“…For example, in 2015, 190 marine ranches had been built in China, and an estimated 619.8 km 2 of coastal waters was covered with artificial reefs with a volume of 60.94 million m 3 along the coast of China (Chen, 2020). Meanwhile, 167 billion cultured juveniles (e.g., sea cucumber A. japonicus and abalone Haliotis discus hannai) were released by the government and private industry along the Chinese coast over the last two decades (Liu et al, 2022). The results of our study highlight the different ecosystem consequences of stocking two different species at different densities and the importance to managers of taking this information into account when designing their enhancement practices.…”

Estimating ecological carrying capacity for stock enhancement in marine ranching ecosystems of Northern China

Marine ranching has been proposed as a promising solution to manage the depleted coastal fishery ecosystem in recent decades across China. Marine ranching integrates the practices of artificial habitat-based with aquaculture-based enhancement. Assessing the ecological carrying capacity of target species for enhancement is a precondition for determining the optimal numbers for release, particularly for those species whose habitat restrictions have been eliminated through the construction of artificial habitats in the marine ranch. A responsible approach to stock enhancement aims not only to increase total yield and stock abundance but also to consider any potential effects on ecosystem structure and function. A time-dynamic, ecosystem model was constructed using Ecopath with Ecosim for the Laizhou Bay (Bohai Sea) marine ranching ecosystem in the nearshore waters of northern China. Two sedentary target species with potential for stock enhancement, i.e., the carnivorous red snail Rapana venosa and the detritivorous sea cucumber Apostichopus japonicus, were selected to simulate and estimate their ecological carrying capacities and project their overall effects on the ecosystem. Ecological carrying capacity was defined as the maximum standing stocks of the target species that would not cause “unacceptable” impacts on the ecosystem function and resilience, i.e., not cause any other group’s biomass to fall below 10% of its original biomass. The ecological carrying capacities estimated for R. venosa and A. japonicus were 623.46 and 200.57 t·km−2, respectively, corresponding to 7.8 and 5.0 times higher than their current standing stocks. Simulations of R. venosa enhancement showed distinct effects of increased target species abundance on other functional groups and ecosystem properties. An increase in red snail biomass caused negative impacts on the biomass of most other functional groups and ecosystem indicators, such as Finn’s cycling index, transfer efficiency, and Kempton’s Q index. In contrast, the simulated A. japonicus enhancement had relatively few impacts, and the biomasses of most other functional groups and ecosystem indicators did not change or changed very slightly (<5%). The current model framework provides a means of estimating the ecological carrying capacity in commercial-scale stock enhancement practices and avoiding potential ecological risks for marine ranching in northern China.

“…Mariculture provides biodiversity and stock enhancement through at least two pathways: first, as of 2015, 167 billion juveniles of nine marine species groups were cultured and released along the Chinese coast. Hence, the success of biodiversity conservation and stock enhancement activities depends upon mariculture-based artificial breeding and cultural juvenile release (Liu et al, 2022). Second, the mariculture system, especially suspended or elevated rafts and cages, can be viewed as three-dimension habitat and can positively influence the structure and function of wild macrofaunal communities through at least three pathways: provision of structured habitat, provision of food resources, and enhanced reproduction and recruitment.…”

China is the biggest provider of mariculture products, and the industry is still growing rapidly. Increasing scientific evidence indicates that mariculture may provide valuable ecosystem goods and services in China. Here, we performed a systematic literature review of studies with the aim of understanding the ecosystem services of mariculture and a comprehensive review of ecosystem approaches that may improve mariculture ecosystem services and goods in China. We highlight four ecosystem services functions in China, including food supply, nutrient extraction, carbon sequestration, and biodiversity conservation. Given the further reform of China’s mariculture, we outlined several ecosystem approaches including integrated multi-trophic aquaculture (IMTA), carrying capacity assessment and monitoring, marine spatial planning, and waste treatment and recirculating mariculture system. We conclude that the ecosystem services of the ecosystem approach to mariculture provide an unprecedented opportunity for the reform of China’s sustainable aquaculture. Finally, a synthesis of sustainable development of mariculture, along with the five recommendations for future mariculture development in China, is outlined.
