Cultivation of crayfish

Crayfish are found in all the continents of the earth, except in Africa and the Antarctic Continent. Species of crayfish have spread to certain countries, both developed and developing countries. This is done deliberately or unintentionally to replace the existing species with economic goals. (Brett 2006).

In Indonesia, many crayfish found a river in Papua. However, lobster, which comes from Papua is not all it can be caused by the original habitat that is relatively cold, so conditions are not suitable for hot areas such as the general areas in Indonesia.

The male sex

In crayfish, which mainly in pairs of male Cherax Quadriumumnya have red marks on the outside of both ends of capitnya. But the color red is not formed when capitnya still small. Generally, the size of 3 "or 7.5cm and have been seen.

That can create certainty is seen from his feet. Male sex is also visible bulge with a pair of legs on most tails. If only one so-called intersex.

Female genital

In the Red Claw lobster sex, there is no sign of red in the second capitnya. Female genital signs marked with the sphere in two to three feet from the well-calculated from the top and tail. Similarly, the male, female sex should also be a pair.

Shrimp in fresh water, could

Shrimp and vaname I can live in the range of salinity, which is very wide, between 0.5 ppt to 45 pptThe cultivation of shrimp and I vaname not only can be done in brackish water ponds. By applying the traditional system and semi-intensive cultivation of shrimp and I vaname can also be done in fresh water ponds. Ketut Sugama, Head of Fisheries Research Center Cultivation - the word means BRKP said, shrimp can live in the range of salinity, which is very wide, between 0.5 ppt to 45 ppt.
Simply can not, the cultivation of shrimp in fresh water has advantages, particularly to reduce the risk of shrimp have the disease caused by viruses and bacteria that many infeksi water salty waters. "One of the background is to reduce the risk of disease," said Achmad Sudradjat, researchers from the Center for Fisheries Research Cultivation.
With the background, I wonder if the development of shrimp cultivation in freshwater, it has done in many serious abroad, such as Thailand, the United States and several countries in the area of Latin America with the level of success that is quite satisfactory.
Sudradjat said, the actual cultivation of shrimp in fresh water with traditional systems also have been made by the farmers in Havant, Lampung and Polman-Sulbar. Farmers usually use a use a rice field cultivation of rice and milk together. The result is tantalize. From 1 hectare of rice field wide planted 10 thousand benur shrimp, I can produce 1.75 kuintal shrimp size 35, with a long 90 days of maintenance. Results are still added to 4 kuintal milkfish and 7 kuintal rice.
Unfortunately, not all of it is processed more serious by the government. Even the prospect of fresh water prawn cultivation is big enough, especially if you see the potential breadth ponds, freshwater ponds that is 2-3 km from the coast and the mouth termanfaatkan not optimal. "We (the party BRKP-red) have long been recommending it to the Directorate General of Fisheries aquaculture, but until now still not respon. Although only the traditional pattern, if this can be developed in a serious increase national production of shrimp, "Sudradjat supplement.

Shrimp fan

Shrimp fan, is a community of the coastal area. for the coastal area does not surprise fans again with the shrimp like this. in addition to good shrimp is eaten, perhaps he can cure the disease that does not stops urination. These shrimp live in salt water, coastal beaches and ponds, ponds in the waters salted water, long a fan shrimp is about 15cm to 20cm. unfortunately, shrimp, as this is not behavior in the fish market, other than thinking a little shrimp is not much meat to eat, and assume that is not strange to see the same / consummate,

FISH MUJAIR

BRIEF HISTORY

Fish mujair is consumption fish type of freshwater and saline, physique pipih pepper and saltly, black or brown. This fish comes from African water territory and first time in Indonesia found by father Mujair in river estuary Attacks south coast Blitar Jawa Timur in the year 1939. Fish mujair
has big tolerance to salt rate or salinit ace. This fish type has growth speed that is quicker relative, but after acceleration adult of its the growth will decline. Maximum overall length
reachable of fish mujair is 40 cm.

EEL CONDUCTING

BRIEF HISTORY

Eel is fish type consumed freshwater and briny with form of length integer body which only had its the dorsal fin and body smooth. Eel likes eats fish children which still small. Usually life in rice fields, in bogs and in multiplying small. In Indonesia since the year 1979, eel starts recognized and liked, the existing finite of eel many conducting and become one of export commodity.

Benefit from eel conducting is:
1) As supply of source of animal protein.
2) As accomplishment of basic necessities.
3) As blood adder drug.

LIME FOR FISH PONDS

Fishes In Europe and Asia, fish raisers have learned that the application of lime on fish ponds help a lot in the growth and reproduction of the fish therein, especially in water levels that have low calcium content. Like the application of fertilizer, lime is applied on the ponds. The most commonly available are those used on land—ground lime, and either calcite (CaCO3) or dolomite (CaMg (CO3)2).

As early as 1975, this has been studied in the Auburn University of Alabama (USA) on five fishponds that were treated with lime and five others not treated with lime but fertilized with ammonium nitrate and trisuperphosphate every two weeks. It was seen that plants growing in the ponds with lime flourished, and the fish increased by 25%. This was also tried in Malaysia as early as 1962 where the tilapia they raised in ponds increased by 10% with the application of lime.

Stop expansion to global shrimp fishpond Industries

WALHI’s Press Release

Jakarta, August, 31 2007- since the ownership of PT Dipasena Citra Darmaja switch to Central Proteinaprima International Holding (CP Prima) in the end of May 2007, rates of global fishpond fishery industry expansion on a big scale has been more rampant. This is a biggest threat for mangrove and ecosystem. Moreover, ADB (Asian Development Bank) have already approving US$ 33, 3 million loans to ‘promote’ fishpond fishery industry on big scale in Indonesia.

M. Riza Damanik, manager of coastal and sea campaign WALHI, as well as coordinator of ASIA (Asia Solidarity against Industrial Aquaculture) told, “within two decade currently, millions hectares of mangrove forest was being conversed as big scale fishpond of fishery industry. Ironically, besides giving negative impact to environment and society around, this mega project wasn’t aimed to local fishery product necessity fulfillment, but exported to countries, such as United States, China, and Japan.”

From ecological perspective, conversion of mangrove forest and ecosystem to shrimp fishery industry, causing: (1) destruction of mangrove forest ecosystem; (2) deflation quality of waterworks and fields, which was causing life quality descent of people around, begin from basic necessities (food and housing) to health; and (3) abrasion disaster occurrence, sedimentation, and saltworks groundwater around big scale-industrial shrimp fishery location.

1. Expansion of big scale-fishpond industry is certifying global imbalance. This is based on fulfillment fish demands partiality in development countries. Therefore, affectivity of global campaign STOP EXPANSION OF GLOBAL SHRIMP FISHPOND INDUSTRY for consumer, distributor, etc, in the world biggest consumer countries such as US, China, and Japan, become undoubtedly things.
2. Definitely, south-north consultation is much needed, as media information exchanges related to common enemy against big scale-fishpond industrial expansion.
3. Building trust between one and other to broaden political space, to fight for sustainability of global decision.
4. Driving collective understanding related to the real condition faced by global society, related to sustainability of living environment and food necessity fulfilment, either in local level, national, or regional.
5. Implementing collective goal to empower society’s basic rights (food and housing) fulfillment capacity.

In compliance with it, WALHI urges President Susilo Bambang Yudhoyono to keep pro-active on endeavor to stop rate of big scale- global fishpond industry expansion in Indonesia especially, and in global level, by campaigning STOP GLOBAL SHRIMP FISHPOND INDUSTRY EXPANSION.

In the end, the people waiting for their leader to work without reward and brave to enclosing a goal “create common welfare, not collective agony as nation. Not only ‘sale’ self image, but also nation image in global societies eyes, especially food sovereignty for all Indonesian people,” Riza Damanik said.
