Ahli biologi nasional menyelidiki kasus maraknya kematian hiu macan tutul selama sebulan terakhir. Ahli biologi mengatakan, kimia dalam tubuh ikan ini turun drastis dari ambang seimbang akibat air tawar yang mengalir ke laguna tempat hiu melahirkan dan mencari makan.
“Jika air tawar terlalu banyak dan salinitas rendah, hal ini bisa berdampak buruk pada ikan,” ungkap ahli biologi laut Carrie Wilson di California Department of Fish and Game.
Lebih dari 100 hiu macan tutul anak-anak dan dewasa ditemukan mati pada pertengahan April lalu.
Hiu ini bisa tumbuh sepanjang 1,5 meter dan hidup selama 40 tahun lebih. Hiu ini sering kali dijumpai di pesisir dangkal dari Oregon hingga Mexico
Wildlife officials say, the rampant death leopard sharks in San Francisco Bay allegedly due to heavy rains during the winter. Like what?
National biologists investigating the death of the rampant cases of leopard sharks during the last month. Biologists said the chemical in the body of this fish is down dramatically from the brink of a balanced result of fresh water flowing into the lagoon where sharks give birth and find food.
"If too much fresh water and low salinity, this could have a negative impact on fish," said marine biologist Carrie Wilson at the California Department of Fish and Game.
More than 100 leopard sharks and adult children found dead in mid-April.
This shark can grow as long as 1.5 meters and live for 40 years. Sharks are often found in shallow coastal areas from Oregon to Mexico
