在中国南方某海水养殖基地的3个海藻-龙须菜-贝类综合养殖区（G）、鱼类养殖区（F）、贝类养殖区（S）以及邻近对照海区（C）的表层和次表层沉积物中，研究了哲水蚤类桡足类和轮虫休眠卵对浮游生物种群的潜在补充作用。C和G沉积物中桡足类和轮虫卵的潜在补充量显著高于F和S。未观察到F和S在次表层沉积物中的潜在招募，这表明鱼类和贝类海产养殖可能是造成这种减少的原因。桡足类和轮虫休眠卵孵化成功率受养殖类型的影响，如果采用综合养殖，规模化海藻养殖可以抵消鱼贝养殖对休眠卵的不利影响。
The potential recruitment of resting eggs of calanoid copepods and rotifers to planktonic populations was investigated in the surface and sub-surface sediments of three mariculture zones: an integrated seaweedGracilarialemaneiformisand shellfish cultivation area (G), a fish cultivation area (F), and a shellfish cultivation area (S), as well as the sediments of a nearby control sea area (C) in a mariculture base in Southern China. The potential recruitment of copepod and rotifer eggs in the sediments of C and G was significantly higher than in F and S. Potential recruitment in the sub-surface sediments of F and S was not observed, suggesting that fish and shellfish mariculture may be responsible for this decrease. The hatching success of resting eggs of copepods and rotifers was affected by mariculture type, and that large-scale seaweed cultivation may offset the adverse effect of fish and shellfish cultivation on the resting eggs if integrated cultivation is adopted.
