Assignment task:
In response to two of your peers provide additional feedback about how that technology or advancement could be applied to another species of crustacean. For example, many of the advancements have centered around shrimp farming, but could be broadly applied to other species of crustaceans including ornamental species that are in the aquarium trade. For example, one of the advancements in shrimp farming is pathogen free broodstock. Would this apply to other decapod crustaceans? Why or why not? What other issues might that species be facing for advancement in their culture system?

Biofloc technology is a technology that is used to reduce the reliance on fishmeal in the world of aquaculture by using microbial communities to process waste from the creatures in the system into biofloc which is then used as feed. The tech removes organic nitrogen, improves water quality, and creates microbial proteins which are then used as a feed supplement in aquaculture. Biofloc can help to improve the growth quality of creatures that are being raised in a system as well.
The article that I found relating this to shrimp aquaculture is entitled "Application of Biofloc technology in shrimp aquaculture: A review on current practices, challenges, and future perspectives". This article covers how it's possible to combat the large environmental impact that shrimp farming has had previously by being its own self-sustaining system. This is created by using microbial communities that shift waste from the shrimp into biofloc that is then used as a food source for the shrimp. There has also been data that has shown that, with this water system being a closed system, there is a significantly lower risk for disease as there is less chance for contamination.

For this discussion I chose to focus on pathogen free seed in shrimp aquaculture. Disease runs rampant in crustacean aquaculture due to over stocking, poor water quality and the introduction of different pathogens when translocating. This means that to fight this problem it needs to start at the source. For crustacean aquaculture the process is started with seeding an area or introducing young live crustaceans into the aquaculture system. These crustaceans may not all come from the same source and can be combined with other crustaceans later in the process. This can create a bridge for pathogens to run rampant in these systems. "The greatest threat to the future of world shrimp aquaculture is disease, in particular the virulent untreatable viruses, infectious hypodermal and haematopoietic necrosis virus (IHHNV), taura syndrome virus (TSV), yellow head virus (YHV), and white spot syndrome virus (WSSV). " (Lotz, 1997). These diseases still run rampant in todays aquaculture systems. It is suggested that 55% of shrimp that is consumed annually is farmed, and that we are losing most of the yield to disease and over stocking. With using new techniques to stop the spread of these diseases such as pathogen free seeding this will help avoid these diseases and allow for a more sustainable practice over all!
