Fish spawning field, bait field and hiding field building method
A fish spawning field, bait field and hiding field building method comprises the steps that S1, the downstream terrain of a dam is analyzed, and an artificial spawning field center line suitable for building a stepped spawning field is determined; s2, excavation is conducted along the center line of the artificial spawning site determined in the step S1, an artificial spawning site riverbed is formed, water flow is introduced into the artificial spawning site riverbed, and the artificial spawning site is obtained; s3, creating a fish spawning and roe hatching environment in the artificial spawning site; s4, creating a juvenile fish inhabiting environment in the artificial spawning site; s5, water temperature and water flow regulation and control are conducted on the artificial spawning site. According to the spawning site provided by the invention, enough spawning sites and bait fields are created for adult fishes, stable and appropriate water flow and water temperature conditions are provided for fish egg incubation, and rich bait and hiding growth environments are provided for juvenile fishes.
一种鱼类产卵场、索饵场和藏匿场营造方法，步骤包括：S1、对大坝下游地形进行分析，确定适宜修建梯级产卵场的人工产卵场中心线；S2、沿着步骤S1确定的人工产卵场中心线进行开挖，形成人工产卵场河床，并向人工产卵场河床中引入水流，得到人工产卵场；S3、在人工产卵场中营造鱼类产卵和鱼卵孵化环境；S4、在人工产卵场中营造幼鱼栖息环境；S5、对人工产卵场进行水温、水流调控。本发明所提供的产卵场，为成鱼营造足够的产卵场、索饵场，为鱼卵孵化提供稳定的、适宜的水流、水温条件，为幼鱼提供丰富的索饵和藏匿生长环境。
