Fish Farming Opportunities
Fish farming is an activity that is very important today and in the future. This is because the fish is one type of food needed by the man who has a sales price that is relatively inexpensive and have a complete nutritional content.By eating fish is a human nutritional needs will be met. Therefore, human resource capacity to produce farmed fish is needed. This caused a number of factors including. Due to the increasing number of consumers who are accompanied by a decline in the catch of marine fish caused by the proliferation arrest that can not be in tolelir, and also because of the frequent occurrence of waste pollution in sea water thus inhibiting the proliferation of fish.

With the increasing population and limited land cultivation, it takes a fish farming technology on a limited land and high productivity to meet food needs. Development of fish cultivation in Indonesia has started since 1969. However, intensive cultivation began to flourish in the 1990s related to the widespread cultivation of indigo in Floating Net Cage. Development of intensive aquaculture in Indonesia have not been so encouraging as several factors, among others, the low efficiency of production and low market prices in addition to the provision of quality seeds and stem.Assessment of fish farming technology in support of the intensification of cultivation was aimed at increasing production efficiency, in order to improve price competitiveness. Several efforts related to technology assessment including the assessment of hatchery techniquesBoarding Nurul Iman Al Ashriyyah now being built using the method of cultivation Aquaculture Fibber glass media. Aquaculture is the cultivation media using a rotational system of water regulation, so it can be applied in areas that are less productive. In addition Aquaculture also has some advantages include the following:
A. Facilitate monitoring at each

Business Opportunity Fish Cultivation alone can enable the various forms of business, including:- Business Hatchery- Enlargement Business
Seeding
Seed requirements in line with the needs of red tilapia consumption, the greater the consumption needs of the need for tilapia seed thus increasing business opportunities open in terms of red tilapia breeding. Breeding methods are also relatively easy, because the red tilapia can breed naturally with great ease. Just what is needed is a wide area. Red tilapia will grow very rapidly in rice acreage is shallow and wide with the water temperature is warm enough.
Enlargement
Enlargement is one of the fish in the fish farming process which aims to obtain the size of fish consumption. On the cultivation of fish rearing is a business segment that is mostly done by the farmers. In doing this the fish rearing is relatively not too difficult because of the skills required are not as difficult as doing the fish hatchery.
THINGS TO LOOK IN THE MIND POWER OF FISH
I. AIR QUALITY MANAGEMENT
Quality management is a way of controlling the condition of water in the pond culture in such a way that meets the requirements of life for the fish to be maintained. In the cultivation of tilapia in the pond so the fish can grow and develop the culture pond water conditions must be in accordance with the requirements of tilapia. Water quality is highly variable effect on tilapia include:
1 The temperature of the water.Water temperature is an important factor to consider because it can affect the body's metabolic rate in fish. At high temperatures the metabolic rate will increase, whereas at low temperatures the metabolic rate will decrease.With the optimal temperature the metabolic rate would be optimal. Tilapia growth is strongly influenced by water temperature in rearing or breeding business. Water temperature affects the activity of the digestive tract of tilapia seed.Natural food in the form of detritus and fauna complete basis digested in 1.68 hours at a temperature 27 - 28oC and 1.31 hours at a temperature of 32-33 oC. At temperatures 27 - 28oC to feed zooplankton ingested within 2.2 hours. Fish can ingest food for 2.5 - 3 hours at a temperature of 30oC. Based on these results the optimum temperature for growth of tilapia is 25 - 30oC.
2. Volume of waterTilapia growth is maintained in the water to flow more quickly than those kept in stagnant water. Under conditions of water flows, tilapia with initial weight of 9.1 grams were fed pelleted 25% protein and feeding rate is 3.5% within a week to reach the weight of 34.2 grams. Besides determining the volume density of water is optimal tilapia. Density of tilapia in ponds is 30 individuals / m 2.
3. Dissolved oxygen levelsTo be able to live human beings need oxygen as well as fish. Oxygen that fish need to live in water is called dissolved oxygen.Tilapia is a fish that is resistant to lack of oxygen dissolved in water, but the growth of these fish would be optimal if the dissolved oxygen content over 3 ppm. Dissolved oxygen content of less than 3 ppm can cause fish can not grow and eventually die.
4. Salt content (salinity)Tilapia has a wide salinity tolerance, but the growth of tilapia in the salinity of more than 30% will be hampered. At high salt content of fish require minimal energy for osmoregulation, so the energy used for growth decreased.
