Taiwania. down to 10°C) and salinities from fresh to seawater. The background colour of G. brasiliensis is often silvery light brown though significant dissimilarities in body colour and patterning are observed depending on locality. These spots are more noticeable when removed from the water. The diploid/haploid chromosome numbers for G. brasiliensis are 2n/n = 48/24 (Klinkhardt et al., 1995; Arkhipchuk, 1999; Froese and Pauly, 2014). The introduced population of G. brasiliensis in southwestern Australia consumed principally vegetation/detritus. Le Geophagus brasiliensis passe la majeure partie de son temps à filtrer le sable pour y trouver sa nourriture. The highly endemic (82%) freshwater fishes of south-western Australia are imperiled due to severe habitat and water quality declines and impacts of introduced species. We suggest that this relationship results from processes linking growth rate and sexual differentiation to frequency-dependent variation in life-history strategies. 21-34. i have had him no more than one month, when i bought him he was 2" tl, now he is 4.5" tl. There is a long first pelvic ray and three anal spines. G. brasiliensis attained maturity in the second year of life at a LT50 of approximately 91 mm total length (TL) (70 mm SL) for females and ca 82 mm TL (~63 mm SL) for males. Arsenic concentration in Geophagus brasiliensis decreased with increasing fish weight. The greater reproductive investment in river populations was attributed to the environment being more unstable and therefore the species was maximising the chances of a successful spawning event. Fish and Wildlife Service, Gainesville, FL. The Pet Trade as a Source of Invasive Fish in Taiwan. Comparisons were made of their age and size compositions, growth rates, ages and sizes at first maturity, and spawning times. Recommended water hardness (dGH): 5 - 19°N (89.29 - 339.29ppm) 0°C 32°F 30°C 86°F. Loiselle (1980) claimed that captive fish can “briefly tolerate” temperatures as low as 13°C. by Silva S De].

Of particular note is that the species is highly tolerant of temperature and salinity variability and may survive in the low temperatures of temperate latitudes (i.e. Mazzoni R; Iglesias-Rios R, 2002. G. brasiliensis was the first species of Geophagus to enter the aquarium trade and therefore has some economic value. The size at maturity of G. brasiliensis in Brazil differed between populations; i.e. Introductions into the USA are believed to have come from Brazil via the aquarium trade (USGS NAS). The water temperature should be kept at least at 72°, but preferably higher. Description: Aspergillus brasiliensis ( A. brasiliensis) was discovered in 1729 by Pier Antonio Micheli, a priest. Riehl and Baensch (1991) recorded the fecundity of aquarium specimens as 600 to 800. It has been introduced via the aquarium trade into Australia, Florida (the USA), the Philippines and Taiwan. Rantin and Petersen (1985) investigated the temperature tolerance of the species and found its lower lethal temperature limit varied depending on the temperature of acclimatisation and ranged from 8°C (acclimatised at 12.5°C) to 17.8°C (when acclimatised at 32.5°C).

It appeared that recruitment only occurred in lentic habitats; however the species also persists in downstream lotic habitats. Published literature suggests that the maximum size is approximately 250 mm for males and markedly smaller for females. Direct predation of sympatric fish may also occur, particularly as noted previously, G. brasiliensis grows larger than all but one of the local species in south western Australia. (2003). The species has since been collected from three Australian states, Queensland, New South Wales and Western Australia. A new species of the loricariid catfish genus Hemipsilichthys from southern Rio de Janeiro coastal rivers, southeastern Brazil (Teleostei: Siluriformes).
