在新疆和田县的沙漠水产养殖基地里，养殖工人正划着小船，穿梭在水塘里起网收蟹。养殖工人告诉记 者，现在正值螃蟹捕捞高峰期，平均一天的捕捞量在500公斤左右。 （央视财经《天下财经》）新疆和田地区位于塔克拉玛干沙漠边缘，近年来，当地通过盐碱地改造技术 成功实现多种水产品的规模化养殖。这段时间，当地养殖的螃蟹、鲈鱼等开始批量上市。 新疆和田县沙漠水产养殖基地工作人员 赖君：螃蟹产量今年预计可能是在40吨左右，鲈鱼产量大约有 30吨，蓝龙虾可能稍微要少一点，产量是几吨，预计总产量可能是在70多吨。 总台记者 卜鹏：和田县通过改造盐碱沙地，不仅成功在沙漠边缘培育出优质的螃蟹，更实现了鲈鱼、 龙虾等水产品的规模化养殖，独具特色的"沙漠海鲜"养殖产业在这里得到快速发展。 这两年，和田县通过降盐脱碱、循环淡水及益生菌调节等技术，将养殖用水pH值稳定在适宜范围，成 功养殖了多种水产品，目前，这些水产品都已经进入捕捞高峰期。 总台记者 卜鹏：这些螃蟹是在今年3月份投放到水塘里，经过7个月的生长，如今已经迎来了捕捞上市 的季节。这几年当地的农户通过科学引水、改良沙地，让曾经的这片沙地变成了优质的水产养殖基地。 养殖基地的技术负责人 ...
