In order to increase productivity, the farmers need to ensure the supply of raw shrimp is clean, safe, sustainable, and many shrimp farms around the world are adopting the new farming technology, the most advanced.
To create large shrimp produce on 1 unit area, Dr. L.Lawrence, (Agricultural Research Station Texas, USA) has the idea of super-intensive shrimp farming systems stacked water. The system allows production to be 453,000 kg / 0.4 ha of water surface, higher than shrimp farming systems in natural ponds as well as production systems previously closed circulation. Dr. L.Lawrence have researched and concluded that it would be effective if it can help relieve the farming system. All that his research has focused reduced water depth. After 4-5 years of research, he came up with the appropriate depth of the water level of the aquarium is 15-20 cm and can be classified into 7 overlap, all shrimp systems are controlled by computers. In 2012, aquaculture production company bought the rights Royal caridea license this culture systems worldwide and building system technology shrimp in a new facility. Predicting the future, every major urban areas will have a similar shrimp farm technologies.
Shrimp 3-phase process of Grupo Granjas Marinas company, Honduras was confirmed sustainability, biosafety, highly productive, and more importantly, is not used artificial food. In Phase 1, the Company adopted rotifer species biomass density of 80 units / ml and copepod density of 16 units / ml in the system under the green water Raceway. Then zooplankton biomass move down phase 2, where nurseries layout and shrimp feed. Copepod biomass could reach about 544 kg / ha in 7 days and rotifer biomass can reach 2270 kg / ha in 4 days. In Phase 2, the shrimp are raised in nurseries closed system can accommodate up to 1,200 tons. When seed size reaches 4 to 4.2 g / head, switch to the grow-in phase 3 closed with a density of 8.1 fish / m2, using the floc particles and plankton for food. The average growth rate of 1.4 g / week, yields 912 kg / ha, the average survival rate of 74%; of the 350 hectares of shrimp ponds and the average weight of 15-16 g / head, while raising 8 weeks. For 3-phase feeding technology, nursery ponds are located in a central location, making transporting large shrimp to grow-out ponds more favorable, may be extended run time, seed sized bigger and unstressed during transport. At the same time natural food rich in nutrients, easily absorbed shrimp; the same culture environment ensures clean shrimp facilitate good growth. 2015, the company has built more 700 hectares, bringing the total shrimp farming area 3-phase technology to 1,100 hectares.
Water treatment technology, control Vibrio parahaemolyticus causes premature death syndrome (EMS), acute pancreatic necrosis liver (AHPND) of the Company Silver Bulle, Mexico has confirmed the effectiveness and granted patents. This company has created a new type of device capable of sterilization by means of H2O2 to maintain lasting bactericidal activity, is highly effective in protecting the environment and health of farmed shrimp. Dr. Silvia Gomez Government Laboratory in Hermosillo, Mexico have tested shrimp in water with Vibrio parahaemolyticus density of 105 / ml, using equipment Silver Bulle. As a result, the growth of shrimp, well developed and there are no signs of infection die sooner or pancreas and liver necrosis reached above 90% survival rate. According to Silvia Gomez, water treatment systems in the ponds of Silver Bullet can control the level of development of Vibrio parahaemolyticus, is not harmful to shrimp, easy adjustment to help the fight against dangerous diseases that killed two early pancreatic and hepatic necrosis very effective.
