The research scope of this paper includes five stages: infrastructure construction of aquaculture farms, transportation of shrimp seedlings, shrimp breeding, shrimp transportation to market, and infrastructure disposal. Among them, feed production for shrimp breeding stage is a link, is the use of fish meal, soybeans, peanuts, fish oil, flour, minerals and adhesives production of compound feed When using this data set for Life Cycle Assessment, it is important to include all stages mentioned: infrastructure for farm construction, shrimp seedling transport, shrimp breeding, market transportation, and infrastructure disposal. Special attention should be given to the representative nature of the inputs and outputs from the aquaculture and feed processing factories, as well as the local water quality monitoring data. Ensure that the time and location of data collection are relevant for the assessed system and account for seasonal differences by considering the data from June and November 2019. If modeling transport to the market, use the provided transportation data from Rizhao City’s seafood wholesale market and aquaculture farm surveys.


Technology of factory culture of Penaeus alba. Factory farming is divided into three types: factory stillwater farming, factory running water farming and factory circulating water farming. The shrimp farmers in Rizhao City where this research institute is located mostly adopt factory running water farming. In this farming mode, farmers have a number of breeding sheds with brick-concrete structure, good light transmission and heat preservation. Each breeding shed will have a number of breeding ponds, the shape is mostly regular quadrilateral, the scale is mostly 4m(length)*4m (width), 5m(length)*5m (width), 6m(length)*6m (width), and the depth of the pool is mostly between 1m and 1.3m. The bottom of the pool is in the shape of a pot to drain water to the middle [110], and the center of the bottom of the pool is set with a Φ110 mm polyvinyl riser for drainage. Drainage is generally divided into three stages, the early displacement is small, about 8-10cm per day, the duration is mostly 25-35 days; In the middle period, the displacement is large, and the drainage is about 25-40cm per day, and the duration is mostly 50-60 days. The latter stage displaces the most, draining about 60-70cm per day for a duration of 30-45 days. The growth cycle of the South American white shrimp in this region is mostly 110-130 days, and the majority of the shrimp are raised 2 times a year, and the survival rate is about 35%-55%. Regarding the input of feed, factory farming generally only throws compound feed. In addition, every year, farmers have to clean the pond disinfection, the frequency is twice a year.
