specimen; 0.09%). Twelve families recorded only one species each. These great potentials of ornamental fish have been left unexploited and hence, undeveloped. -

The African Butterfly Peacock Aulonocara Jacobfreibergi “Eureka Red” by John Moyles
The African Butterfly Peacock Aulonocara jacobfreibergi “Eureka Red” By John Moyles Aulonocara jacobfreibergi (Johnson, 1974) is also called the African butterfly peacock and the fairy peacock. They are endemic to Malawi and are found throughout the lake of the same name. There are several geographical variants of the Aulonocara species in the hobby, including Eureka, Mamela, Otter Point, Hongi Island, Cape Kaiser, Lemon Jake, among others. These should never be housed together as they will readily cross-breed. Only one geographical race should be kept in the same aquarium. Description Males of this species differ from most other Peacocks in their broad, wide white dorsal and caudal fin margins. Females are easily confused with other peacock females, because they are grayish-brown in color with vertical banding on the body and have rounded anal and dorsal fins. Butterfly peacocks are further distinguished from other Peacocks by their large size. They can grow to lengths of up to 8 or 9 inches, but often can breed at half that size. Another distinguishing characteristic of the Butterfly Peacock is its moderate to deeply forked tail fin, which gives it the appearance of a swallow's tail. The “Eureka” variant is an aquarium strain that was developed by line breeding specimens from Otter Point, Malawi. The males have blue throughout head, body and fins. Lower half of the head is blue and the upper part of the dorsal region is orange/red. Anal fin may show red. Dorsal fin has the trademark white/light blue blaze. Diet Butterfly peacocks are specialized feeders. In the wild they mostly consume zooplankton (insect larvae and crustaceans) in the wild. -

Tyers, [email protected] 9 10 Abstract 11 Balancing selection is important for the maintenance of polymorphism as it can prevent either fixation of one 12 morph through directional selection or genetic drift, or speciation by disruptive selection. Polychromatism can 13 be maintained if the fitness of alternative morphs depends on the relative frequency in a population. In 14 aggressive species, negative frequency-dependent antagonism can prevent an increase in the frequency of rare 15 morphs as they would only benefit from increased fitness while they are rare. Heterospecific aggression is 16 common in nature and has the potential to contribute to rare morph advantage. Here we carry out field 17 observations and laboratory aggression experiments with mbuna cichlids from Lake Malawi, to investigate the 18 role of con- and heterospecific aggression in the maintenance of polychromatism and identify benefits to rare 19 mores which are likely to result from reduced aggression.
