Overview

Analysis reveals diminishing resilience and increased fishing pressure on Sarotherodon melanotheron in Lake Toho, suggesting unsustainable practices.

Key Points

  • Overfishing leads to significant declines in the resilience potential of Sarotherodon melanotheron.
  • Fishing pressure has resulted in a reduction of mature individuals from 69.27% to 55.07% in two decades.
  • Average size and weight of Sarotherodon melanotheron individuals have decreased, indicating higher juvenile exploitation.
  • Growing overexploitation jeopardizes local food security and compromises fish population sustainability.
