Eggs of the Eurasian perch, Perca fluviatilis, are strongly attached to each other to form 0.5-5.5m long and 1-6 cm wide floating jelly strands or ribbons. The processes involved in the initiation of egg attachment were investigated in the present study. Eggs are released together with small amounts of ovarian fluid. When the eggs come in contact with water, a fibrous jelly-like structure is formed by interactions between proteins of the ovarian fluid and proteins of the zona radiata externa (ZRE) leading to the egg attachment with each other. This mechanism is unique in teleost fish and is described for the first time in the present paper.
欧亚鲈（河鲈）的鱼卵彼此紧密相连，形成了长0.5 - 5.5米、宽1 - 6厘米的漂浮胶状条带或丝带。本研究对鱼卵附着开始时所涉及的过程进行了调查。鱼卵与少量卵巢液一同排出。当鱼卵与水接触时，卵巢液中的蛋白质与外部放射带（ZRE）的蛋白质相互作用，形成一种纤维状的胶状结构，从而导致鱼卵相互附着。这种机制在硬骨鱼中是独一无二的，本文首次对此进行了描述。
