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...

Prawns Prawns (Macrobranchium rosenbergii), including one of the leading commodity fisheries freshwater cultivation of high economic value, but has not developed to its optimum. Currently, besides local prawns are usually cultivated farmers, high yielding varieties also known as prawns gimacro (genetic improvement of macrobranchium rosenbergii) with a faster growth rate and form karapasnya smaller than the size of local prawns karapas that contain meat more. At the age of five months, the body length of male prawns gimacro reach 38 cm in body weight reached 480 grams per fish. Meanwhile, in the same period, the length of the body of local prawns reaching only 25-28 cm in body weight of only 200 grams per fish. In fact, the maximum size of local prawns ever found in the wild only 300 grams per tail. That's why gimacro prawns prawns known as super because pertumbuhanya very quickly. prawns added value options when maintenance is relatively brief, lasting from 3 to 5 months. Productio...
