摘要/Abstract

摘要： 以一种新兴的海洋模式生物海水青鳉(Oryzias melastigma)为研究对象，采用4种人造海藻模拟了自然海藻影响海水青鳉产卵的生态作用。结果表明：海藻对海水青鳉产卵具有明显的促进作用；两两交叉放入人造海藻，海水青鳉在球状或海葵状海藻的挂卵量显著高于其他人造海藻(P<0.01)；4种人造海藻同时存在时，海水青鳉几乎不在玻璃空地产卵，在球状海藻的挂卵数最高(176±47 eggs·d^-1)，其次为海葵状海藻(89±32 eggs·d^-1)，显著高于树状海藻和大叶海藻(P<0.01)；球状海藻和海葵状海藻上的挂卵数呈现出此消彼长的动态，最终海葵状海藻的挂卵数超过了球状海藻。由此推测，海水鱼类在产卵过程中对海藻的物理结构具有明显选择性。本研究结果为进一步开展中国海洋渔业资源修复工作提供了一定的理论依据。

Abstract:

This study was undertaken to evaluate the effects of four different types of artificial seagrass onOryzias melastigmareproduction. The results indicated that daily egg production ofO. melastigma was significantly affected by artificial seagrass. When every two types of seagrass were added together, more eggs were found on globular artificial seagrass or artificial seagrass shaped like sea anemone than on other types of artificial seagrass (P<0.01). When the four types of artificial seagrass were added together, the number of eggs pooled from globular artificial seagrass (176±47 eggs·d^-1) and artificial seagrass shaped like sea anemone (89±32 eggs·d^-1) were significantly higher than that from the others. Besides, the number of eggs presented a reciprocal dynamic trend on different types of seagrass. The number of eggs on artificial seagrass shaped like sea anemone was increased, and eventually exceeded the number of eggs on globular artificial seagrass. It is speculated that marine fish is obviously selective to physical structure of seagrass during the process of laying eggs. Our study provides certain basis for the restoration of fishery resources.
