摘要：为提高育苗成活率，并获得较为稳定的育苗效果，本研究通过增加恒温流水装置改良孵化设施，利用遮光挡雨设施保持室外大型水泥池相对稳定的育苗水体条件，开展点蓝子鱼室外大水泥池育苗试验。结果显示，3批次人工催产，孵化率在原有不足80%的基础上获得有效提高，分别达89.4%、92.1%和91.2%，育苗成活率分别为23.5%、30.4%和28.5%。通过这种室外大型水泥池育苗模式，克服了室内水泥池出苗量不足及传统池塘育苗受自然环境影响大等缺点，育苗效果稳定、良好，可操作性强。

Abstract: In order to increase breeding survival rate and get stable breeding results, the breeding trial of Siganus guttatus in outdoor cement pool was carried out, in which the running water unit with constant temperature was used to improve the incubation facilities and shielding facilities were applied to maintain stable breeding water environment in outdoor large cement pool. The results showed that the hatching rate of Siganus guttatus was effectively increased with the hatching rate of 89.4%, 92.1% and 91.2% in three batches, while it was less than 80% in the traditional way. 82,000(3.8 cm in total length), 174,000 (3.5 cm in total length) and 179,000 (3.4 cm in total length) fries were gained in the three batches, with the breeding survival of 23.5%, 30.4% and 28.5% respectively. The results of the trail indicated that the new breeding model of outdoor cement pool avoided the disadvantages of low seed production volume in indoor cement pool system and uncontrollable environments of traditional pond breeding system, and had the characteristics of stable and sufficient seed supply, easy for operation.
