爱荷华州 DNR 收集大眼鱼卵，生产近 1.16 亿只鱼苗，以增加该州的鱼类数量。 Iowa DNR collects walleye eggs, producing nearly 116 million fry to boost the state's fish population.

爱荷华州自然资源部 （DNR） 今年春天成功收集了大眼鱼蛋，由于自然繁殖不足，生产了近 1.16 亿只鱼苗，以维持该州的大眼鱼种群。 The Iowa Department of Natural Resources (DNR) successfully collected walleye eggs this spring, producing nearly 116 million fry to maintain the state's walleye population, as natural reproduction is insufficient. 这项工作涉及捕捉成熟的鱼,收集鸡蛋,并在孵化厂饲养煎鱼,然后再在爱荷华河上种鱼。 This operation involves capturing mature fish for egg collection and raising the fry in hatcheries before stocking them across Iowa. 该方案的成功确保了长眼渔业蓬勃发展,并取决于国家自然资源局工作人员的协调努力。 The program's success ensures a thriving walleye fishery and depends on the coordinated efforts of the DNR staff.
