Early-life-stage toxicity in offspring from exposed parent medaka, Oryzias latipes, to mixtures of tributyltin and polychlorinated biphenyls.
The present study examined the effects of tributyltin (TBT), polychlorinated biphenyls (PCBs), and mixtures of both chemicals on reproduction in Japanese medaka, Oryzias latipes. For 21 d we gave groups of medaka freeze-dried brine shrimp flakes contaminated with a mixture of either 0, 1, 5, or 25 microg TBT g(-1) plus 0 or 25 .micro PCBs g(-1). We measured the fecundity and fertility of the pa...
متن کاملLife-cycle toxicity of 4-nonylphenol to medaka (Oryzias latipes).
We studied the chronic effects of 4-nonylphenol (4-NP) on reproductive status of medaka (Oryzias latipes) over two generations of continuous exposure. The exposure study of the parental (F0) medaka was begun on embryos within 24 h postfertilization and continued with monitoring through embryological development, hatching, posthatch survival, growth, sexual differentiation, and reproduction unde...
متن کاملReproductive Success and Behavior of Japanese Medaka (oryzias Latipes) Exposed to 4-tert-octylphenol
Japanese medaka (Oryzias latipes), a small freshwater fish used extensively to investigate sexual differentiation and development, were exposed to octylphenol (OP), a known estrogen agonist, to assess its impact on reproductive success. Male and female medaka were exposed to nominal concentrations of 10, 25, 50, and 100 mg/L OP from 1 d posthatch to 6 months posthatch. In reproduction trials in...
متن کاملGrowth inhibition in Japanese medaka (Oryzias latipes) fish exposed to tetrachloroethylene.
A recent study in our laboratory has demonstrated that tetrachloroethylene (TCE) is acutely toxic to Japanese medaka (Oryzias latipes) larvae with a 96 hr-LC50 of 18 (17-19) mg/mL (Spencer et al., 2002). In the present study we hypothesize that TCE exposure induces a developmental effect in Japanese medaka. Growth and age specific sensitivity of Japanese medaka larvae were studied with four age...
متن کاملFeminization of female leukophore-free strain of Japanese medaka (Oryzias latipes) exposed to 17beta-estradiol.
The recently developed female leukophore-free (FLFII) strain of Japanese medaka (Oryzias latipes) carries DNA markers for the identification of genotypic sex. Information regarding genotypic sex is useful for tests in which endocrine-disrupting compounds may masculinize or feminize fish. In the present study, methods were developed to automate DNA extraction and profiling for rapid determinatio...
