A preliminary study was carried out on electropherograms of eye-lens, muscle proteins and zymograms of muscle esterases of ten Notothenia larseni, six Notothenia nudifrons and one lanternfish, Electrona antarctica. The fish were collected by the R/V "Prof. W. Besnard" of the Institute of Oceanography, University of São Paulo, during the First Brazilian Expedition to Antarctica. Eye-lens proteins were analysed on cellulose acetate membrane, muscle proteins and esterases on gel of polyaorylamide. Eye-lens proteins showed three types of electropherograms for N. larseni, and two types for N. nudifrons. One of the electropherograms of N. larseni can be readily distinguished from those of N. nudifrons. Electropherograms of muscle proteins of N. larseni and N. nudifrons are very similar and, consist of sixteen to seventeen fractions. Electropherograms of muscle proteins of N. larseni are severely affected by the conservation of the extracts overnight under -20ºC. All N. nudifrons were of the same zymograms of esterases while those of N. larseni varied. Electropherograms of eye-lens and muscle proteins as well as zymograms of esterases of the lanternfish are different from those of nototheniids. Foi realizado um estudo preliminar sobre eletroferogramas de proteínas de cristalino e de músculo esquelético, e zimogramas de esterases de músculo esquelético de dez Notothenia larseni, seis Notothenia nudifrons e de um peixe-lanterna, Electrona antarctica. Os peixes foram coletados pelo N/Oc. "Prof. W. Besnard" do Instituto Oceanográfico da Universidade de São Paulo durante a I Expedição Brasileira à Antártica. As proteinas do cristalino foram analisadas em membranas de acetato de celulose, enquanto que as proteínas e esterases do músculo esquelético, em gel de poliacrilamida. As proteínas do cristalino apresentam três tipos distintos de eletroferogramas para N. larseni, e dois para N. nudifrons. Um dos eletroferogramas de N. larseni, pode ser prontamente distinguido dos de N. nudifrons. Eletrof erogramas de proteínas de músculo de N. larseni e de N. nudifrons são muito semelhantes e consistem de 16 a 17 frações. Os eletroferogramas de proteínas de músculo de N. larseni são severamente afetados pela preservação dos extratos por uma noite a -20ºC. Todos os N. nudifrons apresentam um mesmo zimograma de esterases enquanto que os de N. larseni variam. Tanto os eletroferogramas de proteínas do cristalino e do músculo como os zimogramas de esterases do peixe-lanterna são diferentes dos apresentados pelos nototeniideos
