Abstract

The fertilized eggs of cuttlefish are sticky eggs. Cuttlefish parents prefer to lay eggs on the attached substrates, which help increase the number of eggs and the hatching rate of fertilized eggs. If egg-attached substrates are sufficient, cuttlefish spawning will be reduced or even delayed. With the advances in the construction of marine nature reserves and research on artificial enrichment techniques, domestic and international experts have conducted research on different types and configurations of attachment substrates around cuttlefish resource enhancement. Based on the source of the substrates, we classified cuttlefish spawning substrates into two types, natural and artificial. By summarizing the differences, advantages, and disadvantages of the common economic cuttlefish spawning substrates in offshore areas worldwide, we sort out the functions of two different types of attachment bases, and discussed the practical applications of natural and artificial egg-attached substrates in spawning ground restoration and artificial enrichment. We proposed several thoughts on the future research directions of cuttlefish spawning attachment substrates, aiming to provide reasonable suggestions for cuttlefish habitat restoration, cuttlefish breeding and sustainable development of fishery resources.

乌贼类受精卵为黏性卵,乌贼亲体偏好于将卵产在附着基上,适宜的附着基有助于提高亲体产卵数量和受精卵孵化率。在没有充足附着基的情况下,乌贼类产卵数量将会减少甚至推迟产卵。随着海洋自然保护地建设和人工增养殖技术研究不断推进,国内外专家学者围绕乌贼类资源增殖,对不同类型和不同构型的附着基进行了研究。本研究基于乌贼类的产卵繁殖习性,依据附着基的来源,将乌贼类产卵附着基分为天然和人工两种类型,通过对比分析,从相同点、不同点与优劣势角度对全球范围内近海常见经济乌贼类产卵附着基进行总结,梳理了两种不同类型附着基的功能,并论述了乌贼类产卵附着基在天然产卵场修复和人工增养殖中的实际应用。在全面了解乌贼类附着基的同时对未来研究方向提出了几点思考,旨在为乌贼类的生境营造、增养殖以及渔业资源的可持续发展提出合理建议。.
