“…The formation processes of mariculture nutrient extraction are complex but through at least four pathways. First, seaweed can absorb dissolved nitrate and phosphate in seawater and convert dissolved inorganic nitrate and phosphate into particle organic matters during their growth (Xie et al, 2020). Second, mollusks, especially filter-feeding bivalves, can filter particle organic matter and then accumulate nitrogen and phosphorous (Mahmood et al, 2016).…”

“…The finfish-bivalve-seaweed (Figure2A) and finfish-seaweed (Figure2B) IMTA mode is popular in Zhejiang, Fujian, and Guangdong provinces; these implementations can alleviate the negative environmental and ecological effects of finfish culture, such as eutrophication. For instance, finfish culture produces waste (uneaten fishmeal, faces, and dissolve nutrients) in the water, and the filtered bivalve can remove the particle organic matter (POM), while the seaweed can absorb the dissolved nutrient in the water (Wei et al, 2017;Xie et al, 2020). The bivalve-seaweed (Figure 2C) mode is deployed in nearly all coastal provinces of China.…”

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.

“…Complementary to physical techniques, biochemical monitoring can trace the source of waste from aquaculture system to further identify environmental change caused by aquaculture effluent. Biochemical tracing techniques such as fatty acid (FA) analysis [116], stable isotopic signatures [117] and soya DNA [118] are relatively recent innovations now used increasingly as effective monitoring tools to trace mariculture waste in the water column or benthic system. They could effectively differentiate between aquaculture waste and marine source waste, as well as information on the overall influence of mariculture in marine ecosystems.…”

While marine aquaculture, or mariculture, has been growing rapidly and globally in recent decades, many environmental concerns remain to be fully addressed to achieve its long-term goal of sustainable development. This paper aims to provide a synthesized perspective on these issues by reviewing and discussing the characterization, transport, and current modelling and management tools associated with effluents released from mariculture sites. Specifically, we examined the effluent characteristics and behavior from source-to-sink, including the composition and load of effluent discharge, its transport and transformation processes in the water column and at the seabed, and its impacts on the pelagic and benthic environments. We then focused on management-related issues, including the setting of the regulatory mixing zone, the establishment of environmental standards, monitoring measures, and modelling techniques to depict the current state-of-the-art modes in a global context. Our study shows that while substantial progress has been made in understanding the nature of the mariculture effluent, as well as in monitoring and modelling its transport and fate, the regulatory framework still lags behind in many countries where the mariculture industry is relevant. This is particularly evident in the lack of consistent criteria for the definition of regulatory mixing zones and the associated environmental standards for water quality and benthic impacts. Besides, as new predictive models are emerging quickly, their proper evaluation and validation are imperative in view of their increasing application in regulatory practices. This review is intended to provide references for advancing regulatory management of mariculture effluents, as well as for promoting sustainable mariculture development.

“…However, for a long time, the breeding industry has been facing various problems such as energy consumption and environmental pollution. Bin Xie et al [1] used the stable isotopic values of SPOM to label suspended particulate organic matter in dense cage culture to assess the level of water pollution. Gizachew Hailegebreal et al [2] studied the morbidity and mortality of chickens in poultry farms, concluding that infectious diseases were the main constraint to increasing chicken production.…”

Aiming at the problems of high energy consumption and particle breakage in the pneumatic conveying process of large-scale breeding enterprises, in this paper, based on the theoretical calculated value of particle suspension velocity, a computational fluid model and a discrete element model are established based on computational fluid dynamics (CFD) and discrete element method (DEM). Then, through the numerical simulation of gas-solid two-phase flow, the influence of four factors of conveying wind speed, particle mass flow rate, pipe diameter, and particle size on the velocity distribution of particles in a horizontal pipe, dynamic pressure change in the pipe, pressure drop in the pipe, and solid mass concentration are studied. The results show that the k-ε turbulence model can better simulate the movement of gas-solid two-phase flow, and through the analysis of the simulation, the influence of four different factors on the conveying characteristics is obtained, which provides a scientific basis for the construction of the conveying line.
