I. Introduction.The fish is a fish species of high-producing animal protein. Intensification of farming needs to be done because of the low productivity of milk with traditional farming. Improved farming systems should also be followed by the use of new technologies.PT. NATURAL NUSANTARA provide the necessary technology to the principle of K-3 (Quantity, Quality and Health).
II. Biological properties.Banding group include herbivorous fish, the fish that eat the plants. Able to achieve an average weight of 0.6 kg at age 5-6 months in intensive care.
III. Provision of Seed.Seed supply business (nener) continuously with a good quality system is carried out with intensive hatchery ponds in particular, the pool of stem maturation, spawning, and swimming pembsaran peneneran. In milkfish hatchery steps taken were:A. The selection of superior parent. Superior parent will lose their properties to their offspring, Characteristics:- Normal shape, length and weight ratio ideal.- Head size is relatively small, between one of the fastest growing hybrid.- Orderly arrangement of scales, smooth, shiny, no injuries.- Nimble and normal movement.- Age between 4 and 5 years.
2. Stimulate spawning. Gonad maturation can be accelerated by the use of hormone LHRH (Hormone Releasing Hormone Letuizing) by injection. '
3. Breeding. Spawning is mixing the male and berina a mature sperm cells and egg cells that occurs expenditure (ejaculation) the second cell. After being on the water, sperm will fertilize an egg for fertilization systems of fish occurs outside the body. Spawning is done in special spawning ponds
4. Hatching. Eggs that float in the pool spawning hatch after 24-26 hours from the beginning of spawning. Eggs will hatch into larvae that still have food reserves from the yolk stem, so do not need to be fed until the age of 2 days.
5. Treating the seed. After 9 days old larvae was transferred to a pool maintenance nener. In this pool of larvae fed natural plankton. Growth of plankton carried by fertilization and liming. Proper fertilization with manure is a TON (POND ORGANIC NUSANTARA) containing various mineral elements essential to the growth of plankton, such as N, P, K, Mg, Ca, Mg, S, Cl, etc., are also equipped with humic acid and vulvat the mempu improve texture and increase soil fertility bottom of the pool with a dose of 5 bottles TON / ha or 25 grams (2 tablespoons) / 100 m2 on each entry of water. Peneneran time 8 weeks. Feed given in the form of flour with a protein content of 30%. To add nutrients to feed pencampuiran feed by NASA with a dose of 2-5 / kg of feed is necessary, because NASA contains essential mineral elements, namely N, P, K, Mg, Fe, Ca, S and others, vitamins, protein and fat to enhance the growth and health nener.
IV. Enlargement.After peneneran maintained in the pool for 8 weeks, milkfish transferred to rearing ponds. Technical enlargement banding involves several things, namely:A. Tillage.This stage is carried out before the water inlet. activities undertaken during the preparation of the land is:- Break ground and ground reversal. Aims to liberate the rest of the compounds and toxic gases of decomposition of organic cultivation of both food and of excrement. In addition to a gemburnya soil, aeration will go well so that the fertility of the land will increase.- Liming. During cultivation, fish require a stable acidic conditions at pH 7-8. To restore the condition of the soil acidity, liming performed because of the accumulation and decomposition of organic materials during the previous cultivation lowers soil pH. Calcification also causes the disease-carrying bacteria and fungi die because it is difficult to live on the pH. Liming with calcium oxide, dolomite or a zeolite with a dose of 1 TON / ha or 10 kg/100 m2.- Fertilization. The main function of fertilization is to provide the necessary nutrients for the growth of natural food, improve soil structure and prevent infiltration of water on land that is not water (porous). The use of TON for fertilizing the soil bottom of the pool is very appropriate, because it contains a TON of essential mineral elements, and organic acids provide the main ingredients needed to increase soil fertility and the growth of plankton. TON fertilizer dose is 5 bottles / ha or 25 gr/100 m2.- Water management. after fertilization with TON, water added up to as high as 10-20 cm and then left for some days, to cultivate the seeds of plankton. Air is inserted up to as high as 80 cm or adjust the depth of the pool.
2. Nener removal. After the plankton growth (green water color) and brightness as deep as 30-40 cm, in the pool peneneran nener transferred to rearing pond cautiously with adaptation to new environments.
3. Provision of feed. According to the nature of the banding that includes herbivore animals, then these fish like to eat plants in the pond. Banding is the preferred plant moss, algae and klekap. To accelerate growth, the need to feed factory-built, with standard nutrients needed for optimal growth with protein levels. A minimum of 25-28%.
As herbivores, plants in the feed element is very important. Therefore, the raw material should be dominated by elements of protein from plant or vegetable sources of soybean meal or peanut meal. As reference feeding are: The amount of feed 5-7% of body weight. Delivery time 3-5 times a day.
The addition of NASA on artificial feed is the right choice to enhance the growth and endurance banding. NASA contains essential minerals, protein, fat and vitamins will increase the nutrient content of feed. NASA dosage mixing with artificial feed is 2-5 cc / kg of feed by the way:A. Weigh the feed in accordance with the requirements of milkfish.2. Moisten food with less water for mixing with NASA can be evenly distributed.3. Mix the appropriate amount of feed that NASA is given a dose of 2-5 cc / kg of feed.4. The feed is ready to be given.Feeding by spreading them evenly throughout the pool area, so that the whole milk to feed.
V. Control of pests and diseases.Important disease that often affects banding are:A. Fin rot, caused by bacteria. Symptoms from the edge of the fin rot.2. Vibriosis. Vibriosis sp caused by bacteria, the symptoms decreased appetite, fin rot, and the abdomen swollen with fluid.3. Disease by Protozoa. Symptoms are loss of appetite, blind eyes, flaky scales, gills damaged, a lot of mucus.4. Disease by microscopic worms. Diploctanum often caused by a worm that attacks the gills so that it becomes pale and slimy.Illness from bacteria, parasites and fungi due to bad neighborhoods, and lower resistance of fish. Environmental degradation caused by the high accumulation of organic materials and environmental pollution of the river .. Organic material and dirt will rot and manghasilkan harmful gases. Determined resistance of the fish body nutrient consumption. Then the disease control measures should focus on both factors. To address the decline in environmental quality can be done a TON of treatment with a dose of 5 bottles / ha or 25 grams (2 tablespoons) / 100 m2 that contain trace elements and organic acids is important that neutralizes various harmful gases results in a pool of filth and decay of trace elements will fertilize the plankton as natural feed. To provide for an ideal nutrient amounts, should be given feed with appropriate protein standards and with the addition / mixing of NASA on artificial feed. NASA with the content of important minerals, vitamins, organic acids, protein and fat will add to and complement the feed nutrients, so the resistance of the body to grow and thrive is always fulfilled.
