一、干早地区山塘渔业的现状我市属丘陵山区,全市辖九县一郊,水资源利用率低,旱涝保收的水田仅占总水面积的56.81％。全市山塘水面30万亩、“天水塘”的面积就有4.8万余亩。这些山塘由于集雨面积小,而且大部分还担负者农田灌溉任务,因此常年蓄水时间只有3—4个月。由于基础条件差,养鱼效益低,多数群众不愿意利用这些水面养鱼,有些地方即使按一般的养殖方式,投放家鱼种养鱼,但由于养殖时间短,产量很低,一般亩产只有几十公斤,相对成本高。如何充分开发利用这些水面养鱼,提高单产,增加总产,已成为加快发展丘陵山区山塘渔业的重要课题。二、利用革胡子鲶开发干旱地区山塘 First, the status quo of mountain pond fishery in dry areas The city belongs to the hilly and mountainous areas, and the whole city has jurisdiction over the outskirts of nine counties. The utilization rate of water resources is low, and paddy fields covered by drought and flood only make up 56.81% of the total water area. The city pond water 300000 mus, “Tianshuitang” area has 48000 acres. Due to their small rain-collecting area and the majority of these ponds are also responsible for farmland irrigation, the perennial storage time is only 3-4 months. Due to poor basic conditions and low efficiency of fish farming, most people are reluctant to use these aquatic fish culture. In some places, even if fish are raised and raised by ordinary fish farming methods, due to short breeding time and low yields, Dozens of kilograms, the relative high cost. How to fully exploit and utilize these fishmeal, raise yields and increase total output has become an important issue for accelerating the development of pond fisheries in hilly and mountainous areas. Second, the use of leather catfish to develop dry areas ponds
