Overview

Examines hydrobiocenosis in biofilters, highlighting species distribution and diversity in aquaculture systems.

Key Points

  • The research aims to analyze the composition and distribution of hydrobiocenosis within biofilters of recirculating aquaculture systems.
  • Identified periphyton species in the biofilter by sampling at different depths.
  • Analyzed spatial distribution across substrate surfaces oriented in upward and downward directions.
  • Measured taxonomic diversity and community composition using the Jaccard index.
  • Identified 38 species from nine taxonomic groups, with ciliates representing 52.6% of the diversity.
  • Periphyton abundance varied from 29,443 to 31,630 thousand specimens/m2 at different depths.
  • Significant differences in species composition were found between upward and downward facing substrate surfaces.
