Pikeperch (Sander lucioperca L.) is an important species for European aquaculture and recreation fisheries. The wide range overexploitation of its stock highlights the importance of supporting wild stocks, within its native range. Our study was therefore addressed to test the effectiveness of different artificial spawning nests in a natural habitat. Eight types of artificial nests, characterized with different shape, size and substrate were tested in six localities of Lake Balaton (Hungary), in order to revel the difference between their effectiveness and usability. Nest occupancy was recorded and number of eggs on each nest was calculated and compared. Artificial spawning nests proved to be highly effective for pikeperch spawning under natural conditions, even on suboptimal bottom substrate conditions. Nest size seems to be an important factor: our results suggest at least 0.5 m² substrate area may be required.

梭鲈（Sander luciopercaL.) 是欧洲水产养殖和休闲渔业的重要物种。其种群的广泛过度开发凸显了在其原生范围内支持野生种群的重要性。因此，我们的研究旨在测试自然栖息地中不同人工产卵巢的有效性。在巴拉顿湖（匈牙利）的六个地方测试了八种不同形状、大小和基材的人工巢穴，以了解它们的有效性和可用性之间的差异。记录巢穴占用情况，并计算和比较每个巢穴上的鸡蛋数量。事实证明，人工产卵巢在自然条件下对梭鲈产卵非常有效，即使在次优的底部基质条件下也是如此。巢大小似乎是一个重要因素：可能需要^{2 个}基板面积。
