Scientists in Hungary accidentally created a new hybrid fish called 'sturddlefish' by combining Russian sturgeon and American paddlefish during an attempt to breed endangered sturgeons, resulting in a rare and unintended hybrid species.
Bodycam footage shows Sturgeon police officer Myron Woodson shooting and killing an injured and possibly rabid dog after failing to capture it, sparking public outcry and a petition for his removal. The city defends Woodson's actions, citing the lack of animal control and the dog's potential threat to public safety. A community meeting is scheduled to discuss the incident.
Michigan's Department of Natural Resources canceled the 2024 Black Lake sturgeon fishing season due to the risk of excessive harvest and rapidly melting ice, marking the first cancellation in the state's history. The decision aims to protect the threatened sturgeon population and ensure angler safety. Despite the cancellation, the nonprofit Sturgeon for Tomorrow will still host its annual Shivaree fundraiser to support sturgeon recovery, protection, and conservation efforts.
The Michigan Department of Natural Resources has canceled the 2024 lake sturgeon fishing season on Black Lake due to concerns about marginal ice conditions and the inability to effectively track harvests. The cancellation aims to protect the lake sturgeon population and ensure the safety of anglers and staff. Despite the fishing season being called off, the annual Black Lake Sturgeon Shivaree event will still take place, featuring live music, a poker run, and activities for kids. Efforts to rehabilitate the lake sturgeon population in Michigan have been ongoing due to habitat loss, overfishing, and declining populations since the 1800s.
Researchers have discovered that in early branches of the fish family tree, such as the sturgeon, the neural crest cells form the bony armor that covers them, suggesting an ancient role in bone formation that dates back to armored fish in the Devonian period. This finding sheds light on the origin of bone formation and challenges the conventional understanding that bone formation is limited to a small population of neural crest cells. The study focused on lineages like the gar and sturgeon to investigate whether the neural crest contributes to armor formation in these fish.
A new study using sturgeon fish has found that trunk neural crest cells are responsible for the development of bony scutes, the protective armor found in fish. These cells migrate throughout the fish's body and give rise to bone-forming cells, providing evidence for the evolution of dermal armor in vertebrate fish. The research sheds light on the evolutionary history of fish and the role of neural crest cells in the development of protective coatings.
