Growth 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 کاملEffects of Salbutamol on growth performance and carcass characteristics of Japanese quail (Coturnix japonica)
The effects of feeding diets containing Salbutamol (0, 1, 3, 5 and 7 mg/kg diet) from 21 to 49 days of ageon growth performance and carcass characteristics in 180 male and 180 female Japanese quails (Coturnixjaponica) were studied using a factorial arrangement based on completely randomized design. Gender hadsignificant effect on weight gain (Pwere not statistically significant (P>0.05). Salbut...
متن کاملScrutinizing of a Liquid Prebiotic on Growth Performance and Internal Organs of Japanese Quail
An experiment has been conducted to evaluate the effects of a liquid prebiotic (LP) on the carcass, digestive tract, and productive traits of Japanese quail. Eighty 7-day-old Japanese quails were randomly divided into 2 treatments. Each treatment consisted of 4 replicates (pens) of 10 birds each. The first treatment (control) contained a standard recommended diet with no added prebiotic. The se...
متن کاملChronic toxicity of chloroform to Japanese medaka fish.
Japanese medaka (Oryzias latipes) were continually exposed in a flow-through diluter system for 9 months to measured chloroform concentrations of 0.017, 0.151, or 1.463 mg/L. Parameters evaluated were hepatocarcinogenicity, hepatocellular proliferation, hematology, and intrahepatic chloroform concentration. Histopathology was evaluated at 6 and 9 months. Chloroform was not hepatocarcinogenic to...
متن کاملGrowth gradients in fish larvae*
Relative growth intensity of various longitudinally measured body segments in larvae of several species of fishes was distributed across the body in a continuous, U-shaped gradient. Juveniles lacked a simple pattern ofgrowth but appeared to grow nearly isometrically. Body depth exhibited a shallow, U-shaped gradient while body width lacked a discernible pattern. Most intense growth, in three or...
