Young Oocytes of the Loach, Noemacheilus barbatulus (L.) (Teleostei, Cobitidae) Young oocytes of the loach, Noemacheilus barbatulus (L.), were studied by electron microscopy. Fistular paracristalline bodies are found in the oocytes during state I. They consist of many osmiophilic particles with a diameter of 150 - 300 Å. Ultrahistochemical experiments have demonstrated that the paracristalline bodies are mainly composed of pro­ teins. The paracristalline bodies are yolk precursors.
