Harvesting commercial adult shrimp species in aquaculture
Vannameis are more correctly called Whiteleg shrimp or Pacific white shrimp because of their transluscent white body. Scientists used to call it Litopenaeus vannamei (new scientific name). Vannameis are usually stocked in our ponds at the start of the cropping year after the ponds are cleaned up. Ponds where the vannameis are released have undergone the usual preliminary activities during pond preparation.
Vannameis for growing are usually purchased as post larvaes (usually PL-10 to 16). From hatching in a hatchery, it takes ahbout 25 days to produce a Pl-16. After 2 weeks, the vannameis are released into the ponds. Growing and Harvesting Vannamei Prawns/Shrimps in Ponds | Shrimp Farming Business...
The harvest of a shrimp pond is the final step of a long production cycle several months and is a most important one despite its short duration of a few hours. The entire harvest team must perform optimally for the best results in terms of shrimp yield and product quality. Both shrimp farmers and the packing plant have made significant investments to harvest products of the highest quality but often the implementation of inadequate planning or practices can negate the effort of several months of hard work and significant resources invested in just a few minutes. The most important factors to consider during a harvest are time and temperature but hygiene also has a very important role not only for food security reasons but also for the quality of the product itself.
Product quality can be interpreted in multiple ways depending on the markets and the different consumers and cultures. It is therefore very important to list and define with customers the various quality parameters in the most objective and comprehensive as possible. This list and the definitions of each parameter must be written and accepted by all parties to avoid misunderstandings that could have important commercial implications for all involved.
Even in countries where the local market does not seem overly concerned today with quality of the products be aware that consumer requirements in terms of quality are increasing rapidly in parallel with the rise of their living standards. This is a situation that can be observed in all developing countries for all the products of everyday life in general and for shrimp in particular. Shrimp producers must be ready to adapt their standards to this increase in product quality expectations by the market and must adapt their harvest procedures and personnel training accordingly.
