Jelawat fish reproduction. Jelawat fish begin spawning at the beginning of the rainy season, which is in October-November. During the rainy season, jelawat able to spawn spawning 2-3 times. When rain and rain water flooded the surrounding area, jelawat began to spawning. The fish are mature gonads migratory into estuaries and perform spawning morning accompanied rintikan rainwater. Jelawat egg is floating. The fertilized eggs were then taken to the water flow downstream and hatch during the trip. Children jelawat measuring 2 cm -3 will arise to the surface of the water and swim in droves along the banks of the river, upstream against the current. While children jelawat size 4- 5 cm glad to be in places that are protected from sunlight that water is rather calm. Jelawat can spawning naturally in ponds, but only spawn at the start of the rainy season. Jelawat fish do not spawn outside the rainy season. To overcome that is then applied to the artificial spawning techniques (induced breeding) by way hipofisasi (use of the pituitary gland) and some sort of synthetic hormone ovaprim. Jelawat has successfully dihipofisasi in early 1978 by LPPD Bogor. 2004 BBI Pavilion, West Kalimantan, has succeeded in producing seeds in bulk jelawat. While BBAT Jambi successful breeding of mass jelawat since 2006.

Food and fish Eating habits Jelawat

Jelawat fish including species of fish omnivorous (omnivores but are more likely to eat plants or tend herbivores (plant-eating) fish food jelawat as seeds of fruits, flowers and young leaves of aquatic plants and small animals in water. While the kids jelawat like plankton, algae, aquatic insects and larvae. In fish farming, fish jelawat can be given cassava, cassava leaves, papaya leaves, taro leaves, coconut pulp, chicken intestines meat that has been minced fish , and so on. To use the pellets as feed in aquaculture jelawat preferably contains between 25-30% protein were given as much as 3-4% of the total weight for enlargement. As a pet parent to be given pellets containing 35-38% protein as much as 2 -3 % total weight of fish. From the shape of the mouth known that jelawat prefers to drift Jelawat food including fish that feed by grabbing way.

MINA CHICKEN. Mina chicken (fish and chicken) is one of the integrated aquaculture business, business management system mina chicken is no different with the management of fish farming in ponds, while raising chickens as is generally done. Chicken coop built on top of the pool or at the edge of the pond fish so chicken manure and leftover chicken feed will fall into a fish pond. The advantages of integrated fish farm chicken mina, among others, (a) utilize the vacant land area above the fish pond; (B) utilizing the chicken manure is used as fertilizer for the pond; (C) chicken food scraps that fall into the pool can be used to feed the fish; and (d) the use of land for fisheries and livestock diversification. Shortage of integrated fish farm chicken mina among others, (a) which have not been dried chicken manure which falls into the pool cause odor; (B) if the rest of the chicken manure and residual feed falls into the pool can lead to excessive enrichment of the pool so that there will be an explosion of plankton (plankton bloom): (c) fish cultivation usually smells because chicken manure as well as enrichment in the pond, and (d ) fish yields should diberok prior to cleaning. Fish farming system mina chicken is done to produce seed (listeners Deran) and fish consumption (enlargement). Nursery activities in an excellent chicken mina system because the amount of natural food that many

Damselfish

damselfish. damselfish (Anabas testudineus) is a native species of fish common Indonesian waters. In Borneo, the damselfish is a freshwater fish of high economic value and has a high price. In East Kalimantan, the price is very high consumption damselfish, reaching Rp70.000,00 - Rp100,000,00 / kg, while in Sumatra between Rp 20.000,00 / kg - Rp40.000,00 / kg. This fish is very easy to be cultivated because it can live in stagnant waters minimal oxygen lack of oxygen. In Borneo and Sumatra, damselfish is one freshwater fish arrest in nature very intensive, This is seen from the damselfish production in some areas continues to increase each year. In East Kalimantan, in 2004 the production of the damselfish 91 tons increased to 150 tonnes in 2005. Prices are high damselfish encourage intensive arrest so feared causing over fishing that will ultimately threaten the damselfish populations in the wild.

Swamp

Swamp. Swamp is an area of low land which always has a sensitivity of stagnant water at a certain time and throughout the year. Swamp water sources include rainwater, water overflow due to the propagation of tides and water overflow flooding upstream. Based on water resources, wetlands can be divided into tidal marsh and nonpasang downs. Tidal marsh is low land water bodies dipengaruh by tidal movement. Tidal marsh water bodies in direct contact with the river so that the acidity is reduced. Habitat conditions are relatively fertile and inhabited by more aquatic organisms. Species composition of aquatic fauna that inhabit the marsh area is dominated by the river fish. Moving water bodies in accordance with the movement of the tide. This opens the possibility to apply the method of raising fish in the river, which is the method cage and tidal pools. While nonpasang receding swamp called the Valley is an area that has a low sensitivity and stagnant water from rainfall or overflow flooding upstream. Nonpasang bog downs have a stable water bodies and water acidity levels are still high that only organisms that are resistant to high acidity that can live. In other words, the body of non-tidal water ra relatively thin. The population of aquatic biota dominated swamp fish, which is a type of fish that are resistant to acidity and low oxygen content such astringent, catfish, cork, toman, gouramis, carp, and damselfish. Maintenance methods that can be applied is rain-fed pond (pond rainfed) and lowland farms

Catfish in indonesia

Catfish. Catfish (Clarias sp) is a freshwater fish the second most widely produced in Indonesia through aquaculture. In 2010, production reached 270.6 thousand tonnes of catfish. There are three species of catfish are grown in Indonesia, namely the African catfish (Clarias gariepinus), local catfish (c. Batrachus), and catfish keli (c. Maladerma) African catfish is an introduced species, while the local catfish and catfish keli are native species. In addition, it has produced two varieties of catfish superior, namely catfish and catfish sangkuriang phiton. Catfish is one of the superior fish that can be cultivated in various containers and aquatic environment, and can be stocked with high density.

Populer fishes

ruliyandi@gmail.com (ruliyandi) — Wed, 8 Apr 2015 06:44:00 +0700

Popular fishes. Among freshwater fish cultivated, some species are popular fish, either because it is the most widely cultivated fish, lead fish, or as a food fish that has long been known. a. Goldfish. Carp (Cyprinus carpio) is the oldest fish in the history of freshwater aquaculture in Indonesia. Even goldfish is the most widely cultivated fish in Indonesia until 2003. In 2003-2004 carp aquaculture in Indonesia experienced a disease KHV (Koi Herpes Virus) are terrible. Until late 2004, the center of cultivation centers carp was destroyed, however, the cultivation of carp remain in demand. In 2010, the national fish production reached 267.1 thousand tons, which ranks third after tilapia and catfish. b. Nila. Currently tilapia (Oreochromis nilotica) is the belle of freshwater fish in Indonesia. National tilapia production in 2010 reached 491.8 thousand tons, which was ranked first. Farmed tilapia absorbed the local and export markets. Tilapia is also the most fish produce new varieties. In addition, indigo can be cultivated in various aquatic environments and Nila container can be cultivated in freshwater, brackish, and sea, and all containers can be used for the cultivation of indigo cultivation.

Fish as food health and pharmacy

ruliyandi@gmail.com (ruliyandi) — Sun, 5 Apr 2015 01:12:00 +0700

Fish as Food Health and Pharmacy. The notion that fish and aquatic biota important role in health and human intelligence has been proven by experts. In the last 25 years a lot of scientific discoveries from the world of nutrition and health experts who prove that fish and other seafood species is very good for health and human intelligence (Fridman, 1998 in Dahuri, 2003). In fact due to seafood containing an average of 20% digestible protein with essential amino acid composition is balanced. Fish also contains omega-3 which is very important for the development of brain tissue and prevent heart disease, stroke, and high blood pressure. Experts prove that omega-3 fatty acids play an important role in the growth process of nerve cells, including brain cells, so as to improve intelligence, especially in children who are undergoing a process of growth and development. Deficiencies in eating foods that contain omega-3 resulted in a number of mental disorders: depression, poor memory, low intelligence, weakness learning, dyslexia, can not pay attention (attention deficit disorder), schizophrenia, dementia, Alzheimer's disease, a degenerative neurological disease, multiple sclerosis, alcoholism, outlook weak, lack of concentration, aggression, violence, and suicide. Approximately 70% of the human brain is made up of proteins and fats, including cholesterol. Therefore, the brain needs protein and fat to grow and function optimally. Cholesterol is necessary for the body, especially for children and adolescents, for the formation of the brain, hormones, repair damaged tissue, growth, build muscle, and so on.

utilization of freshwater fish consumption. (Food ingredients)

utilization of freshwater fish consumption.
1. foodstuffs
2. The health food and pharmaceutical
3. industrial raw materials
4. ornamental fish
5. The science and technology

1. Food Ingredients. fish and aquatic biota (water) is generally a highly nutritious food and have exploited mankind since humans began hunting. Humans who live around rivers, lakes, and marine capture and picked up a variety of aquatic biota to eaten raw or cooked. Initially, the fish is only used as a side dish. For residents as its main food ingredients rich in carbohydrates such as rice, corn, bananas, cassava, sago, and the other, the only fish in the complement every meal. Even in certain communities, fish consumed only at certain times. While still a child, the author often hear the words "do not eat a lot of fish, worms later." The words spoken by the parents to their children because of their ignorance about the nutritional value of fish. Therefore, the level of fish consumption of Indonesian society is still very low, only about 30 kg / capita / year. Compare with Japan and the Maldives where people eat fish at 140 kg / capita / year and 153 kg / capita / year. fish and aquatic biota is a highly nutritious food. Fish and aquatic biota contains proteins, fats, vitamins, carbohydrates, selenium, calcium, and magnesium. Average fish and aquatic biota contains 20% protein and omega-3 fats that are beneficial to human health. Therefore, in many societies of the world, the consumption of fish is not just a complement or a side dish, but is a major food ingredient. Fish are no longer just for help filling, but beneficial to human health.

PROSPECTS OF FISH FARMING IN FRESH WATER CONSUMPTION.

ruliyandi@gmail.com (ruliyandi) — Fri, 3 Apr 2015 22:45:00 +0700

PROSPECTS OF FISH FARMING IN FRESH WATER CONSUMPTION.
In 2011, Indonesia produced about 10.4 million tons of fish consisting of production of 5.1 million tonnes capture fisheries and aquaculture or aquaculture amounted to 5.3 million tons. Capture fisheries production of 5.1 million tonnes has already reached the optimum point or solid catch (full fishing) that it can not be improved anymore. Capture fisheries production of 5.1 million tons are already approaching the limits of international commitments regarding the production of fishing is only allowed to reach 80%. Indonesia's fishery potential, particularly marine fisheries, amounting to 6.4 million tons in the sustainable potential. With production of 5.1 million tonnes mean capture fisheries production has reached 79.6%. While international commitments in CCRF (Code of Conduct for Responsible Fisheries) arranged for fishing does not exceed 80% of the sustainable potential.

In general water or fresh water, capture fisheries sustainable potential of about 0.9 million tons / year. In 2010, fisheries production in public waters around 0.6 million tonnes or 66.6% have achieved sustainable potential. That means remaining open water fishery potential of 13.4% or 120,000 tons of fish that can be caught. But this figure is contrary to the facts on the ground that the fishery in public waters can not enhanced anymore because it has experienced solid catch. Thus, it can be said that the national fisheries production has reached the optimum. Production can not be increased further, especially the areas that have been overfished and overfishing is full. in the coming years, fisheries production is expected stable or even decreased. Production can be increased through aquaculture fisheries or aquaculture. Potential Indonesian aquaculture production reached 57.7 million tons, with details of 47 million tons of mariculture or mariculture (marine aquacuture), 5 million tons of aquaculture (Brackishwater aquaculture), and 5.7 million tonnes of freshwater aquaculture (freshwater aquaculture)

Sea water aquarium

Sea Water Aquarium. As we move past the deadline and brackish water aquarium, we get into shape really seawater. When we go over that, a whole new world opens, fish and invertebrates. has a stunning color that we often hold my breath. Most of these creatures come from the coral reef environment, and as well we admit it or not, we are all captivated by the beautiful underwater scenery of the tropics, it is not surprising, and completely understandable, that so many new aquarium owners fell in love with the concept has a miniature coral reef with all its glory. However, before plunging straight practice. there are some important questions that need to be considered. For example, coral animals and plants derived from one of the most stable habitats known to man, and creatures that have evolved over the long term so as to adjust. There are three main types of marine aquarium. 1. aquarium fish only, consists of a selection of fish species that can live together in harmony. 2. aquarium invertebrates, solely consisting of invertebrate and plant communities. 3. aquarium mix, consisting of fish, plants, and invertebrates are well chosen.

Management of fish feed

ruliyandi@gmail.com (ruliyandi) — Sun, 29 Mar 2015 13:47:00 +0700

Management of fish feed. In aquaculture, feed is an important component that requires a lot of costs for procurement. Feed directly influence the growth rate of farmed fish 1. Fish Food Nutrition. Quality feed nutritionally complete and balanced. Fish feed must contain protein, fat, carbohydrates, vitamins, and minerals in sufficient quantities and qualify the needs of fish. a. Protein. Proteins are complex organic compounds are composed of many amino acid protein can be derived from plants and animals. Proteins of vegetable plants are usually more difficult to digest fish because wrapped cellulose. The content of amino acids in vegetable protein is less complete so need to be supplemented with animal protein. Protein is the most important element in the feed. The main function of protein for fish metabolism is acting as a network builder body, replacing damaged tissue, plays a role in reproduction, the main constituent component of enzymes and hormones, and plays a role in metabolic processes in the body of the fish. Group of carnivorous fish requires a larger protein than fish herbivores and omnivores. The optimum protein content of fish feed is 25-35% . Fat serves as a source of energy. In feed formulation, fatty fish can help buoyancy at the surface of the water. Fat content in a good feed is 4-16%. Excessive fat in food is not good for the health of fish as food becomes easily oxidized so that the smell became unwell. Carbohydrates. Carbohydrate into energy source for fish, can be used directly into energy. Materials containing carbohydrates such as corn, bran, tapioca and sago. carbohydrate fish needs to be influenced by the type of fish. herbivorous fish such as carp, Tawes, Nilem need carbohydrates greater than omnivore and carnivore. Fish herbivores have carbohydrate digestibility higher. Needs carbohydrates to feed herbivorous fish is between 30-40%, 25-35% omnivores, and carnivores 15-20% Vitamin. Vitamins are essential compounds that can only be filled from outside the fish, and is required in small amounts. Vitamins can be added to the diet because the body can not produce fish. Fish that eat all the nutrients, including vitamins from natural foods. Mineral.Mineral fish needed in small amounts but very dizzy. Minerals function in the metabolism and tissue formation. Minerals are divided into two, namely makromineral such as calcium (Ca), sulfur (S) Phosphorous (P), Chloride (Cl) natrum (Na), potassium (K), and Magesium (Mg), while mikromineral is zinc (zn), Manganese (Mn), copper (Cu), molybdenum (Mo), chromium (Cr), Fluorine (F), and lodium (l). Mineral Fe, Cu, and Cr. play a role in respiratory function while minera Ca, P, F and Mg plays a role in the function of the formation of bones, teeth and scales.

Fish pond embankment

ruliyandi@gmail.com (ruliyandi) — Sun, 29 Mar 2015 07:56:00 +0700

fish pond embankment. Calm water fish pond has many important components, such as a fish pond dike. Fish pond dike made with a trapezoidal shape is wider bottom. This meant that not prone to landslides. The slope of the embankment should be no more than 45, to make the pond needs to be done hoeing the middle, move the soil to the edge, forming dikes. To prevent landslides embankment cliff, cliffs can be planted with grass (Cynodon dactilon). rearing pond depth is 100-150 cm. The water level of the bottom of the pool can be set from a height of 50-120 cm, depending on seed size and stocking density. When the fish have started great with a dense population, the water level can be expanded up to 120 cm.

Seeds of fish to be stocked and cultivated in ponds, floating net cages and cages should be checked beforehand health.

ruliyandi@gmail.com (ruliyandi) — Sat, 28 Mar 2015 23:08:00 +0700

Seeds of fish to be stocked and cultivated in ponds, floating net cages and cages should be checked beforehand health.

In the selection of fish to be stocked seeds should be healthy and have the same size so that growth can be together until the harvest.

Some criteria for healthy fish seed is as follows:
A. Having the same size and brightly colored
B. when the fish move in the water, the fish must be agile and nimble
C. The fish should be healthy and free from germs
D. fish seed should be complete no defects and injuries due to transport or pathogen infection.
E. The position of the body in the normal water
F. If the water in the container is rotated, fish will be swimming against the tide turns.
