Minapoli, an aquaculture start up company, held a webinar session 2 on 22 March 2022 with theme is the role of genetics in supporting to increase national shrimp production. It held by collaboration between Indonesian Shrimp Forum (FUI) and the Indonesian Shrimp Breeder Communication Forum (FKPUI).
Mr. Agus Wibowoas general chairman of FUI said FUI supports the government’s program to increase shrimp exports around 250% (USD 4.25 billion) in 2024. To achieve this target, 15% export growth volume and 20% export value are required every year. However, in 2021 shrimp export growth only 10%. thereof it is necessary to improvement every stage shrimp culture, for example improve broodstock and shrimp fryquality to increase productivity of shrimp farming.
Agus Somamihardja as chairman of the Indonesian Shrimp Breeder Communication Forum (FKPUI) appreciated breeder get involved in holistic discussions. Development of geneticbroodstock shrimp research is not only about the phenotype, but is already in genomic so we can set genomic instruction to shrimp as we need. Further purpose in broodstock shrimp isnt only has fast growth but also has high survival rate during extreem condition such as disease resistance.
The speakers in this webinar come from two reputable shrimp breeding companies in Indonesia. The first speaker was delivered by Mr. Purnomo Hadi, country manager at PT SyAqua Indonesia. SyAqua Indonesia is a company with focus on genetic shrimp breeding, genetic development of broodstock, and feed for naupli (early shrimp). He said genetic improvement of shrimp is still concerned with high growth and survival rate. Since 2013, SyAqua had been research about resistance of shrimp in EMS/AHPND infected using selection method but unfortunatelyshrimp growth is not optimal. Therefore, it is trying to optimalize growth again.
He said that development in shrimp hatchery is not only about genetic performance of broodstock, phenotype or environmental interactions (feed, water quality) also have very important role in gene expression. Feed for broodstock in Indonesia commonly is marine worms (polichaeta)where caughted from nature so the nutritional content in it are inconsistent. This will have an impact on profimax (productivity of naupili produced per 100 female broodstock)in Indonesia is lower than other countries.
He also gave short trick about how to decide which one shrimp fry will have potencial high/ low growth before we order to buy. It simply thing we can do, to looking at the average daily growth (ADG). If the ADG value > 0.4 it can be said that fry shrimp has good growth. In addition, we can through a laboratory test approach to the DNA/RNA ratio. If the DNA ratio is higher it will suggested that the growth is slow.
The second speaker is Mr. Teddy Pietter, manager of BMC (Broodstock Multiplication Center) production at PT Kona Bay Indonesia. The broodstock product that launched from Kona Bay company is divided into three line namely speed line which has good growth with target market for good environment shrimp culture or at low disease zone category (green); strength line (good resistance against TSV, EMS, WSSV, and vibrio sp.) which has high disease zone in environment shrimp culture (red); and balanced line which has growth and good gains diseases) and this product is sold in Indonesia.
Mr Teddy Pietter also present about challenges in shrimp industry globally and how to prevent it. Important things that we have to learn to anticipate by control risk disease, social risk, and environmental risk management; increased efficiency; selling up shrimp to increase global shrimp consumption; and build trust between stakeholders in supply chain. The key to perform hatchery productivity are techniques in shrimp culture/ discipline used SOP, skill farmers, environment (natural conditions and disease status), and genetics of shrimp.
