摘要我们比较了2004-2007年间放养在威斯康星州湖泊中的两种不同大小的大眼沙鱼鱼种的性能。6月份放养的小鱼种总长度为1.0-2.0英寸。9月份放养了长度为7.0-8.0英寸的大型鱼种。研究湖泊的面积从120英亩到515英亩不等，分布在全州的南北两端。在放养后的春天里，我们用一个吊篮和两个勺子对每个研究湖的整个海岸线进行了电捕。大规格鱼种的平均1龄渔获量(CPE)(11.2/mI)显著高于小规格鱼种(2.8/mI)。该州的地理位置与年龄-1岁的CPE没有显著关系。在12个大的鱼种放养事件中有11个检测到了放养年级，但在12个小的鱼种放养事件中只有7个被检测到。年龄为1岁的袋鼠的总长度与放养时的大小没有显着的相关性，但在不同的地点有显着的差异。长袜大眼袋..。
Abstract We compared the performance of walleye Sander vitreus fingerlings of two different sizes that were stocked into Wisconsin lakes during 2004–2007. Small fingerlings were stocked in June at a total length of 1.0–2.0 in. Large fingerlings were stocked in September at a length of 7.0–8.0 in. The study lakes ranged from 120 to 515 acres in surface area and were dispersed north and south across the state. We electrofished the entire shoreline of each study lake with a boomshocker and two dippers during the spring after stocking. The mean age-1 catch per effort (CPE) was significantly higher for large fingerlings (11.2/mi) than for small fingerlings (2.8/mi). Location in the state was not significantly related to age-1 CPE. Stocked year-classes were detected for 11 of 12 large-fingerling stocking events but only 7 of 12 small-fingerling stocking events. The total length of age-1 walleyes was not significantly related to size at stocking but varied significantly among locations. Stocking large walleye fi...
