Cichlid

Lake Victoria (LV) is the largest tropical lake and has experience a series of changes in dynamics. In the 1970s most of the fisheries were artisanal and was mostly Cichlids, and then LV was converted to a multimillion dollar commercial fishery and was about 90% of the fishing exports in volume and value when the Nile Perch was introduced to LV. This interest the fisheries because the different governments that have jurisdiction of LV incented the move to a more commercial fishing by licensing the fish processing, fishmeal firms, boat registration, fines, trading licensees and exports for economic revenues to each State (Matsuishi 2006). In the 1980s the Nile Perch was introduced to LV and cause a decrease of native species of Haplochromine…

Niger, and Senegal Rivers. The taxonomic status Victoria populations is uncertain. The large fish was introduced to Lake Victoria in the late 1950s and early 1960s from the shallow waters of Lake Albert and Lake Turkana (McDonnel 2015). Although not necessarily conspecific with L. niloticus, the Lake Victoria Lates have always been referred to as L. niloticus (Lowe 2000). Various introductions of the Nile being brought into non-native bodies of water resulted in the fish flourishing (Achieng…

color and are clear. In addition, Albino fish are used. Many albino fish are used in this industry, especially albino platys,because they are white and easy to color. Blood Parrot Cichlids are also very commonly used as tattooed/painted fish. These fish are large and have beautiful natural coloration which makes more space for the tattoo and a better chance of them being bought. Many different types of fish are used in this industry, the most common are albino fish, Indian Glassy fish and Blood…

preventing or minimizing attacks by the predator. Hunting Behaviours: Cichlids Ambush Predation Similar to defensive adaptation by prey fish, predators have developed behavioural adaptation to help them successfully hunt prey. Some of these adaptations are simpler and can be used to counteract defense mechanism like schooling. For example, white perch (Morone americana), which prey on killifish, can overcome the effects schooling (the predator confusing effects) by attacking fish that have…

reproductive role as swapped, the male is responsible for holding the brood in his mouth after spawning. The female produces the eggs which are transferred to the male mouth where fertilization take place. The males then leave and join a school of unpaired males while the eggs incubate. It can take between 8-14 days for the eggs to fully develop and hatch. To complete this role reversal, after spawning, the females are leave to find another male to spawn with. In this species the females are…

reduction in fish numbers due to high demand for two common species of tilapia thus overexploitation of the existing numbers. Therefore to increase the supply of fish, Nile perch was introduced to Lake Victoria in 1954 by the British colonialists and by 1970s there had been an increase in the fishing output from the lake, firstly observed in Nyanza , Kenya although this was at an expense ("Lake Victoria Fisheries: An Introduction", 2017). Nile perch turned out to be an invasive species by…

Brood parasitism – *There is one fish analogy to the true brood parasitism found in birds. *In Lake Tanganyika, the catfish Synodontis multipunctatus attends the spawning ritual of various mouthbrooding cichlids and lays eggs at the same time, in the same spot. *The female cichlid, as is her normal habit, picks up all the eggs present and commences incubating them inside her mouth. Unable knowns to her, some of those eggs are of catfish. …

During my class’s group review sessions (which I had never seen in any of my other English classes), I noticed that it was hard to keep my classmate’s attention throughout my essay. Looking back, my early essays sounded rather monotonous. For example, in an 8th grade compare and contrast essay, I wrote “When it comes to color, fresh water fish like livebearers, some tetras, most barbs, gourami, killifish, danios and some peaceful cichlids add color to freshwater tanks. Many fish will also…

Thousands of helpless native species have been brought to a tragic ruin throughout history due to countless invasive species that are often intentionally brought into new environments in order to bring about better change, yet they only ever seem to cause everything to get worse. This is why the federal government should develop effective biosecurity measures by increasing international and national funding because it will save thousands of defenseless native species from becoming extinct, and…
