چکیده
O lambari, Astyanax bimaculatus, é uma das espécies nativas com potencial zootécnico para a aquicultura, e se destaca características desejáveis o cultivo, logo, estudos referentes à quantidade ideal de alimento são necessários melhorar desempenho da espécie. Sendo assim, objetivou-se avaliar descrever influência frequência alimentar sobre crescimento do A. bimaculatus. Matrizes A.bimaculatus foram capturadas em piscicultura maranhense, hipofisadas laboratório hormonôno sintético seguida casais estocados sistema desova semi-induzida. Após eclosão as pós-larvas transferidas um tanque berçário, treinamento ração comercial durante 20 dias. Posteriormente os alevinos submetidos biometria transferidos unidades experimentais tratamentos pré-estabelecidos, três diferentes frequências alimentares, sendo duas, quatros vezes ao dia, até saciedade aparente, monitoramento água foi realizado semanalmente. Os resultados demonstraram que alimentação natural juntamente 45%PB influenciaram signficamente. parâmetros físico-químicos mantiveram-se dentro dos padrões aceitáveis espécie toda pesquisa, índices zootécnicos apresentaram linear. Concluiu-se bimaculatus influenciado pela alimentar. Considerando ganho peso, indica-se podem atingir melhor quando alimentados quatro dia. Ressaltando favorecimento na conversão proveniente aumento

Toxicity and genotoxicity in Astyanax bimaculatus (Characidae) induced by microcystins from a bloom of Microcystis spp
Studies of genotoxicity in fish caused by cyanobacterial microcystins can be useful both in determining the sensitivity of native species, as well as comparing exposure routes. The genotoxicity caused by the microcystins LR and LA from a bloom collected in a eutrophic lake, was revealed in the fish Astyanaxbimaculatus, a native species from South America. LC50 (72 h) was determined as 242.81 μg...

Astyanax douradilho, new species, is described from the rio Tramandaí system, coastal drainage of Rio Grande do Sul State, Brazil. The new species is distinguished from its congeners by possessing 37-39 perforated scales along the lateral line, 3-5 maxillary tricuspid teeth, 22-24 branched anal-fin rays, absence of a conspicuous dark stripe from humeral region to caudal peduncle, two vertically...
متن کاملReproductive traits and population structure of Astyanax aeneus (Characiformes: Characidae) from a subtropical river in Mexico.
Champotón River is an unknown area within the Mesoamerican hotspot in Southestern México. Reproductive traits and population structure of Astyanax aeneus were analyzed along an environmental gradient of the upper, middle and lower sections of the river, where diverse environmental factors were recorded. For this, nets were cast for 1 h at each site and A. aeneus were collected from all sections...
متن کاملComparative cytogenetics among populations of Astyanax altiparanae (Characiformes, Characidae, Incertae sedis)
Cytogenetic data are presented for Astyanax altiparanae populations from three Brazilian hydrographic systems. The chromosomal data obtained in A. altiparanae support the hypothesis of diploid number conservation. However, small differences in the karyotype formula and number of nucleolar organizer regions were observed in these populations. The apparent karyotypical similarity among the studie...
