Fish Diversity in Abalone Raft Culture Areas of the Pingtan Sea, China

A 2024 study from March to August assessed fish diversity in the Pingtan Sea, China, comparing an abalone raft culture area to a control area. The dataset, authored by Chao Ma and published on figshare, integrates results from traditional fishing gear and environmental DNA (eDNA) metabarcoding. It includes metrics such as species counts, diversity indices, and catch per unit effort (CPUE).

Use Cases

• Compare fish community structure between aquaculture and control areas based on species lists and diversity indices.
• Assess the effectiveness of eDNA metabarcoding versus traditional sampling methods for biodiversity monitoring.
• Analyze the relationship between habitat heterogeneity from aquaculture structures and fish resource abundance based on CPUE data.
• Model the role of aquaculture facilities as artificial reefs based on the integrative assessment framework.

Strengths

• Integrates two distinct biodiversity assessment methods: traditional fishing (gillnets, pots) and eDNA metabarcoding.
• Provides specific quantitative results: 35 fish species identified via traditional methods in the raft area, 68 species via eDNA, and significant differences in diversity indices (P<0.05).
• Clear temporal and spatial scope: surveys conducted from March to August 2024 in the Pingtan sea area, China.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for certain analyses.
• The dataset is very small (10.0 KB), suggesting it may contain summary results rather than raw observation records.
