fish gurami

The gurami was the original fish Indonesian waters that have spread to the South-East Asian territory and China. Was one of the fish labirinth and in a manner taxonomy including the family Osphronemidae. The gurami was one of the commodities that often was developed by the farmers this was caused by the quite high market request, the maintenance was easy as well as the relatively stable price. morphology, this fish had the single lateral line, complete and was not interrupted, scaly stenoid as well as had teeth to the lower jaw. Tail fins became round. First weak fingers stomach fins were the long thread that functioned as the tentacle. High the body 2.0-2.1 times from long the standard. To the young fish was gotten erect lines were black totalled 8 up to 10 and to the area of the tail starting point was gotten by the black point bulat. n the gurami was the original fish Indonesian waters that have been one of the fish labirinth and in a manner taxonomy including the family Osphronemidae. The gurami was one of the commodities that often was developed by the farmers this was caused by the quite high market request, the maintenance was easy as well as the relatively stable price. he gurami could spawn year round, although his productivity was higher especially in the dry season. As for the matter that must be paid attention to for this spawning was solid tebar the mother, the layout of the nest, the egg harvest and the quality of water of the spawning media. Female was characterised from the form of the head and the jaw as well as the existence of the black spot to the fins sheath. The male mother was marked by the existence of the bump in the upper division head, the lower jaw that was thick especially at the time of the spawning season and the nonexistence of the black spot to the sheath of chest fins. Whereas the female mother was marked by the form of the upper division head flat, the thin lower jaw and the existence of the black spot to the sheath of chest fins. solid tebar the mother was 1 ekor/5 m2 with the number comparison jantan:betina was 1:3-4. The dispersion of the mother could be in the spawning pond carried out in a teamed manner (in accordance with the comparison) to the pond that disekat or communally (one pond was filled up by several couples). The female mother could produce the egg 1 500 up to 2 500 the item/kg the mother. The nest was placed 1-2 m. from the place of the nest material with the depth 10 -15 cm from the surface of water. The nest was installed was level in line with the surface of water and appeared to the side of the place of the nest material. The place of the nest material was placed in the surface of water could take the form of the rough cane work from bamboo or the material other was arranged in such a way as the mother of the fish found it easy to take the coconut husk/palm fibre to make the nest. The production of the nest could take place while 1 up to 2 weeks depended on the condition for the mother and lingkungannya.a. The nest inspection that has contained the egg could be carried out by means of feeling and shaking the nest slowly or penetratingly the nest used lidi/the wire and shook him. The nest that has contained the egg was marked by the issuing of oil/the egg from the nest to the surface of water. The nest that has contained the egg was lifted. The egg was separated from the nest by means of opening the nest in a careful manner. Because of containing oil, the egg will float in the surface of water. The good egg was yellow clear whereas the egg was yellow turbid was separated and thrown away because of the egg like this will not hatch. Oil that emerged could be reduced by means of being absorbed used clotThe quality of the good spawning media was the temperature 25-30 oC, thought the pH 6.5 - 8.0, the rate of the change in water 10-15 % per the day and the height of pond water 40 - 60 cm. Solid tebar the egg 4 up to 5 butir/cm2 with the height of water 15 - 20 cm. The density was counted per the area unit of the surface of the forum in accordance with the characteristics of the vague egg. To maintain the content of most protracted oxygen, in the hatching media must be added by small aeration but must be guarded so that the egg is not stirred. The quality of good water of the hatching media was the temperature 29 - 30 oC, thought the pH 6.7 - 8.6 and originated in the ground water. When source water contained high carbon dioxide, thought the low pH or contained the metal material (for example the iron), better water was bent first for 24 hours. The egg will hatch after 36 - 48 hours. After the egg hatched, the larva could continue to be maintained in a funnel for the hatching/the wash-basin until the age 6 days were afterwards moved to the aquarium. When the hatching was carried out in the aquarium, the transfer of the larva might not be carried out. For the maintenance of the larva, the replacement of water must be only carried out to throw oil away when oil that was produced when the hatching enough. Whereas when the larva has been given ate, the replacement of water could be matched with the condition for water that is when already many wastes from food and “ Faeces “. The maintenance of the larva was in the aquarium carried out densely tebar 15 - 20 tails/litre. Food began to be given at the time of the larva be aged 5 up to 6 days took the form of the Tubifex worm, Artemia, Moina or Daphnia that was matched with the aperture of the fish mouth. The quality of water better be maintained in the level of the temperature 29 - 30 o C, thought the pH 6.5 - 8.0 and the height of water 15 - 20 cm.Telur will hatch after 36 - 48 hours. The maintenance of the seed in pendederan I could be up to V done in the aquarium or the pond. In the aquarium was done same as in the case of pemelihaaran the larva but must be done by the thinning out. Whereas in the pond must be carried out by the preparations activity for the pond that covered the processing of the basic land of the pond, drainage, plastering, fertilising, the water filling and pengkondisian pond water. The processing of the basic land of the pond could take the form of the hijacking, peneplokan and the improvement of the pond dyke. Drainage was carried out for 2 - 5 days (depended the weather).
When being determined the fish was attacked by the medical treatment parasite could be carried out with giving of salt 500 - 1000 mg/l by means of the submersion for 24 hours. Whereas when was determined was attacked by the medical treatment bacteria could be carried out with giving oksitetrasiklin with the dose 5 -10 mg/l in a manner the submersion for 24 hours. Generally the gurami cultivation was still being carried out by the community with intensive technology. Really pemeliharaa him was relatively old so as to be carried out in several maintenance stages that is the germination stage, the stage pendederan and the enlargement stage, where in respectively the stage produced the product that could in marketed alone. The gurami market relied on the domestic request. Nevertheless his business prospect was promising enough to remember the request from the quite big community. The gurami was more enjoyed was sold in the living situation or fresh, and usually his price was also more expensive in the living situation. In the meantime, was not yet received by information concerning diversification of the whim product from this fish except in the form of fillet. The role of the Ikan Greenhouse was in the development of the gurami carried out including taking the form of the provisions of the mother and the prime seed and the introduction to cultivation technology intensively to pembudidaya the fish. Nevertheless, the step in the further development that still must be wrought on was the aspect of the good marketing in the domestic market and the export.
The territory survey for efforts pendederan the gurami was one of the areas of fish centres guramie in Central Java that is the Banyumas Regency. Whereas the territory survey for the enlargement of the fish was the Bogor Regency. Therefore technical information pendederan and the enlargement of the gurami especially used information that was received from the condition for the businessman and the other agency in the two territories. The calculation assumption of cultivation finance pendederan the gurami in this research was to use the fish seed that came from the germination activity by pembudidaya other seriously early 1 gram and was increased to reached heavy 20-25 gram (the pattern 1). Whereas the calculation assumption of finance in the enlargement cultivation used the seed would that came from pendederan by pembudidaya other seriously early 200-250 gram that was increased until achieving the measurement of consumption (the pattern 2) .
