Lobster Farming RAS

Lobsters are invertebrates with a hard protective exoskeleton. Like most arthropods, lobsters must moult to grow, which leaves them vulnerable. During the moulting process, several species change colour. Lobsters have 10 walking legs; the front three pairs bear claws, the first of which are larger than the others. Although lobsters are largely bilaterally symmetrical like most other arthropods, some genera possess unequal, specialised claws.

Lobsters of the family Nephropidae are similar in overall form to a number of other related groups. They differ from freshwater crayfish in lacking the joint between the last two segments of the thorax, and they differ from the reef lobsters of the family Enoplometopidae in having full claws on the first three pairs of legs, rather than just one.

Lobsters are omnivores and typically eat live prey such as fish, mollusks, other crustaceans, worms, and some plant life. In general, lobsters are 25–50 cm (10–20 in) long, and move by slowly walking on the sea floor. 

RAS Recirculating aquaculture system 

Recirculating Aquaculture System (RAS) series of treatment processes is utilized to maintain water quality in intensive fish farming operations. These steps of Recirculating Aquaculture System (RAS) are often done in order or sometimes in tandem. 
After leaving the vessel holding fish the water is first treated for solids before entering a biofilter to convert ammonia, next degassing and oxygenation occur, often followed by heating/cooling and sterilization. Each of these processes can be completed by using a variety of different methods and equipment, but regardless all must take place to ensure a healthy environment that maximizes fish growth and health.
