Jellyfish Bycatch and Collagen Data from Spanish Mediterranean Small-Scale Fisheries

A study document details a 13-month monitoring program of jellyfish bycatch in Catalonia and the Valencian Community, Spain. The research assessed fishers' perceptions and quantified species composition, with Rhizostoma pulmo and Pelagia noctiluca as the most abundant. Collagen extracted from bycatch R. pulmo was analyzed for molecular integrity using SDS-PAGE, FTIR, and XRD.

Use Cases

• Analyzing fishers' engagement and perceptions of bycatch valorization based on semi-structured interview results.
• Quantifying jellyfish bycatch occurrence and species composition based on 13 months of monitoring data.
• Evaluating the quality of marine collagen for biotechnological applications based on structural and molecular integrity tests.
• Assessing the feasibility of circular bioeconomy strategies for small-scale fisheries based on interdisciplinary framework findings.

Strengths

• Provides a 13-month quantitative baseline for jellyfish bycatch in the study area.
• Collagen quality from bycatch was validated using three analytical techniques: SDS-PAGE, FTIR, and XRD.
• Data includes perspectives from fishers across four small-scale fishing guilds.

Limitations

• Dataset is a 696.1 KB DOCX file; row count and column-level documentation are absent.
• Data is limited to a specific geographic region (Catalonia and Valencian Community, Spain).
• Freshness should be verified as the last update date is in the future (2026-05-11).
