Description

The system includes energy production (red), feed production (green), the main chain of aquaculture production (blue), and the production of other inputs (purple). When using this data set, attention should be paid to the geographic specificity of the data, extracted from the prefecture-level city of Ningde. Users should consider the seasonal and regional variability in aquaculture practices. Care should also be taken to include or exclude energy and feeds production-related impacts according to the aim of the study. Inclusion of appropriate life cycle stages (e.g., breeding, feeding) depending on the scope of the assessment is essential to maintain accuracy and relevance of the findings.

Technology

The cage seedling cultivation technology of large yellow croaker, the sea area is selected as small and medium wave area, the water depth at low tide is ≥8 m, the flow rate is smooth, the flow rate is less than 1.5 m/s, and the flow direction is smooth and stable. The sea area with high flow rate which can be controlled by technical measures can also be used as aquaculture area. Water quality should comply with the provisions of GB 11607, water temperature: 8 ℃ ~ 31 ℃; Salinity: 13 ~ 35. The area of a single cage is 16 m 2 ~ 100 m 2, and the net depth is 4.0m ~ 8.0m. Net mesh 3 mm ~ 15 mm, adjust the size according to the specifications of the fish, in order not to escape the fish as the principle.Breeding feed includes large yellow croaker compound feed and fresh and mixed fish ingredient bait.
