topographic engineering requirements of fish ponds Technical aspects In addition to the six socio-economic conditions mentioned above, technical requirements are also important to note. Requirements of this technique include topography, soil, and water. 1. Topography Topography is the overall shape of the land surface (flat, undulating or steep). Topography is our spotlight for the first time will determine the type, area, number, and the depth of the pond which will be made. Sloping land once, can not be built units will form the pool for a small pond and the embankment will be wide. This broad embankment works to hold a large mass of water collected underneath. Similarly, if the soil is too flat, it will cost to dig a big land. It also would complicate disposal of water (drainage). There are six types of places that have character and a special utility for making the pond, which is V-shaped valleys and essentially flat valley ' a. V-shaped valley sharp Do not ever make a fish pon...

Pests and disease prevention in fish Catfish Sangkuriang Just like other fish, catfish sangkuriang not be separated from the threat of pests and diseases. Disease affecting sangkuriang catfish most often caused by environmental conditions that are less supportive, such as water quality (especially temperature) under standard or stress due to the fault handling sick fish. Meanwhile, the usual pests attacking sangkuriang catfish include snakes and eels, while organisms that attack pathogenic form Ichthiophthirius sp., Trichodina sp., Monogenea sp., And Dactylogyrus sp.
