This research was designed to find out the effect of different factors such as influence of lunar cycle, harvesting interval, rope type and seeding gap on the production of G. tenuistipitata in coast of Cox's Bazar. Duration of these experiments were sixty days and all the parameters were recorded fortnightly. Monitoring of water quality parameters indicated that salinity, temperature, transparency, pH and DO were suitable for seaweed cultivation. In determining lunar cycle effect, results envisaged that fresh yield was 14.43% increased when seeding and harvesting time was selected considering the moon cycle. Regarding the selection of harvesting interval, it was found that T (30 days interval) was the best to harvest the seaweed whereas T (40 days interval) showed decreasing trend in production. Our study also found that semi floating single line showed better yield performance compared to semi floating double line system. In case of influence on seeding gap, it has been found that 20 cm gap between two seed showed the highest yields followed by 10 cm, 30 cm and 40 cm, respectively. Overall, it can be concluded that yield of G. tenuistipitata in coast of Cox's Bazar could be improved considering those factors.
本研究旨在探讨月球周期、收割间隔、绳索类型和播种间隙等因素对考克斯巴扎尔海岸产细基江蓠产量的影响。这些实验的持续时间为 60 天，每两周记录一次所有参数。水质参数监测表明，盐度、温度、透明度、pH 值和 DO 适合海藻养殖。在确定月球周期的影响时，结果表明，当根据月球周期选择播种和收获时间时，新鲜产量增加了 14.43%。关于收割间隔的选择，发现 T（30 天间隔）是收获海藻的最佳时间，而 T（40 天间隔）显示出产量下降的趋势。我们的研究还发现，与半浮式双线系统相比，半浮式单线显示出更好的产量性能。在播种间隙的影响方面，发现两株种子之间的 20 厘米间隙表现出最高的产量，其次是 10 厘米、30 厘米和 40 厘米。总的来说，可以得出结论，考虑到这些因素，考克斯巴扎尔海岸的细基江蓠产量可以得到提高。
