Jakarta (ANTARA) \u2014 The National Research and Innovation Agency (BRIN)\nis developing a tubular tilapia egg incubator made from local materials\nto boost productivity more efficiently.<\/p>\n
\u201cThis incubator works to shorten the time female broodstock spend\nmouth-brooding their eggs. With this device, tilapia eggs can hatch in\nless than seven days. As a result, gonad maturation and subsequent\nspawning cycles in broodstock can be accelerated,\u201d said Mohamad Soleh, a\nresearcher at BRIN\u2019s Centre for Applied Zoological Research, in a\nstatement issued in Jakarta on Wednesday.<\/p>\n
Soleh explained that improving fry productivity is an important step\nin supporting the development of tilapia farming, which holds\nsignificant prospects. High demand for tilapia needs to be matched with\nincreased fry productivity.<\/p>\n
These reproductive characteristics form the basis for developing\nartificial hatching technology to improve seed production efficiency.\nAccording to Soleh, the advantages of the tubular incubator include its\ncapacity to hold eggs in large quantities, a high hatching rate, more\nuniform larval size, ease of harvesting, practical and efficient\noperation, and optimal management of hatching conditions.<\/p>\n
\u201cThe success of this egg incubation technology still depends on the\ndiligence of fish breeders. Accurate selection at the fertilised-egg\nstage \u2014 identifying eggs that have turned yellowish-brown \u2014 is one of\nthe main determining factors in achieving a high hatching rate. A high\nhatching rate and uniform larval size are the keys to boosting national\nfry productivity,\u201d Soleh said.<\/p>\n
He also highlighted the need to use all-male fry in aquaculture\noperations. The use of male fry is expected to increase farming output\nand yield greater profits.<\/p>\n
Male fry are produced through periodic high-temperature treatment\n(thermal shock) starting from newly hatched larvae until the stage when\nlarvae begin swimming freely, followed by rearing the fry until they\nreach a size ready for stocking in aquaculture ponds.<\/p>\n
Soleh noted that tilapia farming is supported by vast available\nfarmland, well-established cultivation technology, easily obtainable\nfry, and the fish\u2019s ability to adapt to fluctuations in water\nquality.<\/p>\n
In addition, its harvest cycle is relatively short, at around four to\nsix months; it carries low to moderate business risk and is suitable for\ndevelopment on scales ranging from smallholdings to industrial\noperations.<\/p>\n
\u201cTilapia farming is quite competitive compared with other fish\ncommodities such as gourami, common carp, tawes and nilem. The selling\nprice can reach Rp30,000 per kilogram, the market demand is open, and\nprofit can reach 20-40 per cent, making this a promising venture. Its\nrelatively short farming period also helps accelerate capital turnover,\u201d\nSoleh concluded.<\/p>", "url": "https:\/\/jawawa.id\/newsitem\/brin-develops-incubator-to-accelerate-tilapia-breeding-1784105807", "image": "" }, "sponsor": "Okusi Associates", "sponsor_url": "https:\/\/okusiassociates.com" }
