The parasites were collected, processed and identified according to specific procedure. Literature review was carried out to compile records of occurrence of gill parasites species in other Brazilian river basins. Results: A total of seven (7) species of parasites were recorded, five (5) of the genusCichlidogyrus , one (1) of Scutogyrus (Ancyrocephalidae, Monogenoidea) and one (1) of Lamproglena, Lamproglena monodi (Copepoda, Lernaeidae). All native from Africa. Some of these species have been reported in fish farms located in five other Brazilian watersheds. -

Mozambique Tilapia)
UWI The Online Guide to the Animals of Trinidad and Tobago Behaviour Oreochromis mossambicus (Mozambique Tilapia) Family: Cichlidae (Cichlids and Tilapias) Order: Perciformes (Perch and Cichlids) Class: Actinopterygii (Ray-finned Fish) Fig. 1. Mozambique tilapia, Oreochromis mossambicus. [http://ja.wikipedia.org/wiki/%E3%83%95%E3%82%A1%E3%82%A4%E3%83%AB:Oreochromis_mossambicus_ by_NPS.jpg, downloaded 5 October 2012] TRAITS. Oreochromis mossambicus is a medium sized, laterally compressed fish that has long dorsal fins with 10-13 rays and spines (Froese & Pauly 2007). Its scales are large along the snout and fore head and become smaller along the body (Luna 2012). The coloration is a dull greenish yellow with weak banding pattern along the body (Froese & Pauly 2007). The adults range in size from 25 cm in the female to approximately 35 cm in the male. The male has an average weight of 2.5 pounds and the female ranges from 1.8-2 pounds at its maximum weight (Froese & Pauly 2007). O. mossambicus exhibits sexual dimorphism, the best descriptors are the premaxilla width, anal fin height and snout length; traits vital for agonistic displays, nesting and fighting (Oliveira & Almeda 1995). The size and coloration vary in captivity and with its diet. Some O. mossambicus look almost black in colour; females, non-breeding males and fry/ juveniles have a silvery colour on the scales (Luna 2012). O. mossambicus can live in both brackish and salt water and can survive a wide range of temperatures (Froese & Pauly 2007), and can live up to 11 years (Luna 2012).

The Florida Fish and Wildlife Conservation Commission has listed the tilapia Alcolapia grahami as a prohibited species. Prohibited nonnative species (FFWCC 2018), “are considered to be dangerous to the ecology and/or the health and welfare of the people of Florida. These species are not allowed to be personally possessed or used for commercial activities.” Means of Introductions in the United States No records of Alcolapia grahami in the United States were found. 1 Remarks From Bayona and Akinyi (2006): “Vulnerable D2 ver 3.1” Various sources use Alcolapia grahami (Eschmeyer et al. 2017) or Oreochromis grahami (ITIS 2017) as the accepted name for this species. Information searches were conducted under both names to ensure completeness of the data gathered. 2 Biology and Ecology Taxonomic Hierarchy and Taxonomic Standing According to Eschmeyer et al. (2017), Alcolapia grahami (Boulenger 1912) is the current valid name for this species.

This alkaline soda lake in the Rift Valley in Kenya is an extreme environment with pH as high as 11, temperatures up to 42 °C, and diurnal fluctuation between hyperoxia and virtual anoxia. Nevertheless, gyrodactylid monogeneans able to survive these hostile conditions were detected from the gills the Magadi tilapia. The worms were studied using light microscopy, isolated sclerites observed using scanning electron microscopy, and molecular techniques used to genetically characterize the specimens. The gyrodactylid was described as Gyrodactylus magadiensis n. sp. and could be distinguished from other Gyrodactylus species infecting African cichlid fish based on the comparatively long and narrow hamuli, a ventral bar with small rounded anterolateral processes and a tongue-shaped posterior membrane, and marginal hooks with slender sickles which are angled forward, a trapezoid to square toe, rounded heel, a long bridge prior to reaching marginal sickle shaft, and a long lateral edge of the toe. -

The Effects of Introduced Tilapias on Native Biodiversity

DOI: 10.1002/aqc.699 The effects of introduced tilapias on native biodiversity GABRIELLE C. CANONICOa,*, ANGELA ARTHINGTONb, JEFFREY K. MCCRARYc,d and MICHELE L. THIEMEe a Sustainable Development and Conservation Biology Program, University of Maryland, College Park, Maryland, USA b Centre for Riverine Landscapes, Faculty of Environmental Sciences, Griffith University, Australia c University of Central America, Managua, Nicaragua d Conservation Management Institute, College of Natural Resources, Virginia Tech, Blacksburg, Virginia, USA e Conservation Science Program, World Wildlife Fund, Washington, DC, USA ABSTRACT 1. The common name ‘tilapia’ refers to a group of tropical freshwater fish in the family Cichlidae (Oreochromis, Tilapia, and Sarotherodon spp.) that are indigenous to Africa and the southwestern Middle East. Since the 1930s, tilapias have been intentionally dispersed worldwide for the biological control of aquatic weeds and insects, as baitfish for certain capture fisheries, for aquaria, and as a food fish. They have most recently been promoted as an important source of protein that could provide food security for developing countries without the environmental problems associated with terrestrial agriculture. In addition, market demand for tilapia in developed countries such as the United States is growing rapidly. 2. Tilapias are well-suited to aquaculture because they are highly prolific and tolerant to a range of environmental conditions. They have come to be known as the ‘aquatic chicken’ because of their potential as an affordable, high-yield source of protein that can be easily raised in a range of environments } from subsistence or ‘backyard’ units to intensive fish hatcheries. -
