“…biminiensis has a short life cycle, fast development, high reproductive potential and one of the highest rates of increase among harpacticoids in cultures (ARAÚJO-CASTRO; SOUZA-SANTOS, 2005;PINTO et al, 2001;SOUZA-SANTOS et al, 2006). This species has been cultured under laboratory conditions since 1998 and has demonstrated its ability to reach high densities, thereby facilitating its use in toxicity tests.…”

“…Tisbe biminiensis developed better when fed with diatoms than with flagellates (PINTO et al, 2001). Thus, two diatom species (Thalassiosira fluviatilis and Phaeodactylum tricornutum) were used in the present study.…”

“…The age of the first brood of T. biminiensis ranged from 7.6 to 10.8 days and total lifespan of T. biminiensis females ranged from 29 to 32.9 days (PINTO et al, 2001). To minimize natural mortality, 12 day-old ovigerous females were used in the tests.…”

“…Harpacticoid copepods of the genus Tisbe are particularly useful as bioassay organisms due to their high abundance in sediments, wide geographic distribution, short life cycles and amenability to laboratory cultures and handling (POUNDS et al, 2002). Tisbe battagliai is an internationally recognized test species for assessing water and sediment quality and, more importantly, is suitable for toxicity identification evaluation (TIE) (THOMAS et al, 2003).…”

“…It has a short generation time and high reproductive potential (PINTO et al, 2001;SOUZA-SANTOS et al, 2006). It is easily cultured under laboratory conditions; requires low sample volumes; does not need a large amount of space for cultivation; and has an easily observable lethal endpoint.…”

A B S T R A C TFor the future use of the marine benthic copepod Tisbe biminiensis in solid-phase sediment toxicological bioassays, the present study investigated the effect of muddy sediment from the Maracaípe estuary (northeastern Brazil), sediment particle size and the reference toxicant potassium dichromate on the species. Muddy sediment from Maracaípe can be used as control sediment, since it does not interfere in the copepod life-cycle and has metal contamination levels that are unlikely to produce any detrimental biological effects on benthic invertebrates. Neither survival nor fecundity was affected by grain size, suggesting that this species can be used with any kind of sediment from muddy to sandy. The sensitivity of T. biminiensis to K 2 Cr 2 O 7 in acute tests was similar to that of other organisms. The LC 50 (lethal concentration to 50% of the test organisms) medium values for T. biminiensis were 7.51, 4.68 and 3.19 mg L -1 for Cr in 48, 72 and 96 h, respectively. These results suggest that T. biminiensis is a promising organism for use in solid-phase sediment toxicity assessments. R E S U M OVisando o uso futuro do copépodo marinho bentônico Tisbe biminiensis em bioensaios toxicológicos de sedimentos na fase sólida, o presente estudo investigou o efeito do sedimento lamoso do estuário de Maracaípe (Nordeste do Brasil). Foram considerados a granolometria e o tóxico de referência dicromato de potássio sobre a espécie. O sedimento lamoso de Maracaípe pode ser usado como controle, uma vez que não interfere no ciclo de vida do copépodo e possui níveis de contaminação de metais que não causariam efeitos biológicos em invertebrados bentônicos. Nem a sobrevivência ou fecundidade foi afetada pelo tamanho do grão, sugerindo que esta espécie pode ser usada com qualquer tipo de sedimento, de lama a areia. A sensibilidade de T. biminiensis ao K 2 Cr 2 O 7 em testes agudos foi similar a de outros organismos. Os valores de CL 50 (concentração letal a 50% dos organismos) para T. biminiensis foram em média 7,51, 4,68 e 3,19 mg L -1 para o Cr em 48, 72 e 96h, respectivamente. Estes resultados sugerem que T. biminiensis é um organismo promissor para uso em avaliações de toxicidade com a fase sólida do sedimento.
