understanding the difference betwen fish farms and fish ponds

Understanding the difference between fish farms and fish ponds Pond: In the form of land or a container made specifically for cultivating fish bounded by dikes or levees that is located on the beach or coast, source water comes from sea water or brackish water. Fish ponds: In the form of land or a container made specifically for cultivating fish bounded by dikes or levees are located on the mainland, the source of water is fresh water from lakes, reservoirs, rivers, irrigation canals, swamps or springs.

fish farming in small fields

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...

Criteria seed fish will be stocked

Seeds of fish to be stocked and cultivated in ponds, floating net cages and cages should be checked beforehand health. seed fish will be stocked to be healthy and fish seed should have a uniform size, so that a uniform growth of fish seed to harvest. Some criteria for healthy fish seed is as follows: A. Having a uniform 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

fecundity with age

fecundity with age. [At] some fish species, [relation/link] of fecundity with age [do] not be [is] same always in the meaning that that age there [is] which [do] not have an in with fecundity , there [is] which [is] its influence a few/little and there [is] also which [is] its influence by positip. Matter like that real correct if which [is] seen [it] only [relation/link] [among/between] fecundity with just age without seeing other parameter. variation [of] of Fekunditas that [is] individual very big, covering each;every influence of[is including also old age. Fish which for the first time [of] breeding ( spawners recruit) fecundity is not big like fish fecundity which have several times but its [is] same body weight. This matter as according to generelizability, that fish fecundity will increase during growth. big fish [of] its egg will be more many from [at] smaller fish. But this correlation there [is] its boundary where there will be degradation of that fish although amount gro...

PRINCIPLES OF POND FISH CULTURE

PRINCIPLES OF POND FISH CULTURE 1. Fish are dependent for food directly or indirectly on plants. 2. The weight of fish which can be produced in natural waters is dependent upon the ability of the water to raise the plants. We could increase production by adding plant organic matter produced elsewhere. 3. The ability of water to produce plants is dependent upon sunshine, temperature, CO2, Mineral from soil or rocks, nitrogen (NO3- and NH4-) , O2 and water. 4. The Natural fertility of the water is dependent on the fertility of the soil in pond bottom and watershed. 5. Fertlity of water can be increased by adding inorganic fertilizers. 6. After adding all essential minerals and all available nitrogen, the next limiting factor is CO2. This compound can be increased by adding organic matter followed by liming (Ca, Mg). 7. The next limiting factor in fish production, after mineral and CO2 are provided, is oxygen demand of all living and dead organisms in the water. This can be supplied by ru...

Brown algae Indonesia Able to Treat Tumors

Brown algae Indonesia Able to Treat Tumors More recently , Center for Research and Development Center for Product Processing and Biotechnology ( BBRP2B ) Research and Development of Marine and Fisheries ( Balitbang KP ) announces its latest research results . Species of brown algae Turbinaria decurrens ie living in Indonesia is considered capable of killing tumor cells of the cervix. Research that states that the algae or seaweed to treat cancer is not the first time . Previously , the red algae species Rhodymenia palmata and Ulva fasciata species of green algae are also reported to kill breast tumor cells . According to one researcher of such research, Nurrahmi , seaweed rich in compounds called flavonoids that have as an antitumor effect . He hopes to use algae research should be expanded . " Utilization of algae should not be limited to karigin sources , but could be the biological resour...
