Construção de uma coleção didática ictiológica no laboratório de biologia do Centro de Estudos Superiores de Parintins

Abstract

Collections play an important role in the construction of knowledge regarding the teaching of biological sciences. This work aimed to obtain an ichthyological collection of didactic nature from the Center for Superior Studies of Parintins-CESP. Fish were obtained from two localities: Corredeira do Murituba (Gleba Vila Amazônia, firm hearth stream) and Vila Nova Community (right bank of the Amazon River, floodplain lake). The samples were immersed in 10% formalin for 24 hours and kept in plastic containers with 70% alcohol. The specimens were identified according to identification keys considering the information of the scientific name, common name, date and place of capture. In total, twenty-eight species were identified, six from the order Siluriformes, five from the order Perciformes, one from the order Osteoglossiformes, fourteen from the order Characiformes, one from the order Pleuronectiformes and one from the order Gymnotiformes. All were classified according to the characteristics found in the identification keys described in the literature. It is noticeable in Universities the lack of teaching resources such as ichthyological collections, as well as personnel with basic knowledge for making and using these collections. Thus, the assembly of an ichthyological collection will provide public schools with a point of reference in assisting practical activities in both natural and biological sciences.
