“…Application of chemical P fertilizer also increases P accumulation in the soil. Although P-bearing organic amendments such as 'green manure' and animal manure are less frequent in IRCC, chemical P is often applied to supply the P required for rice growth and to increase the nutrient level in the water to cultivate natural crayfish prey such as rotifers and algae (Gong et al, 2012), the latter of which can degrade the quality of surface water (Table 1). Thus, the increased TP accumulation in rice paddy soils under IRCC is due mainly to the excessive amounts of P from feeds and chemical P fertilizer.…”

China has experienced an increase in integrated rice–crayfish (Procambarus clarkii) culture (IRCC) in rice paddies. However, whether the current regime degrades phosphorus (P) fertility in rice paddies remains unclear. To assess changes in P fertility, the surface soil (0–20 cm) of high‐yield rice paddies with 3, 6, and 10 consecutive years of IRCC was sampled in Honghu County in the Jianghan Plain region, China. Adjacent fields planted with long‐term rotations of rice and dry‐season crops (RRD) were also sampled. Total P (TP), available P (Pa), organic P (Po) compounds, and P fractions in soils were intensively assessed using chemical digestion, NaHCO3 extraction, 31P nuclear magnetic resonance, and sequential chemical extraction. IRCC significantly increased organic matter, total nitrogen, TP, Fe(II), and S2− contents of rice paddy soils and nutrient concentrations in the surface water, with a distinct decrease in total Fe and pH. Consecutive IRCC greatly influenced P fertility. Continuous P accumulation in rice paddy soils accelerated greatly, with a mean increase of approximately 43 mg·kg−1·yr−1. Pa was 67% higher after 3 years of IRCC, compared with RRD, but 78% lower after 10 years. Consecutive IRCC induced a decrease in Po compounds, with a mean decrease in TPo of approximately 20 mg·kg−1·yr−1. Long‐term consecutive IRCC increased transformation of Pa, Fe(II)–P, and Po into Ca–P and Fe(III)–P, increasing mean Ca–P and Fe(III)–P concentrations by approximately 69 and 7 mg·kg−1·yr−1, respectively. Our results suggested that long‐term consecutive IRCC degrades P fertility in rice paddies, and implementing IRCC in high‐yield rice paddies is not recommended.

“…The red swamp crayfish, Procambarus clarkii, is widely distributed in natural environments (Lodge et al, 2012), and it is also a cultured species worldwide (Gong et al, 2012;Jin et al, 2019). Due to its economic importance for aquaculture, its immune system has been extensively studied (Dai et al, 2017;Du et al, 2016;Wu et al, 2017;Zhou et al, 2017).…”
