The Atlantic sturgeon and dinosaur shared the same environment and have a slight similarity today. Their backs are coated in bone plates known as scutes rather than scales. They are the largest natural fish to the Chesapeake Bay, reaching lengths of up to 14 feet and weights that are almost equal to horses (about 800 pounds).
The Bay previously contained hundreds of thousands of the bony fish species. However, experts suggest that habitat degradation, overfishing, and declining water quality all contributed to the population decline. The Chesapeake population was declared to be "functionally extirpated" by scientists in the late 1990s as they started writing scientific epitaphs.
By that time, scientists on the Western Shore of the Bay had established that the James River in Virginia was home to a breeding population. Later, on the Pamunkey River, another was confirmed.
In the Nanticoke River in that state, right upstream of Seaford, a fisheries scientist with the Delaware Division of Fish and Wildlife successfully caught a young sturgeon in September. In the Nanticoke-Marshyhope system, it was the first baby sturgeon that researchers had ever caught.
According to Stence, its existence in the Nanticoke is a positive indication that sturgeon are reproducing there. This is so because baby sturgeon stay in their home waters for anywhere from a few months to two years. A location where one is discovered is therefore likely to be the river where it was born. Being anadromous fish, they spend the majority of their life in saltwater beyond their juvenile years, only returning to their native rivers to spawn.
The Atlantic sturgeon's protracted spawning practises are one of the main obstacles that researchers must overcome in order to save the species. By fish standards, it takes them a long time to attain sexual maturity - roughly 10 years for males and close to 20 years for females. Additionally, they are capable of going up to five years without spawning.
Cobble, hard clay, or bedrock are suitable options for the waterway's bottom material since they are firm and allow for the fertilised eggs to adhere to something rather than float away. According to Secor, the Marshyhope's bottom is practically perfect for housing a sturgeon nursery.
He and his colleagues have applied all available scientific tools to the problem of comprehending the Marshyhope's sturgeon. In an effort to catch eggs or larvae, they have placed egg mats on the river bottom, but so far their efforts have been unsuccessful. Sonar has also been utilised to map the best possible habitat on the bottom.
100-yard-long net will be raised out of the water on one end, and the winning team will then hand-pull the shimmering mesh across the deck of their boat to the other end. Success is uncommon. Despite spending hundreds of hours on the water from 2015 to 2018, they averaged six fresh fish catches and four recaptures between the two streams.The main issue for Secor and other opponents was that a chemical called geosmin, formed from bacteria, would be present in huge quantities in the discharged water, which they claimed may upset the delicate aquatic ecology.
In August, Secor voiced his worries in front of the public at a community meeting sponsored by MDE. Additionally, he wrote an unfavourable guest opinion for The Baltimore Sun.
