“…The native distribution of Nile tilapia covers most of central Africa, limited to the north by the Sahara Desert and to the south in northern South Africa, where the limiting factor might be low air and water temperatures (Sifa et al 2002). Our models predicted potential distributional areas across most of Africa except for the Sahara and the Kalahari deserts, but including the Mediterranean coast (Fig.…”

Nonnative fish introductions disrupt ecosystem processes and can drive native species to local extinction. Two of the most widespread, introduced species are the common carp (Cyprinus carpio) from Eurasia and the Nile tilapia (Oreochromis niloticus) from Africa. In North and South America, these introductions stem from aquaculture facilities, as well as historical introductions for recreational angling. An emergent field of ecological niche modeling provides robust predictions of the geographic potential of alien species to better understand their capacity to become established at broad scales. We used this modeling approach to produce spatially explicit predictions of the invasive potential of common carp and Nile tilapia in the Americas. Model predictions were tested using occurrence data for established populations in their native area and in the Americas. Results indicated that predictive power of niche models was high. Distributional potential of common carp in the Americas covers most temperate regions and high mountain tropical aquatic systems, whereas that of Nile tilapia is focused in the tropics and coast areas. The consequences of the potential establishment of these exotic species can be profound on native aquatic faunas, particularly on highly diverse regions such as the Amazon Basin and central Mexico.

“…Unsuitable water quality elements such as water temperature (Sifa et al 2002;Cagauan 2001;Black 1998;Alcaraz et al 1993;Chervinski 1982), water oxygen (Black 1998;Ross 2000) and water pH (Svobodova et al 1993) levels were shown to have a negative effect on fish growth. Especially within extensive and semi-intensive aquaculture systems, fish growth is correlated with the availability and abundance of natural food resources (Rahman et al 2008b;Muendo et al 2006;Schroeder et al 1990;Spataru et al 1983;Kolar and Rahel 1993;Pucher et al 2011b), and both water quality and the availability of natural food are primarily or secondarily affected by the suspended particle load.…”

“…It can be observed less weight of fish cultured at 22ºC and low survival rate. Sifa, Chenhong, Dey, Gagalac and Dunham (2002) observed that two wild strains of tilapia, found in China, had better cold tolerance than the GIFT strain, and the authors attributed this to the following factors: the recent introduction of the GIFT strain in China did not allow the selection of this strain to low temperatures, African strains introduced in China for several years, were exposed to low water temperatures and thus allowed a kind of natural selection. Another possibility for this low cold tolerance may be due to possible contamination with Oreochromis mossambicus (which has low cold tolerance) while selecting the GIFT strain.…”

ABSTRACT. This study aimed to evaluate the effect of temperature on the tissue growth of Red, GIFT and Supreme tilapia strains. Fingerlings of approximately 1.4 g from male populations were reared for a period of 60 days, in three recirculating systems, each system containing 6 water tanks of 0.5 m³, at three temperatures (22, 28 and 30ºC). Ten fish of each recirculation system and each temperature studied were sampled. Fishes have been anesthetized, euthanized and weighed. The samplings have been done from the dorsal musculature, caudal, visceral and ventral subcutaneous adipose tissue. Histological sections were prepared and evaluated to determine the diameter of the cells. The experimental design was completely randomized factorial 3 X 3 (strain X temperature). Analysis of variance was performed and means were compared. Higher weights were found for fish reared at 30°C (56.23 g) compared to those grown at 28 (42.12 g) or 22°C (10.52 g). The cooled water temperature (22°C) may have contributed to the hypertrophy of white muscle fibers and visceral adipocytes from tilapia, compared to 28 or 30ºC. Red Tilapia, GIFT and Supreme strains show differences in muscle growth and adipose tissues in response to temperature of cultivation.Keywords: adipocytes, white fibers, red fibers, GIFT strain, red strain, supreme strain.Influência da temperatura de cultivo no crescimento muscular e do tecido adiposo em linhagens de tilápia do Nilo (Oreochromis niloticus) RESUMO. Objetivou-se avaliar o efeito da temperatura no crescimento dos tecidos de tilápias do Nilo das linhagens Vermelha, GIFT e Supreme. Alevinos de aproximadamente 1,4 g, oriundos de populações de machos revertidos, foram mantidos em três sistemas de recirculação. Cada sistema contendo contém seis caixas d'água de 0,5 m³, em três temperaturas (22, 28 e 30ºC). Foram coletados dez peixes de cada tratamento. Os peixes foram insensibilizados, eutanasiados e pesados. Foram realizadas amostragens das regiões da musculatura dorsal, do pedúnculo caudal, do tecido adiposo subcutâneo ventral e visceral. Lâminas histológicas foram confeccionadas e avaliadas para determinar o diâmetro das células. O delineamento experimental foi inteiramente casualizado em esquema fatorial 3 X 3 (linhagem X temperatura). A análise de variância foi realizada e as médias foram comparadas. Maiores pesos foram encontrados para os peixes cultivados a 30ºC (56,23 g), quando comparados àqueles cultivados a 28 (42,12 g) ou 22ºC (10,52 g). A temperatura resfriada da água (22ºC) pode ter contribuído para a hipertrofia das fibras musculares brancas e dos adipócitos viscerais das tilápias, quando comparada a 28 ou 30ºC. As linhagens de tilápia Vermelha, GIFT e Supreme apresentam diferenças de crescimento do tecido muscular e adiposo em resposta à temperatura de cultivo.Palavras-chave: adipócitos, fibras brancas, fibras vermelhas, linhagem GIFT, linhagem vermelha, linhagem supreme.
