Abstract

Starvation significantly impacts fish species, affecting various organs. This study examines the effect of prolonged starvation on glycogen content in the gonadal tissue of Clarias batrachus, a freshwater catfish. Using a calorimetric method, glycogen levels in gonadal tissues were measured over a 40-day period at 10-day intervals. Results showed a gradual decline in glycogen content, likely due to increased gluconeogenesis and heightened rates of deamination. Male specimens exhibited a more pronounced glycogen depletion compared to females. Initially, the reduction was minimal up to 20 days, followed by a sharp decline, resulting in an 80% reduction by day 40. These findings highlight significant metabolic adaptations in Clarias batrachus during prolonged starvation.
