Farallon’s “Megalarva” Making a Difference


In October 2015, Panama-based Farallon Aquaculture’s new operation in Phuket, Thailand, started supplying Penaeus vannamei nauplii, produced from pathogen resistant (GPR) and specific pathogen free (SPF) broodstock, to Thai shrimp farmers.  “Preliminary results show that these nauplii have a 65% survival rate on average at the hatcheries, which is a good result,” said Jose Bolivar Martinez, owner of Farallon.


Martinez said the postlarvae from the naups “haven’t had any epizootic event or any important mortalities so far, which is quite unique, because in Thailand during the past three years, shrimp farmers have expected to have an outbreak of diseases before they get to 60 days of growout.  ...We have ponds stocked with our genetics that exceeds 80 days and shrimp are healthy and growing at a good rate.”


“Since the outbreak of early mortality syndrome (EMS) in Thailand, farmers have been told to stock a fast growing PL so that they can harvest a commercial size (10 grams) before 60 days; therefore, they stock with fear, and are ready to have emergency harvests.”


“This has a psychological effect on the farmer which leads them to value growth above survival, as if all PLs are condemned to die before 60 days.  We have already proven in Thailand that our genetics gives the farmer the confidence to stock without fear, and with a higher growth rate than any local or imported SPF genetic.”


“Therefore, shrimp farmers are planning longer farming cycles, which implies that, at some point, Thailand will recover market for larger sizes, at least 22 grams, on the back of our nauplii supply.  It will take until the end of 2016 for the market to reflect the impact of the new genetics as more and more farmers decide to stock with Farallon genetics.”


So far, Farallon’s operation in Thailand, “Farathai”, is producing 20 million nauplii per day in its initial stage, and it plans to reach an output of up to 60 million per day by mid-2016 and 100 million per day by the end of 2016.  According to Martinez, Thai agribusiness giant Charoen Pokphand Foods has 50% of the seedstock market in Thailand, and Farathai is expected to have 10% of that market in 2016 and 25% in 2017.
