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

Living Conditions and Life Habits Patin very tolerant of acidity (pH) of water. This fish can survive in waters with a degree of acidity is slightly acidic (low pH) to the alkaline waters (high pH) with pH 5-9. Oxygen content (02) solute needed for the life of catfish are 3-6 ppm. Levels of carbon dioxide (CO2) that can ditoleran is 9-20 ppm. The required level of alkalinity 80-250 ppm. Meanwhile, the optimal water temperature for the growth of catfish is 28-30 ° C. In its original habitat, the fish is always hiding in holes. As fish nocturnal (active at night), a new catfish out of his hiding hole when it was getting dark.
