Culture attachment substrate for improving culture survival rate of crayfishes

The utility model provides a culture attachment matrix for improving crayfish culture survival rate, which comprises a floating part, a submerged part and a plurality of attachment meshes, the plurality of attachment meshes are distributed between the floating part and the submerged part at equal intervals, and two opposite sides of each attachment mesh are respectively fixed on the floating partand the submerged part through fixing parts. The attachment substrate is simple in structure, convenient to use and capable of stably achieving the purpose that a proper shielding place exists in thecrayfish shelling period, crayfishes are prevented from mutual food residue, the crayfish breeding survival rate is increased, the breeding risk is reduced, and the breeding benefits are increased. 本实用新型提供了一种提高小龙虾养殖成活率的养殖用附着基体，包括漂浮件、沉水件和附着网片，附着网片有多个，多个附着网片等间距分布于漂浮件和沉水件之间，各附着网片相对的两侧分别通过固定件固定于漂浮件和沉水件上。该附着基体结构简单，使用方便，能够稳定的实现小龙虾蜕壳期间有适宜的遮蔽场所，避免小龙虾相互残食，提高小龙虾养殖成活率，降低养殖风险，提高养殖效益。
