Government-funded scientists genetically developed a more robust and resilient kind of farmed shrimp, IVN-1, by crossbreeding Indonesian shrimp with US broodstock. The new disease-resistant breed grows faster and is better adjusted to the local climate, which makes for cheaper cultivation of the stock.
“[IVN-I] is highly resistant to shrimp disease and can be harvested faster for a more affordable price,” said Made L. Nurdjana, the ministry’s director general of aquaculture, the Jakarta Globe reports.
Already last week, two facilities in Situbondo and Karangasem in Bali were producing IVN-1 shrimp for distribution to farmers throughout the country. Shrimp farmers will be able to purchase the product at the low price of IDR 50,000 - IDR 75,000 (USD 4.90 - USD 7.34) - just 16-18 per cent of the US broodstock cost, according to Nurdjana.
“The more affordable the broodstock is, the less farmers have to pay to buy shrimp fry,” he said. “By using new varieties, for example, farmers will only have to pay IDR 15 (USD 0.0015) per shrimp fry. This can reduce production costs.”
Shrimp farms in Indonesia need a vannamei broodstock of 900,000 - 965,000 annually and, thus far, the country cannot meet this amount on its own. Consequently, it must expensively import 320,000 vannamei parents, mostly originating from the US, to complement its national production of 643,000.
US broodstock from the State of Florida costs Indonesian farmers IDR 300,000 - IDR 400,000 (USD 29.37 - USD 39.16) per pair, which is equivalent to IDR 35 (USD 0.0034) per fry. Each pair of broodstock, when of the highest quality, can spawn 700,000 fry.
The new type of shrimp takes three and half months to grow to harvest size as opposed to the Florida shrimp’s four-month period, which translates into handsome savings for Indonesian farmers, in that IVN-1 is also resistant to disease.
“This could push smaller breeders to develop new varieties and reduce national dependency on bigger companies,” said Iwan Sutanto, chairman of the Indonesian Shrimp Club.
The shrimp cultivation industry is highly important in Indonesia, a business worth USD 2.3 billion in exports, 30 per cent, or USD 690.3 million, of which are directed to the US market.
