FISH CULTURE

comet goldfish. fish comet is a kind of fish that have a variety of colors. This fish reared in ponds or tanks. pisciculture is generally carried out at the pool made of walls. These fish include fish omnivorous (eating everything).

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. 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.

fish farming in small fields land area of ​​fish farming is increasingly narrowed due to the many land conversion of agricultural land into land for housing, industry, commerce made limited land fish farming especially in urban areas, especially for the more limited scope for fish farming. While on the other hand increased food consumption needs, especially the needs of the animal protein required for maintenance and growth. From the above we need to make fish farming in small fields. One of the fish farming in small fields is the cultivation of the pool tarp. cultivation in the pool tarp has been done in various regions in Indonesia. generally for farmed fish in the pool tarp that is the type of fish that have a great tolerance towards the oxygen content in the water. some types of fish that have a high tolerance for the minimal amount of oxygen is catfish and carp. fish farming in ponds tarp does not take a broad space for pool tarp size generally is 3 m long and 2 meters w...

pedlery fish ponds pedlery fish ponds are usually made from the pool wall. this is because the pool walls stronger and more durable. The size of the fish ponds pedlery usually too big. which is about 2 x 1.5 m. For ponds that have no pedlery water source into the water pump is usually used as a means of circulation to keep the fish alive and fresh. Using water circulation pump serves to supply oxygen to the water in the pond. because the oxygen in the pond is relatively small due to the high density and lack of new water turnover. This pedlery pool made not just one but can be 5, 6, 7 or more depending on the needs. the large number of ponds is adjusted to the size and variety of fish species. so each pond is filled with one type of fish and with a certain size. http://hobiikan.blogspot.com/

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...
