A review on the use of hormones in fish farming: analytical methods to determine their residues. Repositório Alice
HOGA, C. A.; ALMEIDA, F. L.; REYES, F. G. R..
Hormones are used in fish farming to increase fish production when one sex of a species has the capacity to grow bigger and faster than the other sex. The technique to increase fish production based on sexual dimorphism mostly uses estrogens and androgens. These chemicals must be handled carefully to ensure environmental, biological and food safety, since they can contaminate the environment and promote changes in the endocrine system inducing adverse effects on the consumer health. Another important issue is the reliability of the analytical methods used to identify and/or quantify hormone residues in the meat of treated fish. Therefore, the aim of this review is to bring into view the use of hormones in fish farming, the possible impacts of this practice...

SEX-DETERMINATION SYSTEMS AND THEIR EVOLUTION: MAMMALS Acta biol.Colomb.
COLORADO GARZÓN,FREDY A; MATTA CAMACHO,NUBIA E; SÁNCHEZ,ANTONIO.
Sex-determination methods are very diverse as they have become an enduring research field. Understanding the causes of gonadal development and elucidating the main factors involved in sex-determination of offspring required relating information from far-ranging areas such as cytology, embryology, morphology, molecular biology and even ecology and evolution. This article presents an overview of sex-determination in placental mammals, encompassing several levels of biological organization. The importance of the underlying molecular tools in the context of sex-determination assays and their implications in conservation genetics is also discussed.
