The colors presented in ornamental fish determine their acceptability in the market, which is one of the main factors which determine their price. Selecting the fish by only looking at them makes the result analysis based in statistics difficult. Thus, it has become necessary to develop a method of quantification for practical use, which will apply minimal stress to the fish while being economically feasible. The proposed method uses a technique which converts the colors of interest to numerical indexes usable in statistical methods of higher precision. The results increase the abilities of fish nutrition researchers aiming to intensify the color characteristics of fish through selective breeding and genetic engineering with the intent of reliably achieving the desired visual characteristics for commercialization.

Automated image systems to characterize aquatic organisms improve research and enable fast response to environmental risk situations. In November 2015, a dam in Mariana City-MG (Brazil) collapsed and led to the disposal of mud tailings from the mining process to the Doce River. The accident resulted in several casualties and incalculable damage to surrounding communities and the environment. The mud increased water turbidity, an essential condition to the functioning of the image analysis systems, and directly affected the characterization of the organisms, making it impossible to distinguish copepods in the mud, due to the blurred outline. To get a quick response evaluating environmental situations, this work aimed to develop and test different algorithms characterizing and classifying copepods by their size (length and area) using in situ images acquired by the Lightframe On-Sight Keyspecies Investigation device. Field tests were carried out under different turbidity levels throughout the gradient observed in the coastal zone adjacent to the Doce River. The best algorithm reduced nearly 50% of the noise in some images when compared with manual treatment and led to 96% accuracy in measurement and counting. Semi-automated devices that perform post-processing corrections are suitable for fast environmental evaluation under high turbidity scenarios.

The use of medicinal plants as therapeutic and economic resources has been on the rise in recent years. In Brazil, however, increasing doubt is being cast on the quality of these products, owing to the prevalence of adulteration and fraud. Solar radiation can cause serious damage to human skin, as a result, mostly, of ultraviolet light, which is a cause of skin cancer. Photoprotective substances are capable of absorbing, reflecting, or refracting ultraviolet radiation and thus protecting skin from exposure to sunlight. The present study aimed to characterize samples and examine the phytochemical profile and photoprotective potential of bark and leaves of Erythrina velutina Willd. The samples underwent five extraction methods using 80% ethanol. The phenolic content was measured using spectrophotometry. Antioxidant activity was examined using the DPPH and the photoprotective properties of the plant extracts were assessed using the method developed by Mansur. There was a quantitative difference in some groups of metabolites, with higher levels of tannin in the bark and of flavonoids in the leaves. The latter showed greater DPPH free radical scavenging capacity than the bark, although higher levels of SPF were obtained from the bark, with no statistically significant differences between methods. The results indicate that Erythrina velutina Willd. has potential as a photoprotector.
