Overview

Longitudinal study shows GSI trends in Heteropneustes fossilis related to water quality and rainfall impacts.

Key Points

  • This research aims to assess the gonadosomatic index (GSI) of stinging catfish and its relationship with water quality and climatic variables.
  • Longitudinal study conducted in an earthen pond (2022–2024)
  • Analyzed reproductive performance through GSI measurement
  • Used ANOVA to assess differences in gonad weight and GSI
  • Forecasted GSI trends using SARIMA model based on 31 months of data
  • Female GSI peaked at 26.17 during spawning in June, while males peaked at 1.54 in July
  • Significant differences in GSI found across prespawning, spawning, and postspawning periods
  • Strong positive correlations observed between female GSI and water temperature, air temperature, and rainfall
  • SARIMA forecasts predicted a decline in GSI for 2024–2025, projected at 22.89 for June 2025
