“…It is independently reported that large‐scale IFA threatens not only the coastal and inland water ecosystems but also results in losses linked with high fish concentration. There are also concerns about whether it will be possible to provide sufficient feed for all the new IFAs being built 13 . Mutual injuries and other stress factors increase the incidence of disease vectors and slow fish growth 14 .…”

“…However, potential increase in aquaculture production is limited by environmental challenges and resource constraints (Klinger and Naylor, 2012;FAO, 2020). Integrated multi-trophic aquaculture, which involves the cultivation of fed species (e.g., finfish or shrimps fed sustainable commercial diets) with extractive species (e.g., suspensionand deposit-feeders, or seaweeds or other aquatic vegetation), is considered an effective solution to meet the demands of aquaculture production and achieve sustainable aquaculture development (Chopin et al, 2001;Abreu et al, 2011;Dong et al, 2022).…”

Temporal Dynamics in Energy Fluxes and Trophic Structure of a Portunus trituberculatus Polyculture Ecosystem During Different Culture Periods

Swimming crab (Portunus trituberculatus) are an important aquaculture species in eastern coastal areas of China. To improve the understanding of P. trituberculatus culture ecosystem functioning, the dynamics of energy flow and trophic structure of a P. trituberculatus polyculture system (co-culture with white shrimp Litopenaeus vannamei and short-necked clam Ruditapes philippinarum) were investigated in this study. Three Ecopath models representing the early, middle, and late culture periods of a P. trituberculatus polyculture ecosystem, respectively, were constructed to compare ecosystem traits at different culture periods. The results demonstrated that detritus was the main energy source in this polyculture ecosystem, and most of the total system throughput occurred at trophic levels I and II. Artificial food input and consumption by the culture organisms increased from early to middle and late periods, which produced marked impacts on biomass structure and primary production. R. philippinarum was considered to have a dominant influence on phytoplankton community dynamics which changed from nano- to pico-phytoplankton predominance, from the middle to the late period. Considering the low utilization efficiency of pico-phytoplankton production, large amounts of detritus accumulated in the sediment in the late period, which may constitute a potential risk for the ecosystem. Ecological network analyses indicated that the total energy flow and level of system organization increased from the early to the middle and late periods, whereas food web complexity and system resilience decreased from early to middle and late periods, which may indicate a trend of decreasing ecosystem stability. The system may be further optimized by increased stocking density of R. philippinarum and by introducing macro-algae at a suitable biomass to increase ecosystem stability, energy utilization efficiency, and aquaculture production.

“…The fish-lighting complementary PV power mode is aligned with the concept of green development. Furthermore, research has shown that the integration of aquaculture and solar power generation can improve the economic efficiency and employment level of aquaculture systems (Dong, et al, 2022), and play an important role in aquaculture's ability to resolve energy demands (Li, et al, 2020b). Consequently, the "Fishery-PV Integration" mode has broad developmental prospects.…”

“…In recent years, aquaculture has developed rapidly, but its level of intensification is low and mainly based on extensive farming (Dong, et al, 2022). One important reason is that intelligent fishery facilities and equipment consume a large amount of electricity, which increases the cost of farming.…”

Background: “Fishery-photovoltaic (PV) Integration” is a novel aquaculture model which aims to combine green energy with modern fisheries to improve socioeconomic benefits while ensuring aquaculture production and electricity consumption. To determine the practicability of the “Fishery-PV Integration” model, an experiment was conducted with Penaeus monodon as a model, in which the growth rates of shrimp, water quality conditions, and the micro-ecological environment were studied. Results: After 105 days of rearing, P. monodon (initial weight of 0.006 ± 0.001 g) reached an average body weight of 11.69 ± 0.92 g. The water quality was stable (C(NH4+) ≤ 1.57 mg/L), and the shrimps were healthy. It was determined via metagenomics and 16S rRNA gene sequencing that the dominant phyla present in shrimp intestines, water, and effluent were Proteobacteria, Actinobacteriota, Bacteroidota, and Verrucomicrobiota. In addition, a large number of nitrogen-fixing bacteria in the “Fishery-PV Integration” pond, which were helpful to maintain the stability of the water quality. The relative abundance of Vibrio as a common opportunistic pathogen for shrimp was relatively low, which is beneficial to promote the healthy growth of shrimp. In addition to maintaining water quality stability, microorganisms played an essential role in regulating intestinal amino acid metabolism, carbohydrate metabolism, and energy metabolism. In the water and effluent, a high proportion of ABC transporters and quorum sensing play an important role in mitigating environmental toxins and regulating the physiological and metabolic activities of microbial communities. Notably, only 123 antibiotic resistance genes (ARGs) were identified within the “Fishery-PV Integration” pond. This result is significantly lower than the numbers found in other studies, indicating that shrimp cultured in the “Fishery-PV Integration” pond had a higher level of food safety. Conclusions: This paper was the first reported the “Fishery-PV Integration” culture mode and preliminarily reveal the characteristics of the microflora and ARGs distribution in a “Fishery-PV Integration” pond. The results show that “Fishery-PV Integration” farming is a sustainable, green, and safe culture method.
