Sediment Microbial Community Data from Grass Carp Aquaculture Ponds in Northern China

A dataset from figshare containing measurements of bacterial and archaeal communities in aquaculture pond sediments. The data includes abundances, diversities, and co-occurrence network metrics for microbes involved in nitrite/nitrate-dependent anaerobic methane oxidation (N-/Nr-DAMO). It was collected by Yan Chen from sediment samples taken at 0-15 cm depths in May, July, and September.

Use Cases

• Analyzing vertical distribution patterns of microbial abundance and diversity based on sediment depth intervals
• Comparing microbial community complexity and stability between aquaculture and natural ponds based on co-occurrence network metrics
• Investigating niche differentiation of N-/Nr-DAMO microbes based on functional gene copy numbers and relative abundances
• Studying the relationship between environmental factors like ORP and nutrient availability and microbial community structure

Strengths

• Data includes temporal variation across three distinct farming seasons (May, July, September)
• Spatial variation is captured through sediment samples collected at 5 cm intervals within a 0-15 cm depth range
• Quantitative measurements include copy numbers of functional genes (pmoA, mcrA) determined by qPCR
• Community composition data is derived from high-throughput sequencing analysis

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• The dataset is small (39.8 KB), indicating limited scope
