Tissue total antioxidant capacity(TAC), superoxide dismutase(SOD), catalase(CAT) and maleic dialdehyde(MDA) were chosen as measures of its antioxidant capacity. All fish which received an astaxanthin(from micro-algal H. pluvialis) supplemented diet with 400 mg/kg of astaxanthin, after 50 days of feeding, the astaxanthin-fed fish displayed a pinkcolored skin and the control-fed fish displayed a grayish skin. For the growth, the weight gains of controlfed fish and astaxanthin-fed fish were 200% and 300%, respectively. Samples of skin and scales were used for analysis of total carotenoids and astaxanthin content, and fish feeding astaxanthin showed significantly( P <0.05) higher concentrations than the control group, indicating that the pigmentation of this fish had been significantly improved by dietary astaxanthin. Compared with the control fish, pigmented fish had lower SOD, CAT and MDA and higher TAC. It can be concluded that supplementation with dietary astaxanthin could eff ectively enhance growth, skin coloration and the antioxidant capacity of this fish. This study will provide a reference for application of natural astaxanthin from H. pluvialis as feed additives in blood parrot artificial breeding. Our data is also useful in ornamental fish farming, especially when the retentivity of astaxanthin in the skin and scales are involved. It is leading to the possibility of increasing the pigmentation of farmed-fish by adding the powdered form of H. pluvialis to the diet as an ef fective pigment.展开更多

Test with fluorescein dye was negative. The dense corneal opacity (macula) was identified as involving the posterior corneal layer. The further ophthalmic examination was done and hypermature phacolytic cataract was diagnosed. No other abnormality was detected. Medical management with topical nepafenac prednisolone and triple antibiotic was instituted. The corneal lesion subsided completely within one week followed by spontaneous resorption of the cataract. The treatment protocol was successfully eliminated the discomfort and intraocular lesions in the senile parrot.展开更多

Thus, the study of genetic diversity within and among species or populations is especially important on conservation biology scopes. One way to assess the genetic diversity is through the use of microsatellite molecular markers. Microsatellites have been widely used to answer population genetics issues as gene flow, parentage, and population structure, mostly resulting in data on the distribution of genetic variability within and among natural populations, which are essential for ex situ and in situ conservation procedures. As the Psittacidae family comprehends one of the birds group with the largest number of endangered species, studies that aim to investigate the genetic diversity of these animals may support their conservation. This article is a review of genetic data on parrots, through the use of microsatellite markers, that have been published since 2004.展开更多
