“…The EU, USA and Japan comprise the bulk of global revenues, which offer excellent marketing opportunities to exporting countries, and developing countries in particular (Dolan et al, 1999;Willer and Yussefi, 2007). They have compliance [1] and equivalence [2]-based mechanisms for enabling their systems to accommodate the flow of trade in organic products (Table I). Agricultural products imported from other countries can only be marketed as organic if their production, processing, documentation, inspection and certification systems are considered as "equivalent" or "compliant".…”

AbstractPurpose -This paper aims to chart the breadth and acceleration of organic markets domestic and international and discuss the obstacles and possible ways that confront enterprises who engage in organic exports from and imports to China. Design/methodology/approach -There is much extant research that investigates the organic certification and its market development in the developed world. However, little emphasis is given to China, the highest growing organic market. This research aims to narrow this gap in the literature by reviewing organic certification and the market in China. Findings -China's organic products are mainly exported to developed countries, but the growing affluence of Chinese consumers and expanding foreign expatriate community in China is developing a domestic market for organic food. Organic products are increasingly being imported. Organic standards and certification system in China have been established and under the implementation, with all stages of the organic marketing chain regulated by law and guaranteed. The lack of an equivalent or compliant system forces Chinese organic exports to enter the international market through multi-certification, and foreign organic imports to the China market possibly through certification by a CNAS-ACB. Originality/value -This paper provides a unique insight into a wide range of China organic certification systems and the mechanism for organic exports from and imports to China.

“…Pond aquaculture greatly contributes to the production of freshwater fish due to the advancement of intensive aquaculture technology. In intensive pond culture, fish are stocked at high densities and fed with formulated feed, and aeration and water exchange are frequently used to maintain excellent water quality (Xie, Qin, Yang, Wang, Wang & Li 2013). However, the heavy loading of formulated feed to fish ponds has caused serious nutrient (nitrogen and phosphorus) wastes due to low nitrogen retention efficiency (<45%) in warm water fish fed formulated feed (Chai, Ji, Han, Dai & Wang 2013).…”

Bacterial composition, abundance and diversity in fish polyculture and mussel-fish integrated cultured ponds in China

et al. 2016

Bacterial community and abiotic environmental parameters in twelve freshwater aquaculture ponds were analysed. According to the major component of stocked animals, the ponds were grouped into four types: black carp Mylopharyngodon piceus, largemouth bass Micropterus salmoides, yellow catfish Pelteobagrus fulvidraco and pearl mussel Hyriopsis cumingii ponds. Each type of pond was stocked with three species of Chinese carps (silver carp, bighead carp and gibel carp) to form a unique mode of fish polyculture or mussel–fish integrated culture. The bacterial composition was identified using 16S rDNA sequencing. Totally, 3701 and 11 150 operational taxonomic units (OTUs) were identified from the water and sediment samples respectively. The number of OTUs, abundance‐based coverage estimator, Chao1 index and Shannon diversity index were lower in the water column than in the sediment, suggesting that diversity and stability of bacterial community were higher in the sediment. In the water column, Proteobacteria, Actinobacteria and Bacteroidetes dominated at the phylum level, and 26 dominant genera were identified. In the sediment, Proteobacteria, Chloroflexi, Bacteroidetes, Acidobacteria and Nitrospirae dominated at the phylum level, and 25 dominant genera were identified. Bacterial compositions between the ponds with different aquaculture modes were similar at the phylum levels, but varied at the genus levels. The bacterial composition in the ponds was correlated with hardness, ammonia and total nitrogen in the water column. This study indicates that the type of aquaculture mode is a factor regulating the microbial community, which provides an insight towards microbial management through probiotic manipulation in pond culture.

“…Polyculture systems have been used for centuries in China and are probably the best examples of successful sustainable aquaculture (Xie et al, 2013). The idea of polyculture is based on the principle that each species stocked has its own feeding niche that does not completely overlap with the feeding niches of other species.…”

Summary Freshwater polyculture systems should efficiently utilise natural food resources and pond habitats with the consequent effects of reducing costs and increasing productivity. However, understanding of the primary carbon sources and food web within polyculture ponds, and especially macrophyte‐dominated ponds, remains limited. Stable‐isotope analysis was used to identify the main carbon sources and describe the trophic patterns of freshwater fauna in a polyculture pond around Lake Gucheng, China. An isotope mixing model (SIAR) was also used to estimate the relative contribution of four basal sources (suspended particulate organic matter [SPOM], sedimentary organic matter [SOM], macrophytes and epiphytes) to invertebrates and different fish trophic groups. Basal resources showed distinct δ13C values, ranging from −24.3 to −20.5‰, which allowed for a powerful discrimination of carbon sources. Consumers were also well separated in δ13C (−24.0 to −20.0‰ for invertebrates and −24.4 to −18.9‰ for fish), suggesting considerable differences in ultimate sources of carbon. Results from the SIAR model indicated that epiphytes were the most important carbon sources for crustaceans, herbivorous fish, omnivorous fish and piscivorous fish, while SPOM made the highest contribution to zooplankton, chironomids, molluscs, annelids, planktivorous fish and benthivorous fish. Mean δ15N values, combined with calculated food source contributions, were used to elucidate the food‐web structure of this polyculture pond, which suggested that carbon fixed by primary producers could be transported up the food chain to piscivorous fish through four main trophic pathways: one based mainly on SPOM, one on both SPOM and SOM, one on SPOM, SOM, macrophytes and epiphytes, and one based on both macrophytes and epiphytes. Our results emphasised the trophic importance of epiphytes on submerged macrophytes, a key component in the polyculture ponds, for the main culture species: Chinese mitten crab (Eriocheir sinensis: Varunidae), freshwater shrimp (Macrobrachium nipponense: Palaemonidae), and high‐value piscivorous fish. This study also revealed the high level of complexity of polyculture pond food webs, and suggests that a diversity of major trophic pathways may be a characteristic of macrophyte‐dominated aquatic ecosystems.
