Major Decline in Australia's Giant Cuttlefish Breeding Season
Numbers in one of the world's largest cuttlefish breeding events have plummeted by 97 percent to a record low, raising concerns.
Australia's annual giant cuttlefish breeding season saw a record low turnout this year, with numbers dropping by 97 percent to 1,811.
Record Decline in Breeding Season
Australia normally hosts the world's largest cuttlefish breeding event, but participation this year was recorded at its lowest level ever. According to official data, only 1,811 cuttlefish arrived to breed this year, compared to 63,000 last year.
Effects of Toxic Algal Bloom
The state government states that a toxic algal bloom, which has been ravaging the coastline for more than 18 months, may be responsible for this sharp decline. Exacerbated by ocean warming and climate change, this situation has negatively impacted South Australia's marine life habitats.
Worrying Decrease in Egg Numbers
Since adult cuttlefish generally die after breeding, each season is of critical importance for the future of the species. While millions of eggs are normally laid, it was determined that only 440 eggs were counted in recent months.
Expert Opinions and Future Concerns
The low figures triggered calls for the species to be added to the endangered species list. While researchers and trusts warn of serious risks, some experts note that populations have experienced fluctuations in the past.
