Lebistes Reticulatus

A method based on static bioassays was developed to measure the concentration of toxaphene before restocking of lakes treated with this toxicant. A double distillation technique was used to extract the toxaphene and concentrate it in a small volume of distillate. Bioassays were then carried out in 200-ml samples of distillate reconstituted with electrolytes to match a standard water. Guppies, Lebistes reticulatus (Peters), less than 7 days old were used as test organisms.The method developed was used to follow the detoxification of Midway Lake which was rehabilitated with toxaphene. Data on the rate of detoxification are presented.

Lebistes Reticulatus

Hereditary changes in the shape of the vertebral column in Lebistes reticulatus appeared after ancestral irradiation of immature germ cells with 500 or 1000 R of X-rays. Although the mutant to wild-type ratios in the F2 generation after outcrossing fitted a digenic and a trigenic segregation ratio, respectively, the quantitative characters in question are assumed to be caused by recessive mutations of polygenes which are highly mutable.
