Asked a question last year

Dear Sirs, I have observed that many L. vannamei shrimp farmers in AP (India) where the culture is done in low saline waters using ground ( bore) water, salinity range 5-6 ppt use lot of commercial grade minerals like Zinc Sulphate 60%, Mutate of Potash 33%, Magnesium Chloride and other fertilizers to enrich the soil with minerals. The bore water has 200 ppm of Calcium, 100 ppm of Magnesium but the Potassium levels are pathetically low 20-30 ppm. Does the enrichment of soil really helps in due course of culture where the farmers believe that the soil slowly releases the minerals in water and maintain required level in water? Kindly suggest good pond preparation methods to be adopted for low salinity culture and key minerals to be checked during the crop and quantities to be applied e.g in a 0.5 ha pond.

The New Shrimp List is created to replace the Yahoo group shrimp list that has been deprecated by Yahoo. This new site will allow anyone interested in the shrimp industry to post, question, search, blog, etc. etc. the new site offers much more flexibility and in time should serve as an extensive knowledge base for anyone who wants to learn more about the shrimp industry.

According to Murray and Eltholth (2018) the pond culture of Penaeus vannamei in Andhra Pradesh is practiced from freshwater (0 salinity) to brackishwater (up to 30 ppt)… however, the average salinity for culturing P. vannamei in Andhra Pradesh is 10 ppt. (See slide # 20)

Adjustment of pond salinity is by mixing from different water source as reported by Murray (2018) e.g. ground water (borehole) and surface water (canal, river, tidal creek, coastal seawater). (See slide # 5)

With regards to shrimp farm size, small-scale shrimp farming is the most common in Andhra Pradesh according to Srinivas et al. (2016). (See Page 82, Nursery, Culture, and Feeding Practices, 3rd Paragraph, 2nd Sentence)
