Guidelines for Successful Marine Shrimp Farming

Introduction The provincial sub-department of Fisheries has advised marine shrimp farmers to speed up their seeding in accordance with the actual situation of growing ponds to achieve an abundant crop of brackish water this year. In order to achieve this, farmers must pay attention to various matters before stocking. Matters to Consider Before Stocking One of the key things to consider before stocking is the degree of salinity, which should be at 10-15‰. Additionally, traceable post larvae, suitable stocking density (60-80 pcs/m2 for white leg shrimp with PL≥12mm and 20-25 pcs/m2 for black tiger shrimp with PL≥15mm), and frequent monitoring of weather and environmental survey results should also be taken into account. Another important factor is the technical process from pond rehabilitation to water treatment and post larvae selection. It is essential to pay attention to every detail of the process to ensure the best possible outcome. Post Larvae Nursing and Farming Households with good conditions are advised to nurse post larvae in small ponds, inland ponds or pond liners at a density of 1,000 pcs/m2 within 25 or 30 days before stocking in growing ponds. This helps save time, decrease disease outbreak, and reduce production costs. Marine shrimp farmers are encouraged to apply science and technology in production with models such as multiple stage practice, round ponds, floating ponds, and pond liners. These models help reduce disease outbreaks and harvest bigger size shrimp (20-25 pcs/kg) for higher economic efficiency. Conclusion In conclusion, marine shrimp farming requires a great deal of attention to detail and various factors such as salinity, post larvae, and stocking density must be considered before seeding. By following the recommended technical process and utilizing science and technology in production, farmers can achieve a successful harvest and higher economic efficiency.

Pangasius Exports Down 39% in the First Five Months of 2020

Vietnam’s pangasius exports in the first five months of 2020 amounted to $456 million, a 39% decrease from the previous year. This decline was primarily due to the impact of the COVID-19 pandemic on Vietnam’s seafood export volume to core markets, such as China, EU, and the US. Full Recovery Expected in Quarter III of 2020 According to the Ministry of Agriculture and Rural Development, the pangasius sector is forecasted to recover fully in quarter III of 2020. However, the swift slump has made pangasius exporting companies that depend on those markets face multiple difficulties, which have directly impacted pangasius material production. Sales to Core Markets Decline Sales to China, EU, and the US saw a double-digit decrease compared to the same period last year. The demand for pangasius material has also been quite low, as most large companies refuse to buy pangasius from outsiders but buy fish from contracted farmers. Impact on Prices The drop in demand has kept prices of pangasius material in the Mekong Delta low for the last few months. After the April 30-May 01 holidays, prices that companies offer and their purchases remained as before, ranging between 18,000 and 18,200 dong/kg (pangasius type I size 700-900g/pc). Efforts to Improve Quality To achieve the growth of the pangasius sector as soon as possible, the sector will pay strict attention to control aquaculture conditions and quality of materials. The Directorate of Fisheries plans to grant/re-grant identification codes to fish farms in accordance with the Fisheries Law. Participation in a Production Chain Farmers and processing companies need to participate in a production chain. An electronic traceability system is built in the export chain from processing companies to farming facilities and growing farms that are already granted identification codes for information transparency assurance. Improving Quality of Broodstock The General Director of the Directorate of Fisheries, Trần Đình Luân, said that pangasius, which is able to grow and develop in salty water, must be selected to enhance the quality of broodstock. Conclusion In summary, the pangasius sector in Vietnam has been severely impacted by the COVID-19 pandemic, with a 39% decline in exports in the first five months of 2020. However, the sector is expected to recover fully in quarter III of 2020. To achieve this, the sector needs to improve the quality of materials and control aquaculture conditions. An electronic traceability system has been put in place to ensure transparency, and farmers and processing companies need to participate in a production chain. The quality of broodstock also needs to be enhanced to improve the pangasius sector’s overall growth.

Shrimp Prices Expected to Rise in Q3 Due to Short Supply of Shrimp Material

Shrimp farmers have been facing challenges with the supply of shrimp material since May, resulting in a decline in shrimp prices. The prolonged summer heat, salt intrusion, and the coronavirus pandemic have led to a fall in shrimp consumption, causing slow seeding and a decrease in prices. However, companies and authorities have forecasted an increase in shrimp prices from quarter III. Supply and Demand of Shrimp Material Despite forecasts of a short supply of shrimp material in May, the source of shrimp material has met the demand of processing and exporting, causing prices to fall. Even though the stocking of shrimp is later than in previous years, most of the stocking area is extensive or super-extensive white leg shrimp, which applies high technology. Therefore, the shrimp output in the first four months of 2020 only slightly decreased from the previous year. Early Harvest and Partial Harvest One reason for the sufficient supply of shrimp material in May is the changing weather, which resulted in an early harvest with a large number of small-sized shrimps. However, factories were struggling with deficient workers, leading to a decrease in processing capacity. In some areas suffering from salt intrusion and short supply of water, farmers had to carry out partial harvest or early harvest to decrease the stocking density. For instance, partial harvest was carried out in the farming area owned by the Xuân Phú shrimp cultivation business of Sao Ta Food JSC due to a short supply of water. The director of the business, Ngô Văn Nghiệp, stated that “we had to carry out partial harvest due to the high survival rate of shrimp. We get around 40-50 tons of shrimp size 50-60 pcs/kg in the fear of deficient water to maintain the same stocking density.” Decrease in Prices of Shrimp While small-sized shrimps are abundant, factories are struggling with deficient workers, causing a decrease in processing capacity. As the consumption of shrimp in major markets has not recovered, prices of shrimp in the Mekong Delta fell in May but increased as forecasted, making shrimp farmers surprised and disillusioned. Prices of shrimp, especially white leg shrimps, decreased compared to early May. However, farmers can still earn a good profit if they reach the target output. With the current price of 105,000 dong/kg for white leg shrimp size 70 pcs/kg, farmers can earn 30,000-35,000 dong/kg if they reach the target output. As for gig-sized white leg shrimps alone, if the target output is reached, and FCR is reasonable, farmers can earn 70-80%. Expected Rise in Shrimp Prices Despite the disillusion in shrimp prices, the speed of stocking in most farming areas in Sóc Trăng and the Mekong Delta is increasing. As usual, shrimp prices rise back from September and October when companies start their purchases to fulfill orders placed on holidays and Tet, from the end of the year until early next year. According to companies, prices of shrimp may sustain well in early quarter III, one month earlier than the previous two years. This is forecasted upon the little stockpiles in the EU, US, and Japan. The powerhouses such as China, India, Ecuador, Indonesia, and Thailand are suffering from challenges due to the coronavirus outbreak and weather, resulting in a forecast of at least a 20% decrease in shrimp supply. It means that supply, which is lower than demand, is highly possible. Thus, shrimp prices are expected to be better from early quarter III.
