Unreasonable discharge of manure from livestock and poultry breeding is a main source of agricultural non-point source pollution in China, but the manure is also a potential resource. How to achieve the best resource utilization of livestock manure and reduce environmental pollution has become a major problem that must be solved in the sustainable development of China’s breeding industry. In this paper, the pollutant discharge coefficient method is used to calculate the amount of manure produced by livestock and poultry breeding in China, and the current situation and problems of its resource utilization are analyzed.

Strategic Study of CAE 2017, Volume 19, Issue 4, Pages 130-137 doi: 10.15302/J-SSCAE-2017.04.021
This paper summarizes the development of utilization models for the return of livestock and poultry manure to farmland in China. It analyzes the problems affecting the industrial development of the utilization of livestock and poultry manure recycling, and discusses development strategies for the next step in this process. In past years, important progress has been achieved in exploring utilization models for returning livestock and poultry manure to farmland, and in identifying suitable parameters for the farmland carrying capacity of livestock, both at home and abroad. However, problems remain such as unbalanced nutrients after combining planting and livestock systems, large nutrient losses, and a lack of reasonable principles for manure application on farmland. In the next step, studies should be based on the concept of the environmentally friendly return of manure to farmland and should introduce the concept of nutrient management after combining planting and livestock systems. Techniques should be carried out for the collection, storage, and processing of manure; for its return to farmland; for reasonable manure applications; for balancing nitrogen and phosphorus nutrients in order to reduce non-point source pollution; and for other aspects. In addition, policies about the efficient recycling of livestock and poultry manure should be promoted.

Agricultural non-point source pollution is one of the main factors causing water pollution in China. Due to its characteristics of randomness, unfixed pollution discharge, and changes in pollution load, it is more difficult to control and prevent the pollution from non-point sources than that from point sources. Making clear of the current situation of non-point agricultural pollution and its prevention and control technologies is the premise of non-point pollution control. This paper summarizes the causes and present situation of agricultural non-point source pollution, and points out that the unreasonable fertilizer application and the pollutant discharge from large-scale livestock and poultry breeding farms are the most important sources of agricultural non-point pollution. The current mature non-point source pollution prevention and control techniques in planting and livestock industry are introduced. It also proposes that the combination of source control, process control, and end treatment is the most important prevention method for agricultural non-point source pollution. Corresponding prevention and control technologies of non-point source pollution should be adopted according to local conditions to realize the simultaneous development of environmental, economic, and social benefits.

Stocking density is widely recognized as a critical husbandry factor in modern intensive aquaculture and inappropriate stocking density is a potential source of chronic stress that may affect the welfare of farmed fish, and increase breeding risk. So far the effect of stocking density on the fish welfare was studied widely. In order to provide reference for selecting suitable stocking density and further researching, this review will focus on the fish welfare indicator such as growth performance, health status, stress response and behavior, to explore how stocking densities affect fish welfare.

Strategic Study of CAE 2015, Volume 17, Issue 1, Pages 4-10
In order to preferably evaluate breeding effect and environmental sustainability of recirculating aquaculture mode， the emergy flow chart of Cynoglossus semilaevis Günther in industrial recirculating aquaculture was built to analyze the emergy of different parts in the aquaculture mode. The results showed that： The environment emergy input occupied only 1.08 %， emergy yield ratio (EYR) was 2.433， emergy loading ratio (ELR) was 0.313 4， and emergy sustainable index (ESI) was 7.763， indicating that agricultural production was promoted to the level of industrialization with the use of this kind of aquaculture mode， which gains highly developed economic system and higher production efficiency； meanwhile， this kind of aquaculture mode greatly alleviates the pressure of environment and gains higher sustainability and carrying capacity.

With the growing scale of the mariculture industry, the problem of storage overcapacity in aquaculture has caused serious damage to the aquatic environment and the aggravated the dangers of disease, which have hurt the sustainable development of this industry in the long term. So it is urgent to strengthen the research on carrying capacity and to set up the scientific and adaptive management strategies. This paper reviews the progress of research and existing problems relating to the mariculture industry’s carrying capacity for cage, shellfish, macroalgae, etc; it also points out the key technologies behind capacity evaluation, including the index system of ecological capacity assessment, the numerical model of individual growth of cultured organisms, the coupling of hydrodynamic processes and ecological models; Furthermore, this article analyzes the role of carrying capacity in determining the current population density of maricultural farms and optimizing the layout of the mariculture operations, expanding the maricultural farming space and building a new mode of maricultural farming. And then, this paper advanced three suggestions for developing a capacity evaluation system in aquaculture waters, including establishing the long-term monitoring experimental station of the offshore aquaculture structure, culture capacity assessment, setting up research initiatives for aquaculture capacity research, and identifying the layout and structural adjustment for establishing a ecosystem management strategy.

Based on patent retrieval and analysis with the Thomson Innovation (TI) database, the international development trend of recirculating aquaculture system (RAS) is investigated. The current international research and development focus for RAS are purification technology, aquarium structure, water temperature control, and biological filters and filter devices. Meanwhile, China has focused on fish tank and pond design, biological filters, RAS devices, oxygen supply and motor shaft, etc. Though some of the international research focus in RAS are new for China, the number of Chinese patents is greater than the international average and has grown rapidly in recent years, indicating a positive developmental trend in the near future. This paper provides recommendations for improving efficiency, quality, safety, and environmental protection of sustainable aquaculture as well as further measures for the development of RAS in China.
